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.

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.

On StorageZilla, fellow blogger Mark Twomey introduces the latest entrant from EMC to the blogosphere,in his post [Polly Pearson's blog].
Although we share the same name, with the same exact spelling, I would like be the first to point out we are not related, at least as far as I know. Basing solely from her post[Welcome to my Blog - Part 1], sheis a year younger than I am, a lot better looking, majored in communications, and is not afraid to quit acrappy job for a much better job elsewhere. I on the other hand, majored in engineering, but agree wholeheartedly not to stick in a crappy situation. There is such a skills shortage out there in the IT industry,with a cap on U.S. [H-1B visas] at a paltry [65,000 this year]. If you don't like your IT job, you should be able toquit and find another one in the IT industry you are more passionate about.
On a similar theme, over at DrunkenData, Jon Toigo's latest post asks if you are[Feeling Insecure About Your Job?]ScoreLogix’s Job Security Index has fallen in the United States, with a sharp drop specifically for IT jobs. Jon points out that while it might be easy to point out that a number went up or down, it is far more difficultto explain why it did so. He gives a good piece of career advice:
Want to keep your job? Play by the rules of the front office: demonstrate the value of what you do for the company from the standpoint of cost-savings, risk reduction and process improvement. Make yourself indispensable. If they don’t appreciate you then, you need to move on. You will always be hiding in your cubical and sweating a pink slip ...

There is a difference between improving "energy efficiency" versus reducing "power consumption".
Let's consider the average 100 watt light bulb, of which 5 watts generate the desired feature (light), and 95 percent generated as undesired waste (heat). In this case, it would be 5 percent efficient. If you delivered a new light bulb that generated 3 watts of light for only 30 watts of energy, then you would have an offering that was more energy efficient (10 percent instead of 5 percent) and use 70 percent less power (30 watts instead of 100 watts). This new "dim bulb" would not be as bright as the original, but has other desirable energy qualities.
Nearly all of the output of data center equipment results in heat.In The Raised Floor blog [It's Too Darn Hot!], Will Runyon explains how IBM researcher Bruno Michel in Zurich has developed new ways to cool chips with water shot through thousands of nozzles, much like capillaries in the human body. This is just one of many developments that are part of IBM's [Project Big Green]
But what if the desired feature is heat, and the undesired feature is light?In the case of Hasbro's toy[Easy-Bake Oven],a 100W incadescent light bulb is used to bake small cakes. This is generating 95W of desired heat, and onlywasting 5 percent as light (unused inside the oven). That makes this little toy 95 percent energy efficient, butconsumes as much energy as any other 100W light bulb lamp or fixture in your house. With manufacturing switchingfrom incadescent to compact flourescent bulbs, this toy oven may not be around much longer.
While we all joke that it is just a matter of time before our employers make us ride stationary bicycles attached to generators to power our monstrous data centers, 23-year old student Daniel Sheridan designeda see-saw for kids in Africa to play on that generates electricity for nearby schools. [Dan won the "mostinnovative product" at the Enterprise Festival].
Another approach is to improve efficiency by converting previously undesirable outcomes to desirable. Brian Bergstein has a piece in Forbes titled["Heat From Data Center to Warm a Pool"].Here's an excerpt:
"In a few cases, the heat produced by the computers is used to warm nearby offices. In what appears to be a first, the town pool in Uitikon, Switzerland, outside Zurich, will be the beneficiary of the waste heat from a data center recently built by IBM Corp. (nyse: IBM) for GIB-Services AG.
I see a business opportunity here. Next to every data center lamenting about their power and cooling, build a state-of-the-art fitness center for the employees and nearby townspeople. Exercise on a stationary bicyclegenerating electricity, while your kids play on the see-saw generating electricity, and then afterwards thewhole family can take a dip in the heated swimming pool. And if the company subscribes to the notion of a Results-Oriented Work Environment [ROWE],it could encourage its employees to take "fitness" breaks throughout the day, rather than having everyone there in the early morning or late evening hours, leveling out the energy generated.
Laugh now, but this could actually work!

