NVIDIA DGX A100 InfiniBand is the protocol of choice for creating high bandwidth, low-latency networks linking NVIDIA GPU-based systems to other DGX and DPU systems. The DGX A100 supports eight 200Gb/s HDR host channel adapters (HCAs) linking to other DGX systems via Quantum network switches. Two 200Gb/s HDR InfiniBand or Ethernet interface cards link to storage HDD, SSDs and flash memory subsystems. InfiniBand HDR DACs reach up to 2m and Etherent up to 2.5m, perfect for in-rack applications and for longer reaches, ACCs can reach up to 4m. LEARN MORE ›
