A method for providing virtual private storage array (VPSA) service for cloud users over a computer network includes receiving parameters for the VPSA over the network and creating the VPSA from resources of server computers. Creating the VPSA includes allocating and exposing drives that meets or exceeds specified drive characteristics, drive quantity, and array redundancy criteria to virtual controllers (VCs) in the VPSA, and dedicating parts of processor/memory complexes that each meets or exceeds a specified virtual controller hardware model to the VCs. The VCs run on virtual machines on the dedicated parts of processor/memory complexes on independent server computers. The VCs discover the exposed drives, create a virtual pool from the exposed virtual drives, implement data protection on the virtual pool, create volumes from the virtual pool, expose the volumes over the network to a customer computer, and handle access requests to the volumes from the customer computer.

Methods and systems for improving performance in a storage system utilizing snapshots are disclosed by using metadata management of snapshot data. Specifically, various metadata structures associated with snapshots are utilized to reduce the number of IO operations required to locate data within any specific snapshot. The number of IO operations are reduced by allowing the various metadata structures associated with the temporally current snapshot to locate data directly within any temporally earlier snapshot or on the original root volume.
