当今数据中心用的PCI Express最强大的一个功能是I/O虚拟化。I/O虚拟化让虚拟机直接访问I/O硬件设备，提高了企业级服务器的性能。单根I/O虚拟化(SR-IOV)技术规范拉动了市场

我在我的PC中使用X710进行自定义应用程序。我正在使用SR-IOV功能。我已为每个VF分配了MAC地址。有没有办法在VF端口启用MAC学习？我的应用程序将使用生成的mac地址与对等方进行通信

亲爱的大家，我目前正在开发一个Vivado 2013.4项目，我需要利用物理和虚拟功能以及SR-IOV。我作为一个例子研究了在Virtex-7（VC709）板上实现的Xapp1177应用笔记。不幸

GPU虚拟化在哪里发生？它是否出现在GRID卡中，然后将vGPU呈现给管理程序然后呈现给客户？或者，GPU的虚拟化和调度是否真的发生在管理程序上安装的GRID管理器软件？是否使用了SR-IOV？我

我将以我不代表公司实体这一事实为导向，这意味着我没有办法购买GRID或特斯拉卡或专门用于此目的的许可。这纯粹是为了教育，概念证明和在家庭实验室环境中进行测试。正如主题建议的那样，我只是在寻找一个支持Server 2016中的离散设备分配（DDA）的非GRID非Tesla GPU列表，这样我就可以通过GPU（或者如果卡支持的话，可以通过vGPU）到Hyper -V VM。我的目标是找到一些带有详尽列表的数据表了解是否可以知道哪些卡支持DDA了解哪些卡（在GRID和特斯拉等高端卡之外）支持vGPU检查从其他人那里得到的第一手资料，这些人已完成了这些工作，获得了经验教训等我似乎有些报道表明有可能在VM中使用消费级卡（例如：GeForce）。然而，这些过程没有很好的记录，解释似乎真的很复杂，所以我不想浪费周期来跳过一堆箍。另外，我不想定期主持人BSOD，因为我正在做超级hackish的事情。我在线阅读了一些建议Quardo卡（例如：Quadro NVS，Quadro FX等）应该支持DDA /传递的东西。然而，我找不到任何文献来支持这些说法，我遇到的所有例子都是K1，Teslas等。因为我没有办法烧掉各种模型（例如：FX 3800，NVS 420， 600等）试用和试用错误，我正在向社区寻求指导。以上来自于谷歌翻译以下为原文I'm going to lead off with the fact that I do not represent a corporate entity which means I don't have the means to purchase GRID or Tesla cards or licensing specifically for this purpose.This is purely for educational, proof of concept & testing purposes in a home lab environment.As the topic suggests, I'm just looking for a list of non-GRID non-Tesla GPUs that support Discrete Device Assignment (DDA) in Server 2016 so I can pass through GPU's (or vGPU's if the card supports it) to a Hyper-V VM.My objective is tolocate some sort of datasheet with an exhaustive listunderstand whether or not it's possible to know which cards do support DDAunderstand which cards (outside of high-end cards like GRID and Tesla) support vGPU'scheck for any get firsthand accounts from others who have done this complete with gotcha's, lessons learned etcI've seem some reports that suggest it may be possible to get consumer grade cards (e.g.: GeForce) working in VM's.However, the processes are not well documented and the explanations seemed really convoluted, so I don't want to waste cycles jumping through a bunch of hoops.Plus I don't want the host BSOD'ing periodically either because I'm doing something super hackish.I've read some things online that suggest any Quardo card (e.g.: Quadro NVS, Quadro FX etc.) should support DDA/pass through.However I can't find any literature to support those claims, and all the examples I've come across are K1's, Teslas etc.Since I don't have the means to burn through various models (e.g.: FX 3800, NVS 420, 600 etc) in trial & error, I'm reaching out to the community for guidance.

PCIe真的在同以太网竞争并能胜出吗？
