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 SCSI devices. All SAS 6/iR controllers are half-length, standard-
height PCI-E cards, except for the SAS 6/iR Integrated controller on the blade
servers and on the Precision workstations. The SAS 6/iR controllers are
supported on platforms with PCI-E x4, x8 and x16 connectors.
