RAID controller
Each RAID controller contains three ports for Small Form-Factor Pluggable
(SFP) modules that connect to the Fibre Channel cables. Two SFPs can
connect to two host systems. The third SFP 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 46.
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. Both fan CRUs must be installed to maintain
proper cooling within the storage server, even if one fan CRU is not
operational.
Hot-swap power supplies
The storage server comes with two hot-swap power supplies. Both power
supplies must be installed to maintain proper cooling.
