NVMe performance benchmarking

Hi,

In the specifications of NVMe storage devices HPE specified Q for queues. Eg: MAX Random Read IOPS (4KiB):  575,000@Q16.

What is this Q,

is it the number of queues used in NVMe protocol or is it the number of queues set on the benchmarking tool.

How can we compare this output with a preformance test from fio.

Re: NVMe performance benchmarking


Hi,

Queue depth is the number of I/O requests that can be queued at one time on a storage controller.
