Abstract
Computer implemented methods and systems for providing storage virtualization of physical storage include receiving a request for storage from a virtual machine during provisioning of the virtual machine. The request includes a capability and quota requirement for storage as required by the virtual machine. A virtual datastore that satisfies the capability and quota requirements of the request is identified. If not found, one or more volumes, that satisfy the storage requirements, are discovered or created. A virtual datastore is created and maps to one or more volumes which have unique volume identifiers. A unique virtual datastore identifier is generated for the virtual datastore. The virtual datastore identifier is distinct from the volume identifiers of the underlying volumes. The volumes are mapped to the virtual datastore while retaining the virtual datastore identifier for the virtual datastore. The virtual datastore identifier for the virtual datastore is not changed when modifications are made to the physical storage entities mapped to the virtual datastore.
