VMware's DRS with vmotion is amazing technology. I'm not a fanboy, either. We thought about using Hyper-V for dev/qual because.. that is about the only place it makes ANY sense in the enterprise. With 240 VMs we have to worry about a process kicking off and using up a lot of resources on a server. When that happens vmotion with DRS migrates things around and load balances very quickly. Interesting enough, with Microsoft doing the jig here.. that soon as they have this feature, it'll be the best thing since sliced bread. With all the bullshit talk, don't think they're not working on getting it done too. Its very necessary, except when you don't have it and are trying to sell something without it.

I never expected them to compare their technology to vmware's in a decent way, but this is by far the worst comparison i've seen in years. As if any decent system engineer would wait till the evening to replace defect hardware. Especially when you have an 8:1 consolidation ratio. I don't think so. It’s just another marketing campaign.

They do that stuff all the time hoping people are stupid. If you didnt use Vmotion during the course of a business day you couldnt add hosts to a VMware HA cluster during business hours. Because once the host is added the VM's would start to muigrate, Live, as it balances resources in the cluster. We move VM's all the time with Vmotion during the course of the day. Users don't even notice. Even if connected to the VM with RDP. I take any MS says with a grain of salt. They tend to make it up as they go along and dont care if they are right or wrong.
