Product Review

The Mellanox MSX6720-FS2F2 Switch, featuring SwitchX®-2 based FDR InfiniBand and 36 QSFP+ ports, offers high bandwidth capacity at 2.88Tb/s, suitable for demanding data center environments. However, with only 4G of SDRAM and a single SSD slot supporting up to 64G, its memory capacity may limit performance in highly intensive tasks. Additionally, its dual power supplies and standard depth design with rear to front airflow ensure reliable operation, though the system's overall performance is constrained by its fixed port speed of 40/56Gbps and Ethernet technology at 40 Gbps.


The Mellanox MSX6720-FS2F2 is a 1U switch designed to deliver high-speed networking with its SwitchX®-2 based FDR InfiniBand technology. This switch is equipped to handle demanding data environments with 36 QSFP+ ports, allowing for a total capacity of 2.88Tb/s, making it suitable for data centers and high-performance computing requirements. Key specifications include port speeds of 40/56Gbps and Ethernet technology capable of 40 Gbps, ensuring rapid data transfer rates. The system's memory is configured with a 16G SSD, which can be expanded up to 64G on a single SSD slot, and 4G of SDRAM, supporting efficient processing and storage capabilities.