I've talked to several customers who have taken up the bad habit of keeping their backup copiesfor several years for "compliance reasons".
In my post last year [Lost In Translation], I talked about the different meanings of archive:
In explaining the word "archive" we came up with two separate Japanese words. One was "katazukeru", and the other was "shimau". If you are clearing the dinner plates from the table after your meal, for example, it could be done for two reasons. Both words mean "to put away", but the motivation that drives this activity changes the word usage. The first reason, katazukeru, is because the table is important, you need the table to be empty or less cluttered to use it for something else, perhaps play some card game, work on arts and craft, or pay your bills. The second reason, shimau, is because the plates are important, perhaps they are your best tableware, used only for holidays or special occasions only, and you don't want to risk having them broken. As it turns out, IBM supports both senses of the word archive. We offer "space management" when the space on the table, (or disk or database), is more important, so older low-access data can be moved off to less expensive disk or tape. We also offer "data retention" where the data itself is valuable, and must be kept on WORM or non-erasable, non-rewriteable storage to meet business or government regulatory compliance.
The process of archiving your data from primary disk to alternate storage media can satisfy both motivations.
IBM offers software specifically to help with this archival process.For email archive, IBM offers [IBM CommonStore] for Lotus Domino and MicrosoftExchange. For database archive, including support for various ERP and CRM applications, IBM offers [IBM Optim] from the acquisition of Princeton Softech.
The problems occur when companies, under the excuse of simplification or consolidation, feel they can just usetheir backups as archives. They are taking daily backups of their email repositories and databases, and keepingthese for seven to ten years. But what happens when their legal e-discovery team needs to find all emails or database records related to a particular situation, an employee, client or account? Good luck! Most backupsare not indexed for this purpose, so storage admins are stuck restoring many different backups to temporary storage and combing through the files in hopes to find the right data.
Backups are intended for operational recovery of data that is lost or corrupted as a result of hardware failures, application defects, or human error. Disk mirroring or remote replication might help with hardware failures, but any logical deletion or corruption of data is immediately duplicated, so it is not a complete solution. FlashCopy or Snapshot point-in-time copies are useful to go back a short time to recover from logical failures, but since they are usually on the same hardware as the original copies, may not protect against hardware failures. And then there's tape, and while many people malign tape as a backup storage choice, 71 percent of customers send backups to tape, according to a 2007 Forrester Research report.
Backups often aren't viable unless restored to the same hardware platform, with the same operating system and application software to make sense of the ones and zeros. For this reason, people typically only keep two to five backup versions, for no more than 30 days, to support operational recovery scenarios. If you make updatesto your hardware, OS or application software, be sure to remember to take fresh new backups, as the old backupsmay no longer apply.
Archives are different. Often, these are copies that have been "hardened" or "fossilized" so that they make sense even if the original hardware, OS or application software is unavailable. They might be indexed so that they can be searched, so that you only have to retrieve exactly the data you are looking for. Finally, they are often stored with "rendering tools" that are able to display the data using your standard web browser, eliminating the need to have a fully working application environment.
Take any backup you might have from five years ago and try to retrieve the information. Can you do it? This might be a real eye-opener.

