Multiple NICs and bridge setup

[jms]

I have inherited a proxmox installation and need to rebuild ti but I am trying to understand the networking side of things.

There are 3 nodes in a cluster, a management node with the templates etc., and two compute nodes for the VMs and each node has 4 NICs.

The private network for the cluster and the storage network are assigned to the physical ethernet NICs.

The management network and the public network for the VMs have been assigned to bridges.

I can understand why the VMs need a bridge but don't understand why the management network needs one.

Is there a specific Proxmox reason to have the management network using a bridge and is there a best practice for this type of setup ?

Many thanks

Thanks but that wasn't really my question.

I understand that you need a bridge at least for the VMs, I was asking why the management network also used a bridge and why the storage network didn't.

It just seems a bit random and was trying to understand if there was a specific reason or any best practices.
