A Tier, a Pier?
Posted in Best Practices, Block Storage, Customer Talk, File Storage, Search on July 29th, 2009 5 Comments »

HTSM and VM don’t restrict migrations for local or remote copy functions so that is an error on your part. Early only this was a limitation however it has been removed over time.
The other side of Single Instancing – Re-Instancing?
