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.
