Virtual server environments require real and physical data protection. After all,you cannot go forward from a disaster or loss of data if you cannot go back to aparticular point in time and recover, restore, and restart, regardless of yourbusiness or organization size.

Understanding the relationship between different resources and how they are
used is important to gauge improvement and productivity as well as datacenter efficiency. For example, while the cost per raw terabyte may seemrelatively inexpensive, the cost for I/O response time performance needs to beconsidered for active data.
