Abstract: A high-performance spare disk pool is created as a logical construct for provisioning and managing striped hot spares. Two or more drives (nonvolatile mass storage devices) are logically grouped together to allow the input/output (I/O) write bandwidth during RAID reconstruction to be increased over that of a single drive. The reconstructed data can be written to the spare disk pool in a striped manner. After the reconstruction is complete, a background process can be executed to copy the reconstructed data on the spare disk pool back to a single physical spare disk drive with minimal performance impact.
