Words matter… so do acronyms. We’ve seen a new category of storage management software developed which is being referred to as, you guessed it, “Storage Management Software.” Some have questioned whether this is something new or if it is just another offering of HSM (Hierarchical Storage Management). There are differences between the two categories. This isn’t just about product positioning or marketing; it’s about what certain products do or don’t do and whether or not they are a fit for your data center or a specific need. Both solution types are designed to keep frequently accessed data on the fastest storage (usually the most expensive and least dense) while moving inactive data to slower storage (usually much less expensive and significantly more dense). How the solutions accomplish this is very different.
