Description

InfiniBand Direct Attach Cable (DAC)

An InfiniBand Direct Attach Cable (DAC) is a high-performance Twinax copper cable designed for ultra-low latency data transmission in High-Performance Computing (HPC) and AI clusters. It uses the InfiniBand protocol to provide the fastest possible electrical path for short-range interconnects.

Technical Description for InfiniBand Direct Attach Cable (DAC)

InfiniBand DACs are engineered for maximum signal integrity in high-density environments.
  • Protocol Specific: Designed to meet InfiniBand Trade Association (IBTA) standards, ensuring lower Bit Error Rates (BER) compared to generic Ethernet cables.
  • Zero-Latency Design: By avoiding electrical-to-optical conversion, DACs offer near-zero latency, which is critical for synchronized parallel processing in supercomputers.
  • Passive & Powerless: Most InfiniBand DACs are passive, consuming zero power and generating no additional heat, making them the most energy-efficient interconnect option.
  • Form Factors: Available in QSFP56 (200G HDR), QSFP112 (400G NDR), and OSFP (800G NDR) to match the latest generations of networking hardware.

Key Applications for InfiniBand Direct Attach Cable (DAC)

  • AI Training Clusters: Interconnecting GPU servers (e.g., NVIDIA DGX) to InfiniBand switches within a single rack.
  • Supercomputing (HPC): Linking compute nodes for scientific simulations where timing is critical.
  • High-Speed Storage: Connecting NVMe storage arrays to the InfiniBand fabric for rapid data access.