Well, today is April 1, and I just love [April Fools' Day].This day has a rich history of practical jokes. Those not familiar can review this list of [Top 100 pranks and hoaxes].
Tim Ferris started the festivities with [The Grand Illusion: The Real Tim Ferriss speaks]. He claimed that for the past year, he outsourced the writing of his blog to a writer from India, and an editor from the Philippines. Given that his post was dated March 31, and he writes frequently about the benefits of outsourcing, it appeared like a legitimate post. However, Tim fessed up the following day, claiming that it was April 1 in Japan where he wrote it.
Guy Kawasaki wrote[April Fools' Stories You Shouldn't Believe]including my favorite #12 "Ruby on Rails cited Twitter as the centerpiece of its new 'Rails Can Scale' marketing program." Speaking of Twitter, Fellow IBM blogger Alan Lepofsky from our Lotus Notes team wrote[Great, now there is Twitter Spam]. It looked like a real post, but then I realized, ... everything on Twitter is spam!
Topics like energy consumption and global warming were fodder for posts and pranks.The post[Was Earth Hour a joke again?], argued thatthe preparation of "Earth Hour" last week in effect used up more energy than the hour of this annual "lights-off event" actually saved. This reminded me of John Tierney's piece in the New York Times ["How virtuous is Ed Begley, Jr.?"] where a scientist explains that it is more "green" for the environment to drive a car short distances than to walk:
If you walk 1.5 miles, Mr. Goodall calculates, and replace those calories by drinking about a cup of milk, the greenhouse emissions connected with that milk (like methane from the dairy farm and carbon dioxide from the delivery truck) are just about equal to the emissions from a typical car making the same trip. And if there were two of you making the trip, then the car would definitely be the more planet-friendly way to go.
Wayan Vota, my buddy over at OLPCnews, writes in his post[Windows XO Child Centric Development] that the "Sugar" operating environment on the innovative Linux-based XO laptops will soon be re-named the"Windows XO Operating System", with their new motto "Windows XO: A Child-Centric Operating Platform for Learning, Expression and Exploration." The mocked up photo of an XO laptop with the Windows XO logo was excellent!
Gretchen Rubin reminds us that this is a great day to play tricks on your kids in[How April Fool’s day can be a source of happiness], and last week, Kai Ryssdal on NPR Radio investigated if [Mind Habits] was [a video game that's good for you?]This claims that just playing five minutes per day can reduce stress. I haven't been able to stop playing after five minutes, Mind Habits is like the proverbial potato chip, you can't just eat one!
The economists from Freakonomics explain in [And While You're at it, Toss the Nickel] that it costs the US Government 1.7 cents to produce each penny. The US government loses $50 million dollars each year making pennies. Each nickel costs 10 cents to produce. This one was dated March 31, so it could actually be true. Sad, but true.
My favorite, however, was EMC blogger Barry Burke's post["5773 > c"] explaining howtheir scientists were able to reduce latency on the EMC SRDF disk replication capability:
What the de-dupe team found is that there is a hidden feature within recent generations of this chip that allow a single bit, under certain circumstances, to represent TWO bits of information.Again, this looked real, until I did the math. Start with the speed of light in a vacuum of space ("c" in BarryB's title) which is roughly 300,000 kilometers per second, or put into more understandable units, 300 kilometers per millisecond. However, light travels slower through all other materials, and for fiber optic glass it is only 200 kilometers per millisecond. Sending a block of data across 100km, and then getting a response back that it arrived safely, is a total round-trip distance of 200km, so roughly 1 millisecond. However, EMC SRDF often takes two or three round-trips per write, versus IBM Metro Mirror on the IBM System Storage DS8000 which has got this down to a single round-trip. The number of round-trips has a much bigger effect on latency than EMC's double-bit data compression technique. With IBM, you only experience about 1 millisecond latency per write for every 100km distance between locations, the shortest latency in the industry.
It is good that once a year, you should be skeptical of what you read in the blogosphere, and sometimes check the facts!

My father's favorite question is "What's the worst that could happen?" He is retired now, but workedat the famous [Kitt Peak National Observatory] designing some of the largesttelescopes. Designing telescopes followed well-established mechanical engineering best practices, but each design was unique,so there was always a chance that the end result would not deliver the expected results. What's the worst that can happen? For telescopes, a few billion dollars are wasted and a few years are added to the schedule. Scrap it and start over. Nothing unrecoverable for the US government with unlimited resources and patience.
Over the weekend, we discussed the lawsuit to stop CERN from potentially destroying the planet. Dennis Overbye writes about this in his New York Times article titled["Asking a Judge to Save the World, and Maybe a Whole Lot More"]. Here's an excerpt:
... the rest of the grimness on the front page today will matter a bit, though, if two men pursuing a lawsuit in federal court in Hawaii turn out to be right. They think a giant particle accelerator that will begin smashing protons together outside Geneva this summer might produce a black hole or something else that will spell the end of the Earth — and maybe the universe.
What's the worst that can happen? Scientists now agree that it is sometimes difficult to predict, and someeffects may be unrecoverable.
Unfortunately, this is not the only example of people attempting things they may not understand well enough. Theweb comic below has someone complaining they are out of disk space, and the sales rep suggests solving this with a few commands which will result in deleting all her files. Hopefully, most people reading will recognize this is meant as humor, and not actually attempt the code fragments to "see what they do".
Sadly, I often encounter clients who have a "keep forever" approach to their production data. When they are seriously out of space, they feel forced to either buy more disk storage, or start "the big Purge": deleting rows from their database tables, emails older than 90 days, or some other drastic measures. With a focus on keeping down IT budgets, I fear that thesedrastic measures are growing more common. What's the worst that could happen? You might need that data for defending yourself against a lawsuit, or need it to continue to provide service to a loyal client, or just continue normal business operations.I have visited companies where a junior administrator chose the "big Purge" option, without a full understanding ofwhat they were doing, resulting in business disruption until the data could be recovered or re-entered.
IBM offers a better way. Data that may not be needed on disk forever could be moved to lower-cost tape, using up less energy and less floorspace in your data center. Solutions can automatically delete the data systematically based on chronological or event-based retention policies, with the option to keep some data longer in response to a "legal hold" request.
That's certainly better than to risk shrinking your business into a "dense dead lump"!Read More]

