未经许可的模式中缺少功能

目前,对于我的一位客户,我正在为新的XenApp主机编写新硬件设计。
其中一个要求是用于图形加速的GPU。
所有XenApp用户都是任务/知识工作者。
我是GRID解决方案的忠实粉丝,但GRID 2.0 / 3.0中许可组件的额外成本并不能让我的客户满意。
我想知道如果从M10到4未经许可的模式中缺少功能个XenApp VM配置4个GPU的直通,哪些功能将会丢失。
据我在屏幕截图中看到,有一个名为“Tesla unlicensed”的许可模式。
该模式有哪些限制?
我只需要Office& amp;的图形加速
在具有2个FHD显示器的瘦客户机上运行的Web浏览器......
感谢您的回复!

Currently for one of my customers I'm writing a design for new hardware for new XenApp hosts. One of the requirements is an GPU for graphics acceleration. All XenApp users are task-/knowledge workers.

I'm a great fan of the GRID solutions but the additional costs for the licensing component in GRID 2.0/3.0  doesn't make my customer happy.

I'm wondering which features will be missing if configuring a passthrough of the 4 GPUs from a M10 to 4 XenApp VM's. As far as I saw in screenshots there's a license mode named 'Tesla unlicensed'.
What are the restrictions of that mode?
I only need graphics acceleration for Office & web browsers running on a thin client with 2 FHD displays...

Thanks for your reply!

pdf“GRID LICENSING DU-07757-001 _v4.0(GRID)| 2016年8月”,“第3章。
带有PASSTHROUGH的许可网格虚拟工作站“明确定义 -
未经许可的Tesla GPU支持单个虚拟显示器头,最大分辨率为2560×1600。

嗨,asg,
显示器头与没有。
对于XenApp来说,显示器有点不同......有几个博客可能有所帮助 - 如果有差距,请告诉我......

https://virtuallyvisual.wordpress.com/2016/09/05/nvidia-grid-rdsh-licensing-including-xenapp/
这有帮助吗?
我们希望将博客信息汇总到文档中。
更好。
最好的祝愿,
雷切尔

Hi asg,

the display heads vs. no. of monitors is a bit different for XenApp... there are a couple of blogs that might help - let me know if there are gaps...

Does this help? We are looking to roll up the blog information into the doc. better.

Best wishes,
Rachel

感谢mcerveny和Rachel的回复。
我已经阅读了许可相关指南并看到了'特斯拉(未经许可)模式'。
不幸的是,我不清楚这种未经授权的模式究竟意味着什么以及后果是什么。
未经许可的GPU是否通过XenApp服务器无价值?
换句话说:GPU对图形性能没有任何影响吗?

Thanks mcerveny and Rachel for your replies.

I'd already read the licensing related guides and saw the 'Tesla (unlicensed) mode'.

Unfortunately it isn't clear to me what this unlicensed mode exactly means and what the consequences are.

Is an unlicensed GPU passthrough'd to a XenApp server worthless? In other words: does the GPU hasn't any effect on graphics performance?

你好
除了上面提到的单一显示器和显示器分辨率限制之外,您的客户是否考虑了他们将从哪里获得M10驱动程序,如何在发布新驱动程序时升级/维护这些驱动程序以及他们如何监控和支持GPU?
目前,M10驱动程序似乎无法从可公开访问的Nvidia驱动程序下载页面获得,这显然使得入门有点棘手。
他们是否会在某个时刻,我不确定。
我在论坛上看到了无数的线程,询问他们在哪里得到了早期版本GPU的支持,原因有多种,通常是K1 / K2卡。
答案总是“回到你从哪里购买”,这通常是合作伙伴/转售商,可能没有客户解决问题所需的深入知识和技能,即使他们这样做
,他们是24x7吗?
我知道你的客户显然是在努力降低成本,但是SUMs值得拥有。
由于这些GPU将在Passthrough中运行,因此Hypervisor无法真正看到它们,并且由于您的客户端不会在Hypervisor中安装驱动程序,因此他们必须从各个VM中监视它们,而不是通过
虚拟机管理程序。
跟踪GPU利用率以获得规模/性能虽然显然可行,但并不容易。
只是出于兴趣,是您的客户不喜欢的物理GPU的成本,还是许可模式的成本?
问候

Hi

Apart from the single monitor and display resolution limitations mentioned above, has your client considered where they will get the M10 drivers from, how they will upgrade / maintain those drivers when new ones are released and also how they will monitor and support the GPUs?

Currently, the M10 drivers do not appear to be available from the publicly accessible Nvidia drivers download page, this obviously makes getting started a little tricky. Whether they will be at some point, I'm unsure.

I have seen countless threads on forums asking where they get support for earlier version GPUs for a wide variety of reasons, usually these are the K1 / K2 cards. And the answer is always, "Go back to where you purchased them from", which is typically a partner / re-seller who may not have the in-depth knowledge and skills your client needs to resolve their issue, and even if they do, are they 24x7? I know your client is obviously trying to reduce costs, but SUMs is worth having.

As these GPUs will be run in Passthrough, the Hypervisor can't really see them, and as your client won't be installing a driver in the Hypervisor, they'll have to monitor them from within the individual VMs, rather than through the Hypervisor. Tracking GPU utilisation for scale / performance, although obviously possible, won't be so easy.

Just out of interest, is it the cost of the physical GPUs your client doesn't like, or the cost of the licensing model?

Regards

Ben
