With the increase in the volume of server operations, especially servers based on graphic accelerators and the introduction of powerful AMD EPYC series processors, users can access a high computational and operational volume by having only one socket in the server.

In this review, we intend to accompany you with one of the best GPU servers based on AMD EPYC processors. ASUS ESC4000A-E10 Server With support for the latest generation of AMD server-specific processors, it is possible to use eight single-slot graphics accelerators or four dual-slot graphics accelerators in 2U space.

Overview of ASUS ESC4000A-E10 server hardware

At first glance, this server has 2 units, the front part of which is almost all dedicated to storage drives. There are also four USB 3 Type-A ports, server status LED lights and a POWER button. There is also an LCD display to show POST operations to the system administrator.

ASUS ESC4000A-E10 Server Management

This server uses the ASPEED AST2500 BMC for internal management, which executes the MegaRAC SP-X commands. Asus calls the solution ASMB9-iKVM, which includes IPMI, WebGUI, and Redfish management for the platform.

ASUS ESC4000A-E10 server

This solution has a number of specific features, some of which we will discuss. Asus, for example, allows the system administrator to update the system BIOS through the standard web GUI interface. Supermicro servers require the purchase of a separate module for this.

The most interesting part of this block diagram is the ease of connectivity that Asus design engineers have achieved with just one processor socket, drastically reducing costs and using an optimal topology.

Performance of ASUS ESC4000A-E10

Old Linux-Bench scripts were used to measure the performance of this server, in which we used an updated version of these scripts, namely Linux-Bench2. Some of our benchmarks may have been running for days at a time so that the benchmarks were the same and standard.

Python Linux 4.4.2 Kernel Compile Benchmark

In recent years, this benchmark is one of the most reputable benchmarks for measuring the power of servers. Its operation is simple, from the Linux 4.4.2 kernel with standard configuration, we tested several processors from the AMD EPYC family in this server:

ESC4000A-E10 GPU

In order to validate the system and standardize it with the type of GPU used in this server and to make its performance similar to that of 4-unit servers with 8 to 10 graphical layouts, we used four NVIDIA Quadro RTX 6000 cards with Passive cooling.

ASUS ESC4000A-E10 server

The PCIe switch was not used in the system. As a result, we used the P2P transfer rate, which is AMD EPYC IO Die’s excellent topology for navigating GPU paths. Although the result will be different when installing NVLink on each pod, we examined the card server separately.

ASUS ESC4000A-E10 server

On GPU-based servers, the BIOS settings are very effective in improving the overall performance of the system, which can be changed using the Web interface in IPMI, which you can see the following results:
