how to optimize Proxmox Servers

[Upendra Dhoble]

Hi,
I would like to understand ,how performance of proxmox can be improve in better way

1) anything we can modify swap file system
2) if I do have 10 x 2 TB disk, what will be best option to create volumes ( like LVM or Zfs ) which one is better
3) Failover ethernet card or load balancing if have 50+ vms


Thanks
Upendra

1) always install zram-config for compressed, memory-based swap, also try minimizing swapiness (set to 1)
2) LVM vs. ZFS depends on the layer. ZFS has a lot of features, but steeper learning curve. LVM can mirroring, but normally you have a "real" raid below, not a LVM-backed raid (although possible). Please describe what you plan to do. Do you have a hardware raid card?
3) Load balancing based on LACP or something manual? What about your hardware infrastructure? Do you have failover switches, etc.

I don't have LB or any failover system in placed , just indivisual Proxmox servers however we do have around 10+

If your network hardware is not capable of handling load-balanced traffic, then you cannot use active-active bonding of any kind. You have to check with the manual/spec sheet of your switch. Most managed switches should be able to handle LACP nowadays.

Are you planing on having offline migration between the nodes? Are the nodes connected in a (non-HA, non shared-storage) cluster so that you can manage all via one GUI?

Thanks for reply.
I am not planning for migration , there is no cluster at all.
All my servers are running as a single node however I am trying to make them optimize in performance.

There are a lot of guides and/or recommendations available if you query Google for "sysctl.conf optimization". That might help you.
