Hard Drives
Depending on your chassis and backplane, your system has one of the following
configurations:
• Sixteen 2.5-inch drive bays
• Eight 3.5-inch drive bays
All chassis support hot-swappable SAS and SATA hard drives, and the 2.5-
inch–bay chassis also supports hot-swappable SSD hard drives in systems with
integrated PERC controllers.
All drives are installed at the front of the system and connect to the system
board through the SAS backplane. Hard drives are supplied in special hot-
swappable hard-drive carriers that fit in the hard-drive bays.
CAUTION:
Before attempting to remove or install a drive while the system is
running, see the documentation for the storage controller card to ensure that the
host adapter is configured correctly to support hot-swap drive removal and
insertion.
CAUTION:
Do not turn off or reboot your system while the drive is being formatted.
Doing so can cause a drive failure.
NOTE:
Use only drives that have been tested and approved for use with the SAS
backplane board.
When you format a hard drive, allow enough time for the formatting to be
completed. Be aware that high-capacity hard drives can take a number of
hours to format.
Mixed SAS/SATA Hard-Drive Configurations
Mixed hard-drive configurations of SAS and SATA drives are allowed. In this
configuration, two SAS drives must be installed in hard-drive slots 0 and 1
only. Up to six SATA drives may be installed in the remaining slots.
Mixed 2.5-inch and 3.5-inch configurations of SAS and SATA drives are also
supported
in the 3.5-inch–bay chassis only . In this configuration, two 10,000-
RPM 2.5-inch SAS drives installed in 3.5-inch adapters must be used in hard-
drive slots 0 and 1 only.
The remaining hard drives must be 3.5 inches in size
and must be either all SAS or all SATA drives.
