Hard Drives
Your system supports 3.5-inch (SAS or SATA) hard drives in 3.5-inch 
hot-swap hard drive carrier. The hard drives are installed at the front of the 
system (see Figure 3-1). Front-mounted hard drives are connected to a SAS 
backplane through hard-drive carriers and can be configured as hot-
swappable.
Removing a Hard-Drive Blank 
  CAUTION: To maintain proper system cooling, all empty hard-drive bays must 
have drive blanks installed.
