  • Understanding the current state of your storage infrastructure—what capacity you have, where it is located, who is using it, who is paying for it, how efficiently it is being used, and how well it is meeting SLAs—is fundamental to intelligently planning, provisioning, and managing storage.

  • In a 2004 survey of 200 IT professionals from 14 countries in the Americas, Asia/Pacific and Europe, the IT Governance Institute (ITGI) found that in 80% of organizations, IT management is solely responsible for defining and addressing IT risk impact.
