Hi,

My cluster using Ceph with NVMe drives.

I have some questions:
- How can I know if the NVMe is really working with the maximum performance? Because in "fio" Inside a single vm on a single node I am getting only 30k/s read in average.
- I see all OSD set to class SSD instead of NVMe, is it really affecting on something? If yes, how to change it to NVMe?
- There is more configuration I should to do because of using NVMe?

Thank you
 
Hi,

Have you had a look at this thread and the paper form the thread?

Edit: posted the wrong link, fixed it. It's the same as Neobin's link
