Max number of Nodes when using Unicast

[masterdaweb]

Hi,

I read in Proxmox Documentation and it suggests not using more than 4 nodes when using Unicast.

If i'm not using a HA Cluster, in other words, if my nodes runs at most isolated one from each other, what problems in specific Unicast could lead us ?

The problem with unicast is the exponential rising amount of packets when you add an node.
This packages makes an massive load on the network.

Hi @wolfgang,

What happens when a node is added ? I didn't get your point.

Lets assume that I'm not using HA, why network could be overloaded when a node is added ?

Your switch will get slower and you lose quorum all the time.

Because the packages behave exponential by number of nodes

Depends on your switch. We're using far more then 4 nodes with unicast without any problems here in HA mode.
