Amidst the tangle and bustle of ERP, CRM, NAS, SAN, CAS, and NSF, I have found a new acronym right down the block from where HSM used to live (I grew up with DFHSM; we don't talk about the DF part). ILM 's the name of the new acronym. Pronounced eye-el-em, not "ilm" (perish the thought): information lifecycle management.
I recently sat through a 32-slide PowerPoint presentation (about 14 slides too many) on a vendor's view of ILM. I'll save you the time by giving you the quick version.
