HP XP7 Provisioning for Open Systems User Guide (H6F56-96009)

The following table describes these items.
DescriptionItem
The capacity (GB) of the area from the dot of the maximum value on the vertical
scale to a specified dot. The capacity of the dot on the vertical scale is 0.00 GB.
Capacities
All I/Os are sorted into 127 sections. The average I/O is the representative I/O
number assigned to each section, based on the definition of the storage system.
By the total number of I/Os, the number of dots may be 127 or less.
Average I/Os
The total number of I/Os in the section from the dot of the maximum value on the
vertical scale to a specified dot. The total I/Os is calculated using the average
Total I/Os
I/Os and capacities in the specified section. If the specified dot is on the vertical
scale, the total I/Os is zero.
When no I/Os are in the lower tier with multiple tiers, the tier range line is placed at 0 on the
vertical scale.
For example, if the dot is placed far from the lower limit of the tier range, the lower limit levels of
the Tier 1 Range and Tier 2 Range are adjusted to improve the visibility of the performance graph.
In this case, the value that is obtained by RAID Manager may not correspond with the value of the
dot displayed in a performance graph.
For V-VOLs
