About the Mellanox MSB7800 - 100/400GbE
The Mellanox MSB7800 - 100/400GbE switch delivers enterprise-grade redundancy with hot-swappable power supplies and fan modules, ensuring continuous operation in mission-critical data center environments. Built on the Mellanox Switch-IB 2 ASIC, this 1U rack-mount switch (part number MSB7800-CS2R) combines ultra-low latency with exceptional throughput, making it the preferred choice for network engineers and infrastructure teams deploying high-performance computing and storage clusters.
With 36 QSFP28 ports operating at 100Gb/s per port, the Mellanox MSB7800 delivers a non-blocking, cut-through forwarding architecture with sub-100 nanosecond port-to-port latency—critical for demanding enterprise workloads. The switch supports multiple protocols including InfiniBand HDR100, 100GbE, 40GbE, 25GbE, and 10GbE via breakout, providing flexible deployment options across heterogeneous network environments. Management is streamlined through NVIDIA Onyx operating system, out-of-band 1GbE management, and compatibility with NVIDIA Unified Fabric Manager (UFM). The switch operates reliably across standard data center temperature ranges with AC 100–240V input.
