Hi All,

 

I tested the scale out ceph from proxmox but not yield good results. I use crucial ssd disks.

I like to test the petasan with compatible nvme drives.

 

May I know the list of compatible nvme drives.

 

Thank you,

Manivel RR

PetaSAN supports nvme drives, always use enterprise class for performance. Ceph does a lot of sync writes which performs poorly on non enterprise class drives.

All are compatible. Use enterprise class devices. Samsung and Intel are very good.

Note: due to the distributed nature of the Ceph storage, nvme and ssd will give similar performance, the first is a slightly faster if the total drive count is very low, else they give same performance.