I got some interesting queries about IBM's Scale-Out File Services [SoFS] that I mentioned in my post yesterday [Area rugs versus Wall-to-Wall carpeting]. I thought I would provide some additional details of the product.
SoFS combines three key features: a global namespace, a clustered file system, and Information LifecycleManagement (ILM). Let's tackle each one.
SoFS is part of IBM's [Blue Cloud] initiativethat was launched last November 2007. Of course, IBM isn't the only one competing in this space. HDS has partneredwith BlueArc, HP has acquired PolyServe, and Sun acquired CFS for their Lustre file system. Isilon and Exanet arestart-up companies with some offerings. EMC acquired Rainfinity,and have hinted at a Hulk/Maui project that they might deliver later this year or perhaps in 2009, but by thenmight be a dollar-short and a day-late.
But why wait? IBM SoFS is available today and is orders of magnitude more scalable!

As a consultant, I am often asked to help design the architecture for the information infrastructure. A usefulanalogy to gather requirements and preferences is the difference between area rugs and wall-to-wall carpeting. Arearugs are not secured to the floor and cover only a portion of the floor area. Carpets are generally tacked or cemented to the floor, often with an underlay of cushion padding, stretched across the entire floor surface, out to all four walls of each room.
Each has its pros and cons, and often is a matter of preference. Some people like area rugs because they can choosea different style for each room, match the decor and color scheme of furniture, and use these to define each livingspace. Ever since paleolithic man put animal skins on the floor of their cave, people recognize that cold, hard andugly floors could be covered up with something soft and more attractive.Others prefer wall-to-wall carpeting because they want to walk around the house barefoot, have their young children crawl on their hands and knees, and give the entire house a unified look and feel. This is often an inexpensive option when compared against the cost of individual rugs.
IBM can help you design an information infrastructure that fits either approach.Read More]
Soon, the U.S. is switching on-air television signals from analog to digital format. The switch-over happensFebruary 17, 2009. According to the [Federal Communications Commission], Americans haveuntil this Monday, March 31, to request up to two 40-dollar coupons towards the purchase of digital-to-analog converter boxesso that the on-air digital signals can be used with existing analog-only television equipment.
(For my readers outside the United States, a bit of background explanation may be necessary. Americans consider access to television a self-evident and unalienable right.According to a Pew Research report[Luxury or Necessity?] 64 percent of Americansconsider a television set a necessity, and 33 percent consider paid providers, like cable or satellite, a necessity.Even prisoners in U.S. jails are allowed to watch television!)
Taking advantage of the "Y2K crisis" like nature of this 2/17/2009 deadline, paid providers have been advertisingthat this deadline only applies to on-air customers. Those who have cable or satellite can continue to use theiranalog equipment. I have been a subscriber for Cox Cable for some time, and my parents recently made the switchas well. Two weeks ago, however, my parents called me in a panic. Cox Cable chose to move one channel, TurnerClassic Movies (TCM), over from their analog line-up over to their digital line-up. They thought this wasn't goingto happen until 2/17/2009! They asked me to investigate and provide them alternative options.
I spoke to a Cox Cable representative.
I decided to give it a try, and a technician was scheduled to perform the installation last Sunday, which was Easter holiday for some people. The technician was able to connect the set-top box directly to my television set, but thesignal is converted to a single "Channel 3", forcing the use of a separate Cox Cable remote control unit to set the channel on the set-top box. He set the set-top box to TCM (channel 199) and showed that the TCM channel was now available again.
