FS NVIDIA Mellanox InfiniBand Switch Overview

In today's digital era, fast data transmission is crucial in the fields of modern computing and communication. NVIDIA Mellanox InfiniBand switches play a key role in data center networks to meet the demands of large-scale data transfer and high-performance computing. This article will introduce the fundamentals of InfiniBand technology, the functionalities and features of Mellanox InfiniBand switches, and their applications in various domains.

InfiniBand architecture is a powerful new architecture designed to support I/O connectivity for the Internet infrastructure, which brings fabric consolidation to the data center. Storage networking can concurrently run with clustering, communication and management fabrics over the same infrastructure, preserving the behavior of multiple fabrics.

InfiniBand is an open-standard network connecting technology with high bandwidth, low latency, and excellent dependability. IBTA (InfiniBand Trade Alliance) defines this technology, which is commonly utilized in supercomputer clusters. Simultaneously, with the advent of artificial intelligence, it is becoming the primary network interconnection solution for GPU servers.

With its expertise and technological strength in the field of InfiniBand, NVIDIA offers a range of powerful InfiniBand switches. These NVIDIA/Mellanox InfiniBand switches, equipped with core functionalities such as routing, forwarding, and data flow management, enable efficient data transmission and communication. NVIDIA's product line covers a wide range of scalability, performance, and functional requirements, providing users with flexible choices. The table below showcases the Mellanox InfiniBand switches available from FS.

Note: In the table, P in P2C and C2P means power, C means cable (line interface), P2C (Power to Cable), C2P (Cable to Power). The reference system here is that the cable line interface side is the front, and the power side is the back.

There are two options for the 200G HDR and 400G NDR InfiniBand switches: QM8700 and QM8790 for the 200G switch, and QM9700 and QM9790 for the 400G switch. The only difference between the two options is management mode. The QM8700 and QM9700 provide the control interface for out-of-band management, while the QM8790 and QM9790 require the NVIDIA Unified Fabric Manager (UFM®) platform for management. In addition, please note that the port encapsulation of the Mellanox 200G HDR InfiniBand switch is OSFP56, and the port encapsulation of the Mellanox 400G NDR InfiniBand switch is OSFP.
