A Primer Guide of InfiniBand Cables

InfiniBand cables are instrumental components in high-performance computing and data center networks, facilitating rapid data transfer and low-latency communication. As the volume of data processed and transmitted continues to grow exponentially, the importance of InfiniBand cables in ensuring seamless connectivity and optimal performance cannot be overstated. This article will briefly introduce the structure and classification of infiniBand cables.

Understanding InfiniBand Cables

At its core, InfiniBand is a high-speed interconnect technology designed to connect servers, networking equipment, storage systems, and embedded devices within data centers. InfiniBand cables serve as the physical medium for transmitting data between these interconnected nodes, employing a channel-based architecture to facilitate high-speed communication.

Operation Principles of InfiniBand Cables

InfiniBand cables utilize a switched fabric architecture, where data packets are transmitted between nodes via channel adapters. Each processor node is equipped with a host channel adapter, while peripheral devices are equipped with target channel adapters. These adapters exchange information to ensure secure and efficient data transmission, operating at predefined quality of service (QoS) levels.

Cables play a pivotal role in ensuring the performance, scalability, and future adaptability of InfiniBand networks. In pursuit of scalable performance, InfiniBand adopts a multilane cable architecture, where a serial data stream is distributed across multiple parallel physical links operating at identical signaling rates. The figure shows three link widths of 1, 4, and 12 parallel lanes, referred to as 1X, 4X, and 12X. 

Common Types of InfiniBand Cables

InfiniBand cables come in various types to accommodate different connectivity requirements and environments. Some of the most common types include active optical cable (AOC), direct attach copper cable (DAC), and active copper cable (ACC). Each type has its own unique characteristics, advantages, and use cases, allowing for flexible deployment options in diverse networking scenarios. In comparison to traditional Category 5e and Category 6 UTP cabling, InfiniBand cables exhibit greater thickness, bulkiness, and weight. Their susceptibility to bend radius necessitates careful handling during installation, emphasizing the importance of proper strain relief to uphold connection reliability over time.