I feel bad for the technician. He spent two hours on his Easter Sunday to install service that I was told by theirsales rep would work with my equipment, only to find out it won't and he ended up having to take it all back out andcancel the work order. He doesn't even get paid overtime for this.
So, I am back to where I was before, analog channels minus the TCM channel. However, the lesson is clear, even
Yesterday marked the first day of Spring here in the Northern hemisphere, and often this means it is timefor some "Spring cleaning". This is a great time to re-evaluate all of your stuff and clean house.
In the bits-vs-atoms discussion, Annie Leonard has a quick [20-minute video] about the atoms side of stuff,from extraction of natural resources, production, distribution, consumption, to final disposal.
On the bits side of things, the picture is much different.
Jon Toigo over at DrunkenData writes in his post[A Wink and a Nod] about thebenefits of the new IBM System z10 Enterprise Class mainframe. Here's an excerpt about storage:
"The other key point worth making about this scenario is that storage behind a z10 must conform to IBM DASD rules. That means no more BS standards wars between knuckle-draggers in the storage world who continue to mitigate the heterogeneous interoperability and manageability of distributed systems storage using proprietary lock in technologies designed as much to lock in the consumer and lock out the competition as to deliver any real value. That has got to be worth something."
For z/OS and TPF operating systems, disk must support CCW commands over ESCON or FICON connections, or NFS commandsover the Local Area Network. However, most of the workloads that are being ported over from x86 platforms willprobably be running Linux on System z images, and as such Linux supports both CCW and SCSI protocols, the latterover native FCP connections through a Storage Area Network (SAN) or via iSCSI over the Local Area Network. Many SAN directors support both FCP and FICON, and the z10 also supports both 1Gbps and 10Gbps Ethernet, so you may not have to invest in any new networking gear.
The best part is that you may not have to migrate your data. The IBM System Storage SAN Volume Controller is supported for Linux on System z, and with "image mode" you can leave the data in its original format on its original disk array. Many file systems are now supported by Linux, including Windows NTFS with the latest NTFS-3G driver.
If your data is already on NAS storage, such as the IBM System Storage N series disk systems, then the IBM z10can access it directly, from z/OS, z/VM or Linux.
Have lots of LTO tape data? Linux on System z supports LTO as well.
Jon continues his rant with a question about porting Microsoft Windows applications. Here's another excerpt:
"For one, what do we do with all the Microsoft servers. There is no Redmond-sanctioned approach to my knowledge for virtualizing Microsoft SQL Server or Exchange Server in a mainframe partition."
Yes, it is possible to run Windows on a mainframe through emulation, but I feel that's the wrong approach. Instead, the focus should be on running "functionally equivalent" programs on the native mainframe operating systems, and again Linuxis often the best choice for this. Switching from Windows to Linux may not be "Red Instead of SQL Server, consider something functionally equivalent like IBM's DB2 Universal Database, or perhaps an open source database like MySQL, PostgreSQL or Apache Derby. Well-written applications use standard SQL calls, so ifthe application does not try to use unique, proprietary features of MS SQL Server, you are in good shape. In my discussion last November on [Microsoft Exchange email server], I mentioned that Bynari makes a functionally equivalent email server on Linux that works with your existing Microsoft Outlook clients. Your end-users wouldn't know you migrated to a mainframe!

