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.

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]
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.

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]

The "50 Years of Disk Systems Innovation" has been extended to Latin America.Pages translated into Spanish and Brazillian Portuguese are now available for the following countries:
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]
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]
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.

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]
