Welcome to my new blog on IBM Developerworks!
I am Tony Pearson, IBM brand marketing strategy, located in Tucson, Arizona. I have degrees in Computer Engineering and Electrical Engineering from the University of Arizona. Over the past 20 years, I have worked in a variety of storage roles, including development projects, product and portfolio management, testing, field support, and now bring that technical experience to marketing.
There are a lot of things to discuss related to storage, and I am never short of opinions. As such, the standard IBM disclaimer applies: “The postings on this site solely reflect the personal views of the author and do not necessarily represent the views, positions, strategies or opinions of IBM or IBM management.”
I have invited other IBMers to post their opinions, and when they do, their opinions may not necessarily match mine either.
This is an open two-way conversation between IBM, Business Partners, Independent Software Vendors, prospects and existing clients. I encourage everyone to post comments about our products, services, and marketing efforts.
I have created blog categories, based on our System Storage offering matrix, which you can track individually:
- Disk systems, including the IBM System Storage DS Family of products, SAN Volume Controller, N series, as well as features unique to these products, such as FlashCopy, MetroMirror, or SnapLock.
- Tape systems, including the IBM System Storage TS Family of products, tape-related products in the Virtualization Engine portfolio, drives, libraries and even tape media.
- Storage Networking offerings, from Brocade, McData, Cisco and others, such as switches, routers and directors.
- Infrastructure management, including IBM TotalStorage Productivity Center software, IBM Tivoli Provisioning Manager, IBM Tivoli Intelligent Orchestrator, and IBM Tivoli Storage Process Manager.
- Business Continuity, including IBM Tivoli Storage Manager, Tivoli CDP for Files, Productivity Center for Replication software component, Continuous Availability for Windows (CAW), Continuous Availability for AIX (CAA).
- Lifecycle and Retention offerings, including our IBM System Storage DR550, DR550 Express, GPFS, Tivoli Storage Manager Space Management for UNIX, Tivoli Storage Manager HSM for Windows, and DFSMS.
- Storage services, including consulting, assessments, design, deployment, management and outsourcing.
For those who missed it, IBM announced last Tuesday encryption capability for the TS1120 drive, our enterprise tape drive that read and write 3592 cartridges. Do you need special cartridges for this? No! Use the sames ones you have already been using!
You can read more about it www.ibm.com/storage/tape.

This week I was in Dallas, Texas, teaching at the "System Storage Portfolio Top Gun" class.
Can you believe it was hotter and more humid in Dallas than in Tucson? I am glad to be home.
For those unfamiliar with Top Gun classes, it is our top level sales training, typically 4 to 4.5 days long. This year, I have taught Top Gun classes in USA, China, Mexico, Thailand, and Brazil.
The class is open to IBM sales, IBM Business Partners, ibm.com telesales, field support and our technology partners.
We have several more classes for 2006, in Canada and the USA. For more information, read here www.ibm.com[Read More]
I found this item today on the blogosphere: EMC-HP Storage Race Heats Up
In general, people agree that IBM, HP and EMC are the top three vendors in storage,with HDS, Sun and Dell rounding out the top six.
The fun begins when a respected analyst like IDC Corp. publishes their calculations,and individual vendors re-swizzle the results because they are not happy with theirfindings.
I thought it would be helpful to illustrate how this all works. First, you need to comeup with a defintion of what you are going to count. You could count units sold, revenue dollars, or capacity Terabytes, or some other generally accepted metric.
Next, you need to define what's in and what's out. For example, you can say "storage"which would include both disk drives and tape drives, both internal to servers, orexternal to servers, or you can choose a more narrow definition, say external disksystems, which might suit you better if you aren't in the tape business, and don't sell servers.
By some definitions, my Apple iPod, Motorolla cell phone, and Canon digital camera,could all be counted as external disk systems, as they all connect via USB cableto my IBM laptop, and act like a disk drive to my Windows operating system, allowingme to read and write data back and forth. It is necessary to define exactly what you plan to include,and what to exclude, based on the reported numbers available.
The last rule is that nothing gets double-counted. In our complicated industry ofmanufacturers and vendors, sometimes storage is manufactured by one company, but soldby another, typically under the vendor's brand, not the manufacturer's brand. Youcan either count manufactured units, or vendor units, but you can't mix and match.
IBM is both manufacturer and vendor. However, IDC only counts vendor units, so storagemanufactured by someone else, but sold by IBM is counted as IBM, and storage manufacturedby IBM but branded by someone else goes to that other vendor. Likewise, HP and Sun re-brandHitachi storage, and Dell re-brands EMC storage.
EMC would like to treat all EMC-manufactured storage re-branded by Dell as EMC vended storage,so that it can move up in the ratings. But Dell wants to count it too, so that it can appearin the top six. You can't have it both ways.
But are these ratings just "bragging rights"? Not always. When big purchases are planned fornew projects, or a client decides its time to throw out the current vendor and shop for a newone, the ratings could influence that decision. In that regard, IDC 4Q05 Storage Tracker reportedIBM as number one over all in storage hardware at the end of 2005, which includes both internal and external disk systems, as well as tape drives sold under the IBM brand, based on dollar revenues. By this method of counting, HP came in at number 2, EMC at number 3, and the rest round out thetop six as before.
In the end, this is just one factor when deciding which brand to choose for your storage needs.

Here's an interesting article in Raptured Monkey: Big Blue...Big Borg!
The author is wondering whether EMC will try to avoid the fate of Hitachi's mainframebusiness, focusing on "moving into the IBM field" of offering software and services for more complete solutions.
Interestingly, one comment opines that EMC's acquisition of Documentum was "followed" byIBM's acquisition of FileNet, not realizing that IBM already has the leading documentmanagement software (IBM Content Manager).
Another comment cites IBM's recent push of Xen asanother example "following" EMC's acquisition of VMware, again not realizing that IBM has hadLogical Partition (LPAR) capability in its System z, System p and System i server lines formany years.

I've only had this blog since Sep. 1, and already it is listed in the Data Storage Bloggers wiki list.
In last week's System Storage Portfolio Top Gun class in Dallas, some of the students were not familiarwith Really Simple Syndication (RSS). For the uninitiated, this can be intimidating.I thought a quick overview of what I've done might help:
- Chose a "feed reader". I chose Bloglines but there are many others.
- Use Technorati to search other blogs for keywords or phrases I am looking for.
- When I find a blog that I like to continue tracking, I "add" it to my subscription list on bloglines. Just hit "add" and copy the URL of the blog you want to track. Bloglines will figure out the RSS keywords required.I track eight blogs at the momemnt, but some people with lots of time on their hands track 20 or more. It is easy to unsubscribe, so don't be afraid to try some out for a few days.
- Since I was actually going to run a blog of my own, I read a few books on the topic. One I recommend is "Naked Conversations" by Robert Scoble and Shel Israel, both experienced bloggers.
- Finally, I am not big on spell checking, but most places have the option to preview your post or comment before it actually gets posted, which is not a bad idea if you use any HTML tags.
For a quick taste of blogging, consider using Data Storage Blogger Feed Reader. This has a lot of blogs on the topic of storage, already added and categorized for your convenience, ready for your perusal.
I am sure there are many other ways to enjoy the Blogosphere, but this works for me.[Read More]
Dave Hitz from Network Appliance has a wonderful discussion of "branding": What do Marketing People Mean When They Say Brand?
A lot of people ask me about IBM branding, as we have recently changed brands. In the past we had two separate brands, one for servers (eServer) and one for storage (TotalStorage). These would be fine if we wanted to promote their independence, but customers today want synergy between servers and storage, they want systems that work well together.
Last year, in response to market feedback, we crated a new brand, "IBM Systems" and put all the server and storage product lines under one roof. Over time, we will transition from TotalStorage to System Storage naming. This will occur with new products, and major versions of existing products.
Two other phrases you will hear in the names of our offerings are "Virtualization Engine" and "Express". These are portfolio identifiers. The Virtualization Engine identifier was created to emphasize our leadership in system virtualization, and we have products that span product lines with this identifier.
The Express identifier was created to emphasize our focus on Small and Medium sized business (SMB). It spans not just servers and storage, but across other offerings from other IBM divisions.
Of course, just renaming products and services isn't enough. Systems don't work together just because they have similar names, are covered in similar "Apple white" plastic, or have similar black bezels. Obviously, thoughtful and collaborative design are needed, with the appropriate amounts of engineering and testing. IBM is aligning its server and storage development so that the IBM Systems brand keeps its promise.

Tony Asaro has a nice piece about Confirmation Bias
There's nothing worse that feeling you made a bad decision.My favorite is buying something, and then finding it at a lower price somewhere else. Or worse,being in a country where you haggle over prices, and finding out that I might havebeen able to haggle further down than what I had paid.
Of course, the solution to making better, more informed decisions, is getting more information.That's what I love about being in the storage business.[Read More]
Well,This is completely off-topic, but now that I have a bluetooth-enabled Thinkpad T60, I have been interested in this new wireless technology. I have a bluetooth cell phone, a bluetooth wireless headset, and my thinkpad, and they all work together seemlessly. I am able to speak on my cell phone through my headset, listen to music and videos on my laptop through my headset, and even dial in to the IBM network through my cell phone, all without any cables!
A variation of the Wi-Fi soup-cantenna has emerged to intercepting bluetooth signals. Check out this coolBlueSniper Rifle
Now that's innovation.[Read More]
My colleague Cyrus pointed me to this ComputerWorld article: Users suffer major problems with Symantec NetBackup 6.0
Which reminds me of the old adage frequently said by Mike Hartung, IBM Fellow:
Eventually hardware fails, ...
... eventually software works.
For a solid backup product, consider usingIBM Tivoli Storage Manager.I use it to protect all my data on my laptop. And when switching recently from my old Thinkpad T30 to my newThinkpad T60, used it to transfer my data over as well.[Read More]
Steve Rubel has an interesting blog on Wikipedia: Wikipedia Is More Popular Than...
When I was a kid, we didn't have online access to anything. Either yourparents were rich and generous and bought you the latest set of encyclopedias, or they were poor or cheap, and you hoofed it to thenearest library.
Now, I rely heavily on Wikipedia, and other wikis, to find information I need.The key here is the ability to find stuff. With the old 27-volume set ofencyclopedias, you had to know what word something would be filed under, andhow to spell it, so that you could find it. Today's search facilities are much moreforgiving. If you guess wrong, you are only a few clicks away from what youwere really looking for, in a Kevin Bacon six-degrees-of-separation kind of way.
Wikipedia is now looked at more often than CNN.com or the New York Times website.Why? It is amazingly good at summarizing a situation in succinct terms, even fornews "as it happens". The recent episode at Heathrow airport a few weeks agoserves as a good example. I was in Washington DC that week, on my way to Miami and Sao Paulo,Brazil, so it is good to have the news I needed, when I needed it.[Read More]
Yesterday (September 7, 2006) the Eclipse Foundation
announced that it has approved the creation of the Aperi Storage Management Framework Project.
There's been a lot of confusion out there about Aperi, so I thought I would post some facts and opinions about this exciting new project. A few years ago, I was thelead architect for IBM TotalStorage Productivity Center, IBM's infrastructure management product that helped launch the creation of Aperi.
From the latin word for "open", Aperi is an open source project that aims to simplify the management of storage environments, using the Storage Management Initiative - Specification (SMI-S) open standardto promote interoperability and eliminate complexity in today’s storage environments.
Aperi should provide immediate value upon install with basic storage management capabilities, rather than just simply a collection of components that require costly integration. We've discussed requirements for functions such as:
- Resource discovery, monitoring, and reporting
- Fabric Topology mapping
- Event management
- Disk / Tape management
- Device configuration & LUN assignment
- SAN fabric management
- Basic asset management
- User Interface
The big confusion most people have is Aperi's relation to SMI-S and the Storage Networking Industry Association (SNIA)open standards group. The best way to explain this is to go backto your High School SAT college-entrance exams. Remember questions like this?
CRUMB : BREAD ::
(A) splinter : wood
(B) water : bucket
(C) cream : butter
(The answer: a crumb is to bread like a splinter is to wood.)
Aperi is an implementation of SMI-S standard, similar to MySQL or PostgreSQL areopen standard relational database implementations of Structured Query Language (SQL).These compete with proprietary database implementations such as IBM DB2 Universal Database,Oracle Database, Microsoft SQL Server, or Sybase.
Aperi: SMI-S ::
PostgreSQL : Structured Query Language (SQL)
It is often the case that the folks writing the code are different than the folks defining the standards. This is the case between the members of Aperi writing code, and the members of the SNIA writing standards. IBM happens tohave employees writing Aperi code, and other employees helping define SMI-S standards.What can I say, IBM is a big company and a leader in many areas.
A good analogyis how the Apache community has developed an awesome web server, and the Firefox Mozillacommunity have developed an awesome web browser, both of which are implementations of the HTTP/HTML standards adopted by the World Wide Web Consortium. Apache and Firefoxcompete with proprietary implementations, such as Microsoft Internet Information Services(IIS) web server and Internet Explorer web browser.
Aperi: SNIA ::
Apache : World Wide Web (WWW) Consortium
With this arrangement, Aperi and the SNIA will have very complementary roles in defining and driving standards across the entire storage market. To that end, Aperi will make extensive use of the SNIA’s Technology Center and SNIA’s “plugfests” to test the interoperability of the Aperi framework with the variety of 3rd-party storage offerings available. By providing a tested implementation of SMI-S, Aperi will drive broader industry availability of SMI-S, as well as offer the many benefits of an industry-backed open source community.
Check out this vote of confidence:
"Eclipse's Aperi Project will further advance the adoption of SNIA's SMI-S, benefiting the entire storage industry and IT community. Furthermore, the SNIA and Aperi will define plans to collaborate on new storage standards, standards testing programs, and storage interoperability programs."
--- Wayne M. Adams, chair, SNIA Board of directors
So, both proprietary and open source implementations have their place in the world.Proprietary products are needed for advanced, unique value-add, and opensource projects are for basic support focused on interoperability and flexibility.These can be combined, for example, proprietary "plug-ins" built on an open source base. The more choices the client has, the better.
Storage vendors benefit too. Vendors are tired of being in the "Y.A.C." business, building "Yet Another Configurator" for each new device developed, with basic functionsto carve LUNs, read performance stats, and so on. By shipping Aperi instead, storagevendors like IBM can invest their development dollars in real innovations, things thatmatter for the customer.
If you are unfamiliar withopen source, I highly recommend Eric Raymond's bookThe Cathedral and the Bazaar. It might just change the way you think aboutopen source usage in the workplace.

A few years ago, I was the IBM portfolio manager for storage connected to BladeCenter solutions. I learned a lot about the BladeCenter design, and got to speak at various x86 server events.
My colleague John put together a nice webpage on storage for System x and BladeCenter servers:
IBM System Storage for System x
BladeCenterservers come in many flavors, including blades with Intel, AMD and POWER chipsets, and can be configured in Grid and SuperComputer configurations. Up to 14 blade servers can fit intoa single 7U-high chassis, making this twice as dense as standard 1U-high rack-mounted servers.
System x, the new "IBM Systems" name for our popular xSeries product line, support Intel and AMD chipsets. These come in both rack-mountedand tower configurations. These also are idea for clustered and SuperComputer configurations.[Read More]
My colleagues have put up a nice new company-wide webpage to explain IBM's new IT Service Management initiative (ITSM):www.ibm.com/itsm
, including a video interview with Nancy Pearson (no relation).
Of course, storage management is a big part of this, and products like IBM TotalStorage Productivity Center play a key role.
But ITSM is more than just a better way to manage operational tasks, it is focused on the best practices of the IT Infrastructure Library (ITIL) which has been adopted bythe European Union, and now being adopted worldwide by both government agencies and private enterprises as a smartway to run your IT environment.
Last year, we talked about storage provisioning andorchestration.This year, we bring it up a notch, introducing IBM Tivoli Storage Process Manager. Of all the talk we gave the past decade on the promises of "autonomic computing", it's initiatives like IBM Service Management that give it real meaning.
Of course, we've designed our solutions to apply to your entire IT environment, supporting both IBM and non-IBM equipment, so even if not all of your servers and storage come from IBM, at least your software can be.[Read More]

Last week, Steve Jobs demonstrated the latest evidence that theinmates are running the asylum
over at Apple
I wasn't at the event, but thought it would be good to explain some basic concepts ofInformation Lifecycle Management (ILM),using the files on my iPod as an example. (Disclosure: IBM makes the technology inside many of Apple's computers, and so IBMers get to buy Appleproducts at employee prices. I own a Mac Mini based on IBM's POWER4 processor, and an iPod Photo 60GB model).
I have 20,000 MP3 music files, representing 106GB of data. This fits nicely on my 250GB external disk system attached to my Mac Mini, but won't all fit on my little 60GB iPod. I needed a way to decide what music I keep on bothmy iPod and Mac Mini, and which I keep only on my Mac Mini. When I am traveling, I am able to listen only to the musicin the first group, but when I am at home, I am able to listen to all my music in both groups.(Another disclosure: I use my Tivo connected to my LAN to play all my MP3 music through my home stereo system.I had my entire house wired with Cat5 to make this possible.)
Apple's iTunes software lets me decide which MP3 files are copied to my iPod using "playlists". A playlist is a list of songs. Fixed playlists are created manually, each song copied to its list in a specific order. Smart playlists are createdautomatically, via policy. I give it the criteria, and it finds the songs for me. If I import a new music CD,none of the songs will be added to any fixed playlists, but could be added to my smart playlists if I set the policiescorrectly. Apple iTunes supports both "include" and "exclude" methodologies.
I use primarily smart playlists, based on genre and rating. I have tried to keep the number of genre down to a small manageable list:
- Rhythm & Blues
- Hip Hop
Of course, what I have for genre may not match what's in theGracenote
database, so I sometimes have to makeupdates to match my convention. I've picked these based on my different "applications" for my music. For example, I listen to Ambient music to help me fall asleep on airplanes, but Rock when I exercise at the gym.
Next, I use the ratings from one to five stars. The advantage to the rating is that I can change them on-the-fly directly on my iPod. All other "metadata" has to be entered only from the keyboard of my Mac Mini.
|*||Files for Mac Mini only, not copied to my iPod|
|**||Non-mix, copied to my iPod, but typically spoken words, such as language lessons|
|***||Mix, music to include in my music mixes|
|****||Keep on my iPod, but re-evaluate|
So, I have five smart playlists, "One Star", "Two Stars", etc. for each rating, and have decidedto keep only the 2, 3, 4 and 5 star songs on my iPod, by simply putting check marks on those playlists to copythem over. I have about 50 songs with 5 stars, and 8000 with 3 stars, and the rest in the other categories,leaving me a few GB to spare.
I also have playlists for each genre, "Rock mix", "Pop Mix", "Ambient Mix", etc. where I have selected thosethat match the genre, AND have 3, 4 or 5 stars. In this manner, I can listen to a mix. If I find a song mis-classified for that genre, I change it to four stars, which serves as myreminder to re-evaluate when I am back at home on my Mac Mini. If I don't want a song in my mix, I just lowerit to 2 stars. I want it off my iPod altogether, I lower it to one star.
This method is simple enough, and allows me to enjoy my music right away, and more effectively, without having to wait for completely finishing my classification process.
Next week, I'm traveling to Africa (purely vacation, not related to my job, my senator, or myinvolvement in anycharitable organizations). My Canon camera has only a 1GB IBM Microdrive, but I am able to offloadmy pictures to my iPod, connected via USB cable, and review the pictures on the little 2-inch screen. By simply "unchecking" my 2-star and 3-starplaylists, and checking only those mixes I plan to take with me, I was able to clear 17GB of space, plenty ofroom for all my photos of elephants and giraffes, but still plenty of music to listen to. Thanks to my simple methodology, I was able to do this with minimal effort, and willhave no problem putting all my music back when I return.
When evaluating an ILM process, many people are overwhelmed by their fear of the classification process, when in reality it doesn't have to be so complicated.
Is there an "iTunes" for the storage in your datacenter? Yes! It's called IBM TotalStorage Productivity Center. It can help you list and classify all the files in your IT environment,including files in your internal disks inside the servers, your NAS and SAN external disk systems, across both IBM and non-IBM hardware.It's a good thing to consider as part of your overall ILM strategy.

Hello Everyone! I am back from my safari vacation in Kenya.
One of the interesting parts of the journey was to visit a village of the Samburu tribe. Each village is a circle of huts surrounded by thorned branches to keep the wild lions out. In the center is another ring of thorned branches to keep all the cattle, sheep and goats.
One of the tribewomen invited us to show us her home. Each hut is made of sticks, stuck into the ground and then woven with other sticks, then covered in cow dung along the walls, and scraps of cardboard and newspaper as the roof.
Although the hut looks small from the outside, it was surprisingly roomy inside; it was divided into four rooms or partitions. The first was for the adults, the second for children, and the third for newborn animals and sometimes relatives visiting from other villages.
I asked what was the fourth room used for, and of course, her answer was: Storage.[Read More]
The TS3100 Tape Library
An astute reader brought this to my attention. The newest addition to our "IBM Express Portfolio"set of SMB-oriented offerings is the new TS3100 tape library. This has one LTO Gen 3 drive and up to 22 cartridges, which can be a mix of WORM and rewriteable cartridges,beautifully packaged in a small 2U high (3.5 inch) rack-mountable chassis. Each cartridge can hold up to 800GB uncompressed, or 1.6TB with typical 2-to-1 compression.
This tape library would be a great complement to TSM Express for backup, and to theDR550 Express for archive and compliance storage.
And now, for a limited time, there is a $1500 rebate, check website for details.

IBM has bundled our midrange DS4000 disk with SAN networking switch in a convenient 42U-high rack, and nicknamed thisSAN-in-a-can
In SearchDataCenter.com, Matt Stanberry's article Sun rolls out data center Winnebago indicates Sun has taken IBM's SAN-in-a-can concept to the next level.
This is an interesting development. To understand it better, we need to go back to the 1930s. Malcolm McLean invented the shipping container in the 1930s in New Jersey, and later founded Sea-Land corporation. Rather than unpacking products from a ship, load onto a truck, then move those products onto a train, his innovation was to create a container that could be packed full of products, carried from ship, to truck, to train, without loading and unloading individual products as transportation means change. He named the size of his container "TEU".
TEU = 20 ft x 8.5 ft x 8.5 ft
(twenty-foot equivalent unit)
In 1966, the standard shape and size was adopted by International Organization for Standardization (ISO).Today, over 90% of freight containers are 1 or 2 TEU
Sun's announcement is that they have packed up to 240 UNIX servers into a single TEU container. This can be dropped off at your facility, hook up your power and cooling, and start running. An alternative version is a disk-farm-in-a-can, having the TEU container filled with up to 2 PB of disk storage capacity.

For those of you worried about my mysterious absence on the blogosphere, I am getting better. Sorry for not posting much lately, I have had more serious issues to worry about. I am awaiting results on whether I have Dengue fever from Brazil, Avian flu from Thailand, Malaria from Kenya, or perhaps it is just food poisoning from the otherwise fabulous French cuisine I ate last week in the South Pacific. Well, I am back in town for a while, and hopefully will recover to full health, and have some time to reflect my thoughts on storage topics.
Speaking of which, a lot has happened while I was out. Let's take a quick look.
- Following our introduction of the world's first encryption-capable tape drive, the TS1120, IBM now offers higher capacity 700GB cartridges, in standard 3592 format.
- The DS8000 Turbo disk system now is being offered with a flexible choice of warranty periods, 1-year, 2-year, 3-year and 4-year. Since IBM was the only one to offer 4-year warranties, it was sometimes difficult to compare apples-to-apples with our competition that offered lesser warranty periods. Now, we can match the warranty period you need, so the focus can shift on the added value the DS8000 Turbo provides at the right price.
- IBM's newest low-end half-high tape drive, the TS2230 Tape Drive Express Model H3L, part of our Express portfolio of offerings designed for small and medium-sized businesses (SMB). It supports the latest LTO Generation 3 specification, so fully compatible with our larger tape systems, as well as the LTO-based gear from HP and Quantum.

