Optional SAS RAID Controller
If you install the optional SAS RAID controller card, you can install two SAS or SATA hard drives and
configure them for RAID 0 or RAID 1 operation.
• See "Expansion Cards" on page 44 for information on installing the optional SAS RAID controller card.
• See the RAID controller card documentation for information about the RAID configuration utility.
Before You Begin
You may need to use different programs than those provided with the operating system to partition and
format SAS or SATA hard drives.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive
failure.
When you format a high-capacity hard drive, allow enough time for the formatting to be completed. Long
format times for these drives are normal.
Installing a Hard Drive
1
If you are replacing an existing hard drive, disconnect the data and power cables from the back of the
drive. See Figure 3-12.
2
To remove the drive carrier from the system, press inwards on the release tabs on each side of the
carrier and lift the carrier from the system. See Figure 3-12.
3
If you are replacing an existing hard drive, deflect the sides of the carrier outward and separate the hard
drive from the carrier.
4
To install the new hard drive in the carrier, fit the left edge of the drive into the carrier, then lower the
right edge of the drive into the carrier until the pins fit into the corresponding holes in the drive.
See
Figure 3-12
.
5
Reinstall the drive carrier into the system.
6
Connect the data cable to the back of the drive.
7
Connect the other end of the cable to the drive controller:
• If you are connecting the drive to the optional SAS controller card, route the SAS data cable
though the oval opening in the chassis brace and connect the cable to the data connector on the
controller card. Secure the data cable to the clips on the edge of the cooling shroud.
• If you are connecting the drive to the SATA controller on the system board, route the SATA data
cable though the oval opening in the chassis brace and connect the cable to SATA connector SATA
A or SATA B. See Figure 6-2.
8
Connect the power cable to the back of the drive. See Figure 3-12.
