Introduction A couple of months ago, I began investigating GPU passthrough on my workstation to test ArrayFire on different operating systems. Around the same time, we at ArrayFire found ourselves with a few surplus GPUs. Having had great success with my virtualization efforts, we decided to build a Virtualized GPU Server to utilize these GPUs. Building a Virtualized GPU Server alleviated one of the pain points at our company: We no longer need to swap GPUs or Hard Disks to test a new environment. To maximize the number of GPUs we can put in a machine, we ended up getting a Quantum TXR430-0768R from Exxact Computing which comes in a 4U form factor and supports upto 8x double width GPUs. ...