Our industry is full of acronyms, and sometimes spelling out what words an acronym stands for is not enough to explain it fully.
It reminds me of an old story within IBM. A customer engineer (or "CE" for short) was repairing an air-cooled server, and found the failing part being a "FAN". Not knowing what this stood for, he looked up the acronym in the offical "IBM list of acronyms" and found that it stood for "Forced Air Network". Apparently, so many people did not realize that a FAN was just a "fan" that they needed to add an entry to remind people what this little motorized propeller was for.
This brings me to Tony Asaro's Fun with FAN blog entry which mentions yet another definition for FAN, that of "File Area Network". The concept is not new, but some developments this year help make it more a reality.
- IBM's General Parallel File System (GPFS) has been enhanced earlier this year with cool ILM-like functionality borrowed from SAN File System, such as policy-based data placement, movement and automatic expiration. This can include policies to place data on the fastest Fibre Channel drives at first, then move them to slower less costly SATA disks after a few months when fewer access reqeusts are expected.
- IBM has paired up N series with SAN Volume Controller (SVC), so that an N series gateway can now provide iSCSI, CIFS and NFS access to virtual disks presented from SVC. The problem with NAS appliances in the past, is that once they fill up, moving files to newer technologies is awkward and difficult. With SVC, file systems can now be moved from one physical disk system to another, all while applications are reading and writing data.
To better understand the importance of this, consider the first "FAN", the mainframe z/OS operating system using DFSMS. The mainframe uses the concept of "data sets", a data set can be a stream of fixed 80-character records, representing the original punched cards, a library of related documents, or a random-access data base. All mainframes in a system complex, or "sysplex" for short, could look up the location of any data set, and access it directly. Data sets could be moved from one disk system to another, migrated off to tape, and brought back to disk, all without re-writing any applications.
To join the rest of the world, new types of data set were created for the z/OS operating system, known as HFS and zFS. These held file systems in the sense we know them today, comparable in hierarchical organization of files on Windows, Linux and UNIX platforms. These could be linked and mounted together in larger hierarchical structures across the sysplex.
The concept of files and file systems is a fairly new concept. Prior to this, applications read and wrote directly in terms of blocks, typically fixed length multiples of 512 bytes. For a while, database management systems offered a choice, direct block access or file level access. The former may have offered slightly better performance, but the latter was easier to administer. Without file system, specialized tools were often required to diagnose and fix problems on block-oriented "raw logical" volumes.
This launched a "my file system is better than yours" war which continues today. The official standard is POSIX, but every file system tries to give some proprietary advantage by offering unique features. Sun's file system offers support for "sparse" files, which is ideal for certain mathematical processing of tables. Microsoft's NTFS offers biult-in compression, designed for the laptop user. IBM's JFS2 and Linux's EXT3 file systems support journaling, which tracks updates to file system structures in a separate journal to minimize data corruption in the event of a power outage, and thus speed up the re-boot process. Anyone who has ever waited for a "Scan Disk" or "fsck" process to finish knows what I'm talking about. Of course, if an application deviates from POSIX standards, and exploits some unique feature of a file system, it then limits its portability and market appeal.
The two competing NAS file systems are also different. Common Internet File System (CIFS) was developed initially by IBM and Microsoft to provide interoperability between DOS, Windows and OS/2. Meanwhile, Network File System (NFS) was the darling of nearly every UNIX and Linux distribution, and even has clients on operating platforms as diverse as MacOS, i5/OS, and z/OS. Today, nearly every platform supports one or both of these standards.
Bottom line, file systems are here to stay. Any slight advantages to use raw logical volumes for databases and applications are losing out to the robust set of file system utilities that can be used across a broad set of platforms and applications.

Ken Gibson has written a four-part series about where the storage industry is going, on his Storage Thoughts blog. You can find the four parts here (Part 1
His analysis of the storage industry is based on the concepts in Clayton Christensen's latest book Seeing What's Next, his latest work on the heels of his last two successes "The Innovator's Dilemma" and "The Innovator's Solution". I've only read the first book, "The Innovator's Dilemma" but need to check out these other two.
Ken explores the efforts of the incumbent players, and I agree IBM is farthest along, but not only for our "Storage Tank" architecture. For those not aware of Storage Tank, it was the code-name of a project from IBM's Almaden Research Center, productized as IBM System Storage SAN File System (SFS). Earlier this year the advanced policy-based data placement, movement and expiration features of SFS were copied over to IBM's General Parallel File System (GPFS) which has wide adoption among the High-Performance Technical Computing (HPTC) community. As I've said before, switching from one file system to another is hard, so it makes sense for HPTC clients who already use GPFS to make use of these new features by staying with GPFS, rather than trying to get them to move to SFS.
I also like Ken's analysis of "overshot" and "undershot" clients. Overshot clients are those that find what the marketplace delivers already "good enough" for their needs, and are price sensitive against paying for features they don't think they need. The undershot clients are those that the current marketplace set of offerings are not yet good enough, and are willing to pay a premium to the vendor or supplier that can get them closer to what they are looking for.
Changes are underfoot, and it is an exciting time to be involved in the storage industry.[Read More]
Last week, David Pogue (New York Times) wrote a blog entry on The Dilemma Over Future Storage Formats
Of course, he is focused on the home user, and not the bigger mess found in the corporate world, where Federal Rules like the one past last week that begin to mandate that all U.S. companies archive every e-mail and instant message (IM) generated by their employees.
However, the article does bring up issues that effect the corporate world as well. Its not the "format" as much as the medium/player interface. A friend of mine just bought a vintage 8-track-tape player, but has only one 8-track tape to try it out with. He is now looking on eBay for other 8-track tapes.
The idea of keeping old drives around to read back data is not new. A company called eMag Solutions has all kinds of older tape drives to help companiesretrieve data on their older 3420 and 3480 tape cartridges.
The problem is not just accessing the data on the media, but rendering the "ones" and "zeros" into meaningful information. For example, suppose I saved a copy of my Quicken Tax file every year, and copied them onto a singleDVD for long term storage. The problem is that to access 2002 tax data, I have to run that version of the Quicken 2002 program, and hopefully that version will run on my current computer equipment and operating system.
A client I visited earlier this year had to retrieve 4-year-old Oracle data for litigation reasons. However, to make sense of the data, they had to build a server with a down-level version of AIX and down-level version of Oracle to match the level supported by their homegrown application.
One solution might be to find a new format that is application-independent. Flat text files, Adobe PDF format, MP3 audio files, HTML pages, and JPEG photo images are often used to avoid the requirement of special applications to make sense of the data.Unfortunately, in some countries, the laws actually dictate that business must keep their data in the original "digital format". So, if it was a MS WORD v1 document, it must be kept in v1 format, even though today's WORD 2002 can't even make sense of it, and you have to go to IBM or some other third party that have "rendering tools" that understand these older formats.
Luckily, for the corporate world, IBM has a lot of experience in this area, is the leader in Content Management, offers the world's fastest archive/compliance storage, the DR550, clocked at three times faster than the EMC Centera, WORM tape on LTO Generation 3 and 3592 tape cartridges, and software designed to render older formats into readable form.
For the home user, IBM's recent "Innovation Jam" identified this as one of the top 10 ideas, the idea of "Digital Me", storing not just old tax documents, but photos, music, home videos, and so on. My aunt Nancy passed away, leaving me a box of old VHS tapes, which I will watch this month as I sort through all my paper receipts getting ready to file for 2006 taxes.

Chris Anderson, of Wired magazine, wrote a great article called The Long Tail
This article became a book by the same name published earlier this year, and I just discovered it on a recent visit to Second Life. A lot of IBMers are now alsoSecond Lifers, and I suspect it is just a matter of time before we are conductingour customer briefings there, and getting our year-end bonuses paid directly in Linden bucks.(Those of you not familiar with Second Life can watch this 3-minute video fromthe folks at Text100)
Anyways, the Long Tail describes the new economy of entertainment thanks to digitalstorage. Here are some of the key insights.
- In the past, entertainment was all about hits: hit songs, hit movies,hit novels, and this was primarily because of the economic realities restricted byphysical space. Chris writes: "An average movie theater will not show a film unless it can attract at least 1,500 people over a two-week run; that's essentially the rent for a screen. An average record store needs to sell at least two copies of a CD per year to make it worth carrying; that's the rent for a half inch of shelf space."
- Things have changed. To drive the point home, Robbie Vann-Adibe (CEO of eCast), poses the trick question"What percentage of the top 10,000 titles in any online media store (Netflix, iTunes, Amazon, or any other) will rent or sell at least once a month?" The answer will surprise you. Write down your guess first, then go read here. His digital jukeboxes are able to play from a list of150,000 songs, not the few hundred you'd find at the Tap Room which is rated as having the best jukebox in Tucson.
- The phenomenon is not just limited to music. "Take books," Chris writes, "The average Barnes & Noble carries 130,000 titles. Yet more than half of Amazon's book sales come from outside its top 130,000 titles. Consider the implication: If the Amazon statistics are any guide, the market for books that are not even sold in the average bookstore is larger than the market for those that are..."
This has incredible implications for the storage industry. For one, content providers are going to dig deep into their archives to digitize and deliver "long tail" offerings. If they don't have a deep archive, many will start to build one. Second, the need to search through that large volume of content will become more critical. Classifying and indexing with the appropriate tags and metadata will be an important task.

On SearchStorage.com, my buddy Tony Asaro recaps the latest Storage Acquisition Frenzy
It has always been the case in fast pace technology areas that you can't tell the players without a program card, andthis is especially true for storage.
When analyzing each acquistion move, you need to think of what is driving it. What are the motives?Having been in the storage business 20 years now, and seen my share of acquisitions, both from within IBM,as well as competition, I have come up with the following list of motives.
Although slavery was abolished in the US back in the 1800's, and centuries earlier everywhere else, many acquisitionsseem to be focused on acquiring the people themselves, rather than the products or client list. I have seen statistics such as "We retained 98% of the people!" In reality, these retentions usually involve costly incentives,sign-in bonuses, stock options, and the like. Desptie this, people leave after a few years, often because ofpersonality or "corporate culture" clash. For example, many former STK employees seem to be leaving after their company was acquired by Sun Microsystems.
If you can't beat them, join them. Acquisitions can often be used by one company to raise its ranking in marketshare, eliminating smaller competitors. And now that you have acquired their client list, perhaps you can sellthem more of your original set of products!
Symantec had acquired Veritas, which in turn had acquired a variety of other smaller players, and the end result is that they are now #1 backup software provider, even though none of theirproducts holds a candle to IBM's Tivoli Storage Manager. Meanwhile, EMC acquired Avamar to try to get more into the backup/recovery game, but most analysts still find EMC down in the #4 or #5 place in this category.
Next month,Brocade's acquisition of McData should take effect, furthering its marketshare in SAN switch equipment.
Prior to my current role as "brand market strategist" for System Storage, I was a "portfolio manager" where wetried to make sure that our storage product line investments were balanced. This was a tough job, as the investmentshad to balance the right development investments into different technologies, including patent portfolios.Despite IBM's huge research budget, I am not surprised that some clever inventions of new technologies comefrom smaller companies, that then get acquired once their results appear viable.
- Value Shift
The last motive is value shift. This is where companies try to re-invent themselves, or find that they are stuck in acommodity market rut, and wish to expand into more profitable areas.
LSI Logic acquisition of StoreAge is a good exampleof this. Most of the major storage vendors have already shifted to software and services to provide customer value,as predicted in 1990's by Clayton Christensen in his book "The Innovator's Dilemma". The rest are still strugglingto develop the right strategy, but leaning in this general direction.
I hope that provides some insight.[Read More]
On his "Data Storage - Dullness becomes Mainstream" blog, Chris Evans is
amazed athow low they can go!
.He compares the latest 100GB Toshiba 1.8" drive designed for portable music players, to the size andweight of older technology, like the IBM 3380 Direct Access Storage Device (DASD).
Chris couldn't find the dimensions of the 3380, so I thought I would provide the missing detail.The IBM 3380 History Archivesprovides a nice summary:
- The CJ2 model that Chris mentions was announced September 1, 1987 and shipped in 1988. Earlier models of the 3380 were announced 1980-1986.
- Capacity and performance were measured in 7-bit "characters", since we were not yet storing full 8-bit bytes.
- By today's standards, having such a large box to hold a few GB might seem amusing, but at the time, this unit was four times the capacity as its predecessor, the IBM 3350 DASD. Compare that with our first disk system, the IBM 350 Disk Storage Unit, introduced in 1956, that stored only 5 million characters (5MB) and was the size of two refrigerators.
- The term "DASD", pronounced daz-dee, was used as some earlier devices were based on magnetic drums or strips of magnetic tape. Today, DASD is still a common term for disk systems among mainframe administrators.
- The 3380 was also twice as fast as the IBM 3350, at 3 million characters per second (3 MB/sec). The irony was thatthe mainframe servers could not keep up, so a Speed Matching Buffer feature was invented to slow it down to half-speed, when used with certain models of mainframe.
As for the dimensions, I too had a hard time finding a publicly available resource that listed 3380 dimensions,so I searched internal IBM resources, and finally, asked someone over in the next building just to measure one ofthe 3380K models we still have in the Tucson test lab floor. The dimensions are ... (drumroll please)
- 70 inches (1778mm) tall
- 44 inches (1117mm) wide
- 32 inches (812mm) deep
The result is that the box could actually hold a much more impressive 52,500 of the new Toshiba drives, twicethe original, albeit conservative, estimate. Before anyone"tries this at home", however, keep in mind that around each Toshiba drive,as with any ATA drive, you need to have all the electronics to communicate to the outside world, and provide cooling. Running tens of thousands of these little guys in the spaceof 60 square feet would probably melt the floor or set off your smoke alarm system.
At least take a backup first.

I got an interesting email from a new blogger asking me for advice on how frequently to post entries.I am probably not the right person to ask, as I blog whenever a thought comes to mind that I think otherswould enjoy reading, and sometimes that means several times a day, and other times only a few per month.I actually have a day job, busy doing other things, and blogging is just now part of my general set of activities.My focus is quality not quantity.
With that in mind, I was delightfully surprised that this blog was ranked among theTop 10 Storage Blogs by Network World, which explains my recent spike in traffic.
I shared the news with my 72-year-old father, and he exclaimed "There are actually 10 or more blogsto cover the IT storage industry?" He couldn't understand why the world would read more than two or three. I personally track thirty-five of them, and I suspect there are hundredsothers out there. Of these, some blog quite regularly, while others do not, so I am in good company. Deni Connor, the author who selected these top 10, gave a nice general complement tothe entire list of blogs:
The blogs written by storage company executives can be surprisingly vendor-agnostic, though the analysts and consultants still tend to pull fewer punches.
And this was my goal as well, to enlighten and entertain, in a fair and balanced manner, that adds value to the blogosphere, rather than just repeat the IBM press releases of each day. If you are just looking for "announcements" there is an RSS feed for IBM System Storage you cansubscribe to.
Not surprisingly, two of the blog entries that Deni mentions are the ones I get the most comments on:
- ILM for my iPod tried to explain Information Lifecycle Management (ILM) into laymen terms that everyone could understand. As an engineer-turned-marketeer, explaining technology and concepts into laymen terms is something I find myself doing a lot to help others grasp what is otherwise rather complex industry we are in. Not surprisingly, many IBMers were not aware they were eligible for discounts on Apple products like the iPod, and thanked me for pointing them to this.
- Aperi is "Viagra" for SMI-S which has now become my infamous blog entry within the halls of IBM. I chose this term over "steroids" given the various scandals involving famous athletes that were going on at the time. To this day,if you search Google for "Tony Pearson" AND "Viagra" you get this blog entry at the top of the list. Oneco-worker overheard that I had "used Viagra" only to later find out they were referring to the fact that I "used Viagra as a metaphor in the title of a blog entry". And that was the real issue, not that I used the term in a popular vernacular that might not translate well into other languages, or that I failed to attribute this as a trademark that belonged to its respective manufacturer, but that it was in the title itself, and thus the URL became "aperi_is_viagra_for_smi" when published in newspapers and press releases. I have since learned to be more careful when phrasing the titles of my blog entries.
I began my year-end vacation today, but like exercising at the gym, I will try to keep up with my blogging over these next two weeks. Especially for those readers out there doing end-of-year storage infrastructure changes. This blog is for you.[Read More
Last week, in my posting on Toshiba's latest 1.8" drive
, Robert Pearson asks:
You may not be the right person to ask but I am asking everyone so "How do you see hybrid disk drives?"
(For the record, I am not immediately related to Robert. At onepoint, "Pearson" was the 12th most common surname in the USA, but now doesn't even make the Top 100.)
Robert, I would like to encourage you and everyone else to ask questions, don't worry if I am the wrong person to ask, asprobably I know the right person within IBM. Some people have called me the "Kevin Bacon" of Storage,as I am often less than six degrees away from the right person, having worked in IBM Storage for over 20 years.
For those not familiar with hybrid drives, there is a good write-up in Wikipedia.
Unfortunately, most of the people I would consult on this question, such as those from Market Intelligence or Research, are on vacation for the holidays, so, Robert, I will have to rely on my trusted 78-card Tarot deck and answer you with a five-card throw.
- Your first card, Robert, is the Hermit. This card represents "introspection". The best I/O is no I/O, which means that if applications can keep the information they need inside server memory, you can avoid the bus bandwidth limitations to going to external storage devices. Where external storage makes sense is when data is shared between servers, or when the single server is limited to a set amount of internal memory. So, consider maxing out the memory in your server first (IBM would be glad to sell you more internal memory!!!), then consider outside solid-state or hybrid devices. Windows for example has an architectural limit of 4GB.
- Your second card, Robert, is the Four of Cups, representing "apathy".On the card, you see three cups together, with the fourth cup being delivered from a cloud. This reminds me thatwe have three storage tiers already (memory,disk,tape), and introducing a fourth tier into the mix may not garnermuch excitement. For the mainframe, IBM introduced a Solid-State Device, call the Coupling Facility, which can be accessed from multipleSystem z servers. It is used heavily by DFSMS and DB2 to hold shared information. However, given some customer's apathytowards Information Lifecycle Management which includes "tiered storage", introducing yet another tier that forcespeople to decide what data goes where may be another challenge.
- Your third card, Robert, is the Chariot, which represents "Speed, Determination,and Will". In some cases, solid state disk are faster for reading, but can be slower for writing. In the case of ahybrid drive, where the memory acts as a front-end cache, read-hits would be faster, but read-misses might be slower.While the idea of stopping the drives during inactivity will reduce power consumption, spinning up and slowing downthe disk may incur additional performance penalties. At the time of this post, the fastest disk system remains the IBM SAN Volume Controller, based on SPC-1 and SPC-2 benchmarks in excess of those published for other devices.
- Your fourth card, Robert, is the Eight of Pentacles, which represents"Diligence, Hard work". The pentacles are coins with five-sided stars on them, and this often represents money.Our research team has projected that spinning disk will continue to be a viable and profitable storage media for at least anothereight years.
- Your fifth and last card, Robert, is the World, which normallyrepresents "Accomplishment", but since it is turned upside down, the meaning is reversed to "Limitation". Some Hybriddisks, and some types of solid state memory in general, do have limitations in the number of write cycles they can handle. For thoseunhappy with the frequency and slowness for rebuilds on SATA disk may find similar problems with hybrid drives.For that reason, businesses may not trust using hybrid drives for their busiest, mission-critical applications, but certainlymight use it for archive data with lower write-cycle requirements.
The tarot cards are never wrong, but certainly interpretations of the cards can be.

Well, there's little to no chance we'll get snow in Tucson the rest of this year, so I built a snowman out in Second Life. That's my avatar on the right, andI am an eightbar specialist. Eightbar refers to our logo.
This was part of an IBM "Holiday Party" where dozens of IBMers met "in the virtual world" to participate in 3D competitions,I entered the "Build a Snowman" competition, since I am still a beginner at this. This was whatI was able to come up with in 20 minutes that we had to get it done. Why I made mine out of woodwith different colors was so that I could stand out from the crowd. Everyone else used traditionalwhite snowy textures.
Others had a more challenging "Build a Snow Globe" where you have to write scripts to get thelittle snow flakes to move around. This for the advanced builders of our group.
This is still new, emerging technology, but eventually, Second Life and other MMOs could be used to market products,that people can view from all three dimensions, talk to a technical specialist, and get all questions answered.It could be used for education, shopping around, and collaborating with others.
Anyways, I haven't heard the results, but I had fun anyways.

For those of us in the northern hemisphere, yesterday was this year's Winter Solstice
, representingthe shortest amount of daylight between sunrise and sunset. So today, I thought I would blog on my thoughtsof managing scarcity.
Earlier in my career, I had the pleasure to serve as "administrative assistant" to Nora Denzel for the week at a storage conference. My job was to make her look good at the conference, which if you know Nora, doesn't take much. Later, she left IBM to work at HP, and I gotto hear her speak at a conference, and the one thing that I remember most was her statement that thewhole point of "management" was to manage scarcity, as in not enough money in the budget,not enough people to implement change, or not enough resources to accomplish a task.(Nora, I have no idea where you are today, so if you are reading this, send me a note).
Of course, the flip-side to this is that resources that are in abundance are generallytaken for granted. Priorities are focused on what is most scarce. Let's examine some of theresources involved in an IT storage environment:
- Capacity - while everyone complains that they are "running out of space", the truth is that most external disk attached to Linux, UNIX, or Windows systems contain only 20-40% data. Many years ago, I visitedan insurance company to talk about a new product called IBM Tivoli Storage Manager. This company had 7TB of disk on their mainframe,and another 7TB of disk scattered on various UNIX and Windows machines. In the room were TWO storage admins for
the mainframe, and 45 storage admins for the distributed systems. My first question was "why so many people forthe mainframe, certainly one of you could manage all of it yourself, perhaps on Wednesday afternoons?" Their response was that they acted as eachother's backup, in case one goes on vacation for two weeks. My follow-up question to the rest of the audience was:"When was the last time you took two weeks vacation?" Mainframes fill their disk and tape storage comfortablyat over 80-90% full of data, primarily because they have a more mature, robust set of management software, likeDFSMS.
- Labor - by this I mean skilled labor able to manage storage for a corporation. Some companies I have visitedkeep their new-hires off production systems for the first two years, working only on test or development systemsonly until then. Of course, labor is more expensive in some countries than others. Last year, I was doing a whiteboard session on-site for a client in China, and the last dry-erase pen ran out of ink. I asked for another pen, and they instead sent someone to go re-fill it. I asked wouldn't it be cheaper just to buy another pen, and they said "No, labor is cheap, but ink is expensive." Despite this, China does complain that there is a shortage of askilled IT labor force, so if you are looking for a job, start learning Mandarin.
- Power and Cooling - Most data centers are located on raised floors, with large trunks of electrical power and hugeair conditioning systems to deal with all the heat generated from each machine. I have visited the data centers ofclients that are forced now to make decisions on storage based on power and cooling consumption, because the coststo upgrade their aging buildings are too high. Leading the charge is IBM, with technology advancements in chips, cards, and complete systems that use less power, and generate less heat. While energy is still fairly cheap in the grand scheme of things, fears ofGlobal Warmingand declining oil supplies, the costs ofpower and cooling have gotten some news lately. In 1956, Hubbert predicted US would reach peak oil supplies by1965-1970 (it happened in 1971), and this year Simmonsestimated that world-wide oil production began its decline already in 2005. Smart companies like Google have movedtheir server farms to places like Oregon in the Pacific Northwest for cheaper hydroelectric power.
- Bandwidth - Last year IBM introduced 4Gbps Fibre Channel and FICON SAN networking gear, along with the servers and storage needed to complete the solution. 4Gbps equates to about 400 MB/sec in data throughput. By comparison, iSCSI is typically run on 1Gbps Ethernet, but has so much overheads that you only get abour 80 MB/sec. Next year, we may see both 8 Gbps SAN, and 10 GbE iSCSI, to provide 800 MB/sec throughputs. My experience is that the SAN is not the bottleneck, instead people run out of bandwidth at the server or storage end first. They may not have a million dollars to buy the fastest IBM System p5 servers, or may not have enough host adapters at the storage system end.
- Floorspace - I end with floorspace because it reminds me that many "shortages" are temporary or artificially created. Floorspace is only in short supply because you don't want to knock down a wall, or build a new building, to handle your additional storage requirements.In 1997, Tihamer Toth-Fejel wrote an article for the National Space Society newsletter that estimated that ...Everybody on Earth could live comfortably in the USA on only 15% of our land area, with a population density between that of Chicago and San Francisco. Using agricultural yields attained widely now, the rest of the U.S. would be sufficient to grow enough food for everyone. The rest of the planet, 93.7% of it, would be completely empty.Of course, back in 1997 the world population was only 5.9 billion, and this year it is over 6.5 billion.
This last point brings me back to the concept of food, and I am not talking about doughnuts in the conference room, or pizza while making year-end storage upgrades. I'm talking aboutthe food you work so hard to provide for yourself and your family. The folks at Oxfam came up with a simpleanalogy. If 20 people sit down at your table, representing the world’s population:
- 3 would be served a gourmet, multi-course meal, while sitting at decorated table and a cushioned chair.
- 5 would eat rice and beans with a fork and sit on a simple cushion
- 12 would wait in line to receive a small portion of rice that they would eat with their hands while sitting on the floor.
So for those of you planning a special meal next Monday, be thankful you are one of the lucky three, and hopefulthat IBM will continue to lead the IT industry to help out the other seventeen.
Happy Winter Solstice!

