摘要: A disk array system comprises a plurality of automated controllers, each which implements host side standard ATA interface protocol within circuitry to control respective drive. Each controller preferably includes command buffer for storing drive commands be executed by drive, and data that stores I/O being transferred or from the In preferred embodiment, controllers are connected bus microcontroller dispatches in response requests computer, also second an processor. The processor transfers between controllers/ATA drives tracks completion statuses pending requests.
