[rhos-list] Capacity Planning

[Ted Brunell]

Are there guides available to assist in the capacity planning for an OpenStack installation?  I'm looking for something that will say what the best breakout for the nova-services is based on either the number of nova-compute instances or the number of VM instances running in OpenStack.  For example, is there an indicator of when it is best to run the messaging server on its own physical server?  Is that indicator typically met when there are 10 compute-nodes, or 1000 VM instances?

Thanks,
Ted Brunell
