How to enable VMware EVC on VMware vSphere & VI3 without downtime
If you don’t know what is VMware EVC or you need to find out more about it, please look at my last post VMware EVC enhanced VMotion Compatibility enable VMware VMotion across CPU generations
Ok, if you had read that and now wondering how to get it setup without having to shutdown your virtual machines. Then this small tip is for you.
As you know & I had mentioned that in my previous post on this topic that VMware will request you to shutdown all the virtual machines you have running on the cluster you want to enable VMware EVC for. To avoid having to shutdown your virtual machines what you can do is to create a temp cluster with few temp servers on it & VMotion your VMs to these servers. Enable VMWare EVC on your evacuated production cluster. Then again VMotion the Virtual Machines back to your original production cluster.




i need to build a 2 server cluster to host a frontend virtual machine.
the virtual machine should run on 1 node(most powerful) and in case of hardware/software failure run on 2 node (less powerful only for services availability, reliability)
should i use vmware or hyper-v for best costs/Reliability ratio?
thanks in advance.
As reliability go I would say VMware can beat hyper-V at any time, specially they have been out there for a lot longer & running in many production environment. I know many members of our team will argue on this, but if you come to me I would always implement VMware over Hyper-V when a critical application is involved.
