Zenoss Core 5 Redundancy / failover

Hi,

I am currently running two Centos 6 Boxes as a high availability cluster using Corosync, drbd etc.. so if one node fails my zenoss 4.2.5 instance cracks on doing its thing.

My quick question is, of which I would be very grateful, if i decided to move over to Core 5 can I and do I do the same thing and create a HA cluster, then install control centre & docker then zenoss on each node

Or is there only ever one instance of the control centre and then its only the hosts in the resource pool that are redundant (assuming you have two or more)

Thanks for your time, and I look forward to hearing from anybody :-)

Rgds,

Nik..
