Self-healing coupler for a serial raid device

摘要

A self-healing coupler for a serially linked device that is serially coupled to other devices. The serially linked device has a communication input and a communication output. When a break occurs between a first serially linked device and other devices, as indicated by a lack of communication output from the first serially linked device, the self-healing coupler by-passes the break in the first serially linked device to maintain communication between the other devices. The invention is particularly suited to maintaining communication to serial Redundant Array of Inexpensive Disks (RAID) storage devices.
