ABSTRACT:
A system for implementing RAID-5 parity generation and reconstruction. Data for an array of disk drives is placed in an I/O buffer. The RAID-5 parity engine creates parity data and stores the resulting parity data in the I/O buffer as well. The I/O buffer (both the data and the parity) is then sector-striped across a network of disk drives, such as a Fibre Channel network. The RAID-5 parity engine creates parity on multiple stripes of data upon a single activation of the engine. The RAID-5 parity engine can reconstruct a sector of data using the parity information. The RAID-5 parity engine can also check the data against its expected parity.
