RDSH高清媒体的使用需要GPU吗？

嗨SJ，
GPU特别有助于增加浏览和视频播放的用户体验。
- 这种类型的使用需要GPU吗？
- >不是必需的，但希望增加用户体验（更好的FPS，流畅播放......）
- 如果没有，GPU会从CPU卸载这类工作吗？
或者那不起作用？
- >是的，特别是H264的编码/解码，例如可以在GPU上的硬件中完成，这将在视频播放过程中极大地卸载CPU
- 如果我使用GPU，单个RDSH VM是否可以使用多个GPU？
- >不，还没有，但对于RDSH，这不是必要的。
我们建议Tesla M10在一台主机上运行4个VM。
- 如何计算每个用户所需的内存（以及所需的GPU）？
- >你需要计算帧缓冲要求，我们看到RDSH上30-50个CCU的8GB FB使用率，办公室使用率正常，具体取决于工作量
- 每台服务器有多少用户？
- >单个主机上每M10 4VM = 120  -  150个CCU
- 您推荐哪种GPU用于此类用途？
- >特斯拉M10
- 需要什么类型的许可？
- > CCU的vApp许可
希望有所帮助
西蒙

Hi SJ,

The GPU especially helps to increase user experience for browsing and video playback.
- Is a GPU required for this type of use?

->Not required but desired to increase user experience (better FPS, smooth playback...)

- If not, Will a GPU offload this type of work from the CPU? or will that not work?

->Yes, especially Encode/Decode of H264 as example can be done in hardware on the GPU which will extremly offload the CPU during video playback

- If I use a GPU, will a single RDSH VM be able to use multiple GPUs?

->No, not yet but for RDSH this is not necessary. We recommend Tesla M10 to run 4 VMs on a single host.

- How can I calculate the required memory (and GPU required) per user?

->You need to calculate the framebuffer requirements and we see 8GB FB usage for 30-50 CCUs on RDSH with normal office usage depending on the workload

- How many users per server?

->4VMs per M10 on a single host = 120 - 150 CCUs

- Which GPU do you recommend for this type of use?

->Tesla M10

- What type of Licensing is needed?

-> vApps licensing for CCU

Hope that helps

Simon

嗨西蒙，
感谢您抽出宝贵时间回答我的问题。
- 是否需要为浏览器启用“硬件加速”以利用GPU？
我问，因为我在Firefox和Chrome中都启用了“硬件加速”问题。
- 我们有20个分支机构，每个分支机构有5-30个用户，GPU会为他们推荐什么？
- 根据此文档，vApp的最大分辨率为1280x1024，具有更高分辨率屏幕的用户连接RDSH服务器时会发生什么？
- 如果是RDSH，CCU将如何计算？
- 我们希望为HQ和分支机构使用HA许可证服务器的单个实例，但有时HQ和分支机构之间的链接会断开一段时间，它们的vGPU何时会停止工作？

Hi Simon,

Thank you for taking the time to answer my questions.


- Is it required to have "Hardware acceleration" enabled for browsers to take advantage of the GPU?
I ask because I have problems with "Hardware acceleration" enabled in both Firefox and Chrome.

- We have 20 branches with 5-30 users each, what GPU do recommend for them?

- According to this document, the Maximum Resolution for vApps is 1280x1024, what happens when a User with a higher resolution screen connects the RDSH server?

- How will the CCU be accounted for in the case of RDSH?

- We would like to use a single instance of HA license servers for both HQ and the branches, but sometimes the link between HQ and a branch gets disconnected for sometime, when will their vGPU stop working?

- 是否需要为浏览器启用“硬件加速”以利用GPU？
- >当然，否则你不会使用GPU :)不确定你在硬件加速方面遇到了什么样的问题。
很可能是因为你没有GPU atm
- 我们有20个分支机构，每个分支机构有5-30个用户，GPU会为他们推荐什么？
- >如果不了解详细的基础设施，这很难判断。
我想知道为什么会有“本地基础设施”。
期望他们连接到中央XenApp服务器场。
- 根据此文档，vApp的最大分辨率为1280x1024，具有更高分辨率屏幕的用户连接RDSH服务器时会发生什么？
- >不，我们的文档说明最大分辨率是控制台会话。
这与RDP会话无关。
当然，您可以使用更高分辨率和多显示器。
- 如果是RDSH，CCU将如何计算？
- > RDSH上的每个并发用户会话都需要vApp许可证。
- 我们希望为HQ和分支机构使用HA许可证服务器的单个实例，但有时HQ和分支机构之间的链接会断开一段时间，它们的vGPU何时会停止工作？
- >新建立的连接会出现问题。
活动运行会话不受影响。

- Is it required to have "Hardware acceleration" enabled for browsers to take advantage of the GPU?

-> Sure, otherwise you won't use the GPU :) Not sure what kind of issues you're seeing with hardware acceleration. Most likely because you don't have a GPU atm

- We have 20 branches with 5-30 users each, what GPU do recommend for them?

->Without knowing the detailed infrastructure this is hard to judge. I'm wondering why there is "local infrastructure" at all. Would expect they connect to a central XenApp farm.

- According to this document, the Maximum Resolution for vApps is 1280x1024, what happens when a User with a higher resolution screen connects the RDSH server?

->No, our documentation states that the max resolution is for the console session. This has nothing to do with the RDP session. For sure you can use higher resolutions and multi monitor.

- How will the CCU be accounted for in the case of RDSH?

->Every concurrent user session on RDSH needs a vApps license.

- We would like to use a single instance of HA license servers for both HQ and the branches, but sometimes the link between HQ and a branch gets disconnected for sometime, when will their vGPU stop working?

->Issue would occur with new established connections. Active running sessions are not affected.

嗨，
- 实际上，我使用“硬件加速”的问题在于我使用NVIDIA GPU的人员经验，并且没有简单的方法来调试问题，唯一的解决方案是禁用它。
- 分支机构将拥有自己的服务器，因为我们之间的链接非常慢，有时可能会断开连接，如果您需要更多信息请告诉我，因为M10对他们来说太过分了。
顺便说一句，我们不会使用Citrix或VMware。
- 什么被认为是RDSH VM的控制台会话？
- 许可证服务器如何阻止每个RDSH VM有多少用户处于活动状态？
这会自动完成还是我必须手动分配号码？
谢谢。

Hi,

- Actually, the issues I have with "Hardware acceleration" is in my personnel experience using NVIDIA GPU, and with no easy way to debug the issue the only solution was to disable it.

- Branches will have their own servers, because the links between us is very slow and can sometime get disconnected, if you need more info please let me know, because M10 is too much for them.
BTW, we will not be using Citrix or VMware.

- What is considered a console session for a RDSH VM?

- How will the license server determent how many users are active per RDSH VM? will this be done automatically or do I have to manually assign a number?

Thanks.
