Description

Metric

Metric category

Single CLPR, data ac-
cessed or the reads on a
single CLPR.

CLPR Read Hits

Cache IO Metric

Applicable only for XP disk
arrays.
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 thin provisioning
environment where an
ACP pair is associ-
ated 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 utiliza-
tion also correlates to
the utilization of RAID
groups associated
with a ThP pool.
