ASUS ESC N4A-E11/A100 AMD EPYC Barebones Server, 4U, 3x PCIe Gen4, 4x Hot-Swap Bays, 2x RJ45
ESC N4A-E11
NVIDIA® HGX A100 AI server featuring four A100 Tensor Core GPUs, an AMD EPYC™ 7003 CPU, four storage bays, one M.2, three PCIe® 4.0 slots, 80 PLUS® Titanium power supply, ASUS ASMB10-iKVM and OCP 3.0.
AI Server for Simulation and Data Analytics
ASUS ESC N4A-E11 is an AMD EPYC 7003 server for AI supercomputing performance and leverages the NVIDIA HGX A100 baseboard designed to efficiently accelerate large complex AI workloads and HPC performance, with four Multi-Instance GPU (MIG)-capable Tensor Core GPUs to fully interconnect with up to 320 GB of total GPU memory. The system’s optimised thermal design enables support for an up to 400 W GPU* to deliver unprecedent performance for data analytics, AI and simulation.
Direct GPU-to-GPU Interconnect
The four A100 GPUs on the HGX baseboard of ESC N4A-E11 are directly connected through third-generation NVLink, enabling all GPUs to work as one on large AI models, with high-bandwidth communication for efficient scaling. The A100-to-A100 peer bandwidth is up to 200 GB/s bi-directional, for speeds that are up to 2X faster than a PCIe 4.0 x16 bus.
AMD EPYC 7003 Processors
Built for AI supercomputing, ESC N4A-E11 features a single-socket AMD EPYC 7003-series processor offering the highest performance for AI and HPC workloads and supports a TDP of 280 W and extensive memory capacity of 16 DIMM slots populated with 8-channel DDR4-3200 memory per processor.
High-Speed Connectivity
PCIe 4.0 delivers 16 GT/s bandwidth, which is double the speed of PCIe 3.0, offering lower power consumption, better lane scalability and backwards compatibility. ESC N4A-E11 features three PCIe 4.0 expansion slots and supports up to 200 GB Mellanox HDR InfiniBand smart network interface controllers to deliver extreme-speed network connections.
NVIDIA GPUDirect Storage
Featuring four 3.5-inch hot swap drive bays supporting up to two NVMe SSDs on front panel and one M.2 onboard that enables extensive storage and high-throughput performance. ESC N4A-E11 supports GPUDirect Storage to provide a direct path between storage and GPU memory, avoiding extra copies through a bounce buffer in the CPU’s memory.
Titanium Power Supply
ESC N4A-E11 supports 3000 W 80 Plus Titanium redundant power supplies which are 96%+ efficient, directly reducing operating costs and offering easier servicing. The 1+1 power-supply design allows the server to keep working even if one power supply requires maintenance, enabling uninterrupted operation.
Enhanced Security
ASUS ESC N4A-E11 servers integrate PFR FPGA as the platform Root-of-Trust solution for firmware resiliency to prevent from hackers from gaining access to infrastructure. ASUS security solutions are fully compliant with the 2018 National Institute of Standards and Technology (NIST) SP 800 193 specification.
In addition, all ESC N4A-E11 servers also include support Trusted Platform Module 2.0 (TPM 2.0) to secure hardware through integrated cryptographic keys and offer regular firmware update for vulnerabilities.
