    摘要: A multiprocessor computer system and associated method having processing error detection capability is disclosed for error-free processing of an instruction set. The instruction set is replicated and processed substantially in parallel through a plurality of processing nodes of the computer system. Each processing node collects a compressed hardware signature commensurate with and derived from the execution of the instruction set. Subsequent instruction set processing, the collected hardware signatures from each processing node are compared and the presence or absence of a processing error is determined with reference to a predetermined voting scheme. Processing of the instruction sets through the plurality of processing nodes is typically asynchronous with synchronization occurring subsequent each processor's execution of the instruction set, such that each processor can be driven by an independent clock.

    摘要: One method of redirecting an in-process backup operation to a new storage device involves receiving a request to perform a backup from a backup application. In response to reception of the request, the method causes backup information generated by the backup application to be stored on a first storage device. The first storage device is monitored in order to detect how much free space is available. If the amount of space available on the first storage device drops below a threshold amount prior to completion of the backup, the backup is redirected by causing any subsequent backup information generated by the backup application to be stored on a second storage device. Metadata associated with the backup identifies that information associated with the backup is stored on both the first storage device and the second storage device.
