I'm at my wits end with this, Citrix is stumped, Dell is stumped, and with the supply chain issues the way they are we can't just yank these out in favor of X550s. The problem is we have a group of Dell R740s with X710 dual-port NICs and the performance is, in a word, awful. Like 5-6 megabit upload and 250 megabit download awful. However, identical server hardware with any other card, be it a Broadcom or an Intel X550T, no issues. We can get line rate all day long. The latest attempt was swapping the X710 for a newer X710-T2L-t, which performed maybe 5-10 percent better. We've tried three different driver revisions, firmware, BIOS, all the available Hypervisor updates, it still performs the same.
The servers in question have X550s on the motherboard mezzanine card which perform fine, and a single dual-port X710 in the PCIe riser. The X710 is set up with an LACP pair trunked with three VLANs tagged across it. In this pool we also have servers with X550s on the PCIe cards, and Broadcoms. All those with an identical configuration perform without issue, it's only the X710s that show this problem.

Otherwise we're looking at July for availability of X550s on a PCIe card from Dell. -Matt Weiner _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel Ethernet, visit https://forums.intel.com/s/topic/0TO0P00000018NbWAI/intel-ethernet
