I am flabbergasted. Befuddled. Confused. “ILM is dead” says a blog published on Computerworld a couple of days ago. Imagine such an article (a blog really) appearing in a publication that has run so many articles, advertisements, and advertorial projects extolling the virtues of ILM!
Hey Computerworld, why would you print such an article. Has the advertising dollar well around “ILM” suddenly run dry? 🙂
We have been criticizing the marketecture around ILM since this blog first opened its doors. (We coined the word “marketecture” — by the way — to describe EMC’s ILM pitch, though I didn’t see any credit given to us in Robin’s blog!) It did not require a handful of surveys from SNUG to wake us up to the fact that the “Hype Curve” on ILM would quickly move consumers into the “Trough of Disillusionment” — which is what the post says has happened.
I would be careful not to throw the baby out with the bathwater. “Information Feng Shui Management” (the industry BS around the topic) is not ILM. ILM is a good idea, something that needs to be realized. ILM SNIA-style or EMC-style is just good old fashioned nonsense designed to sell overly complex and proprietary wares. We’ve said it before and we’ll say it again: ILM is more a people/process issue than a technology issue because it begins with the user — how he creates and names files so their worth is discernable and classifiable. It also requires a storage classification scheme so you can map platform cost and performance characteristics to what data requires in terms of access, update frequency/volatility, security, etc.
The blog incorrectly asserts that ILM is just HSM. Certainly, lots of products that call themselves ILM are just HSM (if even that). To do real ILM, other stuff, besides data age (creation date, date last modified, date last accessed) needs to drive migration through infrastructure. More granular information about data and its business context is required. HSM is a blunt instrument. Trying to do data management with HSM is like using a hammer to perform open heart surgery: messy and imprecise.
The right tools for ILM haven’t appeared in the market. And tools alone won’t create a disciplined managed data environment, in any case.
ILM is dead. Long live ILM.
