ILM seems to be MIA, but why?

I don’t see the terms ILM or Data Lifecycle Management mentioned much anymore on the Interwebs. Odd that we have this many regulatory pressures, and the one thing that could actually save us some money, time and stress when dealing with those pressures hasn’t been seen in headlines for at least a year, maybe two.

Where did ILM go? Did it morph into something else? Based on all the coverage it was getting two years ago, you’d think we would have progressed to hardware-based products supporting ILM initiatives by now. Yet the storage hardware vendors, with the most noticeable exception being Compellent, still haven’t added ILM features to their hardware. Storage software vendors, like Veritas, IBM Tivoli, CommVault, et al., still offer ILM features for their software suites, but today it’s dedupe that has the spotlight. And I’m not so sure I see the reason why.

I understand the marketing behind dedupe: “Hard economic times are ahead, so save money and don’t buy as much disk.” But if you look at the sales figures from the leading storage vendors, they are all meeting their sales estimates, and in some cases exceeding those estimates by a good margin, so businesses apparently haven’t yet gotten into the whole “save money” or the “buy less” aspect of that marketing push.

Managing one’s data seems to me the better way to spend, if you know when to move it to cheap disk, commodity tape and through to destruction. It would free up capacity on fast expensive disk, and reduce the effort needed to satisfy policy pressures. I distinctly remember eons ago sitting in a conference hall and listening to Curtis Preston for the first time, and this topic was the thrust of his talk: Manage your data, figure out where it should live and put it there.

This message holds true now more than ever. Just think, three or four years ago, 250 GB drives were the largest SATA drives certified for storage arrays. Now, with 750 GB to 1 TB in each slot, we have even more of a need to know when the data was created and when it needs to be archived or destroyed. With SSDs rapidly making their way into storage arrays, data management and subsequent movement becomes a crucial cost saving tool.

The part about all this that baffles me the most is liability. You’d think that if you were going to be legally liable to either hold onto or destroy files or information, you’d probably want an automated, “people-resistant” system in place to handle all that. At another recent Techtarget event on DR, Jon Toigo talked about a data map and knowing how valuable your data is in order to best protect the most valuable data. Sounds like a straightforward, common-sense approach, but as far as I know only one vendor is doing it in hardware, and most of the software vendors have gone quiet with their marketing behind it.

The term Information Lifecycle Management conjures up thoughts of managed data, orderly storage environments, documented processes, and responsible governance for me. All these things I’ve seen brought up in blogs (some of my own included) and articles, expressed as concerns for businesses large and small. So why has ILM gone underground?
