Example – ACP Pair BH
has B as the left ACP card
and H as the right ACP
card.
• The total utilization of
the ACP pair.
• In a ThP environment
where an ACP pair is
associated with a ThP
pool, the ACP Pair Util
Total metric provides
the ACP utilization
due to the I/O cache
miss (where frontend
I/Os occurring on a
ThP pool are received
at the array backend).
In this case, ACP utiliz-
ation also correlates
to the utilization of
RAID groups associ-
ated with a ThP pool.