'Those who cannot remember the past are condemned to repeat it.'
--- George Santayana
This last week of 2006 seems like a good time to recap the past year, and review the upcoming new year.That said, a good start is PC World's Top 21 Tech Screwups of 2006.
- Laptops made the news this year in a variety of ways. #1 was exploding batteries,and #6 were the stolen laptops that exposed private personal information. Someone I knowwas listed in one of these stolen databases, so this last one hits close to home. Securityis becoming a bigger issue now, and IBM was the first to deliver device-based encryptionwith the TS1120 enterprise tape drive.
- IBM makes the chips used in all the major game consoles: Microsoft's Xbox 360, Nintendo's Wii,and Sony's PlayStation 3. Being all based on IBM technology doesn'tmake the games interoperable or compatible, and in the case of Sony, it made #8 for being incompatible with their own PlayStation 2.Sadly, Nintendo's Wii had its own set of problems, and I found this parody of asafety video on YouTubeyou might enjoy.
- Microsoft had #5 (not understanding the holiday shopping season ends in December), #12 (not understanding people who use PCs prefer privacy), and #17 (not understanding how people useMP3 music players). At least they delivered their latest Xbox with minimal problems.As an engineer, taking on a market strategy role involved reading books and taking classeson marketing. I learned that it is all about understanding the marketplace well enoughso that your prospects "know, like, and trust" your company. Perhaps Microsoft should take a refresher course.
- A few companies showed off their brilliant customer service. Comcast is representedin a video on #7, and AOL in a taped phone conversation on #15. Many of our clients areafraid of vendor lock-in, and how difficult it might be to undo the deployment of new storagetechnology. Fortunately, IBM is committed to open standards, making it easier for our clientsto make the right choice and feel good about it.
Hopefully, we can all learn from the mistakes of others, and not repeat them in 2007.

In his blog, Paul Gillin agrees with Time Magazine's Person of the Year
choice of "all of us", those of us who use the World Wide Web to do business or have fun, and to those who contribute to the internet by creating content, such as people who blog or create websites.
So, in continuing my theme this week to recap the best and worst of last year, I list my personal "tech highlights" of 2006.
- Programming my Tivo Remotely.
Last September, I realized on a 3-week business trip that I had not programmed my Tivo to record the premieres of each of the new season's television shows. If you miss the first few weeks, it might be difficult to make sense of the rest of the season. Fortunately, I was able to program my Tivo remotely through the internet.
- Purchasing TV shows on iTunes
Despite this, I had a repeat episode of "House" record instead of a new episode of
"Heroes". By the time I realized this, the episode of was no longer available on NBC.com, but I was able to purchase it from iTunes for only $1.99, so that I could continue to enjoy the series.
- Using Wikipedia
Still unable to make sense of what was going on in the TV show "Heroes", I was able to read the "wiki" which explained all the subtle imagery and background implied.
- Using Linux to rescue lost Windows data
My disk drive failed on my laptop, and although I had most of my data backed up with Tivoli Storage Manager prior to my business trip, I had some files that I acquired or updated during the business trip. Thankfully, there are Linux "LiveCD" images that allow you to access your Windows files. You boot these LiveCD images from your CD drive, so there is no installation of Linux on the hard drive itself. If you travel as much as I do, consider bringing along some Linux CDs to get you out of trouble.
- Connecting my home entertainment system to my Mac
I now have an 802.1g (54Mb) wireless hub which allows my Tivo to connect wirelessly to the internet to get daily updates, but also allows me to play all my music stored on my Mac through my home entertainment system, and I can also listen to thousands of radio stations through "Live365.com". My favorite station is "Depeche Mode Inspired" which plays songs by Depeche Mode, as well as cover versions by a variety of others.
- Learning to Blog
Believe it or not, there is a right way and a wrong way to blog, and this year has been a good learning experience. IBM has a fairly healthy blogging policy, but nonetheless, say the wrong thing and I could be in serious trouble. Fortunately, that hasn't happened, and I am glad to see a fairly open exchange of ideas among the set of bloggers that discuss storage issues.
- Building a Snowman in Second Life
I have been a member of Second Life now since November, but it wasn't until I entered a competition to build avirtual snowman last week that the potential of this new interface became obvious to me. There is still lots to learn, but at least now I see value in spending more time and effort learning more about it.
- Getting an all-in-one printer/scanner to work with both my Mac and IBM PC
I didn't think it could be done, but here it is, my all-in-one Printer/Scanner works correctly, seemlessly, from both my Windows PC and my Mac Mini, and I have it on my home network so my laptop can use it also, wirelessly!
- Using Google Language Tools to translate materials to Portuguese
I speak several languages, enough to order food in restaurants and to get around through various modes of transportation, but translation for a technical audience is more challenging. A class we normally conduct in pure English was taken to Sao Paulo, Brazil, and although most students know some amount of English, we thought it would be good to translate the test questions to Brazillian Portuguese. I took the questions and ran them through a number of translation services websites, and had local IBMers review the results. The winner was Google language tools, which required hardly any edits to the generated text. The class was a big success.
- Digital Cameras and CD Burners
As I travelled from Brazil to Bolivia last August, I met a young back-packer who was on her way to Peru, but was staying in La Paz for a few days. We had a great time together, and I was able to transfer the digital photos from my Canon PowerShot digital camera into my laptop and burn her a CD to take with her to Peru.
- Painting my Dining Room table
After Halloween, I accidently left my pumpkin jack-o-lantern on my kitchen table as I left for a trip, and when I got back, it had decomposed and left a terrible stain on the wood surface. After sanding the table, I determined that the best course of action was just to paint the surface. I could have just painted it a solid color, or maybe a faux finish with two colors, but instead, chose to copy a famous painting, "Le Cafe" by Alberto Magnelli. I was able to scan this into my computer, resize it, and then project the image onto my table, to then outline the image and paint. I know I would not have been able to do this free-hand.
I am sure there are other triumphs I had throughout the year, but these are the first the come to mind.

Continuing this week's theme of recap for 2006, I thought it would be good to look back at the various videos made available on the internet.
- Of course, my favorite is Rebels with a Cause that covers the 50 years of IBM disk systems innovation.
- Twist Image has a recap of some of the videos that were sent around to everyone's email. In case you didn't get them all, here they are on one site. Of these, my favorite is "Ask a Ninja".
- If you are in Tech Support, or have ever dealt with Tech Support as an end-user, you might enjoy this video from Norway.
- John Edwards announces his candidacy for US President in 2008 on YouTube.
- IBM Worldwide VP of Sales Bob Hoey's three lessons for mainframe sales, which was discussed in an article by the Poughkeepsie Journal.
- Interview of Jamie Hewlett, co-creator of the Gorillaz animation.
It will be interesting what videos we get for 2007. Happy New Year everyone!

Happy New Year!
This year I resolve to be more consistent in my blogging, and my goal is to give you one to five entries per week, every week, based on the advice from Glenn Wolsey, Jennette Banks, and others.On some weeks, I will have a running theme, so rather than super-long entries to cover everything I can think of on a topic, make the entries short and readable. This week is a good time to review last year's "New Year's Resolutions" and to make new ones for 2007. I will discuss actions that companies can adopt for their data centers.
A common resolution is to lose weight, as in this Dilbert comic. Last year, I resolved to lose weight in 2006, and am delighted with myself that I lost eight pounds. When people ask for the secret of my success, I whisper in their ear "Eat less, exercise more." In general, people (and companies) know what to do, but just don't do it, which Pfeffer and Sutton document in their book The Knowing-Doing Gap. In my case, it involved lifestyle change: I exercised at a gym three times per week in Tucson, with a personal trainer, and revamped my diet.
Not everyone subscribes to the "eat less exercise more" philosophy. For example, Ric Watson argues in his blog that you can eat fewer calories, but eat more in actual volume, by choosing the right foods. This brings up the issues of "metrics" that most data centers are familiar with. Last year, I read the book "You: On a Diet" which explains that it is better to focus on "waist reduction" as measured in inches around your mid-section at the belly button, than "weight reduction" as measured in pounds. This year, I resolve to get down to 35 inches by the end of 2007.
The problem with measuring "weight" is that you are weighing bones, muscle and fat. A person can gain ten pounds of muscle, lose ten pounds of fat, and the scale would indicate no progress. The same problem occurs in data centers. How many TB of data do you have? Storage admins can easily tell you, but can they tell how much of this is bone (data needed for operating infrastructure), muscle (data used in daily operations that generates revenue) or fat (obsolete or orphaned data)?
We at IBM often state that "Information Lifecycle Management (ILM)" is more lifestyle change than a "fad diet". Figuring out what data you should capture in the first place, where to place it, when to move it, and when to get rid of it, is more important that just buying different tiers of storage hardware. So, for those looking to make new data center resolutions, I suggest the following actions:
- Re-evaluate the metrics you now use, and determine if they are helpful in making decisions and taking action.
- Come up with new ones that are more focused to solve the issues you face.
- Consider storage infrastructure software, such as IBM TotalStorage Productivity Center, to help you gather the information about your SAN, disk and tape systems, calculate the metrics, and automate the appropriate actions.
If you don't know where to start with ILM, certainly IBM can point you to the right solutions,best practices, techniques, and whitepaper.

Continuing this week's theme of New Year's Resolutions
for the data center, today we'll talk about one that many people make for their own personal lives: staying on a budget.
Often, when faced with a tightening budgets, we try to make more use of what we already have. Tell someone they are only using 10 percent of their brain, and they immediatelybelieve you; but tell them they are only using 30 percent of their storage, and they ask for a whitepaper,magazine article, or clarification on how that percentage is calculated. I actually visiteda customer that was only using6 percent of the storage attached to their Windows servers!
So, to help those of you making data center resolutions to stay on budget, the terms to remember are "Reduce", "Reuse" and "Recycle".
- When people come to request storage, are they being reasonable about what they need today, or are they asking for what they might need over the next three years? They might need 50GB, but they ask for 100GB, in case they grow, and a year later, you find they have only 15GB of data on it. On the flipside, the person asks for what they need but some storage admins give out more, just so they don't have to be bothered so often when growth happens. Finally, I have seen this formalized into fixed size LUNs, all the disk is carved into big huge 100GB pieces, so if you need 20GB, here's one big enough with plenty of room to grow.
If you are going to keep on a budget, remember that storage today is 30% more expensive than storage next year. That is the average drop in both disk and tape on a dollar-per-MB basis. If there is any way to postpone giving out storage until it is actually needed, you can save a bundle of money. Timing is everything! In the event of a disaster, getting immediate replacement for disk can be very expensive, but if you can wait just two weeks, you can negotiate a better deal. I thought of this while going to the movie theatre yesterday. A "hot dog" and a bottle of water was $8.00, but if you are able to wait two hours and eat after the movie, you can get a much better meal for less.
- A lot of companies buy new storage because their existing storage isn't fast enough, or doesn't have the latest copy services. This can easily be solved with an IBM SAN Volume Controller (SVC). The SVC can virtualize slower, functionless storage, and present to your application hosts virtual disks that are faster, and with all the latest disk-to-disk copy services like FlashCopy, Metro Mirror, and Global Mirror.
Chances are, you have unused disk capacity spread across all your storage today, but perhaps they are formatted into small LUNs. The SVC can combine the capacity, and let you carve up big LUNs at the sizes you need.This is like taking all those tiny pieces of soap in your shower and forming a new bar of soap, or taking all the crumbs at the bottom of your bread box, and making a new slice of bread. And, the virtual LUNs are dynamically expandable,so give out only the amount they need today, as it is simple to expand them to larger sizes later.
- Of my 13 patents, the first will always be my favorite, on a function called "RECYCLE" for the Data Facility Storage Management Subsystem Hierarchical Storage Manager (DFSMShsm) product, which is now a component of the IBM z/OS operating system. Basically, tapes could contain hundreds or thousands of files, such as backup versions or archive copies, and these expired on different dates. As a result, a tape would be written100 percent full, and then over time, decrease in valid data to 80, 60, 40, 20 until it hit 0 percent. In some cases, a single filecould hold an entire tape hostage. RECYCLE was able to read the valid data off tapes that were perhaps less than 20 percent full, and consolidate them onto fewer tapes. As a result, a whole bunch of tapes could be returned to the scratch pool, and reused immediately for other workloads. This also helps in moving to newer, higher capacity cartridges, such as the new 700GB cartridge that IBM co-developed with FujiFilm.(This RECYCLE function exists in our IBM Tivoli Storage Manager software, as well as our Virtual Tape Server, but is called "reclamation" instead, to avoid confusion on searches.)
When evaluating your use of tape, determine if you are making best use of the tapes you have now, and perhaps a RECYCLE (or reclamation) scheme may be in order. Fewer tapes can save money in many ways, such as reduced storage costs, and reduced courier costs to send the tapes offsite. Tape media can still be 10-20 times less expensive than disk, based on full capacity.

Wrapping up this week's theme of New Year's Resolutions for the data center, the New York Times argues we should go easy on the resolutions
, so I'll conclude with reducing stress. Lighten up! Relax, and try not to take your job so seriously.
(I know you're probably thinking, "That's easy for you to say, Mr. paid-to-play-golf-with-clients big-shot executive, but what about the rest of us?" or perhaps "I can't do that! My job is so important that if I didn't take it so seriously, my company would go bankrupt, my industry would falter, and global economies will collapse!" I can understand. Over 70 percent of all of the world's business transactions travels through, or sits on, IBM equipment, so you can imagine how stressful my past 20 years have been. Bear with me, read on, and hopefully you might benefit from my past experiences.)
- Laugh out loud
- Everytime someone laughs out loud at the office here in Tucson, everyone else within earshot stops what they are doing and rushes over to see what is so funny. Likewise, everytime it rains during normal working hours, people stop what they are doing, and run to the windows to see what water coming out of the sky looks like. Do you work in a "dry" climate, where laughter, like rain, is a rare occurrence?
Recognizing the benefits of laughter on reducing stress and improving health, my friends and I started theTucson Laughter Club back in 2004. There are hundreds of laughter clubs across the United States and the rest of the world, sometimes referred to as "Laughter Yoga" groups. Those of you readers in Tucson are welcome to join us, our next meeting is January 13.
Look to see if there is one near you, or start your own. Until then, laugh while you watch this funny storage-related video from the folks over at Sun StorageTek, or this one from Kodak.
- Every laughter club meeting starts out with some breathing exercises. If you feel stressed, try this simple2-minute relaxation technique.
- I'm not just talking about stretching our muscles here.
- The next time you tell the story, stretch the truth a little, aim for 70 percent truth, 30 percent embellishment.
- The next time you are making plans for lunch or dinner, stretch yourself out of your comfort zone and try something new and different, new restaurant, or different type of cuisine.
- The next time you get called by a phone solicitor or telemarket, stretch out the conversation, have fun with it, ask them what they are wearing, and share with them all the successes and problems you have at work, until THEY hang up first.
- The next time you are throwing a party, stretch your invite list to include someone you normally wouldn't invite, perhaps a neighbor or co-worker.
- The next time someone insists you make a list,stretch the process out, to give you more time to drink their expensive wine.
- When you hear the phrase Work/Life Balance, do you think to yourself, "I would settle for Work/Sleep Balance!"You're not alone. The National Sleep Foundation reports that most Americans don't get enough sleep, which can causevarious health problems.
So get plenty of sleep at home, before you get fired forsleeping on the job.
- Get along with others
- Peace on earth starts one relationship at a time.I found this amusing article on Wired, discussion the Top Blogfights of 2006.Can't we all get along? I stopped two blog-fights in 2006, just by pointing to the facts, and setting the record straight.
If there is someone you are not getting along with at work, fix it. Sooner, rather than later. Here are tips to be more assertive.
- Listen to Music
- Can you listen to music where you work? Listening to music has been shownto help reduce stress.I've got my Thinkpad T60 laptop connected to my wireless bluetooth headset, so I can listen to relaxing music without disturbing anyone else, and not be "tethered" to my system with traditional headphone wires.
In her book, "Life Hacker: 88 tech tricks to turbocharge your day", Gina Trapani suggestsPink noise. I prefer"The Quiet Earth", an internet radio station on Live365.
So, relax and enjoy your weekend. And remember, when you get back to the office on Monday, its only ones and zeros.

Continuing this week's theme of New Year's Resolutions for the data center, today we'll talk about one that people don't always think about on a personal level, that is to hone your tools and skills.
A long time ago, I used to be a regular speaker at the SHARE user group conference. One of the most attended sessions was Sam Golob presenting the latest CBT Tape set of tools. Over time, this large collection of "mainframe shareware" was handed out on 3480 tape cartridges, then on CDs, and finally made downloadable off the web.Sam's main point, which I remember to this day, was that everyone who has a job should figure out what tools they use, keep those tools functioning properly, and learn to use them well.
Later, I took some cooking classes at a culinary school. Among other things, we learned:
- A sharp knife is safer and easier to use than a dull one, resulting in fewer accidents
- Knowing what you are doing is the difference between food that is "simply awful" to that which is "awfully simple" to prepare.
- A well trained chef can prepare most meals with just a sharp knife and wooden spoon.
This last point hits close to home, as many people like me have too many tools that they do not use often enough to know how to use them well. Do I really need my strawberry corer, garlic press, or a tray designed for the storage and delivery of deviled eggs?
The same could be said about software tools. What tools do you use in your job? Do you feel you know how to take full advantage of their power and capabilities?If you develop software, do you know all the features for your debugging tools? If you develop advertising or marketing materials, do you know all the features of your photo or video editing software? If you manage storage in a data center, do you know all the tools for managing your storage area network (SAN), disk systems, tape libraries, and reporting tools to identify all of your files and databases across your entire IT environment?I would not be surprised if you could replace a whole mess of tools with just one, such as the IBM TotalStorage Productivity Center.
For me, I resolve to learn how to better use Lotus Notes e-mail client, and perhaps the new Office 2007.

Last week, Paul Weinberg of eChannelLine.com asks Is this the year of the SAN (again)?
So, I thought this week I would cover my thoughts and opinions on storage networking. We oftenfocus on servers or storage devices, and forget that the network in between is an entire worldon itself.
I believe Mr. Weinberg is basing this on the idea that in 2007, over 50 percent of disk will beattached over SAN, edging out the alternative: Direct Attached Storage (DAS). But perhaps 50 percentis the wrong number to focus on. In 2007, The United Nations estimates thatcities will surpass rural areas, with just over 50 percent of theworld's population. Does that make this the "Year of the City"? Of course not.
Instead, I prefer to use the methodology that Malcolm Gladwell uses in his book, The Tipping Point.(I have read this book and highly recommend it!)Gladwell indicates that the tipping point happens at the start of the epidemic, not when it is half over.Isn't it better to celebrate the sweet 16 debutante ball when young ladies have completed their years of training and preparation, and are ready to be introduced to the rest of the world, rather than after they are thirty-something, married with children.
Let's explore some of the history. Stuart Kendric has a nice 7-page summary on theHistory & Plumbing of SANs.
IBM announced the first SAN technology calledEnterprise Systems Connection (ESCON) way back in September 1990. This allowed multiplemainframe servers to connect to multiple storage systems over equipment called "ESCON Directors" that directedtraffic from point A to point B. Before this, mainframes sent "ChannelCommand Words" or CCWs, across parallel "bus and tag" copper cables. ESCON was serial overfiber optic wiring. SANs solved two problems: first, it reduced the "rat's nest" of cables between many serversand many storage systems, and second, it extended the distance between server and storage device.
For distributed systems running UNIX or Windows, the CCW-equivalent over parallel cables was called Small ComputerSystem Interface (SCSI). The SCSI command had over 1000 command words, so for its Advanced Technology (AT) personal computers (PC AT), IBM introduced a subset of SCSI commands called ATA (Advanced Technology Attachment). ATA drives supportedfewer commands, ran at slower speeds, and were manufactured with a less rigorous process. Today ATA drives are about 55 percent the cost per MB as comparable SCSI drives.
Anyone who has ever opened their PC and found flat ribbon cable with eight or sixteen wires in parallel, can understand that the same issues applied externally. Parallel technologies arelimited to distance and speed, as all the bits have to arrive at the end of the wire at approximately thesame time. Direct attach schemes with every server attaches directly to every storage device were also problematic.Imagine 100 servers connected to 100 storage devices, that would be 10,000 wires!
So, a new technology standard was developed, called Fibre Channel, ratified in 1994.The spelling of "Fibre" was intentionally made different than "Fiber" on purpose. "Fibre" is a protocol thatcan travel over copper or glass wires. "Fiber" represents the glass wiring itself.
Fibre Channel is amazingly versatile. For today's Linux, UNIX and Windows servers, it can carry SCSI commands, and the combination of SCSI over FC is called Fibre Channel Protocol (FCP). For the mainframe servers, it can carry CCW commands. Running CCW over Fibre Channel is called FICON. This convergence allows mainframes and distributed systems to share a common Fibre Channel network, using the same set of switches and directors.
We saw the use of SANs explode in the marketplace over the past 10 years, and then cool down with a series of mergers and acquisitions. Last year, Brocade announced it was acquiring rival McData, so we will be down to two major players, Cisco and Brocade.
So, IMHO, I think we are well past the "Year of the SAN".

Continuing this week's theme on Storage Area Networks, today I thought I would talkabout the various terms we use for our equipment.
One area of confusion are the adjectives "entry-level", "midrange" and "enterprise-class".What do these mean? Well, as in the case of disk and tape, these three are all relative terms that are a combination of "small, medium, large" as well as "good, better, best".
- Entry-level switches are typically only a maximum of 8-16 ports.Ports can connect the switch to a server, a storage device, or another switch.These are sometimes called "edge" switches, as they might be found in the mostremote sections of an office campus, remote branches, or other isolated areasoutside the primary data center.
- Midrange switches typically have a maximum of 32-64 ports.More ports on a single switch means fewer switches (and fewer cables) to manage.
- These are called "directors" to distinguish them from entry-level and midrange offerings.Directors have a maximum of 140-528 ports, and because so many devices or switches can beconnected to them, they need to be extremely reliable. Directors are designed for 24x7operation, with the ability to make most upgrades and configuration changes while the boxis running (often referred to as "non-disruptive upgrades"). Availability is typically better than "five nines", or 99.999 percent, which means that the box will be up 99.999 percent of the time, or conversely, will be down lessthan 5 minutes per year.
If you are asking yourself "which size is right for my company?" or "is my company big enoughfor a director?" you are asking the wrong questions! Instead, determine a SAN configurationthat meets your workload, and then decide the components for that design.
McData coined a phrase called "core/edge" design that is considered today as "Best Practice" throughout the industry.A good write-up can be found here at SearchStorage.com. Basically, you put your big beefy "core" directors in the center of the room, and then surround it with midrange switches, that then these connect to "edge" switches, that then connect to the servers and storage near them. As you grow, this design can easilyscale to grow with you.
So, if you need help implementing a SAN for the first time, or upgrading the one you have,call IBM, we can help!

