NVIDIA Mellanox MCX353A-FCBT 56Gb/s FDR InfiniBand Adapter

NVIDIA Mellanox MCX353A-FCBT 56Gb/s FDR InfiniBand Adapter

Brand:

Mellanox

NVIDIA Mellanox MCX353A-FCBT is a single-port ConnectX-3 VPI adapter for 56Gb/s FDR InfiniBand connectivity in PCIe-based servers. Its QSFP+ interface, PCIe Gen3 x8 host connection, low-profile form factor, and support for Ethernet modes make it suitable for HPC, enterprise data centers, and storage environments.

OVERVIEW

NVIDIA Mellanox MCX353A-FCBT is a ConnectX-3 VPI single-port adapter designed to add high-speed InfiniBand connectivity to PCIe-based servers. It supports up to 56Gb/s FDR InfiniBand and also provides Ethernet connectivity, giving infrastructure teams protocol flexibility within supported environments. The QSFP+ interface and PCIe Gen3 x8 host connection suit HPC clusters, enterprise data centers, and storage infrastructure. Compared with dual-port ConnectX-3 variants, this model uses one network port, making it a focused option for servers requiring a single high-speed fabric connection and low-profile deployment.
