NLB node dropping out of cluster | server 2012 | vmware
Hi,
i have an environment that is
3 x server 2012 servers
each server is a DC
each server has a web application running on it
each server has 2 vnics
For whatever reason, unknown as yet, one of the servers keeps dropping out of the NLB cluster and has to be restarted.
The NLB cluster is currently configured in unicast mode.
in this environment, a vswitch has been configured for the nlb vnics. I cannot find any vmware guidance that this should be done. The issue was happening before this configuration was implemented.

Unicast to Multicast is a BIG change, can your physical switches support Static Arps ?

continue to use 2 vnics but change the operation mode to multicast?
