Abstract
A storage adapter for use in a data storage subsystem includes a controlling processor, a volatile memory, and a nonvolatile memory 'dump device.' The storage adapter also includes a battery that can be used to provide sufficient power to the storage adapter to allow data from the volatile memory to be written to the nonvolatile memory of the storage adapter under the control of the processor in the event of an interruption or failure in the main power supply to the storage adapter, i.e. to preserve data stored in the volatile memory in that event. The processor uses the current state of charge of the battery to determine the amount of data that can be 'dumped' to the nonvolatile dump device before the battery is depleted.
