Continuing my week in Chicago for the IBM Storage and Storage Networking Symposium and System x and BladeCenter Technical Conference, I presented a variety of topics.
I am glad that I was able to make all of my presentations at the beginning of the week, so that I can then sit back and enjoy the rest of the sessions as a pure attendee.

Wrapping up this week's theme on why the System z10 EC mainframe can replace so many older, smal
My colleagues in IBM Poug "From Microsoft to IBM, Compaq to Sun to DEC, virtually every large computer company now uses clustering as a key strategy for high-availability, high-performance computing. This book tells you why-and how. It cuts through the marketing hype and techno-religious wars surrounding parallel processing, delivering the practical information you need to purchase, market, plan or design servers and other high-performance computing systems. "In these days of shortened fiscal horizons and contracted time-to-market schedules, traditional approaches to capacity planning are often seen by management as tending to inflate their production schedules. Rather than giving up in the face of this kind of relentless pressure to get things done faster, Guerrilla Capacity Planning facilitates rapid forecasting of capacity requirements based on the opportunistic use of whatever performance data and tools are available in such a way that management insight is expanded but their schedules are not." Neil Gunther points out that vendor claims of near linear scaling are not to be trusted and shows a method to “derate” scaling claims. His suggested scaling values for data base servers is closer IBM's LSPR-like scaling model, than TPC-C or SPEC scaling. I had mentioned that "While a 1-way z10 EC can handle 920 MIPS, the 64-way can only handle 30,657 MIPS."in my post, but still people felt I was using "linear scaling". Linear scaling would mean that if a 1Ghz single-core AMD Opteron can do four(4) MIPS, and an one-way z10 EC can do 920 MIPS, than one might assume that 1GHz dual-core AMD could do eight(8) MIPS, and the largest 64-way z10 EC can do theoretically 64 x 920 = 58,880 MIPS. The reality is closer to 6.866 and 30,657 MIPS, respectively. This was never an IBM-vs-Sun debate. One could easily make the same argument that a large Sun or HP system could replace a bunch of small 2-way x86 servers from Dell. Both types of servers have their place and purpose, and IBMsells both to meet the different needs of our clients. The savings are in total cost of ownership, reducing powerand cooling costs, floorspace, software licenses, administration costs, and outages. I hope we covered enough information so that Jeff can go back about talking about Sun products, and I can go backto talk about IBM storage products.

Over the past year and a half, I have been focused on explaining WHAT IBM System Storage was, and WHY IBM should be considered when making a storage purchase decision. Let's recapsome of IBM's accomplishments during this time:
Today, October 1, I switch over to HOW to get it done. In my new job role, I will be leading a seriesof projects and workshops on how to make your data center more green, how to get more value from the information you have, how to better protect your information from unauthorized access or unethical tampering, how to develop and deploya site-wide business continuity plan, and how to centralize your management using open industry standards.
I will still be in Tucson, but am moving from building 9032 over to 9070 to be closer to the rest of my team.
If you are interested in participating in such a workshop, contact theTucson Executive Briefing Center.

