Windows 2008/2012 Server OS only supported on WS460c as Hyper-V server. *** Concerning Linux pass-through GPU support • VMware only supports vDGA on Linux for DirectPath I/O (GPU compute) • Citrix does not formally support GPU pass-through on Linux • Neither VMware View nor Citrix XenDesktop support brokering Linux desktop at this time XenServer Multi-GPU pass-through considerations • GPU pass-through technology allows for maximum graphical performance (Workstation grade) as each VM has a dedicated GPU attached • XenServer only supports passing through only 1 GPU per VM • When creating a VM with workstation class graphics performance, you will also need to give it workstation class resources with at least 2 vCPU and 2-4 Gb memory • GPU to VM density determined by number of GPUs, this model uses one GPU per VM, no sharing Citrix XenServer NVIDIA GRID vGPU considerations • Each physical GPU can be split into 2 or 4 vGPUs • NVIDIA GRID K1 and K2 cards have multiple GPUs per card: GRID K1 has 4 K600 level GPUs with 16 GB of vRAM and GRID K2 has 2 K5000 level GPUs with 8 GB of vRAM • At time of this writing, the predefined GRID vGPU are as follows, only same type vGPUs can be used on the same physical GPUs (table 4) Table 4.
