Powered by NVIDIA Quantum-2 technology, this NDR 400Gb/s InfiniBand switch delivers high-speed, low-latency connectivity with full bidirectional bandwidth. The non-blocking architecture ensures consistent throughput across all ports, enabling efficient communication for large-scale AI clusters, HPC environments, and data-intensive applications.
Featuring 1+1 redundant hot-swappable AC PSUs and 6+1 redundant hot-swappable fans, the switch supports uninterrupted maintenance and enhances system reliability for high-performance AI and HPC networks.
NVIDIA SHARPv3 technology improves AI and HPC workload efficiency by offloading collective communication operations from CPUs and GPUs to the InfiniBand network. By performing aggregation and reduction operations within the network, SHARP reduces data movement, lowers communication overhead, and accelerates large-scale distributed computing.
Adaptive Routing intelligently adjusts traffic paths based on network conditions, reducing congestion and improving workload scalability for distributed AI training and high-performance computing applications.
Enhanced Network Resilience with Self-Healing Capabilities
The self-healing architecture enables rapid fault detection and recovery, helping maintain stable network operations and improve availability in mission-critical computing environments.
