4.8 Connecting the Battery Pack
The XStack Storage unit comes equipped with a standard 6-cell battery pack to provide back up of
the buffer cache contents (See
Figure 4-1). Since write-back caching is always enabled on the
XStack Storage unit, we recommend you have a battery installed at all times.
