Performance of Volumes by Hypervisor report

Shows the performance metrics for volumes on a hypervisor. Use the report to identify the contribution of individual volumes to the load of a particular hypervisor in your storage environment.

Charts

The charts show the following performance metrics for the volumes:
  • The total overall I/O rates. The chart shows the contribution of each volume to the overall load on the hypervisor.
  • The total data rates. The chart shows the contribution of each volume to the overall load on the hypervisor.
  • The volume utilization percentages. The utilization percentage of each volume is displayed relative to the utilization percentage of the other volumes.
  • The total response times. The response time of each volume is displayed relative to the response time of the other volumes.

Report output

The following information is provided in the report for the period that you specified:
Hypervisor Name
The fully qualified domain name of the hypervisor. For example, the name of a hypervisor might be hypervisor.example.com.
Storage System Name
A user-defined name of the storage system. If a name was not defined, IBM Spectrum Control shows the name that was defined when the storage system was added for monitoring.
Storage Pool Name
The name that was assigned to the pool when it was added to the system.
Storage Volume Name
The name that was assigned to the storage volume when it was added to the system.
Day, hour, or time
The day, hour, or time at which the information about the specified resource or device was collected. Whether the day, hour, or time is displayed depends on the interval that you select for the report.
Total Data Rate (MiB/s)
The average number of MiB per second that are transferred for read operations and write operations.
Total Overall I/O Rate (ops/s)
The average number of read operations and write operations per second. This value includes both sequential and nonsequential operations.
Overall Response Time (ms/op)
The average number of milliseconds to complete an I/O operation. This value includes both read and write operations.
Volume Utilization
The average percentage of time that the volume is busy.