Continuing on my theme of storage area networking, today I thought I would coverstorage networking at home.
Before the PC, corporate end-users had dumb terminals (displays) connected to mainframes (servers) thatwere then connected to external disk and tape (storage devices). This was all done with direct cable connections,then later through networks. The PC solved this by putting the display, server and storage into one unit, makingit more accessible to smaller businesses and individuals.
Many years ago, Microsoft started out with the vision "A PC on every desktop".The primary reason we even have networks is while everyone might have had their own PC, not everyone had their own printer. (Printers used to be part of IBM's storage division, which we explained as "storage on PAPER"!)Maybe if Microsoft's vision was "A PC and printer on every desktop", history might have turned up different.
Let's take a look at Apple's latest offerings shown at MacWorld 2007 in San Francisco, as well as how rivals battle for connected world at the Consumer Electronics Show (CES) 2007 in Las Vegas.Blogger Wax Banks argues that these announcements mean"the era of the personal computer is coming to an end".
Disclaimer: IBM has close business relationships with both Apple and Microsoft and others,providing the chips inside some of their products. I discuss them here not only becauseI am trying to get you to buy their products, and let IBM benefit indirectly from their success, but because they are newsworthy, and relevant to the topic at hand.
My take on all this...
- MacWorld 2007
- Apple CEO Steve Jobs presented the Apple TV. You can watch the MacWorld 2007 keynote presentation, orsee Zayne Humphrey's summary in a series of photos, or read Glenn Wolsey's take.
The "Apple TV" is not a TV at all, but rather a server, one that lets your television (your dumb terminal)access the video, audio and photos stored on your Mac or iPod (the storage device), all through a home network.(Sound familiar?)
Apple changed their name from "Apple Computer, Inc." to just "Apple, Inc." to signal a subtle but significant change,namely, that they want to be invited to next year's Consumer Electronics Show!Seeking Alpha offersNine Ways Apple Changed the Face of Consumer Electronics.Uber-blogger Steve Rubel weighs in on why the iPhone is a game changer, but the Apple TV is not.
- Consumer Electronics Show (CES) 2007
- Mr. Wargo, director of industry analysis at the Consumer Electronics Association, the organiser of CES, said: "One of the other major themes of this year is the services and content that feed the networked home."
Bill Gates from Microsoft gave the keynote, and this is probably his last appearance, as he is retiring in 2008,as we are reminded by thisfunny video, to move on to bigger, and better things. It is perhaps fitting that his retirement aligns with the end of the era for the PC.
Microsoft unveiled their Microsoft Windows Home Server, again a server that connects your television (dumb terminal) with your PC or Zune (storage device)all through your home network. (Sound familiar, again?)
Whereas Apple above pretty much shunned the gaming community, Microsoft embraced it with their internet-enabled Xbox360.Microsoft sold 10.4 million of these last year, which was 400 million more than they projected.
Our SAN technology partner Cisco wants to get in on this "home networking craze", as written about inInfoWorld andCnet.
the consumer electronics industry is taking clues from IBM's mainframe business. Not the first time this has happened, and probably not the last.
I already access photos and audio with my Tivo, from both my Mac AND my PC,so not much new here for me. Getting my home network connected was one of mytech highlights of 2006 and organizing my audio content was done withILM for my iPod.
Bypassing the PC, by being able to have your television, handheld or phone access data directly will greatlyincrease the demand for storage from businesses that provide information and content, and for storage networking technology in the home. It will be interesting how this all plays out in 2007.

Continuing on my theme of storage area networking, today I thought I would coverthe concept of convergence. This is the notion of disparate things that come together.
Convergence plays a big role in Apple's new iPhone.ExpatJane has a nicecollection of news articles.Gizmodo has a two part hands-on experience of the iPhone hereand here. Seth Godin opines that theiPhone is not for everyone.
I would fall into the "not for me" category, at least at this time. The iPhone is GSM-capable phone with the ability to store 4GB or 8GB of music, photos and video, and has incorporated a 2 megapixel camera. Currently, I have separate components:
- A cell phone that is GSM plus CDMA, with features like "speakerphone" which I use quite a lot, but NO camera.
- A 7 megapixel camera, also very small, with removable memory cards.
- A 60GB iPod, with music and photos. My model is older and doesn't handle videos.
Since I visit government agencies, research and development labs, and other places that don't allow cameras, I have to either chose a cell phone that does not have camera capability in it, or have a camera phone that I leave behind in the car or at the front desk. I have chosen to get cell phones with NO camera. So, NOT having a camera is a primary feature I look for, but this is getting harder and harder these days. I don't know if Apple plans to have a non-camera version of their iPhone, but that would be a deal-breaker for me.
I do carry a separate camera, and where it is permissible, use it separately. This is especially useful if you do a lot of whiteboard or flipchart presentations, and want to capture what you have written for later. (For a great example of how effectively whiteboards can be used, check out these videos from UPS.)A picture is worth a thousand words, and is easier to convey an idea with pictures, especially in countries that may not speak English. Last month, I got a 7 megapixel camera to replace my 5 megapixel. For my work, 2 megapixel as found in the iPhone is not detailed enough.
As for my iPod, I enjoy that I can carry 60GB of music and photos. When I go on vacations, I can bring my camera and iPod, and connect the two, transferring and viewing the pictures that I take. I can easily free up 5-10 GB of space on my iPod for photos in preparation for a trip, then replace that with music when I am back at home. I also use my iPod as a remote disk drive for my laptop on business trips. Again, the 4GB and 8GB may not be enough for what I need.
Printers were never converged into Personal Computers, but they did have their own convergence. I have a multi-function printer/scanner/fax machine. I used to have separate printer, scanner and fax machines, but now the technology is so inexpensive that it got all combined into one solution.
The same is happening for Storage Area Networking gear.
- Thanks to Fibre Channel, switches and directors can handle both SCSI commands (FCP) and CCW commands (FICON). This allows the mainframe and distrbuted systems to converge their traffic onto a single network, and is less expensive than trying to maintain one network for the mainframes, and another for the distributed platforms.
- On the SCSI side, there are now switches that let you have pluggable ports of different flavors. For example, you can have some ports be Fibre Channel to receive FCP, and other ports to be Ethernet to carry iSCSI. iSCSI is a protocol co-developed between IBM and Cisco to carry SCSI commands over Ethernet. Since most computers already have Ethernet "network interface cards" and most buildings are already wired with an Ethernet infrastructure, this provides a less expensive alternative to Fibre Channel.
- Routers, and combination Router/Switches, can send all the FCP/FICON/iSCSI traffic over various long distances to remote data centers, using either iFCP or FCIP protocols. This is a less expensive alternative to dropping your own private "dark fiber" between the two locations, which often involves negotiating access rights to dig trenches through other people's property.
Which brings me back to Apple's iPhone. One device can make calls, watch video, and download webpages all because the networks have converged into sending all data in "packets". The network just routes packets from one place to another. It doesn't care that a packet is a voice packet, a video packet or a webpage packet. It doesn't matter.
This convergence then lets the convenience of a handheld device serve as the conduit for doing business, potentially replacing the credit card.IBM helped Visa and Nokia join forces to use cell phones as wallets. According to the article...
"Users can pay for groceries and other purchases by swiping a phone over a reader that electronically communicates with a microchip on the phone. Phone owners confirm the purchase with the push of a button and the deal is complete.
The platform is the result of many years of trials around the world and will enable mobile contactless payments, remote payments, person-to-person payments, and mobile coupons."
Now that's convergence I can get excited about!

Today, in the US, is Martin Luther King day
. There is a good post about this by Seth Godin
.Dr. King had a vision for the future, and is most remembered by his speech that began: "I have a dream..."
IBM also has a vision for the future, and like Martin Luther King's speech, is startingto enable change. Last February 2006, IBM launched "Information on Demand", a visionthat involves bringing together our hardware, software, and services.
The impact has not gone unnoticed. Barron's featured IBM in an article titled "The New IBM".
I suspect bloggers helped get the word out. Here's a graph fromYahoo! Financeshowing the IBM stock price over the pastsix months. This blog started in September, when stock was in the low 80's, and now it is in thehigh 90's. I can't take all the credit, of course, as there are now over 3000 IBMers blogging, either inside thecompany, or externally to the rest of the world.
And the future continues to look bright.Greg over at IBMeye feels thatIBM stock poised for anotherstrong year.
If the analysts are right, 2007 is going to be a good year!

Today, January 16, IBM launches its latest disk system, the DS3000 series.
There are actually three products in the DS3000 series:
The DS3200 is a 2U high, 12 drive system that attaches to servers via 3Gbps Serial Attach (SAS) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are theDS3200 specifications.
The DS3400 is a 2U high, 12 drive system that attaches to servers via 4Gbps Fibre Channel (FC) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are the DS3400 specifications.
The EXP3000 is a 2U high, 12 drive expansion drawer. It was announced back in August 2006, but is part of theoverall DS3000 series. It can be used directly with servers, but is also designed to be attached to the back of the DS3200 or DS3400 to increase capacity.Here are the EXP3000 specifications.
With this announcement, IBM provides entry-level storage at the "less-than-$5000" price point, withsupport for intermix of 10K and 15K RPM drives, and scalable up to 14.4 TB capacity.This would be ideal storage for HP, Dell, IBM System x and BladeCenter servers.

Next week I am "briefing" a client on a variety of topics, everything from our overall strategy, to our DS4000 disk systems, LTO tape, the DR550, and storage virtualization. A lot to cover, and they only gave me 60 minutes!
The challenge is not gathering the material, as it is shrinking it down to cover all the key points into a fluid story. Which reminds me of a saying we have inside IBM: "Develop with prose, Market with poetry." When I was in development, I had to write some huge specifications. Now that I am in marketing, the fewer words the better. In looking to see if this saying was a modified version of a famous quote from someone else, I encountered this interesting quote below. John Windsor of YouBlog might argue this could apply to most marketing attempts just as easily as most poetry.
Most people ignore most poetry
most poetry ignores most people.

Roger over at Creative Think asks ifChip Heath is the Next Malcolm Gladwell?, relating to a book called "Made to Stick". I just started reading this book yesterday, but it starts out with how some stories are more memorable than others. Some just "stick" in your head, like songs, and others are quickly forgotten.
I tell a lot of stories, some stick, some don't. For example, I had read in a Barnes and Noble flyer a description of a book that interested me. I went to the store, but had forgotten to bring the flyer with me. When the person at the help desk offered to help me find it on their computer system, I realized that I could not remember the author, the title nor the publisher. The only thing I could remember was that it was a dark green book. It was actually a collection of short stories that were all 55 words in length, all winners of a 55-word story contest. She then took out the flyer itself, and we found it easily from there. She asked why I only remembered that it was green, and I told her: "Because I collect green books."
I am amazed that the writers could cram a setting, characters, plot and resolution into only 55 words, and then I saw Anecdote's post Let's Be Brief which talks about the latest 6-word story contest, inspired by Hemmingway’s shortest story, which was only six words long.
Now that's brief!

Wrapping up my week's theme of "diversity", with posts on a diverse set of topics,today I will suggest ways to spendyour time while you are walking 10,000 steps per day, as recommended by the authorsof the book "You: On a Diet"
(If you thought this was about the 10,000 steps it might take to implement a storage solution, you should switch over to IBM as your storage vendor. For example, the DS3200 and DS3400 can beimplemented in as little as SIX steps. That's pretty cool.)
Blogs like Lifehacker are an excellent resource for neat littletips and tricks to help you throughout your day, like how to use your iPod, cell phone or computer better, for example. These suggestions are based on the idea that you can walk your 10,000 steps with access to an iPod and cell phone.
- Learning a language
- ... or refreshing yourself on a language you might not have spoken in a while. In addition to formal audio-based lessons from Pimsleur, there are podcasts you can get for various languages. In preparation for my upcoming trip to Japan and China, I have been listening to JapanesePod101.com and ChinesePod.com which have quick lessons that complement the formal training.This Lifehacker postindicates there are similar ones for French, Spanish, Italian, and Brazillian Portuguese.
- Practicing your presentation
- Walking while practicing your 30-60 minute presentation would be good exercise.MicroPersuasion explains how to turn your iPod into the ultimate PowerPoint accessory, and this article in PlayListmag.com providesthe steps to get a PowerPoint presentation onto your iPod. I did this, and the slides are found underPhotos->Photo Library. The images are small, but heck, they are your charts and you should recognize themwell enough to remind yourself what to say on each slide.Also, I am able to record my practice sessions using MP3 Recorder and listen as I page through each slide. (In theory, you can use your iPod to present your slides to your audience, plugging the iPod directly into the laptop projector, instead of a laptop, using cables available at your local Apple store, and use the iPod controls as your forward/backward remote.)
- Working your To-Do list
- You can download your to-do list to your iPod. I use BackPackIt from 37 Signals. You can sign up for a free account, or upgrade to a paid account, and have anamazingly simple browser-based tool to develop your to-do lists, one for each project or aspect of your life. Oncedone, the list can be emailed to you as plain text. Enable your iPod as an "external disk drive" and copy this text file to your NOTES directory on the iPod drive. Voila! You can now read your to-do list! (I could also send it to my cell phone, using email@example.com, but I find the iPod easier to read and navigate)
Think of something to add? Send an email from your cell phone. With BackPackit, I can send an email that will directly add my text as a note or todo list item. On my phone, this is simply sending a text message to "500" with text like:
"firstname.lastname@example.org todo # buy bread".The hash mark (#) separates the subject line from the body of the email, and this is how Backpackit knows its a todo item or a note. If you pre-program the huge email address in advance on your phone, then it isn't as bad as it looks. It will be on your packpackit page the next time you log in.
Well, that's three suggestions. The next time you complain that there is no time to walk, you now have no excuse.

Shakespeare wrote "What's in a name? That which we call a rose by any other word would smell as sweet." This week my theme will be on names, naming convention, and how we access information on storage.
Take for example these two sentences:
The Bears beat New Orleans.
Chicago clobbered the Saints.
Though they appear very different, football fans who might have watched either or both of the two conference title games yesterday would quickly recognize that they refer to the same two teams and the same end-result.
I'll be traveling to Asia next week. While most people call me "Tony", my legal given name is "Anthony" which is what appears on my passport and other legal documents. Most English-speaking countries handle this fine, but it can be confusing in Japan or China, where "A. Pearson" doesn't match "T. Pearson".
In the US, our given and family names are referred to as our "first name" and our "last name", relating to their positional sequence. In Asia, family names come first, followed by their given names last. To help avoid confusion, we have started adopting the practice of putting the family name in ALL CAPITAL LETTERS, so I would "Tony PEARSON" while my colleague may be "WONG Francis".
In Japanese, "Mr. JONES" would be "Jones-san". However, Pearson-san is such a toungue-twister, that most just say "Tony-san" which is fine with me. I have been called "Mr. Tony" in a variety of countries, perfectly acceptable.
You can call me anything you like, just don't call me late for dinner.
On his blog post on preparation
, Seth Godin mentioned an appropriate Swedish saying:
There is no bad weather, just bad clothing.
Appropriate because it snowed here in Tucson, Arizona on Sunday evening, leaving many of us here figuring out how to drive through the stuff on Monday. In my entire lifetime, I have only witness snow down in the Tucson valley a handful of times. It got me thinking about coats, and the wonderful schemes for coat check rooms, as an analogy for data access. A lot of people ask me to compare and contrast one technology from another, say block-level virtualization from content-addressable storage, and so on, and I always try to find a good analogy to help explain things.
Let's start with the setting. It is snowing outside and people are wearing coats. When they come inside, they check their coats at a coat check room, a large room with rows and rows of racks with hangers. A coat check attendant takes your coat and puts it on a hanger, and gives you a ticket or other identifier that will allow you to retrieve your coat later. The ticket must have sufficient information to retrieve the coat quickly, rather than searching rows and rows of hangers for it.
- Block-based disk storage
You walk to the coat-check desk, tell the attendant to hang your coat on a specific hanger, say hanger number 387. When you come back, you ask for the coat on hanger 387. The coat-check attendant knows exactly where hanger 387 is, and is able to retrieve it quickly. Most disk systems use this approach, including IBM SAN Volume Controller and DS family of disk systems.
- Name-based disk storage
You walk to the coat-check desk, tell the person the name that you want to call your coat. An empty hanger is located, and a list of coat names, with their associated hanger number, is then kept. Upon return, you ask for your coat by name, and the coat-check attendant looks up the hanger number to match, and retrieves your coat. This is the scheme used by the IBM System Storage DR550, N series for NAS storage, and the IBM Healthcare and Life Sciences Grid Medical Archive Solution (GMAS).
- Content-addressable storage (CAS)
You walk to the coat-check desk and hand them your coat. The attendant weighs your coat, checks the brand, the size, the number of buttons and zippers, types it all in, and the computer spits out a "hash code" from 1 to 99999. An empty hanger is found, and the hash code is associated to the hanger number. Upon return, you provide the hash code you were given, and the coat-check attendant looks up the hanger number to match, and retrieves your coat.This is the scheme used for some non-erasable, non-rewriteable storage, such as the EMC Centera.
IBM invented hash codes in 1953 as a way to speed up searches. For example, if you want to look up a word in the dictionary, knowing the first letter of the word makes it much quicker, because you can thumb directly to that section. A hash code was intended to give a more even distribution, so that if a million words are stored in a "hash code dictionary" then you would calculate the hash code, then look up only that section of words associated with that specific hash code number.
A problem arises when you generate "hash codes" for storage. It is possible for two different pieces of data to resolve to the same hash code. When an application tries to write a piece of data, and it resolves to a hash code that already exists, that is called a collision. One response is to either compare the incoming data to the data that is already stored, confirm they are identical, but that can be time consuming. The other response is to just assume they are identical, and reject the secondary copy, a process often referred to as "de-duplication".
What's the chance of getting a collision for data that is really different? Let's take for example the famousBirthday paradox. Suppose the coat check room assigned the hanger based on your birthday (month and day). How may coats before you run the risk of having two people turn in coats with the same birthday? After only 23 people, the likelihood is 50%. At 60 people, it goes up to 99%.
For this reason, IBM does not offer content-addressable storage. For non-erasable, non-rewriteable storage, the IBM System Storage DR550 requires the application to give each object a name, and that name is then used to storage the data, eliminating the possibility that data might accidently be thrown away.
It's safer that way.

Continuing my theme on naming conventions, this time I will talk about finding information.
Industry analysts estimate that information workers spend as much as 30 percent of their working day just looking for information they need, as mentioned in an interview withJeff Teper, Microsoft.A second study of middle managers found similar results, and is discussed in Information Architecture andDM Review.
Take for example looking for information on a specific person. If you were searching for"Barack Obama" or "Lulit Shiferaw", then perhaps you will find exactly the person you werelooking for.
On the other hand, some names are more common. I've met my share of people named John Smith, Jennifer Jones,or Mark Johnson. While PEARSON does not even make the top 100 list of family names here in the US, it isstill fairly common.
People looking for me may realize that I am notHead of Australian Economics at ANZ Bank, author of the book "Don't Read This!", winner of the Killam Teaching Prize, or owner offisheries in Essex.While I do work out at the gym on a regular basis, I look nothing like thisfamous body builder. There are several others, but I pickedjust a few to make my point.
At this time, there is only one "Tony Pearson" working at IBM. A while back, there was a second,a woman who spelled her name "Toni" with an "i" at the end. Her job involved deploying storage on AIX platforms,and was similar enough job description to mine that we would get each other's mail, and sometimes not realize it was meant for the other.
Dan Santow of Word Wise talks about the difficulties of proper names withaccent marks.This would make searching worse, but many search tools can handle this, stripping off allaccent marks to make the comparisons.
But what if you wanted to leave those accent marks in, for an exact match?

Stephen Colbert, of The Colbert Report
, explains the name changes in recent mergers
of the Telecommunications industry. A discussion on "changing names" and how that impacts storage seems like a good way to wrap up the week's theme on naming conventions.
Name changes are sometimes painful, but often times done for a purpose, such as to promote a family. In the US, when a man and woman marries, the woman often changes her family name to match her husband, and the kids all adopt the father's family name. I say "often" because there are times where the woman keeps her name, or adds to it in a hyphenated way. ABC News reported that a Man Fights to Take Wife's Name in Marriage. KipEsquire, a lawyer, writes about it in his blogA stitch in haste.
IT industry changes the names of products that people knew as something else. Other times, they re-use an existing name, when really it is or should be different from the original. Last year, I took on the job of helping transition from our brand "TotalStorage" to the "System Storage" product line under the new "IBM Systems" brand. I help decide what stays the same name or what changes, when it should change, and how to announce that change.
On the disk side, IBM renamed Fibre Array Storage Technology, or FAStT, which was pronounced exactly like "fast", to DS4000 series. This was a big improvement, as people couldn't seem to spell it properly, with variations like "FastT". Nor could people pronounce it properly, saying "fast-tee" instead. The advantage of "DS" is that it is both easy to spell, and easy to pronounce. The DS4000 series continues to be "fast", providing excellent performance for its midrange price category.
IBM's Enterprise Storage Server (ESS) line went from model E10, to F20, to 750 and 800. When IBM came out with its replacement, the IBM TotalStorage DS8000, some people asked why it wasn't named the ESS 900, for example. The DS8000 is quite different internally, new hardware design and implementation, but is highly compatible with the ESS line, and shares much of the same functionality from microcode. Last year, it was replaced by the IBM System Storage DS8000 Turbo. Again, newer hardware, so it was easy to justify the new name change from "TotalStorage" to "System Storage".
Renaming a product risks losing its certifications and awards. For example, IBM spent a lot of time and money getting the OS/390 operating system certified as a "UNIX" platform. When it was renamed to z/OS, IBM had to do it all over again. Learning from this experience, IBM decided not to rename the SAN Volume Controllerto a new designation like "DS5750", as it enjoys the "number one" spot on both the SPC-1 and SPC-2 performance benchmarks, and is recognized as the leader in the disk storage virtualization marketplace. Renaming this product would mean losing that collateral.
IBM's "other disk systems" the N series posed another set of challenges. The current DS line already has entry-level (DS3000), midrange (DS4000) and enterprise-class (DS6000 and DS8000) products. The OEM agreement that IBM has with Network Appliance (NetApp) resulted in a new set of entry-level, midrange, and enterprise-class products. But these didn't fit nicely into the DS3000-to-DS8000 continuum. Instead, IBM decided to go with N series, using N3000 for entry-level, N5000 for midrange, and N7000 for enterprise-class. These are different than the numbers used by NetApp for their comparable, but not identical, offerings.
On the tape side, IBM decided to name the tape drives TS1000 and TS2000 range, tape libraries and automation with a TS3000 range, and tape virtualization to the TS7000 range. A lot of tape products already had 3000 numbering that had to change to fit this new scheme. This is why IBM's popular 3592 tape drive was renamed to the TS1120. The replacement to the 3494 Virtual Tape Server was named TS7700 Virtualization Engine.
Obviously, you can't change the names of products that are currently in the field, but what about existing software with minor updates? IBM decided to leave "TotalStorage Produtivity Center" under the "TotalStorage" brand until it has a significant version upgrade. Many people say "TPC" as a convenient acronym when referring to this product, but TPC is a registered trademark of the Professional Golfers Association (PGA) to refer to its "Tournament Players Club".
How can anyone confuse "managing storage" with "playing golf"? One activity is full of frustration that takes years or decades to master, involving the need to understand a variety of equipment and techniques to use each properly to accomplish your goals; and the other is an enjoyable activity, immediately productive in front of a single pane of glass managing all of your DAS, SAN and NAS storage, from reporting on your files and databases to managing storage networks and tape libraries.
Enjoy the weekend!

