Abstract
A system and method described herein allows a virtual tape library (VTL) to perform multiple simultaneous or parallel read/write or access sessions with disk drives or other storage media, particularly when subject to a sequential SCSI-compliant layer or traditional limitations of VTLs. In one embodiment, a virtualizing or transaction layer can establish multiple sessions with one or more clients to concurrently satisfy the read/write requests of those clients for physical storage resources. A table or other data structure tracks or maps the sessions associated with each client and the location of data on the physical storage devices.
