ASUS RS500A-E9-RS4-U ASMB9 Management

With this generation of the ASUS out-of-band management implementation, the company is using standard MegaRAC firmware. That brings a number of new features including a responsive web layout.

One of the other big features is the ability to use a HTML5 iKVM. We had a number of ASUS servers in the lab previously where the Java iKVM client would constantly require firmware updates to function due to Java security certificates. This is a big win for the company.

At STH, we recently posted a video tour of the management interface. You can see the tour here:

Overall, this is a more modern experience. At the same time, ASUS is focused on providing more of the standard MegaRAC firmware rather than adding an enormous set of proprietary features. Many customers want exactly this. Others like the features that Dell EMC, HPE, Lenovo, and others provide to their customers.

Next, we are going to look at the test configuration before moving on to our performance testing.

ASUS RS500A-E9-RS4-U Topology

One area that we are keenly aware of today, and will be increasingly so with future multi-chip packages, is system topology.

With a single socket, the AMD EPYC platform has everything connected to a single CPU. At the same time, we can see that ASUS is using I/O from different dies for its onboard devices. That generally increases socket-to-socket communication needs.

ASUS RS500A-E9-RS4-U Test Configuration

The ASUS RS500A-E9-RS4-U we tested in a number of configurations. Here is the set of hardware we used:

  • Server: ASUS RS500A-E9-RS4-U
  • CPUs: AMD EPYC 7251, EPYC 7281, EPYC 7301, EPYC 7351P, EPYC 7401P, EPYC 7451, EPYC 7501, EPYC 7551P, EPYC 7601
  • Memory: 8x 16GB Micron DDR4-2666
  • SSDs: 2x Samsung 960GB SATA and 2x 1.92TB NVMe U.2
  • NICs: Mellanox 10GbE OCP, Mellanox ConnectX-5 100GbE

We also installed an AMD EPYC 7371, but we did not see it on the HCL when we started testing. It worked and the topology map above was actually using that CPU.

Next, we are going to look at CPU performance of the ASUS RS500A-E9-RS4-U.