This week I am in Japan, so my week's theme will center around travel, speaking at conferences, and Japan itself. I first travelled to Japan in the late 1980s, to visit a college friend who was working for Ford Motor Company, on assignment in Japan as liasion to Mazda Corp.
Back then, the only Japanese phrase I knew was "Wakarimashta" which means "I know" or "I understand". If you only know one phrase in a foreign language, this possibly could be the worst to know.
My second trip, I was better prepared. I learned three "survival phrases":
sumimasen - "I'm sorry/excuse me"
hanashimasen - "I don't speak"
wakarimasen - "I don't know / I don't understand"
These are great phrases to know individually, but even more powerful strung all together, to emphasize that you will begin speaking English, but at least with good reason (and perhaps a bit of irony.)
I've been to Japan many times since, and have picked up more of the language. When travelling to Japan, or anywhere for that matter, it is important to "pack light". I'll be gone for two weeks, but all I bring is a laptop bag and one carry-on piece of luggage.
I went on a trip to Prague (Czech Republic) with a female co-worker who brought FOUR pieces of luggage. One was just for shoes. Another piece was just for hair styling gel, make-up, face creams and finger nail polish. Today, the rules are different, and the TSA allows only a single quart-size plastic bag containing little jars of 3 ounces or less of liquids or gels. I didn't have any "quart-size" bags, so I used a smaller sandwich-size bag.
What does all this have to do with storage? I've helped many clients move data centers, and this involves moving their servers, their networks, and their storage. Servers and Networks are easy to move, but storage presents some challenges. In many cases, the entire company is shut down, the storage is moved, and then the company is operational again. Needless to say, it is best to do this over a weekend.
I tell clients to "pack light" and figure out what data they really need in the move. What do you really need to operate your business? Bring just that, the rest can arrive later.
This same concept applies for Business Continuity and Disaster Recovery planning. What do you really need after a disaster occurs? Can you run your business for a few weeks on that data, until the rest of the data is restored? If you can't run your entire business on that data, can you run your most important parts of your business?
If you run a bank, perhaps keeping your ATM cash machines running is more important than making out new loans. In Japan, if a bank has any outages that impact their ATM machines, they put out a full page advertisement in the local papers to apologize for the inconvenience.
Business Continuity is one of the nine "Infrastructure Solutions" that IBM can help clients with. If you are interested in learning more on how IBM can help you with your Business Continuity, click here.

Continuing my week's theme on travel, conferences, and Japan, I provide three more"survival words" in Japanese language. These might seem like an odd trio, but they comein very handy.
- Domo -- "very much"
- This is short for "Domo Arigato" which is "Thank you very much". If you just say "Domo"they assume you mean the full phrase, and gets the same point across. Some of my older readersmay remember a song by Styx "Domo Arigato Mr. Roboto" which is perhaps the only song I could think ofthat mentions IBM and Japan in the same song.
You're wondering who I am-machine or mannequin
With parts made in Japan, I am the modern man
I've got a secret I've been hiding under my skin
My heart is human, my blood is boiling, my brain I.B.M.
- Doko -- "where?"
- This word is great for trying to find places or things, such as "Where is the restroom?"Sometimes making an attempt to speak a country's official language will garner some respectand appreciation from the locals. If you're lost, and looking for help finding something, this is a great time to be appreciated.
Upon arrival to Narita, I was planning to take the N'EX high-speed train into town, but there was a train accident on the JR line, so I ended up taking the Kisei train over to Nappori station,then transfer over to a different line. Not what I had planned, but an adventure nonetheless.
- Dozo -- "after you" or "go ahead"
- Japan is all about showing respect to your elders, upper management, and others in great esteem or authority. When arriving to a dinner table, or leaving the elevator, this phraselets them know you are respectful by letting them go first. Americans always seem rushed,so it is good to show I can be patient also.

Continuing my week's theme on travel, conferences, and Japan, I saw two items in the newsthat seem to follow a common theme.
- According to the "The Daily Yomiuri", a local Japanese paper, "double happy weddings" arebecoming more and more popular in Japan. These would be called "stotgun" weddings in the US, butin Japan, couples pay extra to have a wedding between the fifth and seventh month ofpregnancy. As Dave Barry would say, I am not making this up. 27% of couples in Japan got married while or after pregnant. The logic is that they can celebrate both events with one ceremony. Many couples believe that the primary purpose of marriage is to have children, and somethat fail to have children suffer terrible anguish or divorce. Waiting untilbeing pregnant helps ensure the couple will be "successful" in this regard.
- IBM acquires Softek, a software company that develops a product called Transparent Data MoverFacility (TDMF) to move mainframe data from one disk system to another, while applicationsare running. This can be used, for example, to move data from outdated disk systems to IBMdisk systems. This is not to be confused with IBM's archive and retention software partner,Princeton Softech.
Softek is the software spin-off of Fujitsu (a Japanese computer hardware manufacturer). Fora while, Fujitsu made IBM-compatible mainframe servers, but was not successful at developingits own system software, relying heavily on IBM for this. Unable to compete against IBM, it stoppedmaking mainframe servers, but continues making other kinds of hardware equipment.
With TDMF, the process of moving data is simple. The software runs on z/OS and intercepts all writes intendedfor a source volumes on the old array, and re-directs a copy to destination volumes on the new device.Systems can run with old and new equipment side by side for a few weeks, with the new devicestaying in-sync with the old. When the client is ready to cross over, the systems arepointed to the new disk, and the old disk systems are detached and removed from the sysplex.
Afraid that installing TDMF will mess with your applications? IBM Global Technology Services (GTS)is able to roll-in a separate mainframe, move the data, than disconnect it along with the old storage.
(For customers running Linux, UNIX or Windows on other platforms, IBM offers SAN Volume Controller (SVC).While SVC is not marketed as a "data migration device", per se, it does have this capability.Many clients were able to cost-justify purchase of an SVCto move data from old storage to new in similar fashion to how TDMF works on the mainframe.)
What do these stories have to do with one another, other than both relating to Japan? IBM has beenusing TDMF for years as part of a service offering to move data from one disk system to another.Since Sam Palmiasano took over in 2002, IBM has acquired 51 companies, 31 of them software companies.Often, these have been "successful" turning quickly profitable because IBM was already well familiar with the companies they acquire, in much the same way that husbandsare well familiar with their brides-to-be at a "double happy wedding".
So, welcome Softek! It looks like its time to celebrate again!

Continuing my week's theme on travel, conferences, and Japan, I will discuss translation and interpretation.
By now, you realize that I speak some Japanese, but not enough to give a full presentation. In addition to English, I can present Spanish and Brazilian Portuguese, but am not yet comfortable doing a full hour talk in Japanese, especially when technical terminology is required.
This brings us to the differences between translation and interpretation. The former is more literal, but the latter is needed to get the spirit or essence of what is being communicated. Sometimes, the differences in languages and culture need to be taken into account to get the right meaning across.
- One phrase, different interpretation
The conference attire was listed as "Business Casual" which they use the foreign words, as it is a very foreign concept to the Japanese. In the US, Business Casual could be polo shirt and kahki pants, perhaps. In Japan, where everyone wears a dark suit, white shirt and conservative tie, "business casual" means your shirt can be blue, or have stripes. Few dressed down for the occasion; I saw mostly white shirts underneath those dark suit coats.
- One interpretation, different connotations
Working with my interpreter team, I went page by page to explain what I would say. On one page, I mentioned having "free space" to run applications. They asked if "free space" was good or bad? I was caught off-guard by this question. Americans enjoy wide open spaces, and the comforts afforded by having enough "leg room", "head room" or "elbow room".The Japanese word for this is "yoyu", which roughly translates to "leeway". However, "yoyu" also is used in the negative sense, tailored-to-fit clothing, for example, is preferred over loose-fitting off-the-rack clothing, because it has no "yoyu". Having too much "free space" can be just as bad as not enough, much like an hour presentation that ends 20 minutes too early is just as bad as one that goes 20 minutes over.
- One word, two different interpretations
In explaining the word "archive" we came up with two separate Japanese words. One was "katazukeru", and the other was "shimau".If you are clearing the dinner plates from the table after your meal, for example, it could be done for two reasons.Both words mean "to put away", but the motivation that drives this activity changes the word usage. The first reason, katazukeru, is because the table is important, you need the table to be empty or less cluttered to use it for something else, perhaps play some card game, work on arts and craft, or pay your bills. The second reason, shimau, is because the plates are important, perhaps they are your best tableware, used only for holidays or special occasions only, and you don't want to risk having them broken. As it turns out, IBM supports both senses of the word archive. We offer "space management" when the space on the table, (or disk or database), is more important, so older low-access data can be moved off to less expensive disk or tape. We also offer "data retention" where the data itself is valuable, and must be kept on WORM or non-erasable, non-rewriteable storage to meet business or government regulatory compliance.
- Sames words, different order
On many of my charts, we show on the left the entry-level models, in the center the midrange offerings, and on the right the enterprise class high-end devices. In English, I would say "Small, Medium, and Large". However, in Japan, they read from right to left, and their words "Dai, Chu, Sho" represent "Large, Medium, Small". So, the chart had the offerings on the page correctly sequenced, I just had to start on the right, and work my way to the left, from largest to smallest.
Understanding the differences in both language and culture greatly helps in communications.

I will wrap up this week's theme on travel, conferences and Japan discussingGroundhog day
, celebratedtoday (Feb. 2) in the US.
I thought of this because there was a 2003 movie called"Lost in Translation", the title of yesterday's post. This movie is about an American actor, played by Bill Murray, coming to Tokyoto film a whisky commercial. I first saw it with my sister and father, and we musthave been the only three who have actually been to Japan, as we were laughing hysterically,while the rest of the audience was utterly confused. If you have never been to Japan, see the movie before you go, then see it again after you get back home.
Ten years earlier, Bill Murray also played the lead role in another movie called"Groundhog day".In the movie, Bill Murray's character is TV newsman "Phil Connors" who travels to a small townwhere they bring out a small groundhog. If the groundhog can see his shadow, it predictsat least six more weeks of winter. If it does not, winter will end sooner. The nextday, Phil wakes up to realize that he is re-living the same day, over and over, like a modern-day Sisyphus or Promethius. Howhe handles himself in this situation, is what makes the movie so memorable.
When I explain what I do for IBM, to people I meet at home and abroad, I get asked the same set of questions.
- Don't you get bored presenting the same presentations?
The fact is, I never give the same presentation twice. Since I focus mostly on visual informationand what I say, versus the words of text on the page, I am able to customize my presentation toeach unique audience. In much the same way that Bill Murray's character managed to do somethingfun and different each day in the movie, despite his situation.
I do pity those presenters who focus entirely on text, turning their back to the audience, and then reading verbatim what is on each page.They should read Seth Godin's Really Bad PowerPointwith advice like "Bullets are for the NRA".
Another problem are presenters who apologize because they did not develop the materials they are presenting. Sorry, bub, you present it, you own it. The only person held accountable fora bad presentation at a conference is the speaker. When I make charts for others, I expect themthem to adjust it to their own speaking styles.
As a speaker, if you inherit materials fromsomeone else, have the courage to change it, or accept the parts you can't change, and have thewisdom to know the difference.
- Don't you get tired of traveling?
At first I thought this was odd. It's like asking "Don't you get tired of doing different things and eating different foodswith different people in a different country every week?" How can anyone grow tired of variety?
As with any question, you have to go inside the mind of the person asking the question.For most people, travel is an ordeal, outside their comfort zone. They are travelingto attend a funeral, family reunion, or a theme park with spouse and kids in tow.If that is the only kind of traveling a person knows, then it is understandablewhy they might ask this question.
- Don't you get annoyed answering the same questions at conferences?
As if this only happens at conferences!
Seriously, it might be the 17th time I've heard the question asked, but might be onlythe first time the person is asking it, and my response may be the crucial "first impression"that sets the stage for later engagements.
In this case, I focus on continuous improvement. What is the best way to answer thisquestion? How could I have answered that better? How could I have phrased the answerso it will be well-remembered? Again, like Bill Murray's character in "Groundhog Day",have fun with it, take advantage of the opportunity for improvement.
Enjoy the weekend!

Well, I have left Japan, and while everyone else is enjoying the Super Bowl, I am now in Australia, at another conference.Today I had the pleasure to hear filmmakers talk about their successes, and how IBM helps the movie industry.
- Khoa Do
At one extreme was Khoa Do, independent filmmaker. After acting in movies asideMichael Caine and Billy Zane, he decided to become his own director. He started a project to help seven disadvantaged youths from a poor drug-ridden section of Sydney, by having them act in his first full-length film.Armed with only an IBM laptop and small budget, he made the film called "The Finished People" that had critical acclaim.
The film was a success, and many of the disadvantaged youths have gone on to act in other movies. In 2005, Khoa Do was named "Young Australian of the Year".
Thanks to IBM technology, filmmaking is now accessible to a wider number of aspiring wanna-be directors. It is no longer necessary to be part of a large film studio with a multi-million dollar budget to tell your story.
- Xavier Desdoigts
At the other extreme, was Xavier Desdoigts, director of technical operations at Animal Logic, the Computer Graphics (CG) arthouse that produced special effects of movies like "The Matrix", "House of Flying Dragons" and "World Trade Center". They started with producing digital effects for TV commercials, like this one forCarlton Draught Beer.
With the support of a large film studio and multi-million dollar budget, Animal Logic now boasts the 86th most powerful "Supercomputer" based on IBM BladeCenter technology, with over 4000 servers connected into a cluster, for making the movie "Happy Feet". The movie took four years to make, with over 500 people, of 27 different nationalities. It was the first CG movie made in Australia, and has been well-received by audiences worldwide.
Mr. Desdoigts gave out some interesting facts and figures about the movie:
- While visually stunning on the big screen, each frame is only 1.4 Megapixel, about the same resolution as most camera phones.
- In one scene, there are 427,086 penguins all appearing on frame.
- Mumble, the lovable lead character, is made up of over 6 million feathers.
- As many as 17 dancers were "motion-captured" to choreograph the tap-dancing and character interaction segments.
- Only one system admin was needed to manage this entire server farm. (IBM Systems Director technology makes this possible)
- The movie consumed 103 TB of disk space, backed up to 595 LTO tape cartridges.
- An estimated 17 million CPU-hours were needed for all the processing and rendering.
Rather than talking about technology for technology sake, these filmmakers showed how technology couldbe put to use, in a practical sense, to provide the world something of value.

It's official! IBM System Storage TS1120 tape drive takes home the gold award, the product of the year, announced by Storage magazine.
I spent 18 hours traveling from Australia to China yesterday, and we were partially delayed due to weather, but felt that it was necessary to discuss the innovative use of encryption on this drive.
While most consider the TS1120 an "Enterprise-class" tape technology for the mainframe, it is also attachable to the smallest distributed systems running Windows, Linux, or various flavors of UNIX. Rather than limit users with an Encryption Key Manager that only ran on z/OS, IBM instead chose to implement it in Java, that can be run on anything from z/OS to Linux, Unix and Windows platforms, giving clients choice and flexibility in their deployment.
The design is quite clever and elegant. In the encryption world, there are two ways to encrypt.
- Symmetric Key
This is very fast, because it uses a single key for both encryption and decryption, and can be incorporated on a chip. The problem is that anyone with the key can read the sensitive data.
- Asymmetric Key
This is slower, but more secure, using two separate keys. The public "encryption" key takes clear data and encrypts it. Anyone can be freely given this key, as they cannot use it to decrypt any other data. The private "decryption" key is able to decrypt the data, so that one is kept secret. If two business plan to exchange lots of tapes, they can exchange their "encryption" keys to each other.
So, let's say that Green, Inc. wants to send a tape to Blue, Co. Blue has already provided its public "encryption" key to Green, so Green does the following:
- Generate a unique data key, will call it the "red key", and there is one for each tape. It is a standard AES 256-bit symmetric key that can be processed with less than one percent overhead on the tape drive. All the data is encrypted with this key.
- Store the red key on the tape. How does Green give Blue the red key? Green encrypts it with Blue's RSA 2048-bit public "encryption" key. This is stored on three places on the tape cartridge, one in memory, and the other two on the media itself.
- Sends the tape over to Blue Co.
When it arrives on the dock at Blue Co., they do the following:
- Mount the tape and decrypt the "red key" using Blue's super-secret private decryption key.
- Pass the "red key" to the tape drive, and have it read, append or re-write the tape.
If the super-secret private key is ever compromised, all you have to do is mount the tape, unlock the red key with the old private key, and re-lock the red key with a new public key. Since the red key doesn't change, the rest of the data can be left in tact. The whole process takes less than 5 minutes, compared to Sun Microsystems method, which could take 1-2 hours per cartridge, having to decrypt and re-encrypt the entire data stream.

In Storage Technology News, Marc Staimer makes hisSeven network storage predictions for 2007
. Let's take a closer look at each one.
- Federal Rules for Civil Procedures (FRCP) will increase adoption of unstructured data classification, email archive systems and CAS.
CAS continues to flounder, but the rest I can agree with. Regulations are being adopted world wide. Japan has its own Sarbanes-Oxley (SOX) style legislation go into effect in 2008.IBM TotalStorage Productivity Center for Data is a great tool to help classify unstructured file systems. IBM CommonStore for email supports both Microsoft Exchange and Lotus Domino, and can be connected to IBM System Storage DR550 for compliance storage.
- Unified storage systems (combined file and block storage target systems) will become increasingly attractive in 2007, because of their ease of use and simplicity.
I agree with this one also. Our sales of IBM N series in 2006 was great, and looking to continue its strong growth in 2007. The IBM N series brings together FCP, iSCSI and NAS protocols into one disk system. With the SnapLock(tm) feature, N series can store both re-writable data, as well as non-erasable, non-rewriteable data, on the same box. Combine the N series gateway on the front-end with SAN Volume Controller on the back-end, and you have an even more powerful combination.
- Distributed ROBO backup to disk will emerge as the fastest growing data protection solution in 2007.
IDC had a similar prediction for 2006. ROBO refers to "Remote Office/Branch Office", and so ROBO backup deals with how to back up data that is out in the various remote locations. Do you back it up locally? or send it to a central location?Fortunately, IBM Tivoli Storage Manager (TSM) supports both ways, and IBM has introduced small disk and tape drives and auto-loaders that can be used in smaller environments like this. I don't know whether "backup to disk" will be the fastest growing, but I certainly agree that a variety of ROBO-related issues will be of interest this year.
- 2007 will be remembered as the year iSCSI SAN took off because of the much reduced pricing for 10 Gbit iSCSI and the continued deployment of 10 Gbit iSCSI targets.
While I agree that iSCSI is important, I can't say 2007 will be remembered for anything.We have terrible memory in these things. Ask someone what year did Personal Computers (PC) take off, and they will tell you about Apple's famous 1984 commercial. Ask someone when the Internet took off, cell phones took off, etc, and I suspect most will provide widely different answers, but most likely based on their own experience.
For the longest time, I resisted getting a cell phone. I had a roll of quarters in my car, and when I needed to make a call, I stopped at the nearby pay-phone, and made the call. In 1998, pay phones disappeared. You can't find them anymore. That was the year of the cell phones took off, at least for me.
Back to iSCSI, now that you can intermix iSCSI and SAN on the same infrastructure, either through intelligent multi-protocol switches available from your local IBM rep, or through an N series gateway, you can bring iSCSI technology in slowly and gradually. Low-cost copper wiring for 10 Gbps Ethernet makes all this very practical.
Another up-and-coming technology is AoE, or ATA-over-Ethernet. Same idea as iSCSI, but taken down to the ATA level.
- CDP will emerge as an important feature on comprehensive data protection products instead of a separate managed product.
Here, CDP stands for Continuous Data Protection. While normal backups work like a point-and-shoot camera, taking a picture of the data once every midnight for example. CDP can record all the little changes like a video camera, with the option to rewind or fast-forward to a specific point in the day. IBM Tivoli CDP for Files, for example, is an excellent complement to IBM Tivoli Storage Manager.
The technology is not really new, as it has been implemented as "logs" or "journals" on databases like DB2 and Oracle, as well as business applications like SAP R/3.
The prediction here, however, relates to packaging. Will vendors "package" CDP into existing backup products, possibly as a separately priced feature, or will they leave it as a separate product that perhaps, like in IBM's case, already is well integrated.
- The VTL market growth will continue at a much reduced rate as backup products provide equivalent features directly to disk. Deduplication will extend the VTL market temporarily in 2007.
VTL here refers to Virtual Tape Library, such as IBM TS7700 or TS7510 Virtualization Engine. IBM introduced the first one in 1997, the IBM 3494 Virtual Tape Server, and we have remained number one in marketshare for virtual tape ever since. I find it amusing that people are now just looking at VTL technology to help with their Disk-to-Disk-to-Tape (D2D2T) efforts, when IBM Tivoli Storage Manager has already had the capability to backup to disk, then move to tape, since 1993.
As for deduplication, if you need the end-target box to deduplicate your backups, then perhaps you should investigatewhy you are doing this in the first place? People take full-volume backups, and keep to many copies of it, when a more sophisticated backup software like Tivoli Storage Manager can implement backup policies to avoid this with a progressive backup scheme. Or maybe you need to investigate why you store multiple copies of the same data on disk, perhaps NAS or a clustered file system like IBM General Parallel File System (GPFS) could provide you a single copy accessible to many servers instead.
The reason you don't see deduplication on the mainframe, is that DFSMS for z/OS already allows multiple servers to share a single instance of data, and has been doing so since the early 1980s. I often joke with clients at the Tucson Executive Briefing Center that you can run a business with a million data sets on the mainframe, but that there wereprobably a million files on just the laptops in the room, but few would attempt to run their business that way.
- Optical storage that looks, feels and acts like NAS and puts archive data online, will make dramatic inroads in 2007.
Marc says he's going out on a limb here, and that's good to make at least one risky prediction. IBM used to have anoptical library emulate disk, called the IBM 3995. Lack of interest and advancement in technology encouraged IBM to withdraw it. A small backlash ensued, so IBM now offers the IBM 3996 for the System p and System i clients that really, really want optical.
As for optical making data available "online", it takes about 20 seconds to load an optical cartridge, so I would consider this more "nearline" than online. Tape is still in the 40-60 second range to load and position to data, so optical is still at an advantage.
Optical eliminates the "hassles of tape"? Tape data is good for 20 years, and optical for 100 years, but nobody keeps drives around that long anyways. In general, our clients change drives every 6-8 years, and migrate the data from old to new. This is only a hassle if you didn't plan for this inevitable movement. IBM Tivoli Storage Manager, IBM System Storage Archive Manager, and the IBM System Storage DR550 all make this migration very simple and easy, and can do it with either optical or tape.
The Blue-ray vs. DVD debate will continue through 2007 in the consumer world. I don't see this being a major player in more conservative data centers where a big investment in the wrong choice could be costly, even if the price-per-TB is temporarily in-line with current tape technologies. IBM and others are investing a lot of Research and Development funding to continue the downward price curve for tape, and I'm not sure that optical can keep up that pace.
Well, that's my take. It is a sunny day here in China, and have more meetings to attend.

Wrapping up my week in China, I read an article by Li Xing in the local "China Daily" about energy efficiency in buildings. She argues that it is not enough for a building to be energy-efficient on its own, but you have to consider the impact of the other buildings around. Does it reflect the sun so harshly into neighboring windows that people are forced to put up blinds and use artificial light? Does it block the sun, so that rooms that previously could be used with natural sunlight must now be artificially lit?
A similar effect happens with power and cooling in the data center. Servers and storage systems generate heat, and that heat affects all the other equipment in the data center. IBM has the most power-efficient and heat-efficient servers and storage, but that is not enough. You have to consider the heat generated by all systems that might raise overall temperature.
This is what motivated IBM to deliver the IBM Rear Door Heat eXchanger, a member of IBM's CoolBlue(tm) portfolio.
According to a press release:
Research has indicated that water can remove far more heat per volume unit than air. For example, in order to disperse 1,000 watts, with 10 degree temperature difference, only 24 gallons of water per hour is needed, while the same space would require nearly 11,475 cubic feet of air. IBM's Rear Door Heat eXchanger helps keep growing datacenters at safe temperatures, without adding AC units. The unobtrusive solution brings more cooling capacity to areas where heat is the greatest -- around racks of servers with more powerful and multiple processors.
The CoolBlue portfolio of IBM innovations includes comprehensive hardware and systems-management tools for computing environments, enabling clients to better optimize the power consumption, management and cooling of infrastructure at the system, rack and datacenter levels. The CoolBlue portfolio includes IBM PowerConfigurator, PowerExecutive, and Rear Door Heat eXchanger.
The eXchanger works on standard 42U racks, and can help clients deal with the rapid growth of rack-mounted servers and storage on their raised floor. How cool is that!

