Advantech SKY-8101L Overview
The Advantech SKY-8101L is a series of 1U servers that leverage a single Intel Xeon Scalable processor. The family uses a 27.5" short-depth design, making them ideal for situations where density is critical. Storage configurations vary across the models with up to 8x 2.5" hot-swappable HDD/SSD drives and optional 2x 2.5" NVMe SSDs, or 4x 3.5" hot-swappable HDD drives. The servers also have a single M.2 2280 SATA slot for boot SSD. Additionally the servers support 6x DIMM sockets and two FHFL PCIe x8 Gen3 slots.
While Advantech isn't necessarily a household name in the enterprise, they have done well for themselves in specific verticals because of the tuning they put into the servers. The SKY-8101L for instance is heavily slanted for edge computing use cases. They're commonly found in use cases like telcos and as part of content delivery networks that are able to run their own applications on these unique server configurations. Specifically, the SKY-8101L does well when high density PCIe card payloads and maximum I/O connectivity is required.
The systems are also designed to account for the suboptimal operating conditions at the edge. The SKY-8101L is designed to withstand environmental conditions like shock, vibration and higher operating temperature. These types of conditions would be seen in very remote offices (oil/gas exploration, military), edge telco buildings and other areas where traditional environmental controls would not be available. The systems have redundant power supplies, can withstand fan failures, and have redundant firmware images with failsafe upgrades.

Build and Design
All three models have the same overall chassis. The unit in our lab, the SKY-8101L3, has four 3.5” bays running across the bottom. Along the top is ventilation along with two USB 3.0 ports, a console port, an ID button, and power button. The other two models have 2.5” ports stacked one on top of the other across resulting in ten bays on the L1 and 8 bays on the L2. Both have a power button, ID button, one USB 3.0 port, and one micro-USB console port. The L2 has four more networking ports in the front.
The back of the server looks that same on all models. The left side has the two PSUs followed by a DisplayPort, two GbE LAN RJ45 ports, two 10GE SFP+ ports, and two USB 3.0 ports.
The server is easy to pop open and take a look at what is under the hood. In the center of the device, one can clearly see the CPU surrounded by the RAM. The front of the Device has the storage and fans. On one side of the CPU are the PSUs and the other is open for PCIe additions such as GPUs.
While the specific configuration of the Advantech SKY-8101L server in our lab wasn't designed for high-performance benchmarking, we do enjoy taking a look at novel server designs when we can. The use cases Advantech is after here are much different than traditional enterprise workloads and we think it important to get a little outside of the norm form time to time. That said, while most use cases include information analysis and streaming at the edge, a SKY-8101L configured with flash could make for a good vSAN node at the edge. There are certain management benefits that come along with a solution like that, while keeping the solution cost-optimized with a single CPU. The Advantech SKY-8101L family fills a gap overlooked by traditional server vendors and serves an increasingly vital role in the edge computing category.
