Hi,
I have a question about best solution for best performance regarding volume sizes.
We have one Supermicro server, SSG-6048R-E1CR36N, with 2 x CPU E5-2620v3, 256GB RAM and 11 x 4 TB SAS, 11 x 8 TB SATA, 6 x 500 GB SSD and 4 x 256GB SSD. (We have one more with the same performance for our backup system.)
This storage will serve our virtual cluster running Proxmox on four physical nodes. We have 40 running virtual machines.
The disks are for now
I feel sometimes that it is slow to read / write from the virtual machines.
Here comes my question:
Will I get better perfomance if I makes smaller volumes, two smaller 5 and 6 x 4 TB SAS RAIDZ2 instead of one 11 x 4 TB SAS RAIDZ3?

The disks are for now
- 11 x 4 TB RAIDZ3 for most of virtual disks.
2 x 256 GB SSD mirrored for logs
2 x 256 GB SSD mirrored for cache
- 6 x 500GB SSD RAID10 for databases
- 11 x 8 TB RAIDZ3 for backup copies