I am back from China, and now glad to be back in the old USA. Last week, someone asked me what would it take to add a specific feature to the IBM System Storage DS8300. The what-would-it-take question is well-known among development circles informally as a "sizing" effort, or more formally as "Development Expense" estimate.
For software engineering projects, the process was simply that an architect would estimate the number of "Lines of Code" (LOC) typically represented in thousands of lines of code (KLOC). This single number would convert to another single number, "person-months", which would then translate to another single number "dollars". Once you had KLOC, the rest followed directly from a formula, average or rule-of-thumb.
More amazing is that this single number could then determine a variety of other numbers, the number of total months for the schedule, the number of developers, testers, publication writers and quality assurance team members needed, and so on. Again, these were developed using a formula, developed and based on past experience of similar projects.
Earlier in my career, I was the lead architect for DFSMS for the z/OS operating system, and later for IBM TotalStorage Productivity Center, performing these sizing efforts. A famous IBM architect, Frederick P. Brooks, wrote a now-classic book that was requiredreading when I started at IBM, which just was re-released as Mythical Man-Month: Essays in Software Engineering, 20th Anniversary Edition. In addition to sound advice, he alsooffered a formula or two that helps with these estimating tasks.
Hardware design introduces a different set of challenges. When I was getting my Masters Degree in Electrical Engineering, it took myself and four other grad students a full semester just to design a six-layer, 900 transistor silicon chip, which could only perform a single function, multiply two numbers together.At IBM, another book that I was given to read was Soul of a New Machine, documenting six hardware engineers, and six software engineers, working long hours on a tight schedule to produce a new computer for Data General.
So why do I bring this up now? IBM architects William Goddard and John Lynott are being inducted posthumously this year into the prestigious National Inventors Hall of Fame for their disk system innovation.
Under the leadership of Reynold Johnson, the team developed an air-bearing head to “float” above the disk without crashing into the disk. Imagine a fighter airplane flying full speed across the country-side at 50 feet off the ground. If you every heard the term "my disk crashed", it was originally referring to the read/write head touching the disk surface, causing terrible damage.
A uniformly flat disk surface was created by spinning the coating onto the rapidly rotating disk, leaving many wearing lab coats covered with disk liquid at waist level. Developing disk-to-disk and track-to-track access mechanisms proved more challenging, and nearly halted the project. The team, however, was adamant that this problem could be solved, and customers were increasingly asking for random access technology. The result was the "350 Disk Storage Unit" designed for the "305 RAMAC computer", which I have talked about a lot last year as part of our "50 years of disk systems innovation" celebration.
Neither Goddard nor Lynott had computing experience prior to joining IBM. Goddard was a former science teacher who briefly worked in aerospace. Lynott had been a mechanic in the Navy and later a mechanical engineer. They didn't have a nice formula based on past experience, they didn't have the benefit of Fred Brooks' advice, or the rules-of-thumb or averages now used to estimate the size of projects. They had to break new ground.
Now that's innovation!

In case you haven't noticed, IBM System Storage makes most of their announcements on Tuesdays. IBM announced a lot today, so here is a quick run-down.
- Cisco storage networking products
IBM continues to resell Cisco switches and directors, but now can offer these with a 1-year IBM warranty.
The entry-level Cisco 9124offers 8 to 24 ports. For IBM BladeCenter, IBM now offers the Cisco10-port and 20-port modules that slide into the back of the chassis, and are functionally equivalent to the 9124.The original BladeCenter came with a 16-port module with 14 internal, but only 2 external, which severely hamperedbandwidth connectivity to external storage. These new modules provide more external ports to relieve that constraint.
The midrange Cisco9200switches have two models, both with 16 fixed ports, with the option for a blade that can provide 12, 24 or 48 additional ports. The 9216A has 16 FCP ports, and the 9216i has 14 FCP ports, and 2 GbE ports to act as a router, such as toconnect to a remote location for business continuity using Metro Mirror or Global Mirror.
The enterprise-class Cisco 9500directors can support up to 528 ports.
- TS3400 Tape Library
The new TS3400library is a small entry-level size library, supporting the enterprise-class TS1120 drive, providing interoperabilitywith the larger tape libraries, with all the support for tape encryption.
In addition to Linux, Unix, and WIndows, the TS1120 can now be connected to System i servers. In the past, the only IBMtape available to System i were the LTO models. There are a lot of businesses that need to comply with government regulations that are looking for tape encryption, and now IBM has made it accessible to more clients.
- 300GB drives at 15K RPM
The DS8000 can now support new drives with 300GB capacity at 15,000 RPM (15K). These can be up to 30 percent faster than the 10,000 RPM drives for typical workloads.
IBM continues its market leadership with these new set of features and offerings!

I am still wiping the coffee off my computer screen, inadvertently sprayed when I took a sip while reading HDS' uber-blogger Hu Yoshida's post on storage virtualization andvendor lock-in
. This blog appears to be the text version of theirfunny video
While most of the post is accurate and well-stated, two opinions particular caught my eye. I'll be nice and call them opinions, since these are blogs, and always subject to interpretation. I'll put quotes around them so that people will correctly relate these to Hu, and not me.
"Storage virtualization can only be done in a storage controller. Currently Hitachi is the only vendor to provide this."
-- Hu Yoshida
Hu, I enjoy all of your blog entries, but you should know better. HDS is fairly new-comer to the storage virtualization arena, so since IBM has been doing this for decades, I will bring you and the rest of the readers up to speed. I am not starting a blog-fight, just want to provide some additional information for clients to consider when making choices in the marketplace.
First, let's clarify the terminology. I will use 'storage' in the broad sense, including anything that can hold 1's and 0's, including memory, spinning disk media, and plastic tape media. These all have different mechanisms and access methods, based on their physical geometry and characteristics. The concept of 'virtualization' is any technology that makes one set of resources look like another set of resources with more preferable characteristics, and this applies to storage as well as servers and networks. Finally, 'storage controller' is any device with the intelligence to talk to a server and handle its read and write requests.
Second, let's take a look at all the different flavors of storage virtualization that IBM has developed over the past 30 years.
IBM introduces the S/370 with the OS/VS1 operating system. "VS" here refers to virtual storage, and in this case internal server memory was swapped out to physical disk. Using a table mapping, disk was made to look like an extension of main memory.
IBM introduces the IBM 3850 Mass Storage System (MSS). Until this time, programs that ran on mainframes had to be acutely aware of the device types being written, as each device type had different block, track and cylinder sizes, so a program written for one device type would have to be modified to work with a different device type. The MSS was able to take four 3350 disks, and a lot of tapes, and make them look like older 3330 disks, since most programs were still written for the 3330 format. The MSS was a way to deliver new 3350 disk to a 3330-oriented ecosystem, and greatly reduce the cost by handling tape on the back end. The table mapping was one virtual 3330 disk (100 MB) to two physical tapes (50 MB each). Back then, all of the mainframe disk systems had separate controllers. The 3850 used a 3831 controller that talked to the servers.
IBM invents Redundant Array of Independent Disk (RAID) technology. The table mapping is one or more virtual "Logical Units" (or "LUNs") to two or more physical disks. Data is striped, mirrored and paritied across the physical drives, making the LUNs look and feel like disks, but with faster performance and higher reliability than the physical drives they were mapped to. RAID could be implemented in the server as software, on top or embedded into the operating system, in the host bus adapter, or on the controller itself. The vendor that provided the RAID software or HBA did not have to be the same as the vendor that provided the disk, so in a sense, this avoided "vendor lock-in".Today, RAID is almost always done in the external storage controller.
IBM introduces the Personal Computer. One of the features of DOS is the ability to make a "RAM drive". This is technology that runs in the operating system to make internal memory look and feel like an external drive letter. Applications that already knew how to read and write to drive letters could work unmodified with these new RAM drives. This had the advantage that the files would be erased when the system was turned off, so it was perfect for temporary files. Of course, other operating systems today have this feature, UNIX has a /tmp directory in memory, and z/OS uses VIO storage pools.
This is important, as memory would be made to look like disk externally, as "cache", in the 1990s.
IBM AIX v3 introduces Logical Volume Manager (LVM). LVM maps the LUNs from external RAID controllers into virtual disks inside the UNIX server. The mapping can combine the capacity of multiple physical LUNs into a large internal volume. This was all done by software within the server, completely independent of the storage vendor, so again no lock-in.
IBM introduces the Virtual Tape Server (VTS). This was a disk array that emulated a tape library. A mapping of virtual tapes to physical tapes was done to allow full utilization of larger and larger tape cartridges. While many people today mistakenly equate "storage virtualization" with "disk virtualization", in reality it can be implemented on other forms of storage. The disk array was referred to as the "Tape Volume Cache". By using disk, the VTS could mount an empty "scratch" tape instantaneously, since no physical tape had to be mounted for this purpose.
Contradicting its "tape is dead" mantra, EMC later developed its CLARiiON disk library that emulates a virtual tape library (VTL).
IBM introduces the SAN Volume Controller. It involves mapping virtual disks to manage disks that could be from different frames from different vendors. Like other controllers, the SVC has multiple processors and cache memory, with the intelligence to talk to servers, and is similar in functionality to the controller components you might find inside monolithic "controller+disk" configurations like the IBM DS8300, EMC Symmetrix, or HDS TagmaStore USP. SVC can map the virtual disk to physical disk one-for-one in "image mode", as HDS does, or can also map virtual disks across physical managed disks, using a similar mapping table, to provide advantages like performance improvement through striping. You can take any virtual disk out of the SVC system simply by migrating it back to "image mode" and disconnecting the LUN from management. Again, no vendor lock-in.
The HDS USP and NSC can run as regular disk systems without virtualization, or the virtualization can be enabled to allow external disks from other vendors. HDS usually counts all USP and NSC sold, but never mention what percentage these have external disks attached in virtualization mode. Either they don't track this, or too embarrassed to publish the number. (My guess: single digit percentage).
Few people remember that IBM also introduced virtualization in both controller+disk and SAN switch form factors. The controller+disk version was called "SAN Integration Server", but people didn't like the "vendor lock-in" having to buy the internal disk from IBM. They preferred having it all external disk, with plenty of vendor choices. This is perhaps why Hitachi now offers a disk-less version of the NSC 55, in an attempt to be more like IBM's SVC.
IBM also had introduced the IBM SVC for Cisco 9000 blade. Our clients didn't want to upgrade their SAN switch networking gear just to get the benefits of disk virtualization. Perhaps this is the same reason EMC has done so poorly with its "Invista" offering.
So, bottom line, storage virtualization can, and has, been delivered in the operating system software, in the server's host bus adapter, inside SAN switches, and in storage controllers. It can be delivered anywhere in the path between application and physical media. Today, the two major vendors that provide disk virtualization "in the storage controller" are IBM and HDS, and the three major vendors that provide tape virtualization "in the storage controller" are IBM, Sun/STK, and EMC. All of these involve a mapping of logical to physical resources. Hitachi uses a one-for-one mapping, whereas IBM additionally offers more sophisticated mappings as well.

I didn't really have a theme this week, still recovering from jet-lag from my travels through Japan, Australia, China.
Gary Diskman has an amusing blog entry about a Funny disaster recovery job posting. It is not clear if he is being completely tongue-in-cheek, or a bit cynical. However, it rings true that you get what you measure, and some managers look for easy metrics, even if there are unintended consequences.
Western medicine works this way. Rather than paying your doctor to keep you healthy, you pay him per visit, to get refills on prescriptions, check-ups on medical conditions, surgeries and so on. While Eastern medicine is focused on keeping people healthy, Western medicine profits more from resolving "situations".
I have seen similar situations on the "health" of the data center. In one case, the admins were measured on how quickly they bring back up their web-servers after a crash. They had this process down to a science, because they were measured on how quickly they resolved the situation. I suggested switching from Windows to Linux, a much more reliable operating system for web-serving, and showed examples of web-servers running Linux that have been up for 1000 days or more. Management changed the metrics to "average up-time in days" and magically the re-boots all but disappeared, thanks to Linux, but also thanks in part to shifting the incentive structure. Perhaps some of those earlier situations were "artificially created"?
Back in the 1980s, I was working on a small software project that was about 5000 lines of code. In those days, testers were measured by the number of "successful" testcases that ran without incident. Testcases that uncovered an error were labeled as "failures" to be re-run after the developers fixed the code. When I declared my code ready for test, the test team ran 110 testcases, all successfully, and they were all rewarded for meeting their schedule. I, on the other hand, did not accept these results, met with them and told them I would give them $100 each if they could find a bug in my code in the next week. Nobody writes 5000 lines of code without some error along the way, not even me. (As one author put it, more people have left earth's gravity to orbit the planet than have written perfect code that did not require subsequent review or testing. It's so true. Good software is difficult to write.)
The test team accepted the challenge, and found 6 problems, more than I expected, but at least I felt more confident of the code quality after fixing these. As I suspected, the unintended consequence of counting "successful" testcases was that testers would write the most simple, basic, least-likely-to-challenge-boundaries testcases to ensure they meet their numbers. My experiment was costly to me, but more importantly was a wake-up call for the test management, and they realized they needed to re-evaluate their test procedures, metrics and terminology. This was a long time ago, and I am glad to see that the overall "software engineering" practice has matured much over the past 20 years.
So, my advice is to determine metrics that have the intended consequences you want, while avoiding any negative unintented consequences that might undermine your eventual success. People will quickly figure out how to maximize the results, and if you can align their goals to company goals, then everybody benefits.
Well, I'll be blogging from Mexico next week (yes, it is a business trip!). Enjoy the weekend.

Today, I went looking for reading-glasses. Unfamiliar with my surroundings, I asked several people where I might be able to find and purchase these, and was sent in various directions. My first stop was a bookstore. It would make sense that since many people need reading glasses to read the books, that they would sell them there, but no. The staff didn't know where I could go, but pointed me in the direction of a mall. At the mall, I found a pharmacy. Many pharmacies sell reading glasses, so I stopped in, but no, not this one. The pharmacists suggested the super-store nearby. I walked in to the super-store, and asked the first employee where they keep their reading glasses, and they said the other corner. The other corner was the electronics department. It made sense that they sold CDs and DVDs in the same section as the equipment that plays them, but reading glasses? Skeptical, I went to the pharmacy department, and the young and beautiful lady (everyone is young, thin and beautiful here) had me follow her, and she led me back to the electronics department, whereupon she pointed to a rack of sunglasses. I indicated that I need reading glasses, not sunglasses. She pulled one out, and it was indeed reading glasses, 1.25, just what I was looking for. Others were tinted, so you can read the newspaper out in the sunlight. The pair I chose cost only $97 in the local currency.
After reading the last sentence, you might be thinking I am describing my "avatar" in Second Life, but no, I am talking about my search for reading glasses on the streets of Mexico. I am here this week in meetings with IBM Business Partners and sales reps to discuss IBM's latest System Storage products and offerings.
We used to tell people they should "clothe" servers with storage. IBM offers both, so yes it makes sense to offer both as part of a complete solution. However, when you look through a dictionary definition "to clothe" you learn it is to dress, wrap or cover with clothing, an implication that it is external, and perhaps temporary, easily changed, like switching from sunglasses to reading glasses. In Second Life, objects can be "worn", simply by attaching or detaching them to your "avatar". Sometimes clothing serves a purpose, like reading glasses, provides protection, like raincoats, and other times, more decorative, like"icing on the cake" or "gold plating".
This concept was fine 50 years ago, when we were in a server-centric world, and dumb storage devices were attached to very intelligent servers. Back then, we used the derogatory term "subsystems" to emphasize that storage was just part of the server, not a system of its own.
Today, we live in an information-centric world. The information outlives the media, and the media outlives the servers that access it. It is not unreasonable to attach dozens or hundreds of servers to a single storage system, or collection of storage systems. Over 20 percent of IBM System Storage DS8000 series, for example, are attached to Windows rack-optimized or blade servers. Imagine a refrigerator surrounded by dozens or hundreds of pizza boxes. Storage is no longer a subsystem, but a system on its own right, dressed, wrapped or covered by servers that deliver the right information, to the right people, at the right time.
So perhaps we should reverse it, telling people they should "clothe" their storage with servers!

Well, I'm back from Mexico.
The flight back was uneventful, except for the leg from Houston to Tucson. The lady in the window seat had "overallocated storage" and required a "distance extension" on her safety belt. To accomodate her, her husband and I flipped up the "logical partitions" between the seats, and "compressed" to take up less space to accomodate. Luckily, it was only for two hours.
On the flight to Houston, I was asked what kind of drink I wanted, in Spanish, as the crew were all from Mexico. Here's a quick Spanish lesson:
- this stands for drink in general, and can include liquor and soft drinks
- this stands generically for soft drink. They will often use "Coke" to refer to any cola beverage, regardless of brand.
It is interesting that Spanish language in each country is slightly different. The Mexicans I met with and spoke Spanish to immediately recognized I was from South America, and not from Central America. Likewise, folks in Puerto Rico knew I was from somewhere from South America, and not from Mexico or Central America. In Columbia, Argentina, and even Brazil, my speech is more recognizable as being from Bolivia.
Before IBM got into an OEM agreement with Network Appliance, I used to indicate that EMC and NetApp were the "Coke and Pepsi" of the NAS marketplace. IBM had a presence, but it was in the single digits, whereas these two major players had roughly equal marketshare, just as Coke and Pepsi dominate equally the US marketplace. That analogy doesn't work in other countries, as in some cases the country might be more heavily in favor of one or the other.
On my flight over from Houston to Tucson, however, I was asked what kind of "pop" I wanted. I always say "soda" to refer generically to soft drinks, but realize that others say "pop" instead. Not only can Americans be able to detect what part of the country people are from by accent, but also by the words they use.
Now I see a blog that explores in great detail the issue of Pop vs Soda vs Coke.
So, it looks like I'll need to "retire" my Coke vs. Pepsi analogy, not because their marketshare has changed, but because IBM's parntering with NetApp greatly skews the advantage over EMC.

Back in 1986, when I first started with IBM, my first job was working on a software product called Data Facility Hierarchical Storage Manager (DFHSM). This did "Information Lifecycle Management" (ILM) by moving data sets from one storage tier to another. (The phrase "Information Lifecycle Management" was coined by StorageTek in 1991, and later resurrected by EMC a few years ago. As is often typical, things that appear new to the distributed systems crowd, are often well-established concepts in the mainframe arena).
To help explain DFHSM and its sister product Data Facility Data Set Services (DFDSS), an enterprising sales rep in Los Angeles named C.D. Larsen made a video called "Re-arranging the sock drawer". He explained that sometimes you want the socks you wear the most on the top drawer, and socks that you only wear now and again in lower drawers. DFHSM can re-arrange your sock drawer based on policy-based automation, determining which ones you wear most often, and moving the others down the "hierarchy" accordingly.
To explain DFDSS, he pulled out an entire drawer of socks, and move it to another level. DFDSS was able to do volume-level backups and dumps to tape very quickly, since it did not process individual data sets, but rather the entire volume image as a whole. These two products are now DFSMShsm and DFSMSdss components of the DFSMS element of the z/OS operating system.
Mainframes use an interesting naming convention for its data sets. 44 characters, divided up into qualifiers that are 1-8 characters long, separated by periods. For example:
The first qualifier indicated it belonged to me, that it was for my Project A, that it was a testcase, and specifically TEST1 job control language. Arranging them in this order meant that I could easily find all the data needed for project A, but if I wanted to keep all the testcase data together, I might have put that as the second qualifer instead.
On Linux, UNIX and Windows, most people are more familiar with hierarchical file systems, so the same file might be stored as:
Same concept. You set up a taxonomy of they way you want to organize your data, so that related data can be grouped together and easier to manage. Whereas we used to tell customers that "Qualifiers are your friend", we now tell people "sub-directories are your friend". This is true when organizing the files on your laptop, in your Lotus Notes, and in Second Life.
Since starting Second Life last November, I have picked up all kinds of free things along the way, and now have thousands of objects in my "inventory". Basically, its like keeping things in your pocket, when you want it, you just take it out of your pocket, and *poof* it appears magically on the ground. I was having a hard time finding things in my inventory, so I decided to re-arrange with sub-folders. This is done in-world, and I found it best to do this away from other avatars asking "what are you doing?" which can get quite annoying. Find a remote island or the rooftop of some building when doing "house cleaning".
I've arranged my main folders as follows. These all appear on a single screen, and makes it easy to find exactly what I am looking for.
- Body Parts
- Calling Cards
- Lost and Found
- Photo Album
In Second Life, you can make complete "outfits" which include your body shape, skin, eyes, hair, and clothes. However, saving away many outfits means duplicating a lot of items. Therefore, I separated them out. I keep body shape, skin, eyes and hair in the folder "Body Parts" and all of the clothing items under "Clothing". Under clothing, I separated everything out into the major categories:
I could have a separate folder for "socks", but I keep those in the "shoes" folder.

Tonight I had dinner with Henry Daboub (an SVC expert from Houston, TX) and some clients, who asked what I would blog about tonight, and I figured it made sense to blog about the SVC.
Hu Yoshida clarifies his position about storage virtualization, including the statement: "As a result they can not provide the availability, scalability, and performance of a DS8300. If they could, there would be no need for a DS8300."
Of course, if humans descended from apes, why are there still apes? Now that we have cars, why are there still trains? But perhaps a better question is: now that there are supercomputers, why are there still mainframe servers?
The issue is the difference between scale-up versus scale-out. Scale-up is making a single box as big and beefy as possible. When the SVC was introduced, the major vendors all had scale-up designs: IBM ESS 800, HDS Lightning, EMC Symmetrix. Like the mainframe, they were for customers that wanted everything in a single monolithic container.
SAN Volume Controller was the result of IBM Research asking the question, if you could put anyone's software (feature and functionality) on anyone's hardware (monolithic scale-up design), what combination would you choose? What if the brains inside today's monolithic systems could be snapped into the another vendor's frame? What if you could run SRDF on an HDS box, or ShadowImage on an IBM box? The surprising response was that most customers would want a single software for consistency, but wanted the option to choose from different vendors hardware, to negotiate the best price of the commodity iron. Based on this feedback, the SVC was born.
The idea was simple, put all the brains in a separate appliance. The appliance would do the non-disruptive migrations, the caching, the striping, and all the copy services. This lets the customer chose then the hardware they want, any mix of FC and ATA disk, from any vendor.
The SVC design was based on IBM's long history in supercomputers. Using the same "scale-out" technology, the power comes not from having it all in one monolithic box, but rather in a design that combines small nodes together. While the cache is not globally shared, the data is shared between node-pairs, and the logical-to-physical mapping is routed around to all nodes in a cluster. Each SVC node talks to each other SVC node through the FCP ports, eliminating the need for additional wiring. For the most part, each node does its own separate work, but when it needs to, they can communicate across, just like nodes in a supercomputer.
Both the SVC and the DS8300 Turbo have better than 99.999 percent availability, based on redundant components designed for no single point of failure (SPOF). IBM has sold thousands of each, and they have been in the field enough time that we can make that claim. There is nothing between scale-up versus scale-out that makes on inherently more available than the other.
Both the SVC and the DS8300 Turbo can scale from as little as a few TB of disk, to hundreds of TB of disk. We have yet to meet a customer that is too big for the SVC. The DS8300 Turbo is able to scale by adding up to four extension frames, but is still considered a single box from a scale-up perspective. From a processor perspective, an 8-node SVC cluster has 16 Intel Xeon processors, and the DS8300 has 8 POWER5+ processors (dual 4-way). The key advantage of scale-out is that you can add capacity to the SVC in smaller increments. Jumping from a DS8100 (dual 2-way) to a DS8300 (dual 4-way) is a big jump.
SVC remains the fastest disk system in the industry, based on both the SPC-1 and SPC-2 benchmarks. The latest model now supports 8GB per node, for a total of 64GB for an 8-node cluster. This can be used for both read and write non-volatile storage. By comparison, DS8300 Turbo has 32GB write non-volatile storage, and up to 256 GB of read-only cache. The SVC is able to do 155,519 IOPS, faster than the 123,030 IOPS for the DS8300, and of course faster than anything from EMC, HDS, HP or Texas Memory Systems. Of course, workloads vary, and there might be some workloads where the 256GB of read-only cache of the monolithic DS8300 is the better choice.
- copy services
Both SVC and DS8300 Turbo offer FlashCopy (point-in-time copy), Metro Mirror (synchronous) and Global Mirror (asynchronous). SVC provides the additional benefit that it can perform a FlashCopy from one frame to another, and the ability to migrate data seemlessly from one box to another.
Interestingly, IBM has seen a resurgence in both mainframe sales, as well as interest in supercomputers. Both have their place, based on the workload characteristics, and so IBM will continue to offer both modular scale-out designs, as well as monolithic scale-up designs, to meet the different needs of the marketplace.