Well, this has been an interesting two weeks. On week 1, I focused on IBM's strategy and four keysolutions areas: Information Availability, Information Security, Information Retention, and Info
While IBM had switched over to solution-selling a while ago, some of our competitors are still inproduct-selling mode, and try to frame all competitive comparisons on a product-by-product basis.In my post[Supermarkets and Specialty Shops], I drew the analogy that the IT supermarkets (IBM, HP, Sun and Dell) are focusedon selling solutions, but the IT specialty shops (HDS, EMC, and others) are still focused on products.
Certainly, the transition from product-focused to solution-focused is not an easy one. As the IT industry matures, more and more clients are looking to buy solutions from theirvendors. What does it take to change behaviour of newly acquired employees, recently hired sales reps, and business partners, many of whom come from product-centric cultures, to match this dramatic shift in the marketplace? Let's take a look at change in other areas of the world.
On the[Freakonomics blog], Stephen Dubner discusses how clever people in Israel have figured out a way to get people to clean up after their pets in public places. This is a problem in many countries. Here we see an old idea, the [carrot-and-stick] approach, combined with newinformation technology. Here's an excerpt:
"In order to keep a city’s streets clean of dog poop, require dog owners to submit DNA samples from their pets when they get licenses; then use that DNA database to trace any left-behind poop and send the dogs’ owners stiff fines.
Sometimes, if enough people change, then changing behaviours of the few remaining becomes much easier. DanLockton on his Architectures of Control blog posts about the[London Design Festival - Greengaged]. This year, the festival focused on behavior changes for a greener environment, ecodesign and sustainable issues in design.Here's an excerpt and corresponding 5-minute YouTube video:
Lea argued three important points relevant to behaviour change:
Of course, tax and government regulations can heavily influence behaviour and decisions. Since today is[International Talk Like a Pirate Day], I thought I would finish this post off with this interesting piece on Google barges. Some companies, like IBM and Google, seem more adaptable to changing behaviour and trying out fresh new ideas.Will Runyon over on the Raised Floor blog, has a post about Google's patent for[Data center barges on the sea]:"The idea is to use waves to power the data centers, ocean water to cool them, and a moored distance of seven miles or more to avoid paying taxes."
Arrr! Now that's what I call a new way of looking at things!

I'm back from South America, and am now in Chicago, Illinois. I'm having breakfast at the Starbucksdowntown, and thought I would make a post before all of my meetings today.
On this trip, I met with IBM Business Partners and sales reps from Argentina, Colombia, Ecuador and Venezuela. While I have visited thefirst three countries on past trips, this was my first time to Caracas, Venezuela. I grew up in La Paz, Bolivia, and speak Spanish fluently, so had no problemgetting around and holding discussions with everyone. While my friends in the US are oftensurprised I speak multiple languages, it doesn't surprise anyone I visit in other countries.If you are going to have worldwide job responsibilities for a global company that does businessin over 180 countries, the least you could do is learn a few additional languages. I suspect themajority of the 350,000 IBM employees speak at least two languages, the exceptions being mostly the 50,000 orso employees that live in the United States.
I flew on American Airlines from Tucson to Dallas to Caracas, and was only slightly delayed as a resultof all of the flight cancellations that happened earlier that week. Some companies designate a single "official airline" for their employees to use. That makessense if all of your employees are located in a single city, and that city is the hub for yourdesignated airline.IBM is too big, too spread out, and sells technology to nearly every airline to make sucha designation. Instead, IBM tries to spread its business out to multiple carriers, although all ofmy colleagues seems to have their own personal favorites. Mine are American Airlines, Singapore Airlines and Cathay Pacific.
While other people were upset over the delays, I found American Airlines did a great job keeping me informed,and all their employees I talked to seemed to be handling the situation fairly well. If youfly on American, I recommend you sign up for "text message" notifications. I did this for everyleg of my trip, and was kept up to date on times, gates and status. Very helpful!American Airlines even started their own corporate blog: [AA Conversation] (Special thanks to my friend[Paul Gillen] for pointing this out)
(I read somewhere that if you are going to travel anywhere, you need to remember to bringboth your sunscreen and your sense of humor, otherwise you are going to get burned. Goodadvice! Trust me, you don't even know how bad it can really be until you travel in the third world.)
Anyhoo, last week, IBM Venezuela celebrated its 70th anniversary. That's right, IBM has been doingbusiness in Venezuela for the past 70 years. Also last week, IBM put out its impressive [1Q08 quarterly results],including 10 percent growth for IBM System Storage product line worldwide, comparing what IBM earned this first quarter to what IBM earned the first quarter of last year. For just the Latin American countries,the growth for IBM System Storage was 20 percent!There are a lot of oil and gas companies in Venezuela. With a barrel of oil selling at more than$117 US dollars, these companies are looking to spend their newly earned profits on IBM systems, software and services.
As for the picture above, that is a one-thousand Bolivares coin, worth about 47 US cents atthis week's official exchange rate. As with many Latin American countries going through [years of high inflation], Venezuela was tired of all those zeros on their money. For example, a cheeseburger, freedom fries and a Cokeat McDonald's would set you back 20,000 Bolivares.This year the Venezuelan governmentcreated a new currency called "Bolivares Fuertes" (VEF), lopping off the last three zeros.So, the coin above would be replaced by a new coin with a big "1" on it instead, and an old 2000 Bolivares billwould be replaced by a new 2 Bolivares Fuertes bill. Unfortunately,I had to give all my new Venezuelan money back at the airport upon leaving, but they let me keep the coinabove, since it is old money, as a souvenir so that I could use it as a ball mark for playing golf.
(The term Bolivares is named after Simon Bolivar who was born in Caracas. He is famous throughoutSouth America, and was, and I am not making this up, the first president of Colombia, the secondpresident of Venezuela, the first president of Bolivia, and the sixth president of Peru. Here isthe [Wikipedia article] to learn more.)
Gasoline costs a mere 100 old Bolivares per liter.For those who don't do metric, gasoline therefore costsless than 18 cents per gallon. By comparison, in the USA, the average today was $3.47 US dollarsper gallon, of which 18.4 cents of this is Federal tax. That's right, we pay more just in taxes forgasoline than los venezolanos pay for it all.
The side effect of cheap gas is bad traffic. Everybody in Venezuela drives their own car, and nobody thinksabout the price of gasoline, carpooling, or taking public transportation, acting much like Americans used to, up until a few years ago. With some of the gridlock we faced, it might have been faster (but not safer)to walk there instead.
Which makes me wonder if American Airlines fills up their airplanes with fuel at these lower prices when theypick up people in Caracas to take them back to the United States. In 2002, fuel represented 10 percentof the average airline's operating expenses, but today it is now 25 percent. That is a drastic increase!
The same is happening in data centers. In the past, electricity was so cheap, and such a small percentof the total IT budget, nobody gave it much thought. But as the usage of electricity increased, andthe cost per KWh went up, this has a multiplying effect, and the growth in power and cooling costs isgrowing four times faster than the average IT hardware budget increase.Read More]

