A device and method for a peripheral adapter of a dual SCSI bus enclosure is described. An adapter can operate alone or in pairs to provide different modes of operation, including simplex, duplex, and cluster. When used in pairs, two adapters interconnect internally to the enclosure through internal cross-coupling bus repeaters that can be selectively enabled or disabled. The adapters are hot-swappable and have the ability to automatically self configure. In the cluster mode, the adapter supports failover capability from a master adapter to a redundant adapter.
