Dear Friends,

I am using 2x Samsung 970 Evos as ZFS RAID without Compression On an Asus ESC8000 G4 Server. My VMs are getting stuck (hang) sometimes while playing games. I had no idea why this was happening. When I checked the I/O delay, it's as High as 5-7% sometimes. Could that be the reason? I have no idea how much I/O delay is acceptable.
Server specs-
2 x 4210R CPU
12 x 16GB Ecc Ram
8 x 1660 Super GPU
2 x 2TB 970 Evo SSD
2 x 2TB HDD for backup purpose
500GB SATA SSD (Proxmox Installation)
I have deployed 8 VMs with 16GB RAM, 1 GPU each and 4vCPUs, without Memory balloning (2 Sockets 2 Cores configuration in VM).
