For the last 10 years I have been using Proxmox I have not have a lost
connection to a server for over 1 sec without it being intentionally
but if your circumstances is another usecase I would go for stackable
switches I have a port for either switch connected to my servers and
UPS control for all my servers.
Loosing connection to a server for more than 1 sec can only mean
hardware failure or loss of power.
Forgot to mention that all my infrastructure and hardware is UPS
controlled so only planned downtime has been when replacing UPS/battery
in UPS (3 times) and one time when there was a longer period without
power from the power grid (1 time and not planned ;-).
Unfortunately, starting with PVE 7.x we're seeing cluster issues (nodes
going out of quorum only to rejoin instantly) "too often".
This is why we create multiple links for corosync after upgrading
clusters to v7, so that one of these point-in-time issues with network
doesn't reboot a node.
So far it has worked well. Unfortunately, we haven't been able to find a
common pattern/cause in several clusters we see the issue.