A [recent survey] conductedby Fleishman-Hillard Researchindicates that the majority of disk-only customers are now lookingat adding tape back into their infrastructure. Here are some excerpts:
"Over two thirds of surveyed businesses said they were lookingto add tape storage back into their overall network infrastructure and of those respondents, over80-percent plan to add tape storage solutions within the next 12 months.The survey, which was taken in the fourth quarter of 2007, focused on the views of morethan 200 network administrators and mid-level tech specialists at mid-size to large companiesthroughout the United States.
While disk provides online data access and availability, tape provides additional data protectionand security, lower total cost of ownership (TCO), lower energy consumption (Tape is more "green"),and can be an important part of a long term data retention and compliance strategy.
Disk is more costly, more energy hungry, and some data, although it must be retained, may seldom, if ever be looked at, so why keep it spinning?
Speaking of TCO, in a recent 5-year TCO analysis by the Clipper Group titled[“Disk and Tape Square Off Again”]stored 2.4PB of data long term on SATA disk and on an LTO tape library, the disk system was:23:1 more costly, used 290 times the amount of energy than tapeEven with a data dedupe system like IBM System Storage N series, disk was still 5 times more costly than the tape system.
The Linear Tape Open (LTO) consortium --consisting of IBM, Hewlett-Packard (HP) and Quantum-- just released its "LTO-5" plans. With 2:1 compression,you will be able to pack up to 3TB of data on a single tape cartridge. And while dollar-per-GB declinefor disk is slowing down to 25-30 percent per year, tape continues to decline at a healthy 40 percent rate, so the price gap between diskand tape will actually widen even further over the next few years.
That's something to get excited about!Read More]

Last week, I covered backup issues in [Ded
At IBM, our standard is to have a limit of 200MB per user mailbox. A few of us get exceptions and have up to500MB limit because of the work we do. By comparison, my personal Gmail account is now up to 6500MB. Whenthis limit is exceeded, you are unable to send out any mail until it is brought down below the limit, and a request to be "re-enabled for send" is approved, a situation we call "mail jail".
The biggest culprit are attachments. Only 10 percent of emails have attachments, but those that do take up 90percent of the total space! People attach a 15MB presentation or document, and copy the world ondistribution list. Everyone saves their notes with these attachments, and soon, the limits are blown. Not surprisingly, deduplication has been cited as a "killer app" to address email storage, exactly for this reason.If all the users have their mailboxes all stored on the same deduplication storage device, it might find theseduplicate blocks, and manage to reduce the space consumed.
A better practice would be to avoid this in the first place. Here are the techniques I use instead:
This all relates to new ways for employees to collaborate. Shawn from Anecdote writes in the post[Fostering a Collaboration Culture]:
"Have you invested in the latest and greatest in collaboration technology but still feel people are still not collaborating? How many Microsoft Sharepoint servers and IBM Quickplaces remain relatively untouched or only used by the organization's technorati? I think it's a big problem because this narrow view of collaboration starts to get the concept a bad name: "yeah, we did collaboration but no one used it." And then there the issue of the vast amount of money wasted and opportunities lost. We can't afford to loose faith in collaboration because the external environment is moving in a direction that mandates we collaborate. The problems we face now and into the future will only increase in complexity and it will require teams of people within and across organizations to solve them."
Well, sending pointers instead of attachments works for me, and has kept me out of "mail jail" for quite some timenow.Read More]

IDC, an independent industry analyst firm, put out their 4Q07"Worldwide Disk Storage Systems Quarterly Tracker" report. Here is an excerpts from their [press release]:
"Worldwide external disk storage systems factory revenues posted 9.8 percent year-over-year growth in the fourth quarter of 2007 (4Q07) and totaling $5.3 billion (USD), according to the IDC Worldwide Disk Storage Systems Quarterly Tracker. For the quarter, the total disk storage systems market grew to $7.5 billion (USD), up 7.6 percent from the prior year's fourth quarter. Total disk storage systems capacity shipped reach 1,645 petabytes, growing 56.3 percent."
For those wondering how an industry could grow 56.3 percent in capacity, but only 7.6 percent in revenue, it isbecause the average dollar-per-GB dropped in 2007 from $6.63 down to $4.56 (USD), representing a 31 percent decline.In the past, disk prices dropped 40 to 60 percent each year, so making single digit growth was the best major vendorscould hope for. However, lately this has slowed down to 25 to 35 percent decline, but the client demand for capacity continues at the 60 percent pace, which means that vendors could achieve double digit revenue growth soon.
Once again, IBM was ranked number 1 in total disk storage. No surprise there. Here are the details:
"Total Disk Storage Systems Market
But why focus just on disk? IDC also released their"Worldwide Combined Disk and Tape Storage 3Q07 Market Share Update", and IBM was number one for that as well,taking in 21.9 percent share. Here's a quote of IBM VP Barry Rudolph in[CNN Money]:
"IBM's continued leadership in the storage hardware market reaffirms our strategy to provide the most comprehensive tiered portfolio of storage offerings, ranging from software and services to disk and tape storage solutions," said Barry Rudolph, Vice President, Storage Stack Solutions, IBM. "IBM is the clear choice for providing information infrastructure solutions that offer the most cost-efficient, streamlined approach to help our customers increase overall productivity and maximize performance."
It is looking like 2008 is going to be a good year for IBM!

