NLB cluster: Single Host vs Multiple Host with Single Affinity

Question

Hello,

Can somebody (pin-?)point the differences between Single Host vs Multiple Host with Single Affinity. They seem to be similar in a way. Also: What configuration needs to be done on IIS SRV concerning NLB cluster?

Thanks!

Hi ,

Single host :This parameter specifies that network traffic for the associated port rule be handled by a single host in the cluster according to the specified handling priority. This filtering mode provides port specific fault tolerance for the handling of network traffic.

Single affinity refers to load balancing based on the source IP address of the incoming connection. It automatically redirects all requests from the same address to the same cluster member.

If you are using network load balancing and you want to direct multiple requests from the same IP address to the same cluster host, then you need to use Single Affinity.

For more details, please refer to the following article:
