Supermicro Ultra SYS-120U-TNR Review: Testing Dual 10nm Ice Lake Xeon in 1Uby Dr. Ian Cutress on July 22, 2021 9:00 AM EST
With the launch of Intel’s Ice Lake Xeon Scalable platform comes a new socket and a range of features that vendors like Supermicro have to design for. The server and enterprise market is so vast that every design can come in a range of configurations and settings, however one of the key elements is managing compute density with memory and accelerator support. The SYS-120U-TNR we are testing today is a dense system with lots of trimmings all within a 1U, to which Supermicro is aiming at virtualization workloads, HPC, Cloud, Software Defined Storage, and 5G. This system can be equipped with upwards of 80 cores, 12 TB of DRAM, and four PCIe 4.0 accelerators, defining a high-end solution from Supermicro.
Servers: General Purpose or Hyper Focused?
Due to the way the server and enterprise market is both expansive and optimized, vendors like Supermicro have to decide how to partition their server and enterprise offerings. Smaller vendors might choose to target one particular customer, or go for a general purpose design, whereas the larger vendors can have a wide portfolio of systems for different verticals. Supermicro falls into this latter category, designing targeted systems with large customers, but also enabling ‘standard’ systems that can do a bit of everything but still offer good total cost of ownership (TCO) over the lifetime of the system.
Server size compared to a standard 2.5-inch SATA SSD
When considering a ‘standard’ enterprise system, in the past we have typically observed a dual socket design in a 2U (3.5-inch, 8.9cm height) chassis, which allows for a sufficient cooling design along with a number of add-in accelerators such as GPUs or enhanced networking, or space on the front panel for storage or additional cooling. The system we’re testing today, the SYS-120U-TNR, certainly fields this ‘standard’ definition, although Supermicro does the additional step of optimizing for density by cramming everything into a 1U chassis.
With only 1.75-inches (4.4cm) vertical clearance on offer, cooling becomes a priority, which means substantial enough heatsinks and fast moving airflow backed by 8 powerful 56mm fans, which are running at up to 30k RPM with PWM control. The SYS-120U-TNR we’re testing has support for 2 Ice Lake Xeon processors at up to 40 cores and 270 W each, as well as additional add-in accelerators (one dual slot full height + two single slot full height), and comes equipped with dual 1200W Titanium or dual 800W Titanium power supplies, indicating that it is suited up should a customer want to fill it with plenty of hardware. You can see in the image above and on the right of the image below, Supermicro uses plastic baffles to ensure that airflow through the heatsink and memory is as laminar as possible.
LGA-4189 Socket with 1U Heatsink and 16 DDR4 slots
Even with the 1U form factor, Supermicro has enabled full memory support for Ice Lake Xeon, allowing both processors sixteen DDR4-3200 memory slots, capable of supporting a total of 12 TB of memory with Intel’s Optane DCPMM 200-series.
At the front are 12 2.5-inch SATA/NVMe PCIe 4.0 x4 hot swappable drive bays, with six apiece coming from each processor. If we start looking into where all the PCIe lanes from each processor go, it gets a bit confusing very quickly:
By default the system comes without network connectivity, only with a BMC connection for admin control. Network options requires an Ultra add-in riser card for dual 10GBase-T (X710-AT2), or dual 10GBase-T plus dual 10GbE SFP+ (X710-TM4). With the PCIe connectors, any other networking option might be configured, but Supermicro also lists the complete no-NIC option for air-gapped systems. The system also has three USB 3.0 ports (2 rear, 1 front), a rear VGA output, a rear COM port, and two SuperDOM ports internally.
Admin control comes from the Aspeed AST2600 which supports IPMI v2.0, Redfish API, Intel Node Manager, Supermicro’s Update Manager, and Supermicro’s SuperDoctor 5 monitoring interface.

domih - Thursday, July 22, 2021 - linkForgot to mention: the testing/benchmark is done with the software that will run on the systems once acquired, not synthetic/generic benchmarks which you might use at the beginning to validate the systems. 90+% of the testing is done with production / apps and load scripts to feed them.
mode_13h - Friday, July 23, 2021 - linkThanks.
> you may select not the fastest system
Right, so it sounds like a lot for 70% of sales to hinge on performance, much less specifically AVX-512.
I guess where my skepticism comes from is in cloud scenarios where there's not just a single app the customer intends to run. In such cases, I don't know how you can say that AVX-512 made the deal, unless they use it as a generic answer to reservations the customer might raise about performance.
Also, I just can't see the case for many customers to even care about vector arithmetic. If you're running a web server, CI (Continuous Integration), or many databases, it's integer performance you're likely to care about. 70% of the workloads running on cloud & enterprise servers aren't even ones that benefit from AVX-512!
jospoortvliet - Friday, July 23, 2021 - linkWell, I'd say it is possible 70% of their sales wins relies on this one AVX-512 feature - but if you are right and it is only interesting for a minority of customers, that simply means they are not selling a lot... And indeed, if this argument goes away with AMD's next gen, that's even worse news.
mode_13h - Saturday, July 24, 2021 - link> that simply means they are not selling a lot...
All of their BIG server processors since 2017 support AVX-512. And while the Datacenter Group's revenues are down, they're still the second-biggest profits among Intel's business units.
Spunjji - Monday, July 26, 2021 - link@mode_13h - that's a very good point. Maybe it's one of those things where the buyer would have selected Intel anyway for ancillary reasons. but are offering AVX-512 as a rationalisation when given a limited range of options for providing feedback (which would imply it's the thing the sales guys are selling hardest).
Spunjji - Monday, July 26, 2021 - linkThat really does depend on the size / expertise of the customer / reseller involved.
domih - Monday, July 26, 2021 - linkThat too!
Oxford Guy - Sunday, July 25, 2021 - linkAVX-1024!
mode_13h - Sunday, July 25, 2021 - linkSapphire Rapids has AMX, which is a little like AVX-8192. I think it'll be a big win for a few very specific cases, but less generally useful than AVX-512.
Spunjji - Monday, July 26, 2021 - linkNiches within niches, but look how deep this niche goes!
