I've tested fio in the boot disc (1x SSD) and I was not even getting 300MB/s and on windows I get 500MBs I think I have my conclusions but what to do next don't know!

Thanks for the reply, I've added a total of 12 SATA drives to my VM in two separate AHCI SATA args onf the VM.conf. This way I could use 12 disks passthrough to my VM from my netapp shelf.

Hello all, After adding the "args" to the VM conf. file the drives apear in the VM when booted but not at hardware section on the proxmox VM. Any thing missing besside the "args" line ? Thanks
