This is a bit unnerving. Symantec’s new “State of the Data Center” report reveals that half of all data centers are understaffed.

As you would suspect, many of these technologies read like a Green IT 101 checklist: cloud computing, automation, server virtualization and consolidation, and data center consolidation.
