Single Server Network Redunancy

[Mr.Embedded]

Hi All,

My question today is if it is possible to have network redundancy at the server level with proxmox.

For example when you setup a container and your server has multiple network interfaces (also multiple bridges) you are prompted to chose the bridge to be used for routing. I am wondering if it would be possible to setup one of the other available bridges as a network failover in case the main bridge is down.

I could have a proxmox server with 2 network interfaces/bridges with each port being physically plugged into a separate switch. Then I create my vms and select the desired interface/bridge for its use. If the one of the switches die on me, then all the vms that are using the interface/bridge that is physically plugged into that switch will be effectively offline until said switch is replaced/repaired or the interface/bridge selection is manually changed in the container configuration.

But if a network failover mechanism is in place, the proxmox server would temporarily route vps traffic over the good interface/bridge so that there is zero downtime in the event of an issue like this one.

Is there any good way to do what I am suggesting?

Hi,
do you mean trunking (or bonding) like 802.1ad http://www.ieee802.org/1/pages/802.1ad.html ?

Hint: look at System/Network -> create bonding device...

That looks like it could be it. I wonder why I didn't see that before. Thanks
