WHY CHOOSE THIS PRODUCT?

• MSB7880-ES2R is a strong fit for existing Switch-IB 2 EDR InfiniBand environments requiring dense 36-port 100Gb/s routing, dual AC power and C2P airflow. Its 1U design, high aggregate throughput and integrated management capabilities support efficient HPC and AI fabric expansion, while the router architecture provides a practical option for connecting InfiniBand subnets. Because NVIDIA identifies this model as EOL, procurement teams should verify availability, existing-fabric compatibility and lifecycle requirements before selecting it for a new deployment.
