Cisco UCS B440 M2 Blade Server

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.
