EMC Symmetrix Disk Performance
Table: EMC Symmetrix Disk Performance
Metric | Description |
|---|---|
Percent Busy | The % of time that the disk group is busy serving I/O requests. |
Avg Queue Depth | Calculated value: Accumulated queue depth/total SCSI commands per second. |
Total SCSI Commands | Total number of commands performed by the disk each second: read, write, skip mask, verify, XOR write, and XOR write-read. |
Disk Reads | The number of reads per second for the disk. |
Disk Writes | The number of writes per second for the disk. |
MB Read | The read throughput of the disk, in MB per second. |
MB Written | The write throughput of the disk, in MB per second. |
Read Response Time | The average time taken by the disk to serve one read command. |
Write Response Time | The average time taken by the disk to serve one write command. |
IOs | The total number of read and write I/Os per second for the disk. |
