SB7780/7880 InfiniBand Series

Switch-IB 2 EDR 100Gb/s InfiniBand Router Switch

The unprecedented growth of the global HPC market coupled with the insatiable demands of Exascale ecosystems around the world, have caused a rapid increase in the number of connected servers. The NVIDIA Mellanox SB7780/SB7880 InfiniBand Routers allow scaling up to an unlimited number of nodes, while sustaining the data processing demands of machine learning, IoT, HPC and cloud applications.

Resiliency and Ease of Scale

The InfiniBand router brings two major enhancements to the Mellanox switch portfolio. increasing resiliency, the router segregates the data center network into several subnets. Each subnet runs its own subnet manager, effectively isolating each subnet from the others’ availability or instability. Additionally, the router also enables the fabric to scale up to an unlimited number of nodes.
