The Mellanox MSB7800 operates as a non-blocking L2/L3 fabric switch, supporting adaptive routing, static routing, and hardware-based congestion control—positioning it as a foundational building block for fat-tree, dragonfly, and hypercube topologies in high-performance compute and storage clusters. This 1U rack-mount switch from Mellanox (NVIDIA), part number MSB7800-CS2F, delivers 36 × 100Gb/s QSFP28 EDR InfiniBand ports with 7.2 Tb/s bidirectional aggregate bandwidth and 3.6 Tb/s non-blocking throughput. The Mellanox Quantum ASIC achieves sub-100 nanosecond port-to-port latency, enabling deterministic low-latency communication essential for RDMA workloads. Native InfiniBand RDMA support, combined with hardware QoS featuring multiple virtual lanes and service levels, ensures predictable performance for mixed workload environments. Redundant hot-swap power supply modules and redundant hot-swap fan modules with front-to-back airflow provide operational resilience, while the out-of-band 1GbE RJ45 management port supports CLI, SNMP, REST API, and OpenSM subnet management for flexible integration into existing infrastructure.

Data center architects, HPC network engineers, and AI infrastructure teams deploy the MSB7800-CS2F when building next-generation interconnects for machine learning clusters, financial simulations, and petascale storage systems where microsecond-level latency and zero-loss fabric reliability are non-negotiable. The 100 Gb/s per-port throughput and adaptive routing eliminate traditional bottlenecks, while the switch's compact form factor maximizes port density within standard rack constraints. Organizations standardizing on EDR InfiniBand for their core fabric choose this platform to achieve predictable, scalable performance across thousands of compute nodes without oversubscription.

The MSB7800-CS2F is engineered for operating environments between 0°C and 40°C and qualifies for mission-critical deployments where fabric availability directly impacts revenue and research outcomes.
