Abstract
An information handling system may include a processor, a tape drive coupled to the processor, and a cache control module. The cache control module may be configured to receive a request from the processor for the tape drive; determine whether the tape drive is powered off; determine whether the tape drive needs to be powered on to process the request; and respond to the request on behalf of the tape drive if it is determined that (a) the tape drive is powered off and (b) the tape drive does not need to be powered on to process the request.
