Single port.
The maximum frontend
I/Os rate on this port over
an entire collection inter-
val. It is the maximum of
the last collection interval.
For example, if port I/O
collection interval is set to
two minutes, the Maxim-
um Port IO will be calcu-
lated as the maximum
value over the two minute
collection period.
Maximum Port IO – Fron-

The minimum frontend
I/Os rate on this port over
an entire collection inter-
val.
Average Port IO – Fron-

The average frontend
I/Os rate on this port over
an entire collection inter-
val.

The total IO/s (reads and
writes) on that port over
a given duration. This
port in turn connects to
the host group through
which the I/Os reach the
port.
Total IO/s – Frontend
Single host group.
The total IO/s (reads and
writes) on the selected
host group over a given
duration.
Total IO/s – Frontend
Each RAID group value is
the sum of the LDEVs in the
RAID group.
The sum total of the fron-
tend I/Os on all the
LDEVs created in a RAID
group.
