Installing SAS Hard Drives

This subsection describes how to install and configure SAS hard drives in the system's internal hard-drive
bays. Your system features up to five 3.5-inch hard drives, or eight 2.5-inch hard drives. All drives connect to
the system board through one of two optional SAS backplane boards. See "SAS Backplane Boards"
on page 13 for information on these backplane options.
Hard drives are supplied in special hot-pluggable drive carriers that fit in the hard-drive bays.
NOTICE:
Before attempting to remove or install a drive while the system is running, see the documentation for the
SAS RAID controller card to ensure that the host adapter is configured correctly to support hot-plug drive removal
and insertion.
NOTE:
It is recommended that you use only drives that have been tested and approved for use with the SAS
backplane boards.
You may need to use different programs than those provided with the operating system to partition
and format SAS 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. A 9-GB hard drive, for example, can take up to 2.5 hours
to format.

Removing a Drive Blank

NOTICE:
To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed. If you
remove a hard-drive carrier from the system and do not reinstall it, you must replace the carrier with a drive blank.
The process for removing a drive blank depends on whether your system is configured with 3.5-inch
or 2.5-inch hard drives.
For 3.5-inch hard drive configurations:
1 Remove the front bezel, if attached. See "Opening the System" in the Installation and Troubleshooting
Guide.
2 Insert your finger under the shrouded end of the blank and press in on the latch to eject the blank
outward from the bay.
3 Pry the ends of the blank outward until the blank is free.
