We are upgrading Jive SBS 4.0.13 to 4.5.3 and would like to run a 3 node voldemort cluster, however, we would like to have each node run in parallel to a Jive App Server on our hardware. At this time we are not moving to a virtual environment and would like to run on the existing hardware.
DB: Oracle RAC 3 node cluster
App Servers 1-8 (16 CPU, 96Gb Ram): 1 Jive App Server (currently running at less than 5% CPU and less than 5% ram)
Proposed 4.5 environment:
DB: stays the same
App Servers 1-5(16 CPU, 96Gb Ram): 1 Jive App Server
App Servers 6-8(16 CPU, 96Gb Ram): 1 Jive App Server, 1 Voldemort Node

- Cache server on a machine separate from clustered application servers.
If you're setting up more than one cache server machine, you should use three or more. Using only two cache servers can be less efficient than using one.
Can you please provide a precise explanation of why this statement was made so we can determine if our proposed topology is ok, if the reason is simply server resources, we should be ok, if it is something else, we need more details to make that decision.
