Hello Ben Thank you for the clarification. I was under the false impression that Linux AIO can be made to use SPDK under the hood which is clearly not the case since they will have to go through the filesystem. BTW are there any known early filesystem implementation besides ceph’s rocksdb based bluestore FS which use SPDK.

Re: [SPDK] SPDK fio benchmark support

by Walker, Benjamin

The fio plugin for SPDK is new and was only tested for a single job. We'd welcome patches to make it span more cores when given more jobs if someone is interested in doing the work here. At some point, I'm sure we'll get to it ourselves, but it's lower priority than the other work we're doing right now (NVMf target). The perf example we provide definitely does scale to many cores though, and it can optionally use libaio as its backend, so it is a great alternative to using fio that works today with no extra effort. As far as expected performance scaling across cores with our perf tool, are you seeing the maximum quoted IOPS for all of the device(s) on the system with only a single core? If you are, adding more cores won't improve performance. If you are not getting the performance you expect from the hardware I'd love to know the details of the devices and the platform. To provide a quick example from my own system (and none of the following should be treated as official benchmarking numbers for any reason), I have a Haswell Xeon E7 with 8 Intel P3700 NVMe SSDs attached. Running the perf tool on my system yields about 3 million 4k read IOPs on 1 core, which is the equivalent of 6 or 7 of my SSDs. Moving to two cores gives me the full hardware spec IOPS for 8 SSDs. If I only test against 4 SSDs I get the same performance (the maximum that the SSDs can provide) no matter how many cores I give the tool.

Hello Are there any SPDK examples which use AIO? Perf.c has very little documentation in the usage for AIO. Regards, Varun Bhadauria

[PATCH] nvme: Return negative errno for failure

The conventional rule for returning errno is negative, hence there is no need to modify caller's code to adjust this NVMe library.
