The FAStT100 has blank trays in the unused drive bays. To begin installing new
drives, you must first remove the blank trays and save them. Each of the 14 bays
must always contain either a blank tray or a drive CRU. You can install up to 14
hot-swap drive CRUs in the storage server.

RAID controller
Each RAID controller contains three ports for Small Form-Factor Pluggable
(SFP) modules that connect to the fibre channel cables. Two of the SFP
ports (labelled Host 1 and Host 2 ) are for host server attachment. The third
SFP port (labeled Expansion ) is used to connect additional expansion units
to the storage server.
Each RAID controller also contains a battery to maintain cache data in the
event of a power failure. For more information, see “Cache memory and
RAID controller battery” on page 66.
Hot-swap fans
The storage server has two interchangeable hot-swap and redundant fan
CRUs. Each fan CRU contains two fans. If one fan CRU fails, the second
fan CRU continues to operate. You must install both fan CRUs to maintain
proper cooling within the storage server, even if one fan CRU is not
operational.
