I owe an apology to Mark O'Gara and his colleagues at Highmark for my post last week [Which is greener, Real or Virtual Tape?].
Last week's focus was on tape libraries, both virtual and real, leading up to our IBM announcement ofacquiring Diligent Technologies. I was focused on HDS blogger Hu Yoshida's post about his conversation with Mark,who was on an expert panel about these topics. Mark discovered that of the top energy consumersin his datacenter, his tape library was in the top five, a surprising result. Hu suggested that switching to a VTL with dedu My response was that perhaps Highmark's choice of backup software was poorly written, or that they had set it up with thewrong parameters, and just changing hardware might not be the right answer. I went too far given that I didn't know which software they had, which parameters theywere using, or which tape technology was involved. This came across wrong. I meant to poke fun at Hu's response.I did not mean to imply that Mark and his staff hadmade poor choices, or that they should automatically reject Hu's advice to consider other hardware alternatives. I have discussed the situation with Mark, and agree that I should know his situation better before offeringsuggestions of my own. Again, I'm sorry Mark.

I made it a point NOT to be in an airplane on "Earth Day" yesterday.
Today, I am posting this from the Houston Airporton my way down to Cuernavaca, Mexico to participate in the Storage Symposium 2008 Mexico, April 24-25, 2008.
We have a list of speakers presenting on various topics. I will be covering IBM's leadership in thefollowing areas:
For those interested in the USA, there will be the [IBM System Storage and Storage Networking Symposium] in San Diego, California, July 14-18, 2008. Registration opened today!
And, it's not too late to sign up for IBM Tivoli's [Pulse 2008] conference that will be heldin Orlando, Florida, May 18-22, 2008. I'll be there Sunday and Monday only, in the Tivoli Storage track, so if you are planning to attend and wish to meet up with me while I am there, please send me a note!Read More]

Happy "Earth Day 2008" everyone!
[Earth Day] is celebrated in many countries on April 22, which marks the anniversary of the birth of the modern environmental movement in 1970. Others celebrate this on the March equinox.
IBM has finally aggregated everything that we are doing around "Green" initiatives onto a single[IBM Green] landing page. This has everything from IBM's own activities as well as what we sell to our clients.
IBM also developed [Power Up, the Game], which is theEarth Day Network's "official" game for today's festivities. It's a 3-D game created by IBM Research to help save a fictitious planet - the goal being to help students learn about ecology and climate change. This game is also hoped to motivate young students to get interested in math, scienceand technology.Eightbar has a great post [PowerUp - A serious game out inthe wild] discussing this.Here's also a 3-minute[the making of "Power Up, the game" video] to geta behind-the-scenes look.The game is a downloadable Windows client that then connects to the main servers to run.
If you prefer the real world over virtual worlds, IBMer Harald Fuchs, from IBM Germany, is currently trekking across Greenland's polar ice cap.

