Disk drive initiated data transfers responsive to sequential or near sequential read or write requests |
摘要 |
If consecutive read or write requests imposed on a DASD are of the same type and bear a defined sequential logical address relationship (pure sequential, near sequential), then a circular buffered data path using a pair of a synchronously managed read/write ports respectively coupling either a cyclic, concentric, multitracked storage medium or a cyclic, spiral-tracked storage medium and a device interface can continue data streaming unabated. Otherwise, the path would ordinarily have to be disabled and reconnected using a control microprocessor in respect of any random sequence of requests.