No, this is not an announcement about myself moving to Nepal.

I think this might be a great opportunity for someone to help changethe world. Those of you who have read my past blog posts about the One Laptop per Child [OLPC], such as [Understanding the LAMP platform] and [Supporting OLPC Schools with LAMP stacks] may understand the type of work involved.
I've been working with Dev, Bryan and Sulochan for the past three months (remotely here from Tucson, AZ)but we've come to a point where we need on-site expertise. I will continue to provide remote support.

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]

I am always amused in the manner the IT industry tries to solve problems. Take, for example, theprocess of backups. The simplest approach is to backup everything, and keep "n" versions of that.Simple enough for a small customer who has only a handful of machines, but does not scale well. Inmy post [Times a Million],I coined the phrase "laptop mentality", referring to people's inability to think through solutions in large scale.
Apparently, I am not alone.Steve Duplessie (ESG) wrote in his post[Random Thoughts]:
"I may even get to stop yelling at people to stop doing full backups every week on non-changing data (which is 80 %+) just because that's how they used to do it. They won't have a choice. You can't back up 5X your current data the way you do (or don't) today."
Hu Yoshida (HDS) does a great job explaining that thereare three ways to perform deduplication for backups:
Here's an excerpt from his post[Deduplication Ratios]:
"A full backup of 1TB data base tablespace is taken on day one. The next day another full backup is taken and only 2GB of that backup has any changes.
While IBM also offers deduplication in the IBM System Storage N series disk systems, I find that for backup, itis often more effective to apply best practices via IBM Tivoli Storage Manager (TSM). Let's take a look at some:
Last November, I visited a customer in Canada. All of their problems were a direct result of taking full backupsevery weekend. It put a strain on their network; it used up too many disk and tape resources; and it took too long tocomplete. They asked about virtual tape libraries, deduplication, and anything else that could help them. The answer was simple: switch to IBM Tivoli Storage Manager and apply best practices.

On Tuesday, I covered much of the Feb 26 announcements, but left the IBM System Storage DS8000 for today so that it can haveits own special focus.
Many of the enhancements relate to z/OS Global Mirror, which we formerly called eXtended Remote Copy or "XRC", not to be confused with our "regular" Global Mirror that applies to all data. For those not familiar with z/OS Global Mirror, here is how it works. The production mainframe writes updates to the DS8000, and the DS8000 keeps track of these in cache until a "reader" can pull them over to the secondary location.The "reader" is called System Data Mover (SDM) which runs in its own address space under z/OS operating system. Thanks to some work my team did several years ago, z/OS Global Mirror was able to extend beyond z/OS volumes and include Linux on System z data. Linux on System z can use a "Compatible Disk Layout" (CDL) format (now the default) that meetsall the requirements to be included in the copy session.
IBM has over 300 deployments of z/OS Global Mirror, mostly banks, brokerages and insurance companies. The feature can keep tens of thousands of volumes in one big "consistency group" and asynchronously mirror them to any distance on the planet, with the secondary copy recovery point objective (RPO) only a few seconds behind the primary.
Aside from the first item, the Extended Distance FICON, the other enhancements are "preview announcements" which means that IBM has not yet worked out the final details of price, packaging or delivery date. In many cases, the work is done, has been tested in our labs, or running beta in select client locations, but for completeness I am required to make the following disclaimer:
All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice. Availability, prices, ordering information, and terms and conditions will be provided when the product is announced for general availability.Read More]
Yesterday, I asked if you were prepared for the future? The future is now. Today, IBM announced its["New Enterprise Data Center"] vision and strategy which spans software, hardware and services in dealing withthe latest challenges that our clients are faced with today, or will face sooner or later this century.
Here's an excerpt:
Align IT with business goals
A lot was announced today, so I will give a quick recap now, and cover specific areas over the rest of the week.
