Volume performance

You can change how often the system refreshes performance information on the page by clicking the Refresh every list, and choosing a different value. The default refresh interval is 10 seconds if the cluster has less than 1000 volumes; otherwise, the default is 60 seconds. If you choose a value of Never, automatic page refreshing is disabled.

Write IOPS

The total number of write IOPS currently being executed against the volume.

Total Throughput

The total amount of throughput (read and write) currently being executed against the volume.

Read Throughput

The total amount of read throughput currently being executed against the volume.

Write Throughput

The total amount of write throughput currently being executed against the volume.

Total Latency (ms)

The average time, in microseconds, to complete read and write operations to a volume.

Read Latency (ms)

The average time, in microseconds, to complete read operations to the volume in the last 500 milliseconds.

Write Latency (ms)

The average time, in microseconds, to complete write operations to a volume in the last 500 milliseconds.

Queue Depth
