SB7800 Infiniband Series

Switch-IB 2 EDR 100Gb/s InfiniBand Smart Edge Switches

NVIDIA® Mellanox® SB7800 switches provide up to 36 ports of 100Gb/s full bi-directional bandwidth. Available in both managed and externally managed models, SB7800 switches are ideal for top-of-rack leaf connectivity or for small to extremely large clusters. Today’s high-performance computing (HPC) and AI environments need every bit of bandwidth delivered by these Enhanced Data Rate (EDR) InfiniBand high-speed smart switches.

High Resilience

Built with NVIDIA Mellanox’s Switch-IB® 2 InfiniBand switch application-specific integrated circuit (ASIC), the SB7800 series provides up to 36 ports of 100Gb/s full bi-directional bandwidth. The SB7800 smart network switch enables NVIDIA In-Network Computing through NVIDIA Mellanox Scalable Hierarchical Aggregation Protocol (SHARP) technology.

In-Network Computing

In-Network Computing

NVIDIA Mellanox InfiniBand SHARP, In-Network Computing offloads collective communication operations from the CPU to the switch network, decreasing the amount of data traversing the network, dramatically reducing the time of Message Passing Interface (MPI) operations, and improving application performance by an order of magnitude.

Self-Healing Networking

Self-Healing Networking

NVIDIA Mellanox InfiniBand with self-healing networking capabilities overcomes link failures and achieves network recovery 5,000X faster than any software-based solution—enhancing system performance, scalability, and network utilization.

UFM Management

UFM Management

NVIDIA Mellanox Unified Fabric Management (UFM®) platforms combine enhanced, real-time network telemetry with AI-powered cyber intelligence and analytics to realize higher utilization of fabric resources and a competitive advantage, while reducing OPEX.
