Other great features include Maintenance Mode, which automates the process of migrating VMs to other hosts for maintenance or upgrades, the improved SAN management, and increased third-party support. You should also note that that you can use VMM to manage more than just your Hyper-V environment. You can also manage ESX hosts through VMware vCenter Server (VMM can manage multiple vCenter Servers). But it cannot manage Citrix Xen Server, although that capability may be coming soon.
But the question is not how good is VMM but when you should consider implementing it in your environment.
From what I can see, once you go beyond a few hosts, you should start looking at VMM. And if you are dealing with a mixed Microsoft/VMware environment, the VMM management tools are worth pursuing. For small and mid-size companies, the VMM Workgroup Edition lets you support up to five hosts with unlimited virtual machines. Anything larger than that (either pure Hyper-V or mixed Microsoft/VMware) should implement the VMM R2 tool, especially if you are running Hyper-V R2.
