What is Vmware EVC and How do we use it ?
Quick and Rough Notes!
- It's feature implemented on Cluster Level
- Clusters are vCenter server Objects and they to contain number of VMware Hosts you manage
- Vmotion is feature most widely used to migrate Vms across hosts as needed
- But you cannot migrate VMs across any hosts as you need.
- There are certain rules, you can only migrate Vms across hosts only if the x86 processors used by hosts are Vmotion compatible
- Two hosts / processors are termed to be vmotion compatible if you can successfully migrate Vms across them
How do I know if two processors are vmotion compatible ?
Check out KB : VMotion CPU
compatibility requirements for Intel processors : http://kb/kb/1991
Ok, now I found my hosts are not vmotion compatible, what next ?
- This is where you go for Vmware EVC
- Which stands for Enhanced vmotion compatibility
- There are different modes of EVC
- You need to choose the mode which suites your environment, CPU family on the hosts in cluster
How do I know which mode to go with ?
Check out KB Enhanced vMotion Compatibility (EVC) processor support : http://kb/kb/1003212
I have some doubts and few questions on EVC, is there any good Kb which
discussed about it ?
Check out : EVC and CPU Compatibility FAQ : http://kb/kb/1005764
The information shared is keeping fresher or beginners in mind or to
give an overview of EVC.
One most important thing which you should know when you say I know EVC
is ?
You cannot enable EVC when VMs are on and running on hosts
