Creating a JRun/CF cluster and using hardware load balancing
I am creating a hosting environment that will consist of a Hardware load balancer (CISCO CSS), 2 Windows 2003 Server Machines running IIS6 and JRun/Coldfusion. Will will also have a remote storage machine (NAS) to hold all the client data and store the websites.
What I need to know is - if I want to use session replication across the two server machines, am I able to create a JRun cluster across the two so if one fails the other will maintain the session state? Or does this conflict with how the CSS with balance the load. i.e. will the CSS direct me to one machine only to have the JRun/CFusion decide which server in the cluster to use?
Im a little confused as to how JRun should be setup when using a hardware load balancer.

This solution is only available to members.

Use client variables stored in a database rather than session variables, this will maintain your sessions across all servers.

I'd like to note that we are using the exact same setup including the css, and there are a few problems with it concidering the failover part I have not a bug submitted at Macromedia and they are looking in to it, for now the failover is not working so concider that before making this setup

If I use the hardware load balancer in front of two machines running multiple instances of JRun/CF, should I cluster all the instances across both machines or should I have sepecrate cluster on each of the boxes?
Assuming it is best to create a cluster with all instances from both machines - do I need to register remote servers and create the cluster through the JMC on both machines or just on one so that IIS6 (one install per machine) can be connected to the cluster from both machines?
Thanks again
