An open serial interface standard developed by IBM called Serial Storage Architecture that has been submitted to the ANSI X3T10 1 subcommittee for approval as an ANSI standard Incorporates a dual port full-duplex module capable of maintaining four conversations simultaneously for a total of up to 80 MBytes/sec Includes multiple signal paths for fault tolerance and provides hot plugging and automatic configuration when nodes are added With shielded twisted pair cable, nodes can be up to 20 meters (65 6 feet) apart The optical fiber implementation extends this to 2 5 Km A loop configuration can support up to 127 nodes Uses 9-pin miniature D-shell connectors with two twisted wire pairs Requires modified system firmware when interfacing to SCSI Mapping for SSA will be included in SCSI-3
Serial Storage Architecture: a peripheral interface from IBM whose ring configuration allows remaining devices to function if one fails SCSI software can be mapped over SSA allowing existing SCSI devices to be used
