if you have a virtualization server with 128GB of physical memory and you plan to virtualize 32 application servers running 6GB of memory each, all running Server 2012 R2, answer the following:

1. Without taking advantage of the memory optimization techniques discussed this week, what is the maximum number of VM you can host on this server given that the OS and hypervisor overhead utilizes 2GB of memory?

2. With page sharing and ballooning the hypervisor can utilize memory over-commitment. If you over-commit memory at a ratio of 1.25:1, now how many machines can be hosted?

3. You decide the host OS needs an additional 20% of memory resources (2GBX1.2). Given your answer for number 2, how many fewer VMs can run on the system?
