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.
Claims20
An information handling system, comprising:
- a processor;
- a tape drive coupled to the processor;
- and
- a cache control module configured to:
- receive a request from the processor for the tape drive;
- determine whether the tape drive is powered off;
- determine, based at least on the request, 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.
An apparatus, comprising:
- a cache control module configured to:
- receive a request from a processor and intended for a tape drive;
- determine whether the tape drive is powered off;
- determine, based at least on the request, 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.
A method, comprising:
- receiving at a cache control module a request from a processor intended for a tape drive;
- determining whether the tape drive is powered off;
- determining, based at least on the request, whether the tape drive needs to be powered on to process the request;
- and
- responding 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.
