IN preparation to try and use VM for SharePoint 2010 migration, my VM infrastructure team has asked me how the SharePoint servers communication with each other.
The main thing they want to know is if the communication is Uni-Cast, Multi-cast, or something else?
The only thing I have found online is this reference
"Note that when load-balancing the front-end servers, keep in mind that NLB operating in unicast mode with a single NIC will prevent inter-host communications, possibly interfering with the functionality of the farm. In this situation, it's usually best to implement the NLB cluster in Internet Group Management Protocol (IGMP) multicast mode (provided your switch vendor supports this). Alternatively, you can use a third-party hardware load-balancing solution."
Does that mean they communicate in multicast mode?
