Abstract
A storage controller for redundant arrays of independent disks (RAID) comprises a daughter card containing a standardized controller core, which is mated to one of a number of customizable controller interface cards. The controller core card includes high performance elements such as a processor, cache memory, CRC circuitry, a host port, and a storage port. All operational communication with non-core components occurs via the host port and the storage port through the controller interface card. The controller core card monitors and configures communications between the host and the storage array. Each controller interface card is populated with components and connectors particular to the respective application or RAID system. The size and layout of the controller interface card may also be customized to the particular application. Sharing the same controller core card among various RAID controllers lowers the cost and time-to-market for customized RAID systems.
