Overview
The Dell™ Serial-Attached SCSI (SAS) 6/iR controller is Dell’s next generation controller with
integrated redundant array of independent disks (RAID) capabilities. SAS technology is not
backward compatible with the previous generation of SAS or SCSI devices. The SAS 6/iR Adapter is
a half-length, standard-height PCI-E card, while the SAS 6/iR Integrated is embedded in the
platform hardware. The SAS 6/iR Adapter is supported on platforms with PCI-E x8 or x16 connectors.
