How does one capacity plan with the new GPU functionality? For example, say I buy a new Dell PowerEdge R720 w/ nVidia GRID K1. The K1 has 4 GPUs and 16GB RAM. The R720 itself can have 384GB RAM in a reasonable price config using 16GB dimms. If I deploy Windows 7 VMs with 4GB RAM each for AutoCAD (or whatever), would that much system RAM be a complete waste as the GRID K1 could only support 32 (see below) GPU-enabled VMs?
For my example, I assumed the number of VMs would be limited by the 16GB GPU memory split between VMs configured with 512MB video memory.
