Hi Ricky, I think that completely depends on Logical processor supported by hypervisor. Xenserver supports 150 Logical processor per hosts. So as far as hypervisor limit is satisfied cluster works fine.
Thanks, Tejas From: Ricky Keele <[email protected]> To: [email protected] Date: 11/13/2014 07:58 PM Subject: Re: Hosts per cluster? I have another question to add to that same question. Does this change with how many cores a host would have? Example you have host with 8 cores, so 8 of those x 6 would be 48 cores running. What about with 32 cores? So 6 of those x 32 would be 192 cores. Which part determines how many that you can have.
