Patent ID: 8316244

Claim:
A method for conserving power during a power failure, comprising: receiving a plurality of requests; acknowledging the requests; storing request information associated with the requests in primary memory; detecting a power failure; and in response to the detection of the power failure, resetting a server utilizing a secondary power source, and storing the request information in secondary memory utilizing the secondary power source; wherein, after the reset, the server operates with a first capacity that is less than a second capacity with which the server operates after a reset in an absence of the power failure, for conserving power such that the secondary power source is sufficient for storing the request information in the secondary memory so that the requests can be acknowledged and un-serviced requests are satisfied when a primary power source is restored; wherein the un-serviced requests are satisfied from the secondary memory when the primary power source is restored; wherein it is determined whether power is restored before the request information is stored in the secondary memory.
