[pindaroli]

Hi all, I have two proxmox node with 2 nics free each, in the first is hosted opensese vm, how i can without a smart switch (i have a chinese cheap 4 port hub) to bond the two nics of each node?

Thanks

You cannot use a hub to do bonding / link aggregation. The link partner has to support LACP.
The only option is to use the active/backup mode (not 802.3ad) and then only utilize one of the two NICs at a time.

Thanks , but in one node i host OPNsense, can i useit to implement "the server side" of link aggragation normally implented by switch?

If you directly link both Proxmox nodes with two cables without the hub you can configure normal bonding interfaces between them.
There is no "server side" with LACP, just two Ethernet partners talking to each other.

I this case i prefer to use the other link for clustering of proxmox

Yes

Yes

But is needed a switch in the middle? is it mandatory?

 

[gurubert]

no, you can link both Proxmox nodes directly
