Hello all,
I have a CAS array for Exchange 2010 configured to loadbalance on my Cisco ACE 47XX. My question is: Can I run a mixed VMware cluster version 3.5 and 4.1 on my ACE? I am experiencing is dropped RPC connections and I was wondering if that could be the cause of it or maybe I am misconfigured something on the ACE
Another question:
Should I seperate the two cluster versions on their own serverfarm and than loadbalance the farms? What I mean is serverfarm 3.5 and serverfarm 4.1 and than loadbalance them.
Thanks

Hi Keith,
As far as the ACE is concerned, there is no difference between a virtualized server and a real one. The only thing it knows is the IP address and port to access them. Therefore, it should not matter if some of the servers are in a VMware 3.5 and some others in 4.1
Regards
Daniel
