Cisco UCS B440 M2 Blade Server
CONFIGURING the SERVER
15
STEP 5 CHOOSE RAID CONFIGURATION
The B440 M2 server integrates the LSI SAS2108 6G SAS RAID controller.
Choose RAID Options
If desired, choose the RAID 5, 6 upgrade option and battery backup option listed in Table 8. The
BBU is an intelligent battery backup unit that protects disk write cache data during a power loss
on the RAID controller for up to 72 hours. We recommend that you replace the battery backup
unit (BBU) once per year or after 1,000 recharge cycles, whichever comes first.
Caveats
■ No RAID option will be effective if you have a mix of SAS and SATA drives.
■ No RAID option is possible if you have no drives.
■ You must have at least one drive installed in order to add an optional battery backup unit.
CAUTION: Hot swapping the BBU is not supported. Please perform a graceful
shutdown of the server prior to replacing the BBU.
