CONFIGURING the SERVER
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 7. 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 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.
