I currently have an Unraid server at home that runs a bunch of docker containers for various home use things like a nextcloud server, jellyfin, audiobooks, game servers. I work at a veterinary clinic and we have a windows server that runs our PIMS software and some network shares. We would like to put computers in each of our exam rooms. The problem comes because we have a CT machine that takes pretty significant graphical and CPU power in order to run the reconstructions in order to view the scans. We could just buy a high end desktop for each room, but that seems like it would be fairly expensive and not very expandable. The other option that we have discussed is purchasing another server (or building it) and running one or multiple VM's to be able to allocate resources and just run a very small bare-bones computer in each exam room and connect via RDP to a VM on the host machine. I have 2 major options from here, run a single VM that is dedicated only to viewing CT scans, but can only be used in one room at a time, or running a VM for each room and running very bare OS for RDP and doing all computing on the VM. From what I can find however it looks like on unraid GPU's can't be shared between VM's running at the same time. I have considered doing something like VMware, or another hypervisor, but there are other docker containers that I think would be useful to be run on the same server. Any thoughts?