It's been a while since I've talked about [Second Life].
The latest post on eightbar[Spimes, Motes and Data centers]discusses IBM's use of virtual world technology to analyze data centers in three dimensions.New World Note asks[What's The Point Of 3D Data Centers?]One would think that a simple monitoring tool based on a two-dimensional floor plan would be enough to evaluate a data center.
Enter Michael Osias, IBM (a.k.a Illuminous Beltran in Second Life). Some of the leading news sites havebegun to notice some 3D data centers that he has helped pioneer. UgoTrade writes up an article aboutMichael and the media attention in [The Wizard of IBM's 3DData Centers].
Of course, in presenting these "Real Life/Second Life" (RL/SL) interactive technologies, IBM is sometimes the target of ridicule. Why? Because IBM is 10 years ahead of everyone else. So, are there aspects of a data center where 3D interfaces makes sense? I think there is.
IBM's "New Enterprise Data Center" vision recognizes that people will need to focus on the management aspectsof their IT infrastructure, and 3D virtual world technologies might be an effective way to getthe job done.Read More]

Last week, I presented IBM's strategic initiative, the IBM Information Infrastructure, which is part of IBM's New Enterprise Data Center vision. This week, I will try to get around to talking about some of theproducts that support those solutions.
There has been a lot of attention on XIV in the past few weeks, so I will start with that. Steve Duplessie, anIT industry analyst from Enterprise Strategy Group (ESG) had a post [Adaptec buys Aristos, Tom Cruise, XIV, and Logical Assumptions] with some interesting observations and some sage advice.Val Bercovici on his NetApp Exposed blog, has a post [Has Storage Swift-Blogging Finally Jumped the Shark?] which blasts EMC for their negativity.
(For those not in the USA, swift-blogging is a reference tofalse accusations and negative remarks made during the U.S. 2004 presidential election by the[Swift Boat Veterans], and ["jumping the shark"] is a reference to [a TV show that ran out of interesting and relevant topics].For movie sequels, the comparable phrase is ["nuke the fridge"] in reference to the most recent Indiana Jones' movie.)
I was going to set the record straight on a variety of misunderstandings, rumors or speculations, but I think most have been taken care of already. IBM blogger BarryW covered the fact that SVC now supports XIV storage systems, in his post[SVC and XIV],and addressed some of the FUD already. Here was my list:
Well, I am glad I could help set the record straight. Let me know what other products people you would like me to focus on next.

