Chapter 1 Overview
Storage
Drives are installed into front-panel drive bays that provide hot-pluggable access.
The server is orderable in three different versions, each with one of three different
front panel/backplane configurations
:
•
Cisco UCS C240 (small form-factor (SFF) drives, with 24-drive backplane
and expander). Holds up to twenty-four 2.5-inch hard drives or solid state
drives.
•
Cisco UCS C240 (small form-factor (SFF) drives, with 16-drive backplane, no
expander). Holds up to sixteen 2.5-inch hard drives or solid state drives.
•
Cisco UCS C240 (large form-factor (LFF) drives, with 12-drive backplane and
expander). Holds up to twelve 3.5-inch hard drives.
The server also contains one internal USB port on the motherboard that you can
use with a USB thumb drive for additional storage.
Cisco Flexible
Flash drives
The server can be ordered with up to two optional Cisco Flexible Flash drives (SD
cards).
This drive is pre-loaded with four virtual drives. The four virtual drives contain,
respectively, the Cisco Server Configuration Utility, the Cisco Host Upgrade
Utility, the Cisco C-Series server drivers set, and a blank VD on which you can
install an OS or a hypervisor. See
Replacing a Cisco Flexible Flash Card, page 3-61
for more information.
The two flash drives can be configured in a RAID 1 configuration to protect your
hypervisor VD.
