The SAS 9311 8 and 4-port, 12Gb/s SAS host bus adapter family provide increased connectivity and maximum performance for high-end servers and appliances within internal storage, or connecting to large scale storage enclosures.

The SAS 9311 HBA family is based on the SAS 3008 IO controller, integrating the latest enhancements in SAS and PCI Express® technology. Each host bus adapter also supports 8 or 4 SAS ports operating at 12Gb/s data transfer rates, and can reach over 1 million IOPs. The 9311 adapter family supports 8 PCI Express lanes that comply with the latest PCI Express 3.0 specifications. In addition, these adapters are backwards compatible with previous SAS and PCIe generations through automatic negotiation, and provide SAS data transfer rates of 12, 6, and 3 Gb/s per lane, and SATA data transfer rates of 6 and 3Gb/s per lane.

The SAS 9311 adapter family offers Integrated RAID (0, 1, 1E, and 10) support. Due to simplifying the configuration options and offering a IR firmware support for its 6Gb/s SAS host adapters, these integrated RAID solutions provide a low cost option for the server or workstation market which requires the extra performance, storage capacity, and/or redundancy of a RAID configuration.

Integrated RAID offers distinct performance and reliability advantages, including reduced CPU levels on your host computer, and also volumes that are OS agnostic.

The Integrated RAID solution includes the following RAID features:

  • The Integrated Mirroring solution, which provides features of RAID 1
  • The Integrated Mirroring + Striping solution, which provides features of RAID 10
  • The Integrated Mirroring Enhanced solution, which provides features of RAID 1
  • The Integrated Striping solution, which provides features of RAID 0
