Description

Lenovo 4Z57A72558 QSFP112 Cable

Overview

The Lenovo 4Z57A72558 is a QSFP112 cable designed for high-speed data center interconnects, specifically supporting 200GbE (Gigabit Ethernet) and InfiniBand protocols. This cable is critical for linking servers equipped with NVIDIA ConnectX-7 adapters, enabling maximum throughput for demanding workloads like AI, HPC, and large-scale data analytics. It facilitates direct server-to-server or server-to-switch connections where bandwidth is paramount.

Compatibility

This cable is engineered for compatibility with Lenovo ThinkSystem servers featuring specific NVIDIA ConnectX-7 adapters, including the ThinkSystem SD650 V3 NVIDIA ConnectX-7 NDR200/HDR/200GbE QSFP112 2-Port PCIe Gen5 x16 Adapter (SharedIO) DWC (part number 4XC7A86669). It is also compatible with other systems utilizing the same QSFP112 interface for 200GbE or NDR InfiniBand connectivity.

Installation Notes

Ensure that the QSFP112 ports on both the server adapter and the connected device are clean and free of obstructions. The cable should be seated firmly in the SFP ports to ensure a stable connection and optimal signal integrity. For optimal performance, verify that the server's firmware and drivers are updated to support the full 200GbE or NDR InfiniBand speeds.
