Hyper-V Hosts Limitation in VMM 2012 SP1

Hi

I searched alot to find out the limitations of Hyper-V hosts as well as VMware ESXi Hosts/Citrix XenServer hosts in System Center VMM 2012 SP1.

Pls reply if anybody knows this answer- how many hyper-v hosts, ESXi hosts, XenServer hosts a VMM 2012 SP1 can support upto?

Any help would be really appreciated.

Thanks in advance.
