Unicast v Multicast in Windows 2008 NLB
Posted on 2009-04-04
I am setting up a Windows 2008 server NLB, and there is the option of setting up the cluster operation mode in Unicast or Multicast.
This is slightly complicated by the fact that both the cluster nodes are virtual servers (Vmware ESX guests) running on the same ESX host, which itself is an HP Blade server connected to our Cisco switches via Virtual Connect modules!
Can anyone advise which option is best in this case - Unicast, Multicast or IGMP Multicast?
