Mellanox Switch HA vs Two independent Switches

[gm-service]

After we deployed our proxmox cluster (4 nodes with additional chrono on backup server), we quickly discovered that existing unifi switches were not up to the task. Overall this is a really nice (though sometimes frustrating) experience for me.

Lucky enough we came across two used SN-2010 at a customer installation and I have some questions that I struggle with (Mellanox is entirely new to me, as are ONIE related topics).

Q1: how I imagine it the setup would be the following:

VLAN 10: Cluster communication and Chrono L2 LACP two cables one per switch
VLAN 20: Storrage L2 LACP two cables one per switch
VLAN 30: Backup L2 LACP two cables one per switch

Both switches are connected with an additional VLAN directly on the 100gbe port with two cables.

Is that a feasible setup or am I misunderstanding anything?

Q2: Can the above setup be configured and maintained via WebGUI of Onyx?

Q3: If it can not be maintained via web, we need to get used to ssh configuration of switches anyway, which OS should I go with?

You would have to put the switches into an MLAG configuration, otherwise it will not work properly

Q2: Can the above setup be configured and maintained via WebGUI of Onyx?

You probably could, but I recommend against it. Documentation is about CLI.

Q3: If it can not be maintained via web, we need to get used to ssh configuration of switches anyway, which OS should I go with?

Cumulus Linux. Onyx for Ethernet is End of Life and only receives security patches.
