Abstract
A method and system for facilitating reliable and fault-tolerant operation of a multi-peripheral-device enclosure for use in high-availability computer systems by redundant interconnection of redundant processors within the multi-peripheral-device enclosure. The redundant interconnection removes a potential single point of failure, and allows the redundant processors to share in control of other components within the multi-peripheral-device enclosure. The multi-peripheral-device enclosure can recover from failure of all but one of the redundant processors, as well as failure in all but one of the redundant busses used to interconnect the two processors.
