I seemed to have touched a nerve with Barry Burke in my last post on tiered storage myths, where I talked about the advantages of tiering across internal and external tiers of storage.

The Differences Between Tiering and HSM – Hierarchical Storage Management
Posted in Hardware, Storage Software, Virtualization on May 12, 2011 1 Comment »
