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.
