Installing a Hard Drive Into a Hard-Drive Carrier
1
Insert the hard drive into the hard-drive carrier with the connector end of 
the drive at the back. See Figure 3-9.
2
Align the holes on the hard drive with the holes on the hard-drive carrier.
When aligned correctly, the back of the hard drive will be flush with the 
back of the hard-drive carrier.

Attach the four screws to secure the hard drive to the hard-drive carrier.
Internal Hard Drives
All twelve–hard-drive systems support two cabled 2.5-inch (SAS or SATA) 
internal hard drives. Internal hard drives are connected to the SAS backplane. 
It is recommended that you install the operating system on the internal hard 
drives in a RAID 1 configuration. For information on RAID configuration, see 
the RAID documentation at support.dell.com/manuals.
