File Virtualization may revive HSM?

He does say that it was not best of the things in his last stint.

File virtualization essentially provides the open systems equivalent of the mainframe's hierarchical storage management (HSM), which no one outside of the mainframe world ever hears much about. What HSM does is manage data across different tiers of storage by allowing administrators to set policies that control what data is stored where and how long it is stored there.

Great idea but having seen HSM in use in my last tech position, I hesitate to advocate its use. Why? It takes an inordinate amount of time to set up and manage and with storage so cheap, management simply bought more disk. So the HSM technology is no longer under development at my old company and the individual that was developing HSM is now "retired," at the company's behest.
