SAS RAID 0/1 controller (based on LSI 1064e)
The controller LSI SAS RAID 0/1 based on LSI MegaRAID® doubles the performance of todays dual channel Ultra320 SCSI HBAs by connecting an 4-lane 2.5Gb/s PCI Express bus with up to eight 3Gb/s SAS/SATA ports. It offers leading SAS and SATA RAID and non-RAID data off-load for medium to high-capacity internal server storage applications.
