    Mellanox Switch HA vs Two independent Switches

    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...
