Supermicro AS-1024US-TRT Block Diagram
Supermicro’s block diagram is basically done at two levels. The first is at the level of the Supermicro H12DSU-iN motherboard that is shared with this server along with other Supermicro designs.
The second is at the system level which has a fairly high-level diagram. Here we can see a few important points:
First, we can see that we need both CPUs installed to provide I/O connectivity to the full server and slots. Second, we can see that we have a full socket-to-socket link between the two processors. In a 1U system, having the 3x XGMI2 link configuration making 16x PCIe lanes available is less desirable since there is physically a limit to how much I/O one can fit into a 1U server. Dell’s motherboard in this 1U dual EPYC class, for example, has that flexibility, but in its 1U form factor, it is a cost adder without much if any practical benefit in the system.
Supermicro AS-1024US-TRT Management
These days, out-of-band management is a standard feature on servers. Supermicro offers an industry-standard solution for traditional management, including a WebGUI. This is based on the ASPEED AST2500 solution, a leader in the BMC field. The company is also supporting the Redfish management standard. Something that we wanted to highlight is that the password has changed.
Our system had the unique password solution built-in. This is mandatory on new servers due to legal requirements. For a quick overview of why Supermicro and the rest of the industry are moving to unique BMC passwords, you can see Why Your Favorite Default Passwords Are Changing and the accompanying video:
On this server, we see similar features as we would across the Supermicro A2/X11/H12 ranges. That means whether you are using an embedded Intel motherboard or a 4U Intel Xeon or AMD EPYC storage server, you will have a similar look and feel to the management experience.
In the latest generation of Supermicro IPMI is an HTML5 iKVM. One no longer needs to use a Java console to get remote KVM access to their server.
Currently, Supermicro allows users to utilize Serial-over-LAN, Java or HTML5 consoles from before a system is turned on, all the way into the OS. Other vendors such as HPE, Dell EMC, and Lenovo charge an additional license upgrade for this capability (among others with their higher license levels.) That is an extremely popular feature. One can also perform BIOS updates using the Web GUI and even do simple tasks such as power cycling the server.
This pricing differential for a serviceable iKVM functionality is a big deal in this segment. Adding a $200 license to a server can add 10% or more in the embedded platform costs. Supermicro’s iKVM feature is extremely popular due to its inclusion with the server.
Next, we are going to discuss performance.
