How to allocate resources to different groups????

I have a Hyper-V 2012 R2 lab environment. I need to allocate resources to different groups. For example, how can I allocate 60% of hyper-v resources (compute and storage) to group A and 40% to group B. How do I accomplish this? I was thinking that the answer may be Microsoft Virtual Machine Manager, but I'm not sure.
The infrastructure is multiple clustered Hyper-V 2012 R2 servers connected to an EquilLogic  PS6xxx
