带有网格K2的Windows 2016 Server是否可以在各种VM上使用？

你好
我不是帮助您使用Remote FX的合适人选（从未使用过它）。
但是，本指南的第4页将帮助您了解K2配置文件：http：//images.nvidia.com/content/grid/pdf/GRID-vGPU-User-Guide.pdf
每个K2最多支持16个单独的会话（每个GPU有8个会话，每个板有2个），但每个会话只有512MB的帧缓冲。
因此，对于Windows 10 / Server 2016，这实际上不够好。
对于Windows 10，理想情况下不亚于K240Q配置文件（1GB）。
使用服务器中的2个K2板（4个GPU），您将获得16个Windows 10会话。
如果你想要更多，那么你最好在Passthrough中使用RDS和GPU。
术语“直通”是指通过虚拟机管理程序将物理设备（在本例中为GPU）传递到VM的位置。
执行此操作时，没有其他VM可以使用该硬件。
它是1：1的比例。
通过Kepler GPU，Passthrough确实提供了一些额外的性能，访问CUDA和更高的分辨率（高达4K）。
您也不需要在Hypervisor中安装驱动程序。
使用更新的架构，Passthrough的好处略少。
例如，使用单个K2，您可以在Passthrough中运行1x GPU并将其分配给RDS主机，而另一个GPU可以切换到4x K240Q Profiles。
不要忘记，尽管使用了GPU，您仍然需要在所有VM之间平衡CPU，RAM和磁盘IO。

Hi

I'm not the right person to help you with Remote FX (Never used it). However, Page 4 of this guide will help you with K2 profiles: http://images.nvidia.com/content/grid/pdf/GRID-vGPU-User-Guide.pdf


Each K2 will support a maximum of 16 individual sessions (8 sessions per GPU of which there are 2 per board), but each session will only have 512MB of frame buffer. So for Windows 10 / Server 2016, this won't be really be good enough.

For Windows 10, ideally nothing less than a K240Q profile (1GB). With 2x K2 boards in your server (4x GPUs) you'll get 16x Windows 10 sessions. If you want more than that, then you're best off using RDS with the GPUs in Passthrough.

The term "Passthrough" is where you pass the physical device (in this case a GPU) through the Hypervisor and into a VM. When you do this, no other VMs can use that piece of hardware. It is a 1:1 ratio.

With the Kepler GPUs, Passthrough does offer a little extra performance, access to CUDA and a higher resolution (up to 4K). You also do not need to install a driver in the Hypervisor. With newer architectures, the benefits of Passthrough are slightly less.

As an example, with a single K2, you could run 1x GPU in Passthrough and assign it to a RDS host, and the other GPU you could slice in to 4x K240Q Profiles.

Don't forget, you still need to balance out CPU, RAM and Disk IO between all your VMs, despite the use of a GPU.

你好
感谢您的回复，感谢您的帮助。
如果它只能在一个虚拟机上使用，那么我真的没有看到GPU的重点。昂贵的解决方案。
也许有一些用例。
我的目标是使用Hyper V在Win2016服务器上使用K2卡提供win10 VM。整体体验很好，但我发现视频播放有时可能会被点击或错过，如果可能的话，我试图解决这个问题。
我知道RDP上任何类型的视频播放一直存在问题，但Windows 2016 RemoteFx已经有所改进。
谢谢

Hi

Thank you for the reply, appreciate the help. I do not really see the point of GPU pass through if it can only be used on one VM, expensive solution. Maybe there are some use cases for it. My aim is to deliver win10 VM's using K2 Cards on Win2016 server using Hyper V. Overall experience is good but i find video playback can sometimes be bit hit or miss and that is the bit I am trying to fix if possible.
I know video playback of any sort over RDP has always has issues but Windows 2016 RemoteFx has improved.

Thanks
