Lenovo 7159GR6 G8296 2U Rack Switch

Overview

The Lenovo 7159GR6 is a 2U rack-mount data center switch designed to deliver high-density connectivity with eighty-four 10 Gb SFP+ ports and ten 40 Gb QSFP+ ports. It supports rear-to-front airflow to optimize cooling in dense rack environments. Built on a non-blocking Ethernet architecture, this switch ensures low latency and full line-rate performance across all ports, making it suitable for demanding server aggregation and core networking roles.

Its flexible SFP+ interfaces accept both direct attach copper and optical fiber cables, allowing you to tailor connections based on distance and cost. The QSFP+ ports can function as high-capacity uplinks or be broken out into multiple 10 Gb links, providing versatility for scaling bandwidth to additional servers or top-of-rack devices.

Key features

• High port density with eighty-four 10 Gb SFP+ ports to connect numerous servers or devices within a rack.
• Ten 40 Gb QSFP+ ports that support breakout to 10 Gb connections, enabling flexible bandwidth distribution.
• Rear-to-front airflow design that aligns with typical data center cooling strategies for efficient heat management.
• Non-blocking Ethernet switching fabric that maintains consistent throughput and low latency under heavy traffic.
• SFP+ interfaces compatible with both direct attach copper and fiber optic cables, offering cost and distance flexibility.