This week I'm in beautiful Guadalajara, Mexico teaching at our[System Storage Portfolio Top Gun class].We have all of our various routes-to-market represented here, including our direct sales force, our technicalteams, our online IBM.COM website sales, as well as IBM Business Partners.Everyone is excited over last week's IBM announcement of [4Q07 and full year 2007 results], which incl
New York Times [I.B.M. Posts Strong Preliminary Results] said "The fourth quarter usually is the best time of the year for IBM Corp., but rarely does it look this good." When the final results were posted last Thursday, Steve Lohr wrote[IBM - A Separate Reality?]. Here'san excerpt:
But what was striking in the company’s conference call on Thursday afternoon was the unhedged optimism in its outlook for 2008, given the strong whiff of recession fear elsewhere.
Trade Radar poses the question[IBM Beats -- but is itrepresentative of entire tech sector?]. Here's an excerpt:
Looking at IBM's business segments, it can be seen that they offer far more coverage of the technology space that those of the typical tech company:
Terrific performance in a terrific year - no doubt a result of its strong global model. IBM operates in 170 countries, with about 65% of its employees outside US and about 30% in Asia Pacific. For fiscal 2007, revenues from Americas grew 4% to $41.1 billion (42% of total revenue), [EMEA] grew 14% to $34.7 billion (35%of total revenue), and Asia-Pacific grew by 11% to $19.5 billion (19.7% of total revenue). IBM sees growth prospects not just in [BRIC] but also countries like Malaysia, Poland, South Africa, Peru, and Singapore.
Thus far 2008–all two weeks of it–hasn’t been a pretty for the tech industry. Worries about the economy prevail. And even companies that had relatively good things to say like Intel get clobbered. It’s ugly out there–unless you’re IBM.
I am sure there will be more write-ups and analyses on this over the next coming weeks, and others will probably waituntil more tech companies announce their results for comparison.Read More]

I'm off for two weeks of vacation.
Here's a quick round-up of things I saw this week that didn't have time to blog about:
Last week, a writer for a magazine contacted us at IBM to confirm a quote that writing a Terabyte (TB) on disk saves 50,000 trees. I explained that this was cited from UC Berkeley's famousHow Much Information? 2003 study.
I thought of this today as I read Jefferson Graham's article "How many trees did your iPhone bill kill?" in the USA Today newspaper. Apparently, new Apple iPhone users were sent AT&T billing statements that detailed their every phone call, text message or internet access. Here's a video on YouTube from Justine Ezarik that shows the absurdity of a 300-page monthly phone bill:
To be fair, the USA Today article explains that AT&T also offers "summary billing" as well as "on-line billing", but apparently neither of these are the default choice. I can understand that phone companies send out bills on paper because not everyone who has a phone has internet access, but in the case of its iPhone customers, internet access is in the palm of your hands! Since all iPhone customers have internet access, and AT&T knows which customers are using an iPhone, it would make sense for either on-line billing or summary billing to be the default choice, and let only those that hate trees explicitly request the full billing option.
Sending a box of 300 pages of printed paper is expensive, both for the sender and the recipient. This informationcould have been shipped less expensively on computer media, a single floppy diskette or CDrom for example. Forthose who prefer getting this level of detail, a searchable digitized version might be more useful to the consumer.
Which brings me to the concept of Information Lifecycle Management (ILM). You can read my recent posts on ILM byclicking the Lifecycle tab on the right panel, or my now infamous post from last year about ILM for my iPod.
His recollection of the history and evolution of ILM fairly matches mine:
While the SNIA definition provides a vendor-independent platform to start the conversation, it can be intimidatingto some, and is difficult to memorize word for word.When I am briefing clients, especially high-level executives, they often ask for ILM to be explained in simpler terms. My simplified version is:
So ILM is not just a good idea to save a company money, it can keep them out of the court room, as well as help save the environment and not kill so many trees. Now that 100 percent of iPhone customers have internet access, and a goodnumber of non-iPhone customers have internet access at home, work, school or public library, it makes sense for companies to ask people to "opt-in" to getting their statements on paper, rather than forcing them to "opt-out".

