Yeah, I see the same, 6 servers have nvme drives and today in the iops side were all maxed out, but I don’t understand why, the user made head operation like 60000 sometimes in a minute, the cluster iops was like 60-70k and how can this max out 6 nvme drives which should be able to server each more then this iops :(

I’ve seen an estimate of 1% of the size of the buckets pool but this is very much a function of your object size distribution. More but smaller drives would decrease your failure domain and speed up recovery.

At the moment I'm using 6x1.92TB NVME (overkill) but I have no idea how is it used.
