Lenovo ThinkSystem SN550/SN850 Fabric Connector

The Lenovo 7M27A03927 is a fabric connector for ThinkSystem SN550 and SN850 servers that lets you expand network capacity without re-cabling or retrofitting the entire rack. By adding this module, an administrator can open additional lanes for data traffic, help reduce bottlenecks, and keep applications responsive as workloads grow.

Installation is straightforward. The connector slides into the designated bay on the SN550 or SN850, and the system automatically recognizes the new resource. There is no need for specialized tools or prolonged downtime, which means you can schedule the upgrade during a regular maintenance window and have the server back online quickly.

This module fits naturally in branch offices, edge locations, and mid-sized data centers where space and budgets are tight but reliability is non-negotiable. Teams that run virtualization clusters, high-volume transaction databases, or private cloud services will appreciate the consistent throughput and the headroom it provides for future network growth.

Because the connector is engineered by Lenovo for its own ThinkSystem platform, it aligns with the same quality and testing standards as the servers themselves. That integration helps ensure dependable performance over long operating cycles and reduces compatibility concerns, giving IT staff one less point of failure to manage.

The result is a cost-effective path to scale network bandwidth that respects both time and budget, while keeping critical systems stable and responsive.
