Xeon D-2100 Motherboards Appearing

ASRock Rack D2100D8UM

Jumping the gun just a little, we were sent a link to ASRock Rack who has already put some of its Xeon D-2100 products up on the website. Specifically, the D2100D8UM shows a motherboard with a fixed embedded socket, eight memory slots, two PCIe slots, a pair of SFF-8643 breakout ports, and an integrated IPMI with a dedicated network port. In order to take advantage of the integrated 10 GbE ports, customers will have to use a mezzanine card with the appropriate PHY.

We’re not entirely sure how long ASRock Rack has been preparing for this platform, although this looks like one of its more integrated platforms, probably designed for a specific customer in mind. The webpage states in the main headline that it supports up to 512 GB of DDR4, but in the specification table it says it only supports 128 GB of DDR4. Both segments however do clarify RDIMM and LRDIMM support, which is a positive.

The PCIe slots are physically an x16 slot and an x8 slot, however there are only 16 lanes between the two and they act in a switching capacity, for x16/x0 or x8/x8 operation. For a system that has access to 32 PCIe lanes, looking through the specification sheet it is not overtly obvious where the other 16 from the SoC have gone. It would seem that in the interest of cost (or the specific customer), they are simply not used.

Elsewhere on the board is almost a full set of SATA ports. Three SATA ports are standard SATA ports, 1 is a SATA DOM, and eight SATA ports come from the two SFF-8643 breakout connectors. This totals twelve ports, although the platform supports 14. Similarly, there is a single USB 3.0 port, a single USB 2.0 port, and one header each for USB 2.0 and USB 3.0. On the rear panel there is an Ethernet port for the integrated management chip, an Aspeed AST2500, along with a VGA header for management as well. Other networking and USB ports have to be added in by the customer.  There are also five fan headers.

ASRock Rack does not list the exact processors that it will put into this motherboard, stating that it supports up to 110W, which would cover the full list. It is likely that interested parties will have to inquire as to exact pricing depending on the D-2100 series needed.

Many thanks to SH SOTN for the link.

    I'm not sure what/who the target market is for the D-2191. The core count says "high end", but the TDP, base frequency, DDR frequency, and unique lack of integrated Ethernet is weird. It feels more like an "embedded Xeon-W" than a "Xeon-D". Reply

    Here's what one article had to say:

    "Looking back to the previous generation, Facebook utilized Mellanox multi-host adapters along with a custom version of the original Xeon D to lower networking costs and improve performance. We suspect that Intel is keenly aware of this and that is a part of the reason for that de-feature move."

    That explains it. And after a few quick searches, I found Open Compute Project PDFs that explain the setup where integrated networking would be pointless. Thanks! Reply

    Always read the fine print:
    Benchmark results were obtained prior to implementation of recent software patches and firmware updates intended to address exploits referred to as "Spectre" and "Meltdown". Implementation of these updates may make these results inapplicable to your device or system.

    While I can see uses for these, until I see how they run with the patches in place this announcement is garbage.

    So, you pay $2400 for Meltdown and Spectre? Reply

    You`ve been paying for it for 20 years now without a single peep. You'll buy your Mossad processor and you will like it, goy. Reply

    It's strange, I had to change to my AMD system to type "Palestinian genocide/Apartheid" it wouldn't work on my i5 box. Reply

    My i5 box always tries to inject something about toxic masculinity and opressive whiteness into every text I type in Word! Reply

    Showcasing benchmark results without applying critical patches seems wrong on every level. Reply

    Just subtract 30% and you've got it. Reply
