Proxmox and jumboframes

[mo_]

Hi,

Ive read old posts from 2012 and older indicating that there were limitations to the mtu since pve-bridge seemed to limit those. Has this changed, can we use mtu 9000 for the cluster communication network now (proxmox 3.4)? This would be handy since the traffic of talking to Ceph is using that network as well (which itself obviously needs jumboframes for good performance)


Thanks

I think you should have no problem!, your switch must have jumbo frames enabled

We use Jumbo frames with proxmox openvswitch based bridges:

Works great.
