Abstract: An adapter for converting an interface of a data storage device is provided. The adapter has a first interface for connection to the interface of the data storage device and a second interface for connection to one or more host systems. The adapter includes a processor for converting commands and data between the first and second interfaces. The adapter transforms the data storage device to emulate physically and logically a higher availability and higher performance native data storage device. The adapter has a first connector compatible with the first interface for attachment to the data storage device and a second connector compatible with the second interface for attachment to the one or more host systems. The first and second connectors are disposed in the adapter in a back to back arrangement. The adapter logically separates commands for the data storage device from commands for the adapter.

Abstract: A spindle synchronisation technique is described which is useful in a disk array subsystem comprising a plurality of disk drives (40,41,42,43) connected by means of serial links (25,26,27,28) to a disk drive controller (20). Data and command information is transmitted over the link in the form of multi-character frames, the flow of which is regulated by special ten bit protocol characters. A SYNC protocol character is defined which is used to synchronise the spindles of the disk drives. This SYNC character is issued by controller to selected ones of the drives over the same link used for the transmission of the command and data information. The SYNC character may be interleaved between the characters of frames being transmitted over the link.
