Hey, So I am coming from the enterprise world and pretty new to UNRAID, in the past have deployed tons of VDI solutions using the main stream vendors (VMWare, Citrix, ect), however have a small project for a friends small business and want to help him out. I can get my hands on some used enterprise servers. The main use would be to deliver around 20-25 Windows 10 virtual desktops via RDP to his staff, + 2 Windows Server 2019 VM's. I am currently speccing the following: DELL R730 with: 2 x E5-2670 V3 CPU (12 physical cores, 24 logical cores) 256GB DDR4 RAM 8 x 1TB SATA SSD in RAID 5 (or JBOD) 2 x 750W PSU 1 x Dual Port 10GB SFP+ NIC Now my question is, I have the PCIe slots and space to put in 2 x NVIDIA TESLA GPU's, however will UNRAID be able to "Share" the GPU's to all the VM's? Is all the hardware compatible with UNRAID? Is there a physical processor limit to UNRAID? (as there is also a 4 socket 80 physical core server available for not much more) Is it possible for 2-4 NVIDIA TESLA GPU's to be supported by UNRAID? Is it possible to configure hardware RAID, and then pass that logical volume to UNRAID? Thanks in advance and I really appreciate any help.
