Apparently Microsoft’s new Hyper-V product is not compatible with NIC teaming. I hope Microsoft quickly resolves this as not being able to team NICS to provide redundancy in 24/7 servers is a big issue.
Also another area where Microsoft seems to be deficient is with Quick Migration. VMWare’s VMotion allows you to quickly migrate a virtual machine to another ESX host so you can perform maintenance on the original host. Microsoft’s Quick Migration should enable the same thing but people have been running into major issues with it as the process has caused some issues causing administrators much grief.
I recently have spoken with many people who are going the Hyper-V route because it’s “free”. I have to argue that now that VMWare’s ESXi is free, people really have no excuse not to go with VMWare based on their proven track record in the industry. These people are quick to point out the recent debacle with Update 2 but then you can’ t tell me that Microsoft hasn’t royally screwed up a patch in the past either. At the end of the day I still say that VMWare is your best bet at this point in time to keep your servers running smoothly.
