Feature by feature comparisons of Hyper-V in both Windows Server 2008 R2 and 2012

I just went looking for a decent comparison of Hyper-V in Windows Server 2008 R2 and Windows Server 2012.  I obviously found this excellent document on download.microsoft.com – but couldn’t find these high-level bullets anywhere.

Hence this post:

Hyper-V is available as both the FREE Hyper-V Server 2012 and as a role in Windows Server 2012.

If you are virtualising Windows Server workloads (and have licensed them correctly), Hyper-V is completely “free” – so save yourself a lot of money by NOT purchasing an additional virtualisation solution.

    The Server Message Block (SMB) protocol is a network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network. The SMB protocol can be used on top of its TCP/IP protocol or other network protocols. Using the SMB protocol, an application (or the user of an application) can access files or other resources at a remote server. This allows applications to read, create, and update files on the remote server. It can also communicate with any server program that is set up to receive an SMB client request. Windows Server 2012 introduces the new 3.0 version of the SMB protocol