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]
Normally, IBM only makes announcements on Tuesdays, but today, Friday, IBM announces that it acquired Diligent Technologies. What? I got a lot ofquestions about this, so I thought I would start with this...
When I posted in January that[IBM Acquires XIV],fellow EMC blogger Mark Twomey of StorageZilla fame, sent me a comment:
"Ah now Tony I wasn't poking fun. Indeed I find it fascinating that Moshe who's been sitting out on the fringes for years having been banished for being an obstructionist to EMC entering the mid-market is now back.
As you might have guessed, I am privy to a lot of stuff going on behind the scenes at IBM that I can't talk about in this blog, and all these rumors in the blogosphere about IBM acquisition of Diligent was a topic I couldn't officially recognize, defend or deny, until official IBM announcements were made.
In his latest post, Mark wonders about[the last Tape and Mainframe sales person on earth]. He recounts my interaction with fellow HDS blogger Hu Yoshia about the energy benefits ofVirtual Tape Libraries. Knowing that we were going to announcement IBM's acquisition of Diligent soon, I thoughtthis would be a worthy exchange, driving up the sales of Diligent boxes (whether you buy them from IBM or HDS).Diligent already had reselling arrangements with HDS, and IBM plans to continue thosearrangements going forward with HDS. As I have explained before in my post [Supermarketsand Specialty Shops], IBM and HDS cater to different customers, so if a customer who wants the best technologyfrom a specialty shop, they can buy IBM Diligent products from HDS, but if they want one-stop shopping, they can buyIBM Diligent directly from IBM or its other IBM Business Partners.
(Perhaps a more tricky situation is that Diligent also had an arrangement with Sun Microsystems, which competesdirectly against IBM as another IT supermarket vendor, but I have not heard how IBM has decided to handle thisgoing forward.)
For more on this intricate mess of interconnected companies, alliances and partnerships, read Dave Raffo's article[Data dedupe dance cardfilling up] over at Storage Soup.
So, let's tackle the first question:
While TSM does a good job of "deduplicating" at the client first, backing up only changed data, Scott feels database and email repositories must be backed up entirely each time, which is what happens in many other backup software products. Some clients might have 80 percent database/email and only 20 percent files, while others might have less than 20 percent database/email and 80 percent files, so this might influence whether deduplication will have small or big benefit.If TSM has to backup the entire database, even though little has changed since the last backup, that is where deduplication on a virtual tape library can come in handy. For IBM DB2 and Oracle databases, IBM TSM application-aware Tivoli Data Protection module interface backs up only changed data, not the entire file. Thanks to IBM's FilesX acquisition-- (also coincidently from Israel) --IBM can extend this support now to SQL Server databases as well.However, to be fair, Scott is partly correct, TSM does backup some database and email repositories in their entirety, which is why it is a good idea to have BOTH an IBM virtual tape library with deduplication and Tivoli Storage Manager to handle all cases. This brings us to the next question:
Jon Toigo from DrunkenData asks[Did IBM Do Due Diligence Before Making Diligent Acquisition a Done Deal?] which is probably always a valid question. Unlike XIV, I wasn't part of the Diligent acquisition team, so I can't provide first hand account of the process. I am told that the IBM team did all the right things to make sure everything is going to turn out right.Sadly, many companies that make acquisitions in the IT industry fail to make them work. Fortunately, IBM is one of the few companies that has a great success record, with over 60 acquisitions in the past six years.In the Xconomy forum, Wade Rousch writes[IBM and the Art of Acquisitions]and gives some insight why IBM is different. Jon did not understand why Cindy Grossman, IBM VP of tape and archive solutions, ran the analyst conference call for this announcement, which brings me to the next question:
Some might remember that IBM already has deduplication in its IBM N series products, called Advanced Single InstanceStorage, or A-SIS. Here is an[IBM System Storage N Series A-SIS Deduplication Deployment and Implementation Guide. This brings up the fourth question:
As with any acquisition, there will be some changes. The 100 folks from Diligent will get to learn the IBM wayof doing things. This brings me to our fifth and final question:
That's all for now, I'm off to Chicago, Illinois tomorrow!

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.

Fellow blogger and cartoon writer Scott Adams writes in his Dilbert Blog posts about the [Monte Hall problem].Monte Hall was the host of the American game show Let's Make a Deal. Here is an excerpt:
Mathematically, on your initial choice of doors, you have a 1/3 chance of picking the car, and 2/3 chance ofpicking a goat. But, after you make a choice, Monte knows which door(s) have goats behind them, and selectsone that exposes the goat. If you stay with your initial choice, you still have a 1/3 chance that you win acar, but if you change your mind and choose the other door, your odds double, you have a 2/3 chance of winning.This is not obvious at all to most people, so Scott points people to the [Wikipedia entry] that provides the math What does this have to do with storage? When you pick a disk system, you are hoping you pick the door with the car. You want a disk system that meets your performance requirements for your particular workload and easy to deploy, configure and manage, with a low total cost of ownership for the three, four or five years you plan to use it.However, with over forty different storage vendors, there are some doors that might have goats. Some vendorshave only 90 day warranties for their software, and I don't know any customers that replace their disk systems that often. It would be nice if everyone published all of their performance benchmarks so that you canchoose the right door with the car behind it, but sadly in the storage industry, not ever In other cases, people make their choices based on past decisions. Perhaps someone beforethem chose one vendor over another, and it seems simple enough just to stay with the originalchoice. It is amazing how often people stay with their company's original choice, what we call in the industry the "incumbent vendor", without exploring alternatives. So, if you bought an EMC, HDS or HP disk system in the last 90 days, it's not too late for you.Tell your local IBM rep that you are afraid you picked the door with the goat, and that you want to change your mind, and choose the other door and go with IBM instead. You will double your chances of being happier with your new choice!

