Upgrade Supermicro Xeon D-1540/1541 from BIOS 1.0b/1.0c to 1.1 for identical features, including SR-IOV for 10GbE!
I have good news. I've been testing the latest BIOS 1.1 from Supermicro for the SYS-5028D-TN4T system with the X10SDV-TLN4F motherboard, which was quietly released today for download. Why is this good news?
Well, the original SYS-5028D-TN4T buyers with the Xeon D-1540 onboard has the Rev. 1.02 motherboard that had 1.0a BIOS originally, with the latest BIOS being 1.0b, ever since my September 2015 article that detailed the BIOS upgrade procedure.
Then along came the Xeon D-1541, a slight speed boost (<5%) that replaced the Xeon D-1540 in late February 2016. It has the Rev. 2.00 motherboard that came already flashed to BIOS 1.0c, which was never offered for download anywhere. It was a stop-gap. BIOS 1.0b and 1.0c differed quite a bit in various areas, and that was kind of annoying, especially when trying to document things for folks who bought a Supermicro bundle at Wiredzone.
Today, Supermicro resolved all that, making BIOS 1.1 available for any Xeon D-154x owner, right here:
BIOS 1.1 is what's listed on the VMware HCL for this system, arguably the very first server suited for home lab use ever listed there, and certainly the only Xeon D-1500! This listing is pictured at right.
SR-IOV is back! Yes, it went away on 1.0b, but with 1.1, both the Xeon D-1540 and Xeon D-1541's Intel X552 10GbE interfaces are SR-IOV capable. My tests were basic and quick, but everything seemed to work just fine. How do you enable SR-IOV? I covered that here:
First Look - SR-IOV support in Intel Xeon D-1541
Your current BMC IP address is displayed seconds after you power up, nice touch! (pictured below)
- All menus and submenus are identical, whether you have a Xeon D-1540 and Xeon D-1541 (only the boot screen seems to differ in a non-functionally significant way, seen here in the video below)
For me personally, I won't be using SR-IOV fulltime, with the drawbacks (can't do vMotion of that VM, or make any changes without shutting it down) outweighing the benefits (scalability), but that's just me. But for many looking to eek that every last bit of performance out of the Intel X552 10GbE, it's an important feature, especially for production and datacenter use. It's good that finally, Supermicro has apparently been able to get SR-IOV working, delivering on that promise that Intel had made during the Xeon D-1500 announcements one year ago.
I don't have video of implementing SR-IOV on VMware just yet, but for now, I do have a screenshot for you, below.
My particular 1.0c seemed to have CSM (Compatibility Support Mode) off, by default. While this could squeeze a slight performance boost, this posed a problem for upgrading. I was using USB boot media, as you'll see in the below video. Once I turned CSM ON, I got past that little bump in the road, and the rest of the upgrade was simple.
It's a nice sign of maturity that BIOS 1.1 has been released, no more minor release letters, and a nice new display of the BMC IP address right on the boot screen. This is extremely handy for that first boot experience, as you now easily know what IP to connect to, no need to dig through the BIOS for IPMI settings. By the way, no new IPMI yet for Xeon D-1540, still at 2.14 for now, and Xeon D-1541 at 3.26.
Note that all Wiredzone SuperServer Bundles are now Xeon D-1541 CPUs, and will now be shipped with BIOS 1.1 already flashed for you.
While Supermicro is not big on release notes, at least you have this article and video!

I mentioned that Xeon D-1541 arrived with IPMI 3.26. Good news, Xeon D-1540 owners can now download IPMI 3.26 from Supermicro:
Proceed at your own risk, and work with Supermicro 24x7 should you encounter any issues. I have not tested this upgrade procedure yet, nor have I tested this 3.26 on the Xeon D-1540 system. It came preloaded on the Xeon D-1541 that I have heavily tested.
