SR-IOV works with VMware ESXi 6 and Xeon D-1540/1541, but Supermicro implies it's only supported with 1541

  • Just a quick update about SR-IOV support today. On Sunday, May 8th, Supermicro quietly made some updates to the Supermicro SuperServer SYS-5028D-TN4T Product Page, specifically, the Key Features section:

    Key Features

    • Space-efficient, compact design
    • Network Security Appliance
    • Cloud and Virtualization
    • High Performance NAS Servers
    • Business Critical Applications
    • Small and Medium Business
    SR-IOV supported (for Xeon D-1541)

    Admittedly, this update isn't likely to settle those longstanding questions about SR-IOV support, but it may help folks to know what (little) Supermicro has to say about this. Also note that I never did get SR-IOV to work on the two 1GbE Intel I-350 ports, but I didn't try that hard either.

    If you're really in need of using SR-IOV for your heavy workload and/or production environment, you'll instead really want to check out Patrick's definitive article about this:

    The Supermicro SYS-5028D-TN4T system uses the X10SDV-TLN4F motherboard, so it's worth noting that the Supermicro X10SDV-TLN4F Motherboard Product Page hasn't yet been updated to mention SR-IOV yet. Likely just something they overlooked. I've reached out to Supermicro.

    Finally, here's the original press release, which clearly mentioned SR-IOV for this very same motherboard:

    Product Specifications

    I don't have near-term plans to revisit this topic, as I'd rather use those two precious 10GbE interfaces for a variety of roles such as a vMotion and/or vSAN, rather than pinning them to some VMs. Using SR-IOV would also preclude me from using the fun and useful home lab stuff I regularly do with those VMs, such as snapshots and vMotion.
