I don't understand why Microsoft virtually diminishes the value of the R2 release. I bet that many people out there perceive R2 to something like a Service Pack, which is mostly about bug fixes. However, Server 2008 R2 has quite an improved performance and feel to it!

 

 

Support of clustering and "live migration" of virtual machines are very important functionality. But even something "small" like the hot add/remove of SCSI disks is a great value to administrators.

 

I sure don't like everything that comes out of Redmond, but Hyper-V had a quality level way above MS average from the start, and the team is continously getting it better and more complete. Good job guys!
