  • Host-memory based raid system, device, and method
    Patent number: 6526477
    Abstract: A host-memory based RAID system, device, and method are provided. The host computer has a host memory for storing data and parity data and is coupled to a RAID system, which includes a RAID array and a RAID controller. The RAID array includes a plurality of disk drives for storing first data and first parity data. The RAID controller is coupled to the RAID array for interfacing the disk drives of the RAID array with the host computer. The RAID controller receives new data from the host memory for storage in the RAID array and is configured to generate new parity data by performing one or more XOR operations. The host memory is configured to include an XOR buffer for storing the result of the one or more XOR operations. Other configurations include a RAID-enabled SCSI device that includes a SCSI controller and a RAID accelerator.