Storage Networking World conference is over, and the buzz from the analysts appears to be focused onXiotech's low-cost RAID brick (LCRB) called Intelligent Storage Element, or ISE.
(Full disclosure: I work for IBM, not Xiotech, in case there weren't enough IBM references on this blog page to remindyou of that. I am writing this piece entirely from publicly available sources of information, and notfrom any internal working relationships between IBM and Xiotech. Xiotech is a member of the IBM BladeCenteralliance and our two companies collaborate together in that regard.)
Fellow blogger Jon Toigo in his DrunkenData blog posted [I’m Humming “ISE ISE Baby” this Week] and then a follow-up post[ISE Launches]. I looked up Xiotech's SPC-1benchmark numbers for the Emprise 5000 with both 73GB and 146GB drives, and at 8,202 IOPS per TB, does not seem to be as fast as IBM SAN VolumeControllers 11,354 IOPS per TB. Xiotech offers an impressive 5 year warranty (by comparison, IBM offers up to 4 years, and EMC I think is stillonly 90 days).Jon also wrote a review in [Enterprise Systems]that goes into more detail about the ISE.
Fellow blogger Robin Harris in his StorageMojo blog posted [SNW update - Xiotech’s ISE and the dilithium solution], feeling that Xiotech should win the "Best Announcement at SNW" prize. He points to the cool video on the[Xiotech website]. In that video, they claim 91,000 IOPS.Given that it took forty(40) 73GB drives (or 4 datapacs) in the previous example to get 8,202 IOPS for 1TB usable, I am guessing the 91,000 IOPS is probably 44 datapacs (440 drives) glommed together, representing 11TB usable.The ISE design appears very similar to the "data modules" used in IBM's XIV Nextra system.
Fellow blogger Mark Twomey from EMC in his StorageZilla blog posted[Xiotech: Industry second]correctly points out that Xiotech's 520-byte block (512 bytes plus extra for added integrity) was not the firstin the industry. Mark explains that EMC CLARiiON had this since the early 1990's, and implies in the title that this must have been the first in the industry, making Xiotech an industry second. Sorry Mark, both EMC and Xiotech were late to the game. IBM had been using 520-byte blocksize on its disk since 1980 with the System/38. This system morphed to the AS/400, and the blocksize was bumped up to 522 bytes in 1990, and is now called the System i, where the blocksize was bumped up yet again to 528 bytes in 2007.
While IBM was clever to do this, it actually means fewer choices for our System i clients, being only able to chooseexternal disk systems that explicitly support these non-standard blocksize values, such as the IBM System Storage DS8000and DS6000 series. (Yes, BarryB, IBM still sells the DS6000!) The DS6000 was specifically designed with the System i and smaller System z mainframes in mind, and in that niche does very well. Fortunately, as I mentioned in my February post [Getting off the island - the new i5/OS V6R1], IBM has now used virtualization, in the form of the VIOS logical partition, to allow i5/OS systems to attach to standard 512-byte block devices, greatly expanding the storage choices for our clients.
(Side note: SNW happens twice per year, so the challenge is having something new and fresh to talk about each time. While Andy Monshaw, General Manager of IBM System Storage, highlighted some of the many emerging technologies in his keynote address, IBM shipped on many of them prior to his last appearance in October 2007: thin provisioning in the IBM System Storage N series, deduplication in the IBM System Storage N series Advanced Single Instance Storage (A-SIS) feature, and Solid State Disk (SSD) drives in the IBM BladeCenter HS21-XM models. Of course, not everyone buys IBM gear the first day it is available, and IBM is not the only vendor to offer these technologies. My point is that for many people, these are still not yet deployed in their own data center, and so they are still in the future for them. However, since these IBM deliveries happened more than six months ago, they're old news in the eyes of the SNW attendees. While those who follow IBM closely would know that, others like[Britney Spears] may not.)
Back in the 1990s, when IBM was developing the IBM SAN Volume Controller (SVC), we generically called the managed disk arrays that were being virtualized by the SVC as "low-cost RAID brick" or LCRB. The IBM DS3400 is a good example of this. However, as we learned, SVC is not just for LCRB, it adds value in front of all kinds of disk systems, including the not-so-low-cost EMC DMX and IBM DS8000 disk systems. ISE might make a reasonable back-end managed disk device for IBM SVC to virtualize. This gives you the new cool features of Xiotech's ISE, with IBM SVC's faster performance, more robust functionality and advanced copy services.
Next week, I'll be in South America in meetings with IBM Business Partners and storage sales reps.
