What is considered a good range for "System Latency" and "System IOPS" - MSA 2060 iSCSI

[asahi]

For a MSA 2060 iSCSI, what is considered a good range for "System Latency" and "System IOPS"?

When  should someone start worrying about performance? Would you pleasae provide examples?

Thank you

Hi,

Below-mentioned values are not MSA 2060 specific.

Generally controller average host port write latency of less than 10ms and read latency of less than 15-20ms would indicate optimal performance.

I was hoping to have for the performance stats of a MSA 2060 so that I can compare them to the stats provide in the "Storage Management Utilty."

Is there a web site or document that would have them?

Read/Write for System IOPS (I/O per second)

System Latency (Avarage Response Time in microseconds)

System Throughput (MB per second

Controller IOPS (I/O per second)

Volume Average Queue Depth (Avarage Queue Depth)

Hi,

Apart from the performance benchmark results in MSA quick specs sheet (pages 29-31), we dont have any documents that lists the information requested:  https://www.hpe.com/psnow/doc/a00094630enw.pdf?jumpid=in_pdp-psnow-qs
