If you have not deployed Community Server multiplexers on separate machines, you have two choices for setting up the load balancing mechanism.
- Set up a rotating DNS system to accomplish load balancing. Use rotating DNS to associate the IP addresses of the Sametime® server machines to a single DNS name.
For example, associate the IP address of Sametime server 1 (22.214.171.124) and Sametime server 2 (126.96.36.199) to the DNS name cscluster.sametime.com.
- Set up an IBM® WebSphere® Edge Server (Network Dispatcher) in front of the Sametime servers that you intend to cluster. Use the WebSphere Edge Server Network Dispatcher to distribute connections to the Sametime Community servers. For more information, see the WebSphere Edge Server documentation, available at the website www.redbooks.ibm.com (and also provided with the WebSphere Edge Server).
The diagram below shows the Sametime
servers with the rotating DNS system in place. Note that the WebSphere
Edge Server can be used in place of the rotating DNS system.
