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.
