SB7890: 36-Port EDR 100Gb/s InfiniBand Smart Switch System
1. Product Overview
The Mellanox SB7890 is a high-performance, 36-port EDR InfiniBand switch system designed for modern data centers and high-performance computing (HPC) environments. It delivers non-blocking bandwidth of up to 7.2Tb/s with ultra-low latency of 90ns, making it an ideal network switch solution for demanding applications.
2. Key Features
- 36 non-blocking EDR 100Gb/s InfiniBand ports
- 7.2Tb/s aggregate throughput with 90ns latency
- Support for adaptive routing and congestion control
- In-network computing with SHARP™ technology
- Hot-swappable, redundant power supplies and fans
- Energy-efficient design with typical power consumption of 122W
3. Core Technology
The SB7890 leverages Mellanox's Switch-IB® 2 technology, supporting InfiniBand Trade Association (IBTA) 1.2/1.3 standards. It incorporates Co-Design SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) to offload collective communication operations, significantly accelerating MPI and SHMEM protocols.
4. How It Works
The switch processes data in transit using embedded hardware, reducing the need for multiple data transmissions between endpoints. This approach minimizes network traffic and frees up CPU resources for computation, enhancing overall application performance.
5. Applications
Ideal for HPC clusters, enterprise data centers, AI/ML workloads, and large-scale storage environments. Supports modern topologies including SlimFly, Dragonfly+, and Torus.
