appears. The vertical scale indicates the average number of I/Os on an hourly
basis. The number of I/Os is a weighted, averaged with the monitoring data
from the past cycle weighted against the monitoring data from the current cycle.
The horizontal scale indicates the capacity.
If there is no monitor data, this item does not appear.
If Tiering Policy and the period mode of the monitoring mode are specified, this
item appears. When the check box is selected, the performance graph appears. Policy
The vertical scale of the performance graph indicates the average number of
I/Os on an hourly basis. The horizontal scale of the performance graph indicates
the capacity.
If there is no monitor data, this item does not appear.
If Tiering Policy and the continuous mode of the monitoring mode are specified,
this item appears. When the check box is selected, the performance graph Policy(Weighted average)
appears. The vertical scale of the performance graph indicates the average
number of I/Os on an hourly basis. The horizontal scale of the performance
graph indicates the capacity.

The following describes how to read the performance graph when it contains pool information.
The vertical scale of the graph indicates an average number of I/Os by each hour and the horizontal
scale indicates capacity (GB) of the area where the I/Os are performed.
The two lines in the graph indicate tier 1 range and tier 2 range. They are calculated when the
collection of performance monitoring has been completed (monitoring period is completed). They
show the boundary of each tier.
A maximum of 127 dots is shown in the graph. The following information appears over a dot in
the graph depending on where the cursor is placed.
•
Capacities, average I/Os, and total I/Os appear if the cursor is placed on the dot of the
Tier1, Tier2, Tier3, Pool, or the Pool(Weighted average).
•
The lower value of the average I/Os appears if the cursor is placed on the dot of the Tier1
Range or the Tier2 Range.
