The Lenovo ThinkSystem NE1072T RackSwitch that uses 10GBASE-T and 40 Gb QSFP+ Ethernet technology is specifically designed for the data center. It is ideal for today's big data, cloud, and enterprise workload solutions. It is an enterprise class Layer 2 and Layer 3 full featured switch that delivers line-rate, high-bandwidth switching, filtering, and traffic queuing without delaying data. Large data center-grade buffers help keep traffic moving, while the hot-swap redundant power supplies and fans (along with numerous high-availability features) help provide high availability for business sensitive traffic.

This product guide provides essential pre-sales information to understand the NE1072T RackSwitch, its key features and specifications, components and options, and configuration guidelines.

This guide is intended for technical specialists, sales specialists, sales engineers, IT architects, and other IT professionals who want to learn more about the NE1072T RackSwitch and consider its use in IT solutions.
