This cache card comes with a flash power module
(Supercap pack) that you can attach to this card. It
powers the integrated RAID subsystem long enough to
store the cache contents to flash in the event of a power
loss. The flash power module must be installed remotely
in the server (see “Installing a RAID adapter battery or
flash power module” on page 87 for information about
where to install the flash power module in the server).
v
Provides RAID levels 5 and 50 upgrade support.