Sometimes, it's difficult to explain the products I manage to people outside the IT storage industry. How do you explain FCP vs. FICON, Giant Magnetoresistive (GMR) heads, the SMI-S interface, etc. enough to then explain how your job relates to those technologies. At least my friends and family read this blog, so they can somewhat understand some of the things I am working on. When I visit my folks on Sundays, we sometimes discuss items they read in my blog that week.
In addition to a "take your children to work day", we have discussed within IBM a "take your parents to work day", especially for the young new hires who have a hard time explaining what their new job is to the rest of their family.
Seth Godin points to a video ad to fill a job position and the confusion therein with the "recruiter" who just doesn't understand the job involved.
The problem is not just your parents, but any of your co-workers old enough to be parents who haven't bothered to keep up with the latest advancements in Web 2.0 technology. Here are some examples:
- A project leader working with a technology partner asked if me if there was a difference between a "blog" and a "wiki" and which should his team use. This was not a simple yes/no answer, and involved some explanation, conversation and understanding of what he was trying to accomplish.
- For one of my meetings, someone instant-messaged me asking where it was, was it "face-to-face" (F2F) or Conference call (CC). I replied back, "A2A w/CC" (avatar-to-avatar with voice over conference call). When you are meeting other avatars in-world in Second Life, it gets quite distracting having everyone typing away, with their hands and fingers moving furiously, so we use a conference call to complement our 3D interaction.
That's why I was very excited to seeLinden Lab announces voice beta in Second Life. It won't be fully ready until later this year, but adding voice to Second Life will greatly reduce the hurdles we now have trying to coordinate conference calls with in-world activity.
I realize not everyone can keep up with all the new and different technologies, but the social networking aspects of some of these new developments are worth looking into.

Well, this week I am in Maryland, just outside of Washington DC. It's a bit cold here.
Robin Harris over at StorageMojo put out this Open Letter to Seagate, Hitachi GST, EMC, HP, NetApp, IBM and Sun about the results of two academic papers, one from Google, and another from Carnegie Mellon University (CMU). The papers imply that the disk drive module (DDM) manufacturers have perhaps misrepresented their reliability estimates, and asks major vendors to respond. So far, NetAppand EMC have responded.
I will not bother to re-iterate or repeat what others have said already, but make just a few points. Robin, you are free to consider this "my" official response if you like to post it on your blog, or point to mine, whatever is easier for you. Given that IBM no longer manufacturers the DDMs we use inside our disk systems, there may not be any reason for a more formal response.
- Coke and Pepsi buy sugar, Nutrasweet and Splenda from the same sources
Somehow, this doesn't surprise anyone. Coke and Pepsi don't own their own sugar cane fields, and even their bottlers are separate companies. Their job is to assemble the components using super-secret recipes to make something that tastes good.
IBM, EMC and NetApp don't make DDMs that are mentioned in either academic study. Different IBM storage systems uses one or more of the following DDM suppliers:
- Seagate (including Maxstor they acquired)
- Hitachi Global Storage Technologies, HGST (former IBM division sold off to Hitachi)
In the past, corporations like IBM was very "vertically-integrated", making every component of every system delivered.IBM was the first to bring disk systems to market, and led the major enhancements that exist in nearly all disk drives manufactured today. Today, however, our value-add is to take standard components, and use our super-secret recipe to make something that provides unique value to the marketplace. Not surprisingly, EMC, HP, Sun and NetApp also don't make their own DDMs. Hitachi is perhaps the last major disk systems vendor that also has a DDM manufacturing division.
So, my point is that disk systems are the next layer up. Everyone knows that individual components fail. Unlike CPUs or Memory, disks actually have moving parts, so you would expect them to fail more often compared to just "chips".
If you don't feel the MTBF or AFR estimates posted by these suppliers are valid, go after them, not the disk systems vendors that use their supplies. While IBM does qualify DDM suppliers for each purpose, we are basically purchasing them from the same major vendors as all of our competitors. I suspect you won't get much more than the responses you posted from Seagate and HGST.
- American car owners replace their cars every 59 months
According to a frequently cited auto market research firm, the average time before the original owner transfers their vehicle -- purchased or leased -- is currently 59 months.Both studies mention that customers have a different "definition" of failure than manufacturers, and often replace the drives before they are completely kaput. The same is true for cars. Americans give various reasons why they trade in their less-than-five-year cars for newer models. Disk technologies advance at a faster pace, so it makes sense to change drives for other business reasons, for speed and capacity improvements, lower power consumption, and so on.
The CMU study indicated that 43 percent of drives were replaced before they were completely dead.So, if General Motors estimated their cars lasted 9 years, and Toyota estimated 11 years, people still replace them sooner, for other reasons.
At IBM, we remind people that "data outlives the media". True for disk, and true for tape. Neither is "permanent storage", but rather a temporary resting point until the data is transferred to the next media. For this reason, IBM is focused on solutions and disk systems that plan for this inevitable migration process. IBM System Storage SAN Volume Controller is able to move active data from one disk system to another; IBM Tivoli Storage Manager is able to move backup copies from one tape to another; and IBM System Storage DR550 is able to move archive copies from disk and tape to newer disk and tape.
If you had only one car, then having that one and only vehicle die could be quite disrupting. However, companies that have fleet cars, like Hertz Car Rentals, don't wait for their cars to completely stop running either, they replace them well before that happens. For a large company with a large fleet of cars, regularly scheduled replacement is just part of doing business.
This brings us to the subject of RAID. No question that RAID 5 provides better reliability than having just a bunch of disks (JBOD). Certainly, three copies of data across separate disks, a variation of RAID 1, will provide even more protection, but for a price.
Robin mentions the "Auto-correlation" effect. Disk failures bunch up, so one recent failure might mean another DDM, somewhere in the environment, will probably fail soon also. For it to make a difference, it would (a) have to be a DDM in the same RAID 5 rank, and (b) have to occur during the time the first drive is being rebuilt to a spare volume.
- The human body replaces skin cells every day
So there are individual DDMs, manufactured by the suppliers above; disk systems, manufactured by IBM and others, and then your entire IT infrastructure. Beyond the disk system, you probably have redundant fabrics, clustered servers and multiple data paths, because eventually hardware fails.
People might realize that the human body replaces skin cells every day. Other cells are replaced frequently, within seven days, and others less frequently, taking a year or so to be replaced. I'm over 40 years old, but most of my cells are less than 9 years old. This is possible because information, data in the form of DNA, is moved from old cells to new cells, keeping the infrastructure (my body) alive.
Our clients should approach this in a more holistic view. You will replace disks in less than 3-5 years. While tape cartridges can retain their data for 20 years, most people change their tape drives every 7-9 years, and so tape data needs to be moved from old to new cartridges. Focus on your information, not individual DDMs.
What does this mean for DDM failures. When it happens, the disk system re-routes requests to a spare disk, rebuilding the data from RAID 5 parity, giving storage admins time to replace the failed unit. During the few hours this process takes place, you are either taking a backup, or crossing your fingers.Note: for RAID5 the time to rebuild is proportional to the number of disks in the rank, so smaller ranks can be rebuilt faster than larger ranks. To make matters worse, the slower RPM speeds and higher capacities of ATA disks means that the rebuild process could take longer than smaller capacity, higher speed FC/SCSI disk.
According to the Google study, a large portion of the DDM replacements had no SMART errors to warn that it was going to happen. To protect your infrastructure, you need to make sure you have current backups of all your data. IBM TotalStorage Productivity Center can help identify all the data that is "at risk", those files that have no backup, no copy, and no current backup since the file was most recently changed. A well-run shop keeps their "at risk" files below 3 percent.
So, where does that leave us?
- ATA drives are probably as reliable as FC/SCSI disk. Customers should chose which to use based on performance and workload characteristics. FC/SCSI drives are more expensive because they are designed to run at faster speeds, required by some enterprises for some workloads. IBM offers both, and has tools to help estimate which products are the best match to your requirements.
- RAID 5 is just one of the many choices of trade-offs between cost and protection of data. For some data, JBOD might be enough. For other data that is more mission critical, you might choose keeping two or three copies. Data protection is more than just using RAID, you need to also consider point-in-time copies, synchronous or asynchronous disk mirroring, continuous data protection (CDP), and backup to tape media. IBM can help show you how.
- Disk systems, and IT environments in general, are higher-level concepts to transcend the failures of individual components. DDM components will fail. Cache memory will fail. CPUs will fail. Choose a disk systems vendor that combines technologies in unique and innovative ways that take these possibilities into account, designed for no single point of failure, and no single point of repair.
So, Robin, from IBM's perspective, our hands are clean. Thank you for bringing this to our attention and for giving me the opportunity to highlight IBM's superiority at the systems level.

Tuesday is always good for announcements. Today, Gartner, Inc.
announced that IBM has taken over HP in its climb to the top. I'll quote directly from today's press release:
STAMFORD, Conn., March 6, 2007 — Worldwide external controller-based (ECB) disk storage revenue totaled $15.2 billion in 2006, a 4.1 percent increase over 2005 revenue of $14.6 billion, according to Gartner, Inc.IBM overtook Hewlett-Packard for the No. 2 position in 2006 (see Table 1). IBM’s worldwide ECB market share increased to 15.8 percent, while HP’s market share dropped to 13.1 percent.
IBM beat HP both in 4Q06, as well as 2006 full year.You can read more about it from Gartner Dataquest report “Market Share: Disk Array Storage, All Regions, All Countries, 1Q05-4Q06" on their website. (Note: non-IBMers might need an account with Gartner to access this, not sure)
The focus was on external controller-based disk, not external controller-less SCSI/SAS disk, not disk arrays posing as virtual tape libraries, nor any disk sold inside HP, Sun, IBM or Dell servers. This is to compare with disk-only vendors such as EMC and HDS. The revenues reflect hardware only, including hardware-related parts of financial leases and managed services. Revenues from optional priced software features such as multi-pathing drivers, management software, or advanced copy services were excluded.I discussed these types of analyst reports back in blog post last September: Space Race Heats Up.
These marketshare numbers are based on revenues, not units or terabytes. When a box gets sold, the revenue was counted toward the vendor that sold it, not the manufacturer that built it. In this last report:
- When Dell sells an EMC box, it gets counted as Dell. When Fujitsu Siemens sells an EMC box, it gets counted as "Other".
- When HP sells an HDS box, it gets counted as HP. When Sun sells the HDS box, it gets counted as Sun.
- When IBM sells its System Storage N series (from the OEM agreement with NetApp), it gets counted as IBM. Both IBM and NetApp experienced growth in the NAS/unified storage arena.
It's still cold here in the Washington DC area, but at least good news like this helps warm me up!

For those interested in performance, my IBM colleague Elisabeth Stahl hasstarted up her own blog on the subject, called Benchmarking and Systems Performance
. Check it out!

The blogosphere has quieted down a bit over the two papers on MTBF estimates for Disk Drive Modules (DDM).One article on SearchStorage.com by Arun Taneja asksIs RAID passé?
Disk capacity is growing at a faster rate than DDM reliability. During the hours to rebuild a DDM, companies are at risk of additional failures that could require recovery from a copy, or result in data loss, depending on how well your Business Continuity (BC) plan is written and followed.
I'll discuss two comments in particular.
Joerg Hallbauer felt I did not address all the issues raised:
... The problem with that is that it's the DISK ARRAY that determines when a drive has failed an starts the rebuild process. That IS under the control of IBM, specifically the controller. But more importantly, it effects my risk of data loss.
As I see it, my risk of data loss with RAID-5 is influenced by two main factors. 1 - The drive replacement rate and 2 - The rebuild time (which to a great extent is a function of the drive size) both of which IBM has some control over.
So, I think that the question in my mind is, what's the tipping point? Where does the risk of using RAID-5 protection exceed what I'm willing to accept, and I need to move to some other protection mechanism like RAID-6? Is it when the rebuild times exceed 12 hours? 24 hours? 48 hours?
Also, I wonder why IBM isn't publishing some information to help me make these kinds of decisions?
Bill Todd felt I was not technical enough:
Oh, dear - while Tony doesn’t seem to be parrying vigorously (as Seagate, Hitachi, and Chunk were doing), his contribution sounds more like IBM marketing than the kind of detailed, technical response one might have hoped for
... well, he *is* a manager, and a marketing one at that, so perhaps we shouldn’t expect more).
Both are fair comments. Disk arrays do run microcode to assist or perform the RAID function, detect failures and start the rebuild process, and so clever designs to support spare disks, process the rebuild quickly, and so on, can differentiate one vendor's offering from another.
On the issue of what does IBM provide to help its clients make the right decisions for their environments, Jon William Toigo at DrunkenData points his readers to IBM's Business Continuity Self-Assessment tool. In normal data center conditions, DDMs will fail, and a Business Continuity plan shouldbe written and developed to handle this fact. Using 2-site and 3-site mirroring, complemented with versions of tape backups, can help address some of these concerns and mitigate some of the risks involved with using disk systems.
For those who want a more technical answer, IBM has just published a series of IBM Redbooks.
Each client's situation is different, so no simple answer is possible. However, IBM does have a lot of experience in this area, and would be glad to help you write or update your existing Business Continuity plan.

Yesterday, most of the USA moved its clocks forward an hour. Arizona and Hawaii don't bother, as there is plenty of daylight in both states. While it may seem that Arizonans are not "affected" by Daylight Saving Time (DST)
, we are, because we have to deal with the time zone offsets with those we talk to in other states. (Note: it is SAVING not SAVINGS
, many people mistakenly say "Daylight Savings
Time", which is incorrect).
Year round, Arizona is on Mountain Standard Time (MST), which is GMT-7. Figuring out what time Arizona can be remembered by a simple mnemonic:
- In the winter time, Utah, Colorado, New Mexico, and Arizona are all on MST, so best American ski resorts are all on the same time zone. People who hop from one ski resort to another by helicopter don't have to reset their watches as they move into or out of Arizona.
- In the summer time, Arizonans head to San Diego, Los Angeles or other parts of California, where it is not so hot. California is on PDT, which is the same as MST. People who hop from Arizona wineries and vineyards to those in California and Oregon can easily cross the Arizona-California border without having to reset our watches.
Those in Second Life may have noticed that "Second Life time" (SL time) shifted from PST to PDT. That is because their servers reside in San Francisco, California.

On the news today, they mentioned it was "Happy Pi Day"
. Today is the 14th day of the 3rd month, and "pi" is about 3.14159, the ratio of the circumference of a circle to its diameter. So, in Tucson it is celebrated on 3/14, at 1:59pm MST.
The ratio has a lot to do with storage.
Tape wrapped around a hub. Tape is thin, but not completely, so wrapping hundreds of meters on tape results in a change in diameter of the spool. This impacts the rotational velocity needed to get the linear meters-per-second on the tape media consistent as the diameter changes when you wind down from a full spindle toward the hub. IBM has variable speed motors and other clever technologies to handle this adjustment.
Disks spin at consistent speeds, but tracks on the outside edge travel faster across the head than the inside tracks.Currently, the top speeds for disk are 15000 Revolutions per minute (RPM). As faster rotational speeds are investigated, the researchers find they need to make the diameters smaller to compensate.
The diameters of disks were based on "U", the unit height of standard 19" racks. A "U" is 1.75 inches, and standard floppy diskettes were 5.25 inch (3U) and 3.5 inch (2U). For those who have a difficult time remember how many inches a "U" is, it is the height of a standard two-by-four (2x4) piece of lumber.
The value of "pi" has been calculated to over a billion significant digits. Here is a cuteapplet to use if you ever need the value to any level of accuracy.

Robert Von Oech on CreativeThink remembers Ernest Gallo
, who died last week at 97 years old.
"Do you know what I do?" Mr. Mondavi recalls Mr. Gallo asked him when they first met.
"Yes, you run the largest winery in the country," recalls Mr. Mondavi, then in his mid-20s.
"No," Ernest corrected him. "I go out and visit customers in stores."
Robert Smith (aka Radio Voom) reports on National Public Radio that Second Life is now being used for campaigning for political candidates. It used to be that political candidates took trains and buses across the country, meeting people, discussing their issues, and getting a feel for what is going on in the hearts and minds of their potential voters. With the development of TV and Radio, candidates traveled less, hoping to get their word out to people who would listen to them. Using Second Life and other social networking tools brings candidates back to having conversations with the people they hope to represent.
Of course, many of these candidates are old, and are learning internet social networking skills for the first time. John McCain, my senator from Arizona, is running for President at 70 years old! It's true that old dogs CAN learn new tricks.
IBM is investing heavily into Second Life, as are many other forward-thinking companies, to explore the age-old human need for connectedness, community and dialog. I've asked my team to all get their avatars up and running in Second Life. Granted there is a bit of a learning curve, but everybody handles change in different ways, some better than others.
John Windsor on YouBlog,Marina Krakovsky inStanford Magazine,and Guy Kawasaki, all discuss the "Effort Effect" and Carol Dweck's latest book "Mindset: The New Psychology of Success". I haven't read the book yet myself, but the reviews are interesting. The IT industry is evolving fast, and embracing new technologies, new concepts, and new ideas is necessary for success.
Seth Godin takes this one step further, arguing there are two kinds of people in this world: Thrill Seekers and Fear Avoiders. Forbes just published its latest list of billionaires. The front quote on Forbes' website says it all...
"Knowledge is the antidote to fear."
-Ralph Waldo Emerson
Why are most of these guys (and girls) with over a billion US dollars in net worth still working? Perhaps because they embrace new ideas, and are on the thrill seeking side of humanity. I guess I am too. I'll be thrill-seeking in Chicago this weekend, celebrating St. Patrick's day.

Last Friday,The "Greater IBM Connection" team held a "red carpet" event, showcasing the winners of the Second Life "machinima"
.It is best explained on the Linden Lab website:
Machinima is the art of making real movies in virtual worlds.
Movies made in Second Life use the world's building, scripting, and avatar customization tools, working in real-time collaboration with people around the globe. You can use Second Life as your own virtual back lot, soundstage, choreography studio, costume and prop repository, and special effects house.
The seven videos were shown in Second Life, and are now available on YouTube for those who missed them.

The movie industry is slowly making the conversion to digital.
For about 25 years, movies were silent, actors acted, text was shown on the screen, and an organ or piano player added the musical score. My mother was a concert pianist, so I grew up listening to all kinds of piano music. Last weekend, while I was in Chicago for St. Patricks Day, we watched and listened to the dueling pianos at a bar called "Howl at the Moon". Those not familiar with this art form can watch this 1-minute video of Star Wars re-imagined as a Silent Movie.
About 80 years ago, "talkies" appeared. The sound was converted to a series of colors that were recorded as a separate strip on the film media itself, hence the name "soundtrack". When the movie ran, the colors would then be converted back to voice and music. While the live piano players were out of jobs, the move to sound created a whole new industry for foley artists, orchestras and composers.InformationWeek's Mitch Wagner explains in Something Will Be Lost thatgreat artists like Charlie Chaplin and Mary Pickford never completely made the transition to talkies.
Now the movie industry is changing again, this time from film to digital format. Thanks to digital, we can now see videos on the internet, such as this set of Impressive Palindromes parody of a Bob Dylan song.
While movies are digital when you rent them from the DVD store, download them on iTunes, or play them on YouTube, they are still mostly in analog format on 35mm or 70mm film stock when you see them on the big screen.
My first "digital projection" experience was the movie "Ice Age" shown in Denver, Colorado. The theatre owner came out to show us what film stock looks like, and then how small the DVD was that held the digital version. The theatre also showed previews of other movies first on film, then in digital, so that we could see the difference in quality.My second experience was "Star Wars: Attack of the Clones (episode II)", which I saw opening night at the Ziegfeld theatre in New York City. This was a huge theatre, and we had front row seats in the upper balcony.
Of course, the transition of film stock to digital projection is just one of the many trends resulting in the fast growth of computer IT storage. Documents transitioned from paper, to being scanned into digital format, to being created digitally using word processing software. Likewise, photographs went from film, to being scanned, to being captured with digital cameras.
As with talkies, history repeats itself; the transition to digital projection is not going smoothly.NPR's Laura Sydell reports thatDigital Projection in Theaters Slowed by Dispute. The dispute is between movie production companies and theatre owners. Currently, it is quite expensive to send out film stock to all the theatres, so the transition to digital will save the movie production companies lots of money. On the other hand, installing digital projection equipment will be costly for theatre owners. How the two groups will share the burdensome costs to convert this infrastructure is still under negotiation.
As a fan of going to the movies, I hope they resolve this dispute soon.

The amount of information stored and available today is astounding. Consider the following:
...a weekday edition of The New York Times contains more information than the average person was likely to come across in a lifetime in seventeenth-century England.
Richard Wurman, Information Anxiety. 1989.
Shawn Callahan mentions this in his great presentation on how work really gets done.
Mark Nelson covers this in more detail inWe Have the Information You Want, But Getting It Will Cost You: Being Held Hostage by Information Overload.
To help address this challenge of organizing finding the right information at the right time, Web 2.0 technologies have emerged. You can read the 16-page paper What Is Web 2.0? -- Design Patterns and Business Models for the Next Generation by O'Reilly.
Or better yet, watch the quick 4-minute video Web 2.0 ... The Machine is Us/Ing Us.

As an alumni of the University of Arizona
, it is always good to see any of the Arizona schools try something new and innovative. This time, it was our arch-rivals atArizona State University
(in Tempe, AZ, near Phoenix).
An article in InformationWeek reports that40,000 ASU Students Leap to Google Apps; University Pays Zero. The ASU president, Michael Crow, wants to make IT the primary driver in his ambitious "New American University" project.Last October, ASU became the first large institution to deploy Google Apps, a comprehensive suite of productivity applications that includes e-mail, search, calendars, instant messaging, and even word processing and spreadsheets.I've tried them out, they work, nothing fancy but certainly good enough for college homework assignments.
Already 40,000 students and faculty have switched their e-mail to Google, while keeping their asu.edu designation. (out of 65,000 student population, which Mr. Crow is trying to raise to 90,000 students!)
E-mail is a thorn in the side of storage administrators. Being "semi-structured" repositories, they cannot just delete or move files around, as there is context between notes and their attachments, that shouldn't be broken. E-mail systems are often the fastest growing consumer of storage for many organizations.
Switching from maintaining their own mail servers to Google is saving ASU $500,000 US dollars alone, not including the administrator labor savings. Again, some corporations might feel their e-mail is too "secret" to be outsourced like this, but for college students who spend all their creative talent posting things on MySpace and YouTube, and faculty who spend their careers TRYING to get published, they have nothing to hide from the rest of the world. It makes perfect sense.
Best of all, Google isn't charging ASU anything for this service. Google is able to cover the costs from advertising revenue instead. I can think of a lot of companies that might want to advertise to a demographic of "40,000 students who are mostly 18-25 years old and all live in or near Tempe, AZ".
In the list ofTop 10 Best Presentations Ever is Seth Godin talking about Marketing at Google. The video is worth watching.

