Red Hat Enterprise Virtualization Manager (RHEV-M) Scalability and Maximums
What is the maximum number of physical hosts that can be managed by a single RHEV-M instance? 200 is what I have for max hosts per cluster. What is the scalability limit if I have multiple clusters?
What is the maximum number of virtual machines that can be managed by a single RHEV-M instance?
Are there any differences in the scalability limits in a Self Hosted Environment vs. a non-Self Hosted Environment?

Dave,
The maximum number of VMs depend upon their lifetime. Many, short-living VMs require many "transactions" from RHEVM and the SPM(s). The cpu/memory of RHEVM system and the I/O-bandwidth of the SPM(s) determine the number of VMs you can handle.
In a self-hosted environment some capacity of one of your hypervisors is used to run a RHEVM instance. This will reduce the amount of VMs for that particular hypervisor.
