Mellanox MSB7890-ES2F 36-Port EDR 100Gb/s InfiniBand Switch – 7.2Tb/s
The Mellanox MSB7890-ES2F is a high-performance 1U InfiniBand switch designed for high-performance computing (HPC), AI, scientific computing and data-intensive data center environments. Based on Mellanox Switch-IB 2 technology, it provides 36 QSFP28 ports with EDR InfiniBand connectivity and up to 7.2Tb/s of aggregate non-blocking bandwidth.
The MSB7890-ES2F is the P2C airflow version, meaning the connector side is the outlet side for airflow. The system includes two AC power supplies and is specified by Mellanox as an unmanaged switch, making it suitable for fabrics where management and subnet management are provided externally.

Mellanox MSB7890-ES2F InfiniBand Technology
The MSB7890-ES2F uses Mellanox Switch-IB 2 technology to provide high-bandwidth EDR InfiniBand switching. Its non-blocking architecture allows the 36 ports to operate at 100Gb/s while providing up to 7.2Tb/s aggregate switching bandwidth.
The platform supports advanced InfiniBand fabric features including adaptive routing, congestion control, virtual lane mapping and port mirroring. These capabilities are useful for maintaining predictable communication performance in large-scale HPC and data center fabrics.
SHARP In-Network Computing
The SB7890 platform supports Mellanox SHARP technology for in-network collective communication processing. SHARP can offload supported collective operations to the network fabric, reducing communication overhead for suitable HPC, MPI and data-intensive workloads.
MSB7890-ES2F Airflow and Power
The MSB7890-ES2F uses P2C airflow, where the connector side is the airflow outlet. It is equipped with two 460W AC power supplies and a redundant power architecture. The related MSB7890-ES2R model uses the opposite C2P airflow configuration, so airflow direction should be confirmed before rack installation.
Applications
- High-performance computing clusters
- AI and machine learning infrastructure
- Scientific and research computing
- Large-scale InfiniBand data centers
- GPU compute clusters
- Distributed storage environments
- HPC networking and MPI workloads
- Low-latency server-to-server fabric connectivity
Mellanox MSB7890-ES2F Compatibility
The switch uses 36 QSFP28 InfiniBand ports and can be connected to compatible InfiniBand adapters, DAC cables, AOCs and optical transceivers. The exact adapter, cable and optic combination should be validated for the required InfiniBand generation, signaling rate and link distance.
Because the MSB7890-ES2F is an unmanaged/external-management variant, an appropriate external InfiniBand subnet management solution is required for fabric operation. Deployment compatibility should therefore be checked with the planned subnet manager, management platform, adapters and switch firmware.
