Description Fibre Channel technology is rapidly replacing SCSI channel attachment between open system servers and disk and tape storage systems. However, many disk and tape storage systems do not provide Fibre Channel attachment. To bridge the gap between Fibre Channel server adapters and SCSI-attached disk and tape storage, IBM has developed the Storage Area Network Data Gateway.The IBM Storage Area Network (SAN) Data Gateway is a hardware solution that enables the attachment of SCSI storage systems to Fibre Channel adapters on specific Intel-based servers running Windows NT and UNIX-based servers from IBM and Sun.
