你好,

使用C-NIC-10G-2-SI 10G网卡的Nutanix NX-8035-G5和NX-6035C-G5节点，支持哪些10G SFP+ LR(单模)模块?SFP+是否需要特殊的标识，例如用于思科交换机?

谢谢,
埃里克

\nthe \"use the switch MFGs\" mantra is the generally accepted ebb and flow when it comes to LR optics, mainly because we do not ship our own LR optics.
\n
\nWe do provide SR optics for customers who request it. In that situation, sometimes the client will get the Switch MFG for the switch ports, and ours for our ports, to keep both parties happy, but realistically, the \"use the switch MFGs\" still works out 99.9+% of the time.

\nwhich 10G SFP+ LR (single mode) modules are supported in Nutanix NX-8035-G5 and NX-6035C-G5 nodes with C-NIC-10G-2-SI 10G network interface cards? Do the SFP+ need special branding, as e.g. for use with Cisco switches?

LR光学吗?为什么不是SR光学?我们在数据中心不经常看到LR光学，因为大多数运行在~100米以下，因此使用更便宜的SR光学。

也就是说，我们不强制任何类型的SR或LR的兼容性矩阵。我们建议你使用任何你的交换机制造商支持(所以如果你运行cisco，使用cisco，等等)

\nThat said, we dont enforce any sort of compatibility matrix for SR or LR. We recommend you use whatever your switch manufacturer supports (so if you run cisco, use cisco, etc)","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨,乔恩,

LR，因为客户想在他们的数据中心的任何地方使用它们。这可以简化物流和更好的批量定价。

当然，客户采购了由交换机制造商支持的SFP+模块，并希望将这些模块也用于Nutanix节点。这似乎是一个有效的选择，直到在一些较老的Nutanix节点上测试可用的SFP+模块失败。遗憾的是，我没有自己做这些测试，手头既没有SFP+模块，也没有Nutanix节点。

我找到一个英特尔的网页，上面说只有英特尔SFP+模块才能在英特尔X520网卡上工作(http://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005528.html)．因此，从交换机得知的SFP+支持问题现在可能出现在服务器上。

谢谢,
埃里克

\nLR because the customer wants to use them basically everywhere in their datacenter. This allows simplified logistics and better bulk pricing.
\n
\nOf course the customer procures SFP+ modules supported by the switch manufacturer and wants to use those for the Nutanix nodes as well. That seemed to be a valid choice, until testing the available SFP+ modules in some older Nutanix node was unsuccessful. Regrettably I did not do these tests myself and have neither the SFP+ modules nor the Nutanix nodes at hand.
\n
\nI have found a web page from Intel stating that only Intel SFP+ modules work in Intel X520 NICs (http:\/\/www.intel.com\/content\/www\/us\/en\/support\/network-and-i-o\/ethernet-products\/000005528.html<\/a>). Thus it seems possible that the SFP+ support problem known from switches now emerges with servers.
\n
\nThanks,
\nErik","quoteUsername":"auerswald","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

每个拥有SFP+接口的人总是会说“只有他们自己的东西才能工作”，因为这是他们唯一能支持的，而不可能希望测试所有的东西。

当谈到LR光学时，“使用开关mfg”的咒语是普遍接受的潮起潮落，主要是因为我们没有发布我们自己的LR光学。

我们为有要求的客户提供SR光学。在这种情况下，有时客户会为交换机端口得到Switch MFG，为我们的端口得到我们的MFG，以使双方都满意，但实际上，“使用交换机MFG”仍然在99.9+%的时间工作。


无论如何，对于您的特殊情况，需要通过支持票来推动补救，这样我们就可以帮助深入了解出了什么问题。
