You have a 128 GB server to use as a virtualization host. You have thirty-two applica- tion servers that you plan to P2V to this host. Each application server is currently on a physical server that has 6 GB of memory. The application servers all run Windows Server 2012.

?? Without taking advantage of any memory optimization techniques, what is the maxi- mum number of virtual machines you can host on your server?

?? With page sharing and ballooning you can take advantage of memory overcommit. If you overcommit memory at a 1.25:1 ratio, how many virtual machines can you now host?

?? While gathering baseline performance metrics for the move to the virtual environment, you find that on average, each system is actually using only 1 GB of memory. Keeping the same overcommit ratio, how many virtual machines can be hosted?

?? You decide to leave some additional memory available for growth or emergency. At a 90 percent utilization limit, how many virtual machines can you have?
