Support for Single Root I/O Virtualization (SR-IOV) was first introduced back in 2012 with the release of vSphere 5.1 and enables for a physical PCIe device to be shared amongst a number of Virtual Machines. The networking industry was the first to take advantage of the SR-IOV technology and could be used to help reduce latencies and improve overall CPU efficiencies for vSphere-based workloads that were network intensive.
Since SR-IOV is an extension of the PCIe specification, it can also be used benefit other non-networking devices. In 2016, AMD introduced their MxGPU technology which added SR-IOV capabilities to their GPUs which was then used to power VMware Horizon workloads, but this functionality was only available during the vSphere 6.0 and 6.5 release.
GPU sharing these days are synonymous to one vendor, NVIDIA. In 2015, VMware and NVIDIA teamed up to accelerate Enterprise desktop workloads through the integration of NVIDIA's vGPU (formally GRID) technology with the release of both VMware Horizon View and vSphere 6.0.
NVIDIA continues to dominate the GPU market in 2023, however another vendor has re-entered the market with an interesting solution that is enabled by the latest vSphere 8.0 Update 2 release ...
