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!

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. You might have inherited this back technorati tags: IBM, backup, archive, compliance, katazukeru, shimau, space management, data retention, Forrester Research, disk, tape, FlashCopy, Snapshot, point-in-time, eye-opener, hardened, fossilized, rendering, application environment

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]
