One of the most awesome things about AMD EPYC Bergamo is the core count. We have up to 128 Zen 4c cores / 256 threads in a single socket. That means the Supermicro AS-2015HS-TNR that we are reviewing today can consolidate between two and four dual-socket 2020-era Intel Xeon servers into a single-socket 2U server. In our review, we are going to look at the server that makes this possible.
Supermicro AS-2015HS-TNR External Hardware Overview
On the front of the server, we get twelve 3.5″ bays with orange tabs.
These orange tabs mean that we have an option for either adding 3.5″ hard drives or 2.5″ SSDs. We will quickly note that only the 3.5″ drives are tool-less for installation.
Here is a look at a Micron NVMe SSD in the larger 3.5″ drive tray.
Something that is different with this generation compared to previous generations is the backplane. Looking at the storage backplane we can see not only the drive connectors but a PCB where much of it has been removed for airflow purposes. If you look between the fan blades, you can actually see all the way through to the rear of the chassis fairly easily. New servers focus on airflow, and this is a good example.
Moving to the rear, we get a Supermicro ultra configuration. The new servers have two power supplies. There are two USB ports and a VGA port for local management. Then there is an out-of-band management NIC for IPMI/Redfish access. Aside from that, the rest is dedicated to airflow and expansion.
Here is one of the two 1.2kW 80Plus Titanium power supplies in the system.
Showing the airflow a bit more in the server, here is a look down the power supply slots. We can clearly see the midplane fans and PSU fans are meant to keep airflow over the relatively lower-power DDR5 DIMM slots.
Since there is no onboard networking, we have the Supermicro AOC-S100G-b2C network card. This is a Broadcom BCM57508-based 100GbE network adapter. Supermicro has other 100GbE adapters including the Intel-based AOC-S100GC-i2C 100GbE as well as other options.
Both the riser above the power supplies and the one in the middle of the chassis are very similar. They are also cabled risers so they no longer slot into the motherboard.
The final four-slot riser has the same top two slots, but then the bottom part of the riser is slotted into the motherboard on a separate riser PCB. Our example has a PCIe Gen5 x16 double-width slot available for GPUs, FPGAs, or other accelerators, but there are other options.
Next, let us get inside the system to see how that looks.
