Supermicro AS-E301-9D-8CN4 Power Consumption
We used our pair of Extech TrueRMS Power Analyzer 380803 units to take measurements at different points of the Supermicro AS-E301-9D-8CN4 use on 120V power in the embedded lab. Embedded platforms tend to spend more time at the edge in offices rather than in higher power data centers, hence why we do our testing at a lower voltage. Here are the figures:
- Power off BMC only: 4.7W
- OS Idle: 33.7W
- 100% Load: 71.8W
- Maximum Observed: 97.4W
With three fans, the Supermicro AS-E301-9D-8CN4 uses more power than some other configurations. If one has less storage and never plans on installing an add-in card a fan can be removed with impact to power consumption.
Still, the Supermicro AS-E301-9D-8CN4 performs well and at a lower power level than many of the Intel Xeon D-2100 performance competitive solutions. In the embedded market, low power is key. It is not quite at the Intel Atom power consumption levels but it is competitive with the Intel Xeon D-1500 and newer Xeon D-1600 series.
We wanted to take a moment here and discuss noise. The solution is too loud to have sitting on one’s desktop. On one hand, this is a high-performance CPU and a lot of components in a small box. On the other hand, using a 1.5U design, based on a 1U design, means that the Supermicro AS-E301-9D-8CN4 is still using 40mm 1U fans for cooling, not larger quieter units.
STH Server Spider: Supermicro AS-E301-9D-8CN4
In the second half of 2018, we introduced the STH Server Spider as a quick reference to where a server system’s aptitude lies. Our goal is to start giving a quick visual depiction of the types of parameters that a server is targeted at.
The Supermicro AS-E301-9D-8CN4 is not meant to be the densest platform. Instead, it is intended to be compact in size. To this end, it achieves its goal.
Overall, we think that the Supermicro AS-E301-9D-8CN4 makes a great AMD EPYC 3000 test platform. If you have a small cluster setup for testing based on the Supermicro CSE-E300 chassis, adding a Supermicro AS-E301-9D-8CN4 to the mix will be easy. For embedded appliance makers, we think this is a great option, but wish that Supermicro offered more SKUs. The design means that we think that this can be used as a reference with other M11SDV and even Intel-based platforms.
At under $1000 street price, we think this is a solid solution, but wish that Supermicro had a SKU variant that was a few dollars more but included everything (e.g. brackets, cables, and adapters) to make a fully functional system. We can see Supermicro’s channel partners and end users getting the systems and then wanting the optional features to fully configure the servers. A $1025 street price that had everything but without having to look-up individual pieces would be excellent and relatively easy to accomplish.
Another small point is that there are entirely too many screws in this design. It may be by a margin of four, but it is still too many. We like that Supermicro went to tool-less 7mm SSD installation, that is great. At the same time, we hope that innovation to remove screws extends past SSD installation to make these boxes more serviceable. Replacing a SATA DOM in the field will take at least eight screws to remove, then re-install. At the same time, we like features like the locking DC power supply.
If you are looking for a desktop/ appliance version of an AMD EPYC 3000 series server that is not tied to a rackmount, we like the Supermicro AS-E301-9D-8CN4. Adding additional storage over CSE-300 based offerings is a welcome design direction in this space.
