Hi All,

No issues, but I would like some advice on how to optimise usage for a single Windows 11 VM and file sharing (Samba).
Proxmox has been a revelation for me, I've used virtualisation with other distros but Proxmox just works.

The Windows 11 VM hosts a legacy database that must reside on a machine with a MS OS. Nobody uses this VM directly - it just shares files.
Samba is then used for general (office) file sharing - 10 users maximum.

Currently the Windows 11 VM is setup as follows:-

I've bonded the 4 port NIC. The VM resides on the 1TB SSD.

Given the (possibly) under utilised hardware below, can I change things to improve the VM and Samba performance?

For example:-
  • Run the VM and Samba storage completely in RAM
  • 'Un-bonding' the NICs and allocating separate ports for the VM and Samba
  • Tweaking the VM's/Samba settings
  • Move all shared files to the VM and not use Samba
  • Change the method for storing VMs - Change RAID mode/remove RAID
Hardware consists of following:-

Dell 940 Server
256GB Memory
4 x XEON Platinum CPUs (56 Core each)
2 x 256GB (RAID 1 for OS only)
2 x 2.4TB SAS, 2 x 1TB SSD (RAID 1 with battery backup)
4 Port 10GB/1GB NIC - 1GB backbone.

2 x UPS individually connected to server's 2 x redundant PSUs.


Grateful for any suggestions/advice/pointers - Diolch/Thanks
