Abstract
The present invention provides for a method for managing the storage of data in a computing system that includes a data processor and local physical storage, involving the steps of: defining a virtual storage volume for access by the data processor, the data processor including a local storage pool mapped to the local physical storage and a remote storage pool mapped to physical storage at a remote site, and the virtual storage volume being overallocated with respect to the local storage pool; and migrating data between the local storage pool and the remote storage pool according to a defined migration policy.
