ASUS ESC4000A-E12 AMD EPYC Zen 4 Barebones Server (2U)


In stock


AMD EPYC™ 9004 single-processor 2U GPU server that supports four dual-slot GPUs, liquid cooling solution, up to 12 DIMM, 8 PCIe 5.0 slots, six NVMe, OCP 3.0 and ASMB11-iKVM.

Four Dual-Slot GPU Compute in 2U

ESC4000A-E12 is an AMD EPYC™ 9004 single-socket server built for the demands of enterprise AI infrastructure to deliver unprecedented performance with industry-leading GPUs, faster GPU interconnect and higher-bandwidth fabric, and supports up to four dual-slot active or passive GPUs scalable configuration with a choice of NVIDIA NVLink® Bridge or AMD Infinity Fabric™ Link to enable scaling of performance with increased bandwidth — ready to match your AI and HPC workloads.

Faster Storage, Graphics and Networking Capabilities

PCI Express® (PCIe®) 5.0 delivers 32 GT/s bandwidth, which is twice the speed of PCIe 4.0, and offers lower power consumption, better lane scalability and backwards compatibility. ASUS servers are PCIe 5.0 ready, with scalable designs to satisfy the increasing workloads or modern data centres.

Keep Your Data Centre Green

Data centres can consume huge amounts of electricity, raising environmental concerns. ASUS servers are designed to optimize both total cost of ownership (TCO) and total cost to the environment (TCE), including thermal design, power efficiency and advanced cooling solutions — reducing the impact of our products on the planet.

Comprehensive IT Infrastructure Solutions

Advanced ASUS management tools comprise IT assets management, security and reliability to improve the performance, up-time and real-time monitoring of the servers remotely — highly increasing the efficiency of IT infrastructure.

Tool-Less Cover

ASUS servers feature three easy-access covers that can be opened without tools, enabling IT staff to perform maintenance on specific components without removing the server fully from the rack.

Front-Bezel Q-Code

ASUS servers have a visible Q-Code/port-80 LED display LED for simple monitoring of the entire boot process, from power on through loading of the operating system.

Hot-Swap Design

ASUS servers feature multiple hot-swap components, including fans, power supplies and storage for easy troubleshooting to keep 24/7 seamless operations.
