Abstract
In a shared storage infrastructure accessible by more than one customer, the shared storage infrastructure is separated into a plurality of logical storage areas. A customer is associated with at least one logical storage area within the shared storage infrastructure. The customer and its logical storage areas are associated with at least one port in the shared storage infrastructure. Each customer has access only to the logical storage areas associated with the customer and cannot access the logical storage areas of any other customer. The shared storage infrastructure provides policy based storage management to each customer, that is, each customer appears to have access to a non-shared storage subsystem. By providing a virtualization layer, a customer may be given the ability to manage its own storage needs.
