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.
