ESX to PVE migration - specify interface for import traffic

Hi All,

I have been using Proxmox for a couple of years since B-Day, and I'm working through a POC right now internally and have everything setup with the available hardware to me, but I've found a potential limitation and cannot find anyone else talking about this, either I can't get the right combination of terms, or it's not explicitly defined in the documentation.

I have multiple HPE hosts with 4 nics, nic0/1 bonx for mgmt/vmotion, nic 2/3 for iscsia/b traffic paths. I am noticing a delay in importing VMs and it's saturating my management interface on the source and dest nics. They are 25Gbps, but I'd like to separate out the import traffic from the management interface. Is this possible?

While monitoring the import with nload -m I can see the incoming hitting 600-700MBps, which is 1/5th of the network traffic on that interface. Currently an import for a basic VM with 127GB drive is taking 30ish minutes. I'm exploring other storage platforms and import methods, but given the ease of use, this may be our primary way so my team can accomplish the task.

I have set up an explicit vlan for migration traffic, and I've verified this on my home lab between hosts, but not in an import scenario. I believe this is specific PVE traffic and not import traffic.
i.e.
nic 0 mgmt
nic 1 migration
 
Hi DJKrafty,

Welcome to the forums!

I saw there were no replies yet to your post, and intended an attempt to change that situation. I did not get to write anything useful, I'm afraid.

After reading your post four times, I've trouble separating the the noise from your actual question. B-day? Bonx?

If an issue bothers you enough to create an account for it, you might invest some attention to layout that issue in such a way that visitors of the forum, in their free time, are helped understanding what you are trying to convey.

@DJKrafty: have I figured those correctly? :)

You are correct on both counts. After the Broadcom announcement I completely wiped my lab to adopt Proxmox and I did mean Bond.


I was asking if there are any methods to separate import traffic from ESX onto a specific interface.

Today it uses my my first nic and my mgmt vlan to pass the traffic. I have other interfaces that I can enable jumbo frames on which should, theoretically, make importing faster.
