Overview
The Dell™ Serial-Attached SCSI (SAS) 5/iR controller is Dell’s next generation of controller with
integrated redundant array of independent disks (RAID) capabilities. SAS technology is not
backward compatible with the previous generation of SCSI devices. The SAS 5/iR Adapter is a
half-length, standard-height PCI-E card, while the SAS 5/iR Integrated is embedded in the platform
hardware. The SAS 5/iR Adapter is supported on platforms with PCI-E x8 or x16 connectors.
