Hyper-V 4-part Cluster Problems/Performance:

Just a heads up to a MUST READ series for those using or thinking about using Hyper-V. Techtarget has a 4 part series on Cluster problems and workrounds/solutions to some of them. You will see many times Hyper-V manager is used and not SCVMM to fix the issues. Perhaps hacking a clustered file system was a bad decision instead of developing a purpose driven shared file system like VMware did with VMFS. I'm not hear to judge though, but more to welcome you Hyper-vers to the world of virtualization and share important knowledge.

Of course I would highly encourage you to take a look at vSphere 4. It is an amazing product.
