ABSTRACT:
A high performance scaleable hardware architecture for a disk array storage subsystem which supports RAID modes 0, 3, 4 and 5. The architecture features a high bandwidth parity calculation engine, a buffered PCI interface operating at the full speed of the PCI bus, and a dedicated local memory. The dedicated local memory is dual ported so that PCI and parity operations may operate concurrently. The architecture of the disk array controller allows parity calculations and memory block moves to occur without interfering with the controller processor or its associated memory, freeing the controller processor to manage array task control. The array controller configuration allows simultaneous operation of data block moves between storage I/O devices and local memory; data block moves between host SCSI connections and local memory; parity calculations; and normal CPU memory fetches, queued operations for block moves and queued operations for parity tasks.
