Data Storage Management Issues

"In the past, when enterprise disk was expensive and hiding too many MP3s on the company server really did waste money, information life cycle management (ILM) was the mantra: an ILM system would make sure the different tiers of storage were used appropriately.

Unfortunately, in practice what happened was the first place that data was assigned turned out to be the place it sat, whether it was an appropriate tier or not. Is it appropriate for every organisation today? No, sometimes it really is easier to buy more disk. But eventually we will have environments where the data resides on an appropriately performing disk without any intervention from the administrators at all.
