vDGA GRID K2 passthrough multi-gpu支持

嗨，
我有3个Dell R730，每个服务器配置2个NVIDIA GRID K2板。
我通过在我的一台ESXi服务器上激活直通模式，将1个GPU专用于VM。
在启动应用程序Image Generator（Genesis IG）时，我注意到我的GPU实际使用率为99％，这解释了一些不太好的性能，它接近常规PC上的GeForce 970GTX所提供的但还没有真正存在
。
为了解决性能问题，我决定在passthough模式下为这台机器添加另一个GPU，现在我已经安装了2个GRID GPUS并显示在我的VM上。
我的问题是，可以让2 GPUS在多GPU支持概念或SLI中协同工作吗？
现在，如果我启动相同的应用程序，我只能看到1个GPU工作，另一个是0％。
单个GPU可能足以运行IG，如果我不必浪费25％的GPU用于PCoIP会话单独进入我的Zero客户端。
谢谢
帕斯卡尔

Hi,

I have 3 x Dell R730s configured with 2 x NVIDIA GRID K2 boards in each servers. I have dedicated 1 GPU to a VM by activating the passthrough mode on one of my ESXi server. When launching an application Image Generator (Genesis IG), I have noticed that my GPU was actually being used at 99% which explains some not so good performance, it is close to what the GeForce 970GTX on a regular pc provides but not really there yet.

In order to address the performance issue I have decided to add another GPU to this machine in passthough mode and I have now 2 GRID GPUS installed and showing up on my VM. My question is it possible to have the 2 GPUS working together in a multi-gpu support concept or SLI? Right now if I launch the same application I can only see 1 GPU working and the other one is at 0%. A single GPU would probably be enough to run the IG if I didnt have to waste 25% on the GPU for the PCoIP session alone going to my Zero client.

Thanks

Pascal
