Sizing the memory for the servers hosting the virtual desktop machine is somewhat easier than the CPU, although you might need to play a balancing act with the chosen server. The reason for this is that, just because it can accommodate the number of desktops from a CPU perspective, it might not have the memory capacity to serve that number.
If you take a virtual desktop that requires 2 GB of memory and look at the light user scenario from the previous section as an example, you would be hosting 141 virtual desktop machines. That means that the host server will need 282 GB of memory just to host the virtual desktop machine, plus enough memory to run the hypervisor too.
