Hello Proxmox Community,
Not sure if this question ever came up here, but i could not find anything. Is it possible to use 2 NICs with 2 different subnet in a Proxmox box?
My plan is to connect one of the NIC to switch where all the NAS/SAN is connected. Then connect the other NIC to a switch where all the client PC are connected. This way i can keep the main client network traffic free, since large volume of data do not have to travel through main client network from the NAS/SAN.
If it possible, what would be the configuration setup for that?
Thanks!

Sure no problem, this is a standard setup. (This is always good to separate lan/san network)

Awesome!
So how about this following configuration that i am thinking?
NIC 1, Client Facing
------------------
IP : 192.101.50.2/24
Gateway : 192.101.50.254

NIC 2, SAN Facing
-----------------
IP : 192.101.60.2/24
Gateway : blank

This should work without further configuration?

Essentially, I think you would need to just look up networking for Debian. I've done this before but I cannot remember exactly how. I think in a nutshell you just use the CLI to create a text file in a directory and configure the settings for it. It's rather simple once you have the information. So give google a try and search for adding a nic in debian.

You may also want to consider NIC bonding via LACP and splitting the networks via vlans.

Someone correct me if I'm wrong.

I have successfully separated client side network from NAS network. I yet have to run some test to see how much faster it makes my client network specially during backup. But overall it looks pretty good so far.
Thanks to Spirit and SysFailure0x5a for pointing me right direction!
