My IBM colleague Marissa Benekos brought her hand-held video camera to [Storage Networking World] conference in Orlando, Florida.I am not there, as I had a conflict with another conference going on here in Tucson, so am relyingon Marissa to feed me information to blog about.
In this segment, she interviews "booth babe" David Bricker. I've known David a long time,and if you are there at the conference, tell him I sent you to visit him at the IBM booth.
Sadly, I can't be in two places at once. SNW is a great conference to attend!Read More]
Well, its Tuesday, and that means more IBM announcements!!!
Let's do a quick recap of what was announced for storage:
I'm at a Business Partner conference today, discussing these announcements and other topics, so need to go back to those festivities.

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 ...
So shine bright. Be remarkable. It is not always easy to communicate your value in a technical position to clue So, Polly Pearson from EMC, although we have never met in person, I too welcome you to the blogosphere!

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.
