Load Balance Multiple Clusters

[imchaser_]

I have 1 SA6000 Active/Passive Cluster and 1 SA4000 Active/Passive Cluster, each cluster has licensing for 1,000 users.  I would like to combine these clusters to allow for 2,000 users to access via 1 URL, is anyone aware if this is possible?  I have an F5 BigIP available for load balancing if that will work.

Thx

We do just what you are suggesting, though we also recently eliminated active/passive clustering, and let the F5 do all the work of failover as well.  We didn't find that the value of A/P clustering outweighed the complexity it created.

We currently have 8 6000/6500s behind a F5 LTM in 3 different pools (3 different URLs for different uses of the SAs).  Source address persistence is important - we use a persistence timer of 60 minutes.  That seems to work OK, though I think we could take it down to 20 minutes (our rekey interval).

Should work fine, if your using: Load balancer persistence (sticky session).
