The IBM 42R8739 is a PCI-X DDR Dual-Channel Ultra320 SCSI RAID Adapter, IBM machine type 571B, supplied under feature code 5737, with the sibling part 42R8741. The adapter provides two independent Ultra320 SCSI buses with onboard RAID capability for IBM Power Systems and iSeries/AS400 hosts, letting a server address additional internal or external SCSI disk enclosures with hardware-level redundancy rather than relying on software RAID.
Cards of this generation are a common upgrade or replacement part for systems still running SCSI-attached storage rather than SAS or Fibre Channel, and genuine units are a routine requirement when an original adapter has failed or a decommissioned system is being restored to working specification. Tech-Star, UK-based and shipping worldwide, stocks IBM components for server maintenance projects.
