There is one FBWC (flash backed write cache) module for each Smart Array Controller. Each

FBWC has a capacitor pack to ensure cache contents are maintained after a loss of power. Each

Smart Array RAID controller has an integral capacitor pack, whilst the P410i controller's capacitor

pack is located in the holder in the centre of the HP D2D4312 Backup System. Each FBWC module

has two single-color LEDs (green and amber). The LEDs are duplicated on the reverse side of the

cache module to facilitate status viewing. See the HP Smart Array Controllers for HP ProLiant Servers

User Guide for more information.
