Heya,
I've got a 2013 Mac Pro I am trying to run up as a VMware ESXi host. The problem is that both dGPUs (D500s) in the system are running at full power, so the idle power draw is around 117W. If I try to assign the secondary GPU to a VM via VT-D, I can get that down to around 77W.
But I can't assign the primary GPU to a VM, nor can I do direct PCI-E passthrough on it for a guest VM. When running macOS natively, idle use is around 47W. I'd expect the same, or less, with ESXi running idle.
Is there any way I can shut down the GPUs in this thing to get my power usage down?
