Architectural & Feature Highlights

1. Ultra-High GPU Compute Density

Packed into a compact 4U chassis, the NF5488M5 accommodates 8 SXM-based NVIDIA GPUs along with dual high-performance Intel CPUs, delivering multi-petaflops of AI performance in a single system.

2. High-Bandwidth Interconnect (NVSwitch)

By utilizing NVIDIA NVSwitch technology, all 8 GPUs communicate at full NVLink line rates (600 GB/s bi-directional bandwidth per GPU). This bypasses traditional PCIe bottlenecks, allowing seamless distributed training on large datasets and deep learning parameters.

3. Balanced I/O with GPUDirect RDMA

The system supports up to 8 high-speed network interfaces (such as InfiniBand HDR 200Gbps or Ethernet NICs) configured in a direct 1:1 map to each GPU. This architecture maximizes multi-node scaling performance using GPUDirect RDMA (GDR).

4. Optimized Thermal & Power Efficiency

• Custom-designed air ducts segregate CPU and GPU thermal zones, maintaining stable high-frequency clock rates under prolonged 100% compute loads.

• Hot-swappable, redundant power supplies ensure maximum uptime and energy efficiency in modern hyperscale datacenters.

Target Application Scenarios
