A20 A03 GPU Server

Quad-GPU Compute Powerhouse

  • Four RTX 5090 GPUs: Supports up to four NVIDIA GeForce RTX 5090 graphics cards for parallel processing. Each GPU features 32 GB of GDDR7 memory, delivering multi-petaflop performance for AI models, simulations, and rendering. With the latest Blackwell architecture and enhanced Tensor Cores, the A20 A03 can handle the largest training workloads and graphics projects.
  • Industry-Leading Bandwidth: The server’s architecture gives each GPU full PCIe 5.0 x16 connectivity, enabling 64 GB/s bidirectional throughput. This maximizes data flow between GPUs and CPUs, ensuring no bottleneck when training large neural networks or crunching massive datasets.

Advanced Thermal Management

  • Hybrid Cooling Design: A20 A03 features a liquid-cooled CPU solution and seven variable-speed hot-swap fans. This hybrid approach pulls heat away from the processor with an integrated loop while high-flow fans ventilate the GPUs. The result is stable, high-performance operation even under sustained full-load.
  • Optimized Airflow Architecture: The chassis uses separate airflow tunnels for CPU and GPU sections. By isolating heat sources, exhaust air from the graphics cards is guided out the back while fresh air cools the CPU, and vice versa. This design minimizes thermal interference and keeps all components within optimal temperature ranges.

  • Massive Memory Footprint: Twelve DIMM slots (12 channel DDR5) support up to 3072 GB of ECC-registered memory. Enterprise-grade ECC DIMMs detect and correct errors on the fly, ensuring data integrity for long-running computations and mission-critical AI jobs.
  • Breakthrough Performance: DDR5 memory (up to 4800 MHz+) provides huge bandwidth to feed GPUs and CPUs. This deep memory pool and wide bus mean you can train enormous models (billions of parameters) without hitting memory limits, future-proofing your workloads as datasets grow.

1xM.2 2280/22110 PCIe 3.0x4 port

1xM.2 2280/22110 PCIe 3.0x2 port


  • High-Density NVMe: Dual internal M.2 slots (one full x4 slot) plus 12 front-panel 2.5〃 hot-swap bays enable extensive NVMe/SAS/SATA storage. The bays accept U.2 NVMe drives, letting you configure petabyte-scale, high-speed storage arrays for data lakes and checkpointing.
  • Flexible Expansion: In addition to storage, the A20 A03 offers two PCIe 4.0 x8 slots  for extra NICs or RAID controllers. This allows for 100/200 GbE networking or additional NVMeoF adapters. Hot-swap bays and sliding trays mean you can add drives or swap components without system downtime.

Lightning-Fast PCIe Gen5 I/O

  • PCIe 5.0 Everywhere: Built on an AMD EPYC Genoa platform, the A20 A03 provides up to 128 PCIe 5.0 lanes. Four GPU slots use PCIe 5.0 x16, and multiple additional slots support PCIe 5.0 peripherals. This means GPU accelerators, NVMe drives, and network cards all enjoy double the bandwidth of PCIe 4.0. 
  • Future-Ready Expansion: Two extra PCIe 4.0 x8 slots are included for high-speed network adapters or additional accelerators. Combined with onboard PCIe lanes, this design lets data-center managers add the fastest Ethernet or InfiniBand cards without sacrificing GPU bandwidth.

Redundant High-Efficiency Power

Redundant High-Efficiency Power

  • Titanium-Class Power Supplies: For 24/7 reliability, the A20 A03 supports redundant power modules. Configurations can include dual (1+1) or quad supplies (up to 3000 W each). Using 80 PLUS Titanium-rated units, the system delivers power with >96% efficiency, reducing heat and energy costs even under heavy GPU loads.
  • Uninterrupted Uptime: Redundant PSUs and ECC memory work together to prevent single points of failure. If a power module or a DIMM were to fail, hot-swap capability and error-correction ensure the server stays online. This level of redundancy is critical for enterprise deployments and data-center operations.

AI/HPC-Optimized Performance

  • Engineered for AI and HPC: The A20 A03 is tuned for deep learning and scientific computing. It benefits from NVIDIA’s 5th-generation Tensor Cores and AI features, dramatically accelerating training and inference. Independent benchmarks show the RTX?5090 achieves significant gains in AI throughput, up to ~41% faster than the prior generation, making it ideal for model development and data analytics.
  • Rich Software Ecosystem: Fully compatible with CUDA, cuDNN, TensorRT, and popular frameworks (TensorFlow, PyTorch, etc.), the server plugs into existing AI pipelines with no compromise. Built-in support for GPU virtualization (NVIDIA vGPU) and high-speed interconnects also means it can handle large-scale parallel simulations and visualization workloads.

Future-Proof Architecture

Redundant High-Efficiency Power

Rack-Optimized Build and Serviceability

  • Next-Generation Chipset: Powered by an AMD EPYC 9004-series (“Genoa”) CPU, the server offers up to 96 cores / 192 threads with 12-channel DDR5 memory and 128 PCIe 5.0 lanes. This modern platform supports current and upcoming CPU and GPU standards (PCIe?5.0, CXL for memory expansion, etc.), ensuring the investment stays relevant through future hardware upgrades.
  • Modular Design: With Gen-Z and CXL support emerging, administrators can later integrate new accelerators (like programmable SmartNICs or advanced AI chips) using the abundant I/O. The chassis also has room for additional cards or drives as needs grow. Enterprise-Class Management & Reliability

  • Standard 4U Rackmount: The compact 19〃, 4U chassis fits common data-center racks. An included heavy-duty slide-rail kit makes deployment and servicing quick and tool-less. Front-access hot-swap bays and side panels allow drives, fans, and GPUs to be replaced without removing the server from the rack.
  • Robust Construction: Made from high-gauge SGCC steel, the chassis is both lightweight and strong. It carries full FCC, CE, and RoHS certifications, meeting global safety and EMI standards. These design details minimize downtime and support continuous operation in demanding enterprise environments.
