  • Plug-and-play design allows quick, efficient deployment with minimal configuration

Product Overview

The Lenovo 4Z57A14185 cable is a high-speed 2-meter Direct Attach Cable (DAC) that utilizes Mellanox HDR InfiniBand technology and QSFP56 connectors to enable fast and reliable data transmission. This type of cable is engineered for short-range data communication between high-performance servers, switches, and storage systems, typically within data center rack configurations. The QSFP56 interface provides enhanced bandwidth performance suitable for high-throughput applications.

Built for environments demanding low latency and high bandwidth, this cable is a cost-effective solution for connecting hardware within close proximity without the need for active optical components. The passive DAC design helps reduce power consumption while maintaining performance consistency. Though the country of origin and TAA compliance status are unspecified, the Lenovo branding assures integration compatibility with Lenovo enterprise systems and third-party Mellanox-compliant equipment.

This cable is particularly beneficial in HPC (High-Performance Computing), AI workloads, and other bandwidth-heavy operational scenarios. Its compact size and simple plug-and-play functionality streamline deployment, contributing to time savings and network efficiency.
