Storage analysis: Mind-meld needed for ILM success

The Information Storage Industry Center , at the University of California, San Diego has released results of a survey on the topic of information lifecycle management. Fathered by storage provider EMC Corp., ILM is a tiered-storage approach, where more relevant items stay readily accessible on speedy storage arrays, and the less-accessed material gets pushed to tapes or cheaper disks. (Long time IT veterans may remember the ILM idea as 'hierarchical storage management,' but we assure you ILM is far more complex, somehow. Well, at least the acronym is fresher).

In any case, " ILM Survey: What Storage, IT and Records Managers Say " summarizes the responses from 346 survey respondents quizzed last February about ILM.

The main findings? Respondents seem to be split over whether ILM is a technology or a policy, with their bias tending towards their own job functions.

In other words, policy managers saw that implementing ILM as a management issue, as it involves crossing organizational lines in order to create a coherent end-to-end record keeping system. The technical folks saw ILM as a collection of storage software tools, some rebranded with the ILM designation.

'[P]rofessionals in the field view ILM in the context of their immediate
work responsibilities,' wrote James Short, ISIC's Director of Research, and author of report.

What is the downside? Until there is a common agreement on what ILM is, successful organization-wide data management through the approach may not be possible.

ILM is, by its very definition, is a cross-enterprise activity, one that involves expertise not only in storage technology, but also domain expertise in knowing which documents are valuable, and for how long. 'The organizational integration needed to produce agreement depends heavily on the strength of partnership between line business management and IT / storage management,' Short concluded.
