The Li-Ion BBU module, a shown above, can sustain cached data for days
during a power failure. The use of a BBU is highly recommended in order
to ensure data integrity. If power outage occurs, the BBU supplies power to
sustain the unfinished writes cached in memory. The BBU module is hot-
swappable.
