Abstract: An apparatus, system, and method are disclosed for copying data from a volatile memory device to a plurality of persistent storage devices in response to a loss of primary power. The apparatus includes a section module, a stripe module, and a write module. The section module sections a data image of a write cache into a plurality of data blocks. The stripe module establishes a plurality of data stripes from the plurality of data blocks. The write module writes in parallel each of the plurality of data stripes to a corresponding plurality of unique, persistent data storage devices in response to a loss of line power to the write cache. Advantageously, the apparatus quickly copies the write data from the write cache to a persistent memory device in a relatively short period of time, decreasing the dependence on significant batteries to back up the volatile memory device.

Abstract: A method of providing error notification in a storage subsystem includes writing a first defined value by a host adapter of the storage subsystem to a system management interrupt (SMI) register to generate a hardware interrupt, registering and handling the hardware interrupt by a kernel module of the storage subsystem, writing a second defined value to a shared memory location of the storage subsystem by the kernel module, and reading a shared memory offset value by the host adapter. A system for providing error notification in a storage subsystem includes a controller including a serial management interface (SMI) register subcomponent, a first processing component connected to the controller having a kernel module, and a second processing component connected to the controller executing host adapter software.
