5-13 Enabling SAS RAID

After the hardware is set up, you should install the operating system and the SAS
RAID drivers, you may wish to confi gure a RAID array with your SAS drives. This
section gives an outline of the Adaptec SAS Utility program and instructions for
creating a RAID array on your system.
Serial Attached SCSI (SAS)
Serial Attached SCSI (SAS) is a physical storage technology that employs a serial
transmission of data with SCSI protocol. Serial transmission results in the use of
much thinner cables than those used for (parallel) SCSI data transmission. This
serial link supports a transfer rate from 3 Gb/sec.
Enabling SAS RAID
Before entering the SAS utility, you must enable SAS with the onboard jumper (see
Chapter 1). After setting the SAS jumper to "enabled", power up the system and
hit the <Cntrl> + <A> keys on boot up to enter the utility. You should then see the
main screen as shown in Figure 5-6.
