create load balancing on a proxmox server

[zeverybest]

Hi

I'm re building my proxmox server

due to a server failure, I have to rebuild it

on my server, I have 4 ethernet socket

when I'm installing Proxmox, it ask to select one of them

how could I modifiy setings to use my 4 ports to create load balancing (to get more flow) ?

many thanks for your lights

Let it install, then go and edit your /etc/network/interfaces file to create network bond.

https://pve.proxmox.com/wiki/Network_Configuration

auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

auto bond0
iface bond0 inet static
bond-slaves eno1 eno2
address 192.168.1.2/24
bond-miimon 100
bond-mode 802.3ad
bond-xmit-hash-policy layer2+3

auto vmbr0
iface vmbr0 inet static
address 10.10.10.2/24
gateway 10.10.10.1
bridge-ports eno3
bridge-stp off
bridge-fd 0

oh, thanks for your quick answer

but, it would say I cannot use the same IP address?

I have to use a new one for the BOND connection?

correct?

and, could it be on the same VLAN ? (I would say same VLAN than vmbr0?)

Bond connection will only combine interfaces at the data link (layer 2) level, it will basically work like "one powerful NIC"

 

[zeverybest]

OK, so, it could be on same VLAN
but I have to use differents intefaces from vmbr

one interface cannot be in both?

correct ?

The only thing that needs an IP address is the actual Proxmox web interface. You could add a bridge or a bond without adding anymore IP adresses. A bond or a bridge on its own doesn't actually need an IP address because the VMs or lxc containers all get their own up addresses

 

[zeverybest]

yes, but to create a BOND, i need to connect to proxmox with current IP on vmbr0

so, I cannot use same interface to add to BOND (or, I have to do it localy, not remotely)

correct ?

 

[louie1961]

You have two choices I think. First you could leave the management interface on one NIC and bond the other three. OR you could log in through the console if you have a monitor and keyboard attached to the server, and manually adjust the /etc/network/interfaces file, create the bond using all 4 NICs, make it VLAN aware then put your management interface as a virtual NIC to the bond.
