In one of the more ambitious projects STH has undertaken, we have a Huawei TaiShan server to show you. What makes this server more interesting than being banned in the US, is that the CPUs it uses are Arm server CPUs from Huawei/ HiSilicon. Specifically, this is a Huawei/ HiSilicon Kunpeng 920 server that was one of the first Armv8 server CPUs with up to 64 cores and PCIe Gen4 support. In terms of project status, this server has been very finicky, something we covered in the recent Solidigm D7-P5520 7.68TB PCIe Gen4 NVMe SSD Review on x86 Arm and Power9 piece. So instead of a review at this point, we are going to approach this more to just document what we found and discuss what makes this banned server unique. As we went through the hardware configuration, it was clear that this server was very different, and there was a ton to cover just looking at the hardware.
Huawei TaiShan 200 2280 Server Overview
We are going to split our hardware overview into two sections. We will have an external and internal overview. On the internal overview, we are going to deep-dive with more photos than normal on some of the really interesting non-CPU components. There will also be a second piece dedicated to the Kunpeng 920. If you prefer to listen and see more shots via video, we have a video for this:
As always, we suggest opening it in its own browser, tab, or app for the best viewing experience. There are a few angles in the video we do not have pictures of just due to the nature of video.
Huawei TaiShan 200 2280 External Server Overview
Starting with the front of the server, this is a 25-bay 2.5″ design but we only had 24 drive trays. That is a fairly standard configuration for 2U servers, at least until we get into the EDSFF era.
In this server, eight slots are NVMe while the other slots are SATA/ SAS.
Something that was surprising is that the drive trays were not tool-less. They still require screws. Huawei also uses drive blanks like Dell EMC, HPE, and Lenovo rather than just providing drive trays like Supermicro, Inspur, QCT, and others.
While this is a TaiShan 200 2280, this is the label for the part with K22R-02.
On the left side, we get the Huawei logo, power, and status LEDs/ LCD.
On the right side, we get a VGA port and two USB 3.0 ports. Most servers we review have at most a single front USB port, so that is a little bit different.
Moving to the rear, things start to get a bit more exciting. One can see that there are eight full-height PCIe slots, but only one can be used for a card.
Primary networking is provided via two OCP NIC 3.0 slots. We will deep-dive into this quad port 1GbE solution, but let us just say it is one of the most interesting solutions out there.
The main I/O block has management, RJ45 serial, VGA, and two USB ports. This is a standard stack except we rarely see the RJ45 form factor serial ports in servers. Those are more common in switches and firewalls. That section is connected to a PCB with a chip we cannot find information on via Google, and we will go into that in our internal deep-dive.
The other OCP NIC 3.0 slot is to the right of the I/O block.
In Slot 8 we get a quad 25GbE port HNS card.
One of the two power supplies got damaged during shipping. This one has many ratings and certifications, including the 80Plus Platinum certification. It is also a 200V+ power supply so it is not meant for lower power 110-120V North American racks.
As exciting as that is, the more exciting aspect is really what we see inside the server. From the outside, this is fairly standard. Once we get inside, things get interesting. Let us move on to that.
