Hello from the MMS 2012 in Las Vegas!
Clusters now support up to:
– 32 nodes
– 4000 VMs
– 160 processors per host
– 2TB memory per host
– 32 virtual processors per virtual machine
– 1TB RAM per virtual machine
– Hyper-V Replica can be used for site-to-site replication of virtual machines; it is disaster recovery solution and not a high availability solution
– Hyper-V supports out-of-the-box NIC teaming (LBFO); NICs can be vendor independent
– Live Migrate 60-70 machines at same time utilizing 20Gbps connection Sharing SMB storage for VMs (performance is similar to iSCSI)
– Live snapshot merging; no longer a need to shut down virtual machine for snapshot files to merge
– Data de-duplication support for virtual machines
– No longer a need to export a virtual machine; you can now import a virtual machine without an export configuration file (about time)
– Consistent device naming allows to have hardware vendor tag the NIC so that physical port lines up with the port reported by the OS (cool)
Introduction of Hyper-V vSwitch can be read [here](http://technet.microsoft.com/en-us/library/hh831452.aspx).
Thanks for your time and we hope to catch up with you in the future regarding the great things that System Center can provide for you and your business.