It's good to see IBM TotalStorage Productivity Center
evolve and expand. I was the lead architect for this product a few years ago, and my has it come a long way from its early beginnings.
Today, Gartner, Inc. has IBM Positioned in Leader Quadrant for Storage Resource Management and SAN Management Software.
The Magic Quadrant is copyrighted concept by Gartner, representing a two-by-two grid that ranks various offerings from different vendors. Ideally, vendors want their products in the upper right "Leaders" quadrant. Yahoo Finance reports:
According to Gartner, Inc., "Leaders have the highest combined measures of an ability to execute and a completeness of vision. They have the most comprehensive and scalable products. They have a proven track record of financial performance and an established market presence. In terms of vision, they are perceived as thought leaders, having well-articulated plans for ease of use, how to address scalability and product breadth. For vendors to have long-term success, they must plan to address the expanded market requirements for change management and root-cause and performance analysis. Leaders must not only deliver to the current market requirements, which continue to change, but they also need to anticipate and deliver on future requirements. A cornerstone for leaders is the ability to articulate how these requirements will be addressed as part of their vision for resource management. As a group, leaders can be considered a part of most new purchase proposals, and they have high success rates in winning new business."
IBM TotalStorage Productivity Center is a strategic part of IBM Service Management
, and a foundational component of the IBM Systems Director family
. IBM is making a concerted effort across servers, networks, software and storage to help manage the IT infrastructure in a coordinated way.
I have seen other quadrants used to help explain different market segments, such as the one used in this 40-minute video Guy Kawasaki’s Art of the Start speech at TiECon 2006.
To the current architects and developers of Productivity Center, well done!

Today was our annual "State of the Site" meeting for the IBM Tucson site
. This facility was completed in 1978, and I started my career here in 1986.
Various employees and teams were recognized for the contributions and dedication. For example:
- Tom Beglin's N series team was recognized for 900% growth in IBM's NAS business.
- Jack Arnold of the Tucson Executive Briefing Center for his client advocacy.
- Michael Scott, one of my "Second Life" builder/scripters, for demonstrating client-focused dedication to IBM's corporate values.
Our site manager, Terri Mitchell, did a recap of all our recent awards and accomplishments.Of the nine Design Innovation awards won by IBM this year at the CeBIT conference, eight were for IBM System Storage products!
- The IBM System Storage EXP3000: an entry-level data storage server that is optimized for cost-sensitive and space-limited environments and employs a user-centered design that enables ease of use and simple tool-less installation and removal of all components.
- The IBM System Storage N7000 Series: a modular disk storage system that delivers high-end enterprise storage and data management value ideal for large-scale applications, while helping to anticipate growth, maintaindata availability and reduce costs.
- The IBM System Storage N5000 Series: a modular disk storage system designed to address the entire spectrum of data availability challenges while offering value in price and scalability. Built-in enterprise serviceability and manageability features support efforts to increasereliability and simplify storage infrastructure and maintenance.
- The IBM System Storage N3700: a filer that integrates storage and storage processing into a single unit, facilitating affordable network deployments.
- The IBM System Storage DS4700: a NEBS-compliant disk storage server designed to address requirements for companies in the telecommunications industry, as well as other segments, such as oil and gas, meeting standardsfor electromagnetic compatibility, thermal robustness, earthquake and office vibration resistance, and provides protection for the product components from airborne contaminants.
- The IBM System Storage EXP810: a data storage expansion unit capable of 4.8 Terabytes of physical storage, with a user-centered and tool-less design featuring redundant power, cooling, and disk modules for ease of use and simple serviceability.
- The IBM System Storage TS3400: an affordable, space-friendly tape library for users in remote locations that supports enterprise-class technology and encryption capabilities.
A representative from Tucson's Brewster Center presented Terri an award, thanking IBM for its strong support for the community through various charity initiatives.
The final speaker was a new IBM client, Tony Casella, the IT Director of the town of Marana. Recently, the town of Marana selected IBM products made big news. Arizona is the fastest growing state in the USA, and the town of Marana, just north of Tucson, is one of the fastest growing communities in Arizona. The town is growing so large that it will soon spill over from Pima into Pinal county, and will be the first town in Arizona authorized to span county boundaries.
Marana is most famous for its Gallery Golf Club on Dove Mountain that is the new home of the World Golf Championships-Accenture Match Play Championship.
His decision was based on conversations he had with other IT directors of other towns and cities, and this November 2006 article in Network World. He held up the copy of his magazine.
Tony was very delighted with IBM's solution-oriented approach, rather than just selling more boxes of hardware. He found IBM easy to do business with, and committed to his success.

Several of my IBM colleagues will be attending the "Virtual Worlds 2007" conference
today and tomorrow. This conference sold out so quickly that they have already scheduled a second one for October. The focus is on 3-D internet technologies likeSecond Life
. Attendance is expected at over 600 people.
IBM is investing heavily in this new concept of v-business. Last year, I was one of only 325 IBMers on Second Life. Now, according to this Better than Life blog entry from Grady Booch, IBM Fellow, the number is over 4000!
Of course, the challenge for IBM, and others, is learning to market in virtual worlds. Already, my team is in-world, and we meet several times a week. Using Second Life is quickly becoming an essential business skill, like participating in conference calls, or responding to instant messages.
What does meeting in-world entail?
- Scheduling a time and a place
Finding a time that people can meet is no different than scheduling a audio or video conference call. In general, you don't have to worry about travel, but you do have to be actively somewhere connected to everyone else.
Finding a place involves actually determining the island, region and coordinates to hold the meeting. You need to find a place with enough seating. You don't have to worry about daylight, each person can control how much or little sunlight shows up on their screen. You do have to make sure you pick a spot that nobody else plans to use at that same time. Just like scheduling conference rooms at the site or hotel, we have to schedule rooms in advance.
To avoid this hassle, I have created the "pocket conference room". This is a single object that I can "rez" onto the ground, from my inventory, with 40 chairs, a PowerPoint presentation screen, a podium for a speaker to stand behind, and stools for speakers to sit on if they are next on the agenda. Now, I can hold impromptu meetings in any sandbox, grassy knoll, or the roof top of a building.
- Ground Rules
As with any other meeting, you need some basic ground rules. I am not talking the usual "no shooting, no gambling, no selling" rules that you see everywhere in Second Life. Instead, rules like an avatar must stand up before speaking. Anyone with a question must first "raise their hand" and get recognized by the chair. These ground rules can be as formal as Robert's Rules of Order or more casual, depending on who is participating.
It costs 10 Linden Dollars (L$) per PAGE to upload a PowerPoint presentation. This has the immediate benefit of having everyone spend more time and effort on their presentation, trying to cut down the number of charts, and focus more on what they are going to say.
- Public Speaking Skills
It is amazing. People who are too scared to speak in front of an audience in Real Life have no problem having their avatar stand in front of other avatars in Second Life. This has greatly broadened the pool of speakers to tap into.Are you a woman with a husky masculine voice? Are you a man with a high-pitched feminine voice? Now, you can create an avatar that matches your voice.
- The Audience
This turns out to be the biggest challenge. In Real Life, organizing a face-to-face meeting involves time and effort making sure the venue has everything you need, a platform, a podium, good Audio/Video system, etc. All people have to do is show up, sit in a chair and listen.
In Second Life, however, the aspects of venue are all covered, but getting people to show up is another story. People have to sign up for Second Life account, create an avatar, wear appropriate virtual clothing, figure out how to teleport near the venue, walk or fly the difference to get to the exact building and room, master the sitting-in-a-chair and hold-coffee-and-sip-occasionally process, and pay attention.
Perhaps the best part of Second Life is that if you are not paying attention, your avatar noticeably falls asleep, into a hunched-over position, what is called "afk" (short for Away From Keyboard). On the other hand, if you do need to step away from your desk, you can put your avatar in "afk" mode immediately, tell everyone why and perhaps when you'll be back, and then re-activate when you return. This is one of the best improvements over regular audio conference calls.
I suspect the need for having places in Second Life to hold meetings will become more and more in demand.At a time when real-estate sales in the US is slowing down, Coldwell Banker's Second Life efforts are ramping up. I am not making this up. Coldwell Banker is one of the nation's largest real estate brokerage firms. They are trying to bring the same "adult supervision" to virtual real-estate transactions, offering to help people buy and rent properties in Second Life.
We live in interesting times!

In case you missed it, IBMunveiled a new digital video surveillance service
yesterday. This "marks an important shift in the industry's approach to security, applying advanced analytics to video data and signaling the ability to converge physical and information technology (IT) security."
The IBM Smart Surveillance Solution is designed to provide the unique capability to carry out efficient data analysis of video sequences either in real time or from recordings. These recordings can be on disk or tape storage.
The problem with today's existing "analog" surveillance is that the analog cameras record onto traditional VHS tapes, and these are rotated through, re-written after a few hours or days. To review tapes often involves human intervention, and must be done before the VHS tapes are re-used. Many shoplifters, thieves, and other law-breakers take a chance that their actions will not be caught on tape, or that they will be long gone by the time the video is analyzed.
The IBM Smart Surveillance Solution can provide a number of advantages over traditional video solutions, including:
- Real-time alerts that can help anticipate incidents by identifying suspicious behaviors.
- Forensic capabilities are enhanced by utilizing unique indexing and attribute-based search of video events to classify objects into categories such as people and cars.
- Situational awareness of the location, identity and activity of objects in a monitored space including license plate recognition and face capture.
With real-time analytics capabilities, the new DVS service can open up a wide array of new applications that go far beyond the traditional security aspects of surveillance systems. Early adopter industries in this rapidly evolving market include retail, public sector and financial services. The retail industry estimates nearly $50 billion is lost annually to fraud, theft and administrative errors.
Once in digital format, video surveillance can be sent further, processed quicker, and stored for longer periods of time, than traditional media makes practical today.
Beyond fraud and theft, this kind of solution could also help identify bullies who makedeath threats in High School.

The terms "information" and "data" are often used interchangeably in regular usage, but for the storageindustry, there are significant differences between the two, as different as "fact" from "meaning".
For example, if you are walking down the street, and see a pole with red and white stripes, the data of red and white stripes may not have much meaning, unless you recognize the information is that you are in front of a barber shop.I thought of this when someone pointed me to theStrip Generator Tool website, which can helpyou generate various stripes for use on the tiled background of web pages. (Or if you aredesigning neckties for your Second Life avatar).
Many national flags are based on simple stripes of different colors.For example, look at the national flags of France, Russia, and the Netherlands. These consist of a red, white, and blue stripe, justin different sequence and orientation.Again, the data of these colors, the width of their lines, and the way they are placed on the flag are all data, but the information they convey is significantly more than that.One person might walk right by the flag, not knowing which country it belongs to, while anotherperson might get emotional memories of their homeland.
For those of us in the storage industry, data is just binary 1's and 0's on disk and tape media, and canbe treated like packages at the post office in brown wrapping paper. Just as post office employees don't have to know the contents to ship them to the final destination, servers and storage devices don't need to knowthe informational content of the data that they process and store.
Converting information to data is easy. Let's take an example of taking a digital photo. The photo could be a picture of you and your spouseon your last vacation trip, but you would never know that from just looking at a series of 1's and 0's. For this reason, you create photo albums, you write captions below indicating where and when the photowas taken. This additional "context" is often called "metadata" or just simply "indexing".
Both the information captured (the photo in this case) and its metadata (the caption), can be storedas 1's and 0's on storage media. These bits can be compressed, encrypted, or represented in a variety of formats.
Information is copied from one data file to another. In the traditional sense, one piece of informationcould exist in the primary production copy, as well as multiple archive or backup copies. One piece ofinformation, stored on multiple copies of data. In a sense, this is similar to genetic information storedon each human being (data copy). Richard Dawkins, author of The Selfish Gene, reminds us that genes outlive individual humans. In storage, we remind people that data outlivesthe media it is initally written to, and the information outlives the initial data copy stored.
Converting data back to information is not always as simple.Not all sequences of 1's and 0's are obvious what they represent. To display a digital photo, you need to know the format the photo is in, and have an appropriate application that can display it back to something a human person can recognize. If the bits were compressed, the application needs to handlethat, or you need to de-compress the data before handing it to the application. For encrypted data,you need to have the decryption key. The process of converting a single file of data back to information is called "rendering".
One of the big problems with keeping information for long periods of time, isthat you may not have the equipment, decryption key, or applications needed to render the data back to usable information. You've kept the data, but you can't make any sense of it, as if it went through an episode of Will it Blend?
A good example is how the current version of Microsoft Office application is unable to interpret andrender data documents that were stored in WORD 1.0 format. IBM and others have developed "rendering tools" that can help decipher the bits, and bring back the information. To help address this challenge, the new Microsoft Office 2007 haschosen the OOXML format, but will continue to support some of the older legacy formats. IBM and the rest of the world are focused instead on Open Document Format (ODF) open standard. Those of usstill using older versions of Microsoft Office might need the Office 2007 Compatibility Pack.
Another way to get information from data is "data mining", an important part of "business intelligence". Here you are gleaning information notfrom individual details, but from patterns in the data, averages, statistics, totals, that havebroader meaning than individual transactions or events.
The distinction between "information" and "data" can be important when comparing solutions for Information Lifecycle Management (ILM) to those forData Lifecycle Management (DLM).
For many applications, DLM is just fine. Let's consider e-mail, for example. For most employees,deleting e-mails larger than 1 MB, after 90 days, regardless of content, is probably a reasonable DLM policy. All data is treated the same, based purely on the size and date markings on the outer brown wrapper.
For more sensitive content, DLM is not enough. The e-mails that are to or from the president of thecompany, or between top executives, or that contain certain pieces of information relevant for lawsuitsor other investigations, may not be treatedthe same as other e-mails. In this case, you need ILM technologies, managing based on the informational content of the data, and not just the size and date last referenced.
Of course, IBM supports both, and can help you decide the right solution for each workload.

Today,Apple and EMI announced
that EMI’s entire music and video catalog will be available in May without any digital rights management (DRM) protection.Not only with the music be higher quality, but can be played on any player, presumably using MP3 format instead ofApple's proprietary AAC format. Being locked into any single vendor solution is undesirable. Similar issues abound for Microsoft Office 2007
On my iPod, I ripped all my CDs into MP3 format, not AAC. I love my iPod, but if I ever decided to chose a different MP3 player, I did not want to go through the time-consuming process or re-ripping them again.
A blog by Seth Godin feels this Apple-EMI announcement means thatDRM is dead.
Back when music labels added value by producing and distributing music in physical form, it made sense for them to take a cut. Mass-producing CDs and distributing them out to music stores across the country costs lots of money. However, for online music, music labels don't have these same overhead costs, but continue the process of paying the artists only a few pennies per dollar. Some artists have file lawsuits to get their fair share.
This process applies to any published work. For example, you can purchase Kevin Kelly's book in various formats, at different prices, from different distributors. For example:
- In PDF for $2, directly from the author via PayPal
- black-and-white hardcover, for $20, from Amazon
- color softcopy, for $30, from Lulu
Each nets the author $1.50 in royalties per copy. You can decide how much in production and distribution costs you want to pay.
It's good to have choices again.

The "corporate bloggers" from the various storage vendors often mention their opinions about IBM products. Sometimes, they say something nice, and other times they poke fun. It's good to read the various opinions. Most are well-thought and well-written.
EMC blogger Chuck Hollis has a post about the various categories that industry analyst IDC used for external controller-based disk in their most recentQ4 Storage Scorecard.I agree with Chuck that it is good to have independent analysts that take an objective look across all storage vendors to provide the facts on various makes and models. Both IBM and EMC took marketshare in 4Q, so we cancongratulate ourselves and each other for the efforts needed to make this happen.
Chuck mentions that while EMC and HDS high-end boxes are similar, perhaps IBM's "DS" series is different enough to question putting it in the same "high-end" category. It's not clear if Chuck is poking fun at the fact that theIBM DS family spans multiple categories; or an admission thatthe IBM DS8300 Turbo is faster than the EMC DMX-3 and HDS USP offerings. Perhaps we need a new categorycalled "super high-end"?
IDC doesn't publish their data by price band, but we can infer from the products in each how they decidedwhich products were grouped into which categories. Let's examine the entire IBM DS family in the various categories.
- Entry Level
Our newest offering is the IBM System Storage DS3000 series. Some analysts call this category "low end", but IBM prefers using "entry level". These have an attractivelow acquisition price, very easy to set up, and are intended for the Intel and AMD servers, such as IBMBladeCenter, System x, as well as servers from HP and Dell. Disk arrays in this category typically have listprices below $50,000 USD.
Our midrange offering is the IBM System Storage DS4000 series. These are designed for Linux, UNIX and Windows based workloads.Some call these server platforms "open systems", or sometimes "distributed systems". The DS4000 systems are rack-optimized modularunits, providing plenty of options and trade-offs between price and performance for price-sensitive customers.The "high end" model of the DS4000 series is the DS4800, and has very impressive performance characteristics.Disk arrays in this category typically have list prices in the $50,000 to $299,000 USD range.
- Enterprise Class
IBM System Storage DS6000 seriesis one of our enterprise class offerings. DS6000 offers mainframe attachment comparable to what EMC DMX or HDS USP offer for their "enterprise class" or "high end" models, but uses substantially less power and in a much more compact modular rack-optimized packaging. Disk arrays in this category typically have list prices at $300,000 USD and above.
- Super High End
Perhaps IBM and EMC can work together to petition IDC to adopt this as a new category, based on performance,rather than list price. Is the storage marketplace ready for a fourth category?As Chuck mentioned on his blog, IBM is #1 for mainframe disk storage, and perhaps it is because the IBM System Storage DS8000 Turbo series does so well on most mainframe workloads. No offering from EMC or HDS meet or beat the SPC benchmarks for the DS8000 Turbo. You can see the results in the Executive Summary or read the Full Report.
Thanks to IBM's innovative Adaptive ReplacementCache algorithm, IBM DS8000 performance shines best handling read-intensive random-access workloads that mainframes do most often. These types of workload are modeled by the SPC-1 benchmark. In cases of write-intensive, sequential processing, the differences are less substantial, as disk arrays from all manufacturers drop down to the native performance capabilities of the 10K and 15K RPM drives.
I'll give you a real example. Not long ago, I waspart of a team to help resolve a performance bottleneck on-site at the customer location. The customer had an interesting "composite application" where data was processed on AIX platform (IBM System p), which passed the data to a Linux partition running on the IBM System z mainframe,which in turn used Java SQL to post updates to a DB2 database on z/OS partition, which then wrote out through FICON adapters to an HDS USP device. IBM and HDS worked together to help the customer figure out why they weregetting disappointing throughput and response times. IBM brought in experts on AIX, TCP/IP, Java, Linux, z/OS and FICON. HDS had their experts too, and tried to improve performance by quadrupling the storage capacity, and spreading the data out across more spindles. That didn't work. As it turns out, HDS disk just couldn't deliver the performance required. The software and mainframe were all well tuned. They replaced the HDS withan IBM DS8000 array, and it met all the service level requirements. Problem solved.
The problem with having this new "super high end" category, of course, is that only IBM plays in it, so it wouldn'toffer the marketplace much of a comparison. For now, we'll just have to settle for being the fastest in the samecategory as EMC DMX and HDS USP.
Storage is a competitive marketplace.Both EMC and HDS are reputable companies that make quality products that attach to IBM System z mainframe servers. Not all workloads are mission-critical or performance-sensitive. For less critical workloads, perhaps you may find EMC or HDS performance is "good enough".
But if performance is important to you, you should consider IBM on your list of vendors for your next purchase decision. Let IBM help you prove it to yourself, running your specific workloads side by side with your existing equipment.

Today I'm sitting in an airport, delayed due to weather.
Dick Benton of Glasshouse Technologies has an article on SearchStorage.com titled Justifying your storage staffing.
The concept that there should be a linear "Storage Administrators per TB" rule-of-thumb has been around for a while.Back in 1992, I went to visit a customer in Germany who had FIVE storage admins for 90 GB (yes, GB, not TB) disk array.I told them they only needed 3 admins, but they cited German laws that prohibited "overtime" work on evenings and weekends.
Later, in 1996, I visited an insurance company in Ohio to talk about IBM Tivoli Storage Manager. They had TWO admins to manage 7TB on their mainframe, and another 45 people managing the 7TB across their distributed systems running Linux, UNIX, and Windows. My first question, why TWO? Only one would be needed for the mainframe, but they responded that they back each other up when one takes a 2-week vacation. My second question to the rest of the audience was... "When was the last time you guys took a 2-week vacation?"
Today, admins manage many TBs of storage. But TBs are turning out not to be a fair ruler to estimate the number of admins you need. It's a moving target, and other factors have more influence that sheer quantity of data.Let's take a look at some of those factors, which we call "the three V's":
- Variety of information types
In the beginning, there were just flat text files. In today's world, we have structured databases, semi-structured e-mail systems, hypertext documents, composite applications, audio and video formats that require streaming, and so on. Variety adds to the complexity of the environment. Different data requires different treatment, different handling, and perhaps even different storage technologies.
- Volume of data
Data on disk and tape is growing 60% year on year. It's growing on paper also. It's growing on film like photos and X-rays. The problem is not the amount, but the rate of growth. Imagine if population and traffic in your city or town increased 60% in one year, most likely people would suffer because most governments just aren't prepared for that level of growth.
- Velocity of change
Back in the 1950's and 1960's, people only had to make updates once a year, scheduling time during holidays. Now, people are making changes every month, sometimes every weekend. One customer we spoke with recently said they do about 8000 changes PER WEEKEND!
So, the key is that there is no simple rule-of-thumb. Fewer admins are need per TB on mainframe than distributed systems data. Fewer admins per TB are needed when you deploy productivity software, like IBM TotalStorage Productivity Center. Fewer admins per TB are needed when you deploy storage virtualization, like IBM SAN Volume Controller or IBM virtual tape libraries.

I hope everyone had a good weekend!
Yesterday, I went to the Bodyworlds exhibition. Here the anatomy of real human cadavers are on display, in full detail, thanks to a process calledPlastination.This was a great way to present anatomy in a 3-D visual way that can be easily understood and appreciated.I was glad to see so many children were there, although I warn parents that some sections of the exhibit maybe a bit shocking. I heard people speaking French and German, and it was great that anyone can be fascinatedby the human body, without having to read or understand English.
In the exhibit, you got to see the bones, nerves, muscles, digestive tract and other organs.Some in action poses, like swinging a baseball bat or ice skating, while others were stretched into specific poses to help emphasize one part or another.
In some cases, they would show side by side healthy and unhealthy organs, for example, the lungs of someone that smokes tobacco cigarettes, compared to the lungs of a normal person. Quite a difference!
Visualization can be an effective way to understand and gain insight from information. Presenting information in a visually stunning manner can be challenging, but often worth the effort. It reminded me of Edward Tufte, who has written several books on this subject.

Last year in Beijing, China, one of my colleagues told me "When it rains here, cabs dry up". Normally, there are enough taxi cabs to handle normal conditions, but when it rains, people who normally walk now want to take a cab instead, and the demand goes up, resulting in being more difficult to find one when you need one.
I'm wrapping up my week here in Chicago, and it snowed yesterday. Cabs were scarce. I walked. Many others walked too, about half with umbrellas to protect themselves against the snowflakes.
Most systems are designed to handle typical average conditions. Taxi cabs in a city, for example, handle typicalamounts of traffic.
IT is different. In many cases, IT infrastructures are designed for the peaks, not the averages. Peaks can be where you need performance the most, and failure to design for peaks can be disastrous. As with any business decision, this represents a trade-off. Design for the average, and suffer through the peaks, or design for the peak, and be over-allocated and under-utilized most of the time otherwise.
The choice is yours.
