Develop a dedicated storage management staff.

Identify and document the storage services provided, the levels for service offered and the prices of each service.

Become the out-source service aggregator and manager (SLA and processes).

Use a combination of backup and recovery techniques, based on application requirements and cost.

Use IT operations staff to execute projects that improve system and storage utilization.

Focus on QOS, not just TCO.
