Rate Statistics For Volumes; Cumulative Statistics For Volumes - HP 2000fc Reference Manual

Rate Statistics for Volumes

You can view the following I/O statistics for a selected virtual disk:
The total IOPS and bandwidth for all volumes in the virtual disk
■
The IOPS and bandwidth for each volume in the virtual disk
■
To view volume rate statistics.
1. Select Monitor > Statistics > Volume Rate Stats.
2. Select the virtual disk whose statistics you want to view.
Statistics shown are based on host-side activity in the interval since the page was
last refreshed. The page automatically refreshes at a 60-second interval.

Cumulative Statistics for Volumes

You can view the following I/O statistics for volumes of a selected virtual disk:
The Select A Virtual Disk and Volume Menu panels show all virtual disks in the
■
system and the selected virtual disk's volume name, size, and LUN.
The Details For Virtual Disk Volume panel shows the total number of host read
■
and write operations, sectors read and written, and queue depth for related host
ports for the selected volume.
The Host Read I/O Size Histogram shows how many host read operations fell
■
into a particular size range for the selected volume. The I/O ranges are based on
powers of two.
The Host Write I/O Size Histogram shows how many host write operation fell
■
into a particular size range for the volume. The I/O ranges are based on powers
of two.
The Host Port Details For Volume panel shows the activity for the volume of
■
each port connected to a host. Queue depth is the number of host-originated
commands currently queued for the port. The last I/O size is the size of the last
read or write host access in sectors. An operation that is not a read or write sets
this value to zero.