I am proud to announce that fellow IBMer Carlos Pratt has launched a new IBM storage blog[GreenSpeed].
I'd like to expand a bit on how I know Carlos. Back in 1999 I was asked to lead a team at IBM Tucson to install Linux on our local z800 mainframe, and run tests to confirm that all of our IBM disk and tape storage offerings attached successfully. I was, at the time, lead architect for DFSMS on OS/390 and management felt that my knowledge of the S/390 instruction set was all that was needed to pull this off. My team was a collection of people from a variety of other hardware and software teams, and Carlos came over from the Disk Performance test team.
Needless to say, there were some challenges. The port of Red Hat and SUSE Linux over to the mainframe required special device drivers, and in some cases, we actually needed to make changes to the Linux kernel. While it was over 100 degrees outside, we were in the test lab wearing jackets with a refrigerator thermometer hanging on the wall to monitor our ice cold working conditions.
And of course, we had our internal skeptics. At the time, Linux was only a few percentage points of marketshare, and a few unenlightened souls did not see any reason to invest in support for a new operating system until it was more established. People with a "Wait-and-See" attitude don't last long at IBM. Fortunately, smarter heads prevailed, and now that Linux is well established as the operating system of the future, we can all look back and say "I told you so!"
Carlos was a "get things done" kind of guy. Working with frequent patches to the Linux kernel, device drivers under development, and a team fairly new to this new operating system, Carlos was able to provide the driving force to get our tests done.
So, please check out Carlos' new blog!Read More]

Last year, I started my post[Hu Yoshida should know better] with:
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 and vendor lock-in.
HDS is a major vendor for disk storage virtualization, and Hu Yoshida has been around for a while, so I felt it was fair to disagree with some of the generalizations he made to set the record straight. He's been more careful ever since.
However, his latest post [The Greening of IT: Oxymoron or Journey to a New Reality] mentions an expert panel at SNW that includedMark O’Gara Vice President of Infrastructure Management at Highmark. I was not at the SNW conference last week in Orlando, so I will just give the excerpt from Hu's account of what happened:
"Later I had the opportunity to have lunch with Mark O’Gara. Mark is a West Point graduate so he takes a very disciplined approach to addressing the greening of IT. He emphasized the need for measurements and setting targets. When he started out he did an analysis of power consumption based on vendor specifications and came up with a number of 513 KW for his data center infrastructure....
Obviously, I know better than to sip coffee whenever reading Hu's blog. I am down here in South America this week, the coffee is very hot and very delicious, so I am glad I didn't waste any on my laptop screen this time, especially reading that last sentence!
Last month, in my post [Disk only customers going back to tape], I mentioned some statistics from the Clipper Group's whitepaper[Disk and Tape Square Off Again —Tape Remains King of the Hill with LTO-4] by analysts David Reine and Mike Kahn.
In that report, a 5-year comparison found that a repository based on SATA disk was 23 times more expensive overall, and consumed 290 times more energy, than a tape library based on LTO-4 tape technology. The analysts even considered a disk-based Virtual Tape Library (VTL). Focusing just on backups, at a 20:1 deduplication ratio, the VTL solution was still 5 times per expensive than the tape library. If you use the 25:1 ratio that Hu Yoshida mentions in his post above, that would still be 4 times more than a tape library.
I am not disputing Mark O'Gara's disciplined approach.
(Update: My apologies to Mark and his colleagues at Highmark. The above paragraph implied that Mark was using badproducts or configured them incorrectly, and was inappropriate. Mark, my full apology [here])
If you do decide to go with a Virtual Tape Library, for reasons other than energy consumption, doesn't it make sense to buy it from a vendor that understands tape systems, rather than buying it from one that focuses on disk systems? Tape system vendors like IBM, HP or Sun understand tape workloads as well as related backup and archive software, and can provide better guidance and recommendations based on years of experience. Asking advice abouttape systems, including Virtual Tape Libraries, from a disk vendor is like asking for advice on different types of bread from your butcher, or advice about various cuts of meat at the bakery.
The butchers and bakers might give you answers, but it may not be the best advice.
