所有USB 3.0 SuperSpeed连接的最大同时带宽是多少？

您好月光，感谢您加入此英特尔社区。我们了解您希望获得有关所有USB 3.0 SuperSpeed连接的最大同时带宽的更多信息。
我想帮助你。为了提供准确的信息，我想知道你是否正在使用特定的系统。
另外，如果您正在开发硬件/软件，请告诉我们.Wanner G.

Hello moonlights, 

Thank you for joining this Intel Community.

I understand that you would like to get more information about the maximum simultaneous bandwidth across all USB 3.0 SuperSpeed connections. I would like to assist you with this. 

To provide accurate information, I would like to know if you are working with a specific system. Also, please let us know if you are developing hardware/software.

Wanner G. 

很高兴收到你的来信。
我的系统现在使用的是supermicro的x10drl-i主板，它使用intel c612芯片组用于u***外设。
我发现它只有单个intel u*** 3.0可扩展主机控制器，但有多个u***3端口。
所以我想知道5Gbps的带宽将在这些端口之间共享吗？
我现在很困惑是因为，我连接了2台u***3相机，每台相机将使用390MBps或3.12Gbps，因此两台相机的总数将超过5Gbps。
但令人惊讶的是，这两台摄像机可以全速运行，没有任何问题。
因此，我想知道为什么或怎么样？
谢谢。

Glad to hear from you.
 
My system is now using supermicro's x10drl-i motherboard, which it is using intel c612 chipset for u*** peripheral. I found that it is only having single intel u*** 3.0 extensible host controller, but multiple u***3 ports. So i would like to know is that the bandwidth of 5Gbps will share among these ports? 
 
I am confusing now is because, i connected 2 pcs of u***3 cameras which each one camera will uses 390MBps or 3.12Gbps, so total both cameras will over 5Gbps. But amazingly happened that those 2 cameras can run together in full speed without any problem.
 
Thus, i would like to know why or how can it be? Thanks.

您好月光，感谢您的回复。因为您的主板上有英特尔®C612芯片组，值得注意的是Supermicro等系统制造商可以改变英特尔®芯片组的功能。
即使这是您系统的一部分，我们也不知道Supermicro如何使用它来设计他们的主板。
出于这些原因，我们的建议是您可以联系Supermicro以确保您将收到有关所有USB 3.0 SuperSpeed连接的最大同时带宽的准确信息。此外，您可以在我们的资源和附件上创建一个帐户。
设计中心获取有关我们的英特尔®芯片组的具体信息，并将其与您的系统制造商的文档进行比较。资源和

Hello moonlights, 

Thank you for your response. 

Because the Intel® C612 Chipset is on your motherboard, it is worth noting that system manufactures such as Supermicro can change the features of the Intel® Chipset. Even though this is part of your system, it is unknown to us how Supermicro used it to design their motherboard. For these reasons, our recommendation is that you can contact Supermicro to make sure that you will be receiving accurate information about the maximum simultaneous bandwidth across all USB 3.0 SuperSpeed connections.

In addition, you can create an account on our Resource & Design Center to get specific information about our Intel® Chipsets and compare it with your system manufacturer's documentation.

I hope you find this information helpful.

嗨，万纳，
如果intel c612芯片组只有一个USB3.0可扩展主机控制器，那么无论接线如何，最大带宽应该只有5Gbps，对吧？
如果是这样的话，那么主板制造商无法在所有USB3端口上实现最大同时带宽，对吧？
希望再次收到你的来信，谢谢。



以下为原文

Hi Wanner,
 
If intel c612 chipset is only having 1 USB3.0 extensible host controller, then the maximum bandwidth should be only 5Gbps no matter how is the wiring, right?
 
If that's the case, then nothing motherboard maker can make it maximum simultaneous bandwidth across all USB3 ports, right?
 
Hope to hear from you again, thanks.

你好月光，在这种情况下，你要求的信息是非常具体的，它涉及由Supermicro设计的主板。
出于这些原因，最好的行动方案是联系Supermicro或我们的英特尔®资源管理器。
设计中心可以获得准确的信息。希望其他用户能够提供有关所有USB 3.0 SuperSpeed连接的最大同时带宽的更多信息.Wanner G.



以下为原文

Hello moonlights, 

In this case, the information you are requesting is very specific and it involves a motherboard designed by Supermicro. For these reasons, the best course of action would be to contact Supermicro or our Intel® Resource & Design Center to get accurate information.

Hopefully, other users will provide more information about the maximum simultaneous bandwidth across all USB 3.0 SuperSpeed connections, too.

Wanner G. 

亲爱的万纳，
感谢，并将使用supermicro检查更多细节。

Dear Wanner,
 
Noted with thanks, and will check more details with supermicro.
