Lenovo ThinkSystem 2U x16/x8/x8 PCIe G4 Riser 1/2 option Kit

The Lenovo ThinkSystem 2U x16/x8/x8 PCIe G4 Riser 1/2 option Kit is a high-performance, enterprise-class solution designed to unlock maximum PCIe bandwidth and flexible I/O expansion for ThinkSystem 2U servers. Built for data centers, virtualization, AI workloads, and storage-intensive deployments, this Gen4 PCIe riser kit enables you to tailor your configuration to the exact needs of your workloads. With robust construction, streamlined installation, and a design optimized for cooling and reliability, this kit helps you scale your server capabilities while preserving space, efficiency, and serviceability in demanding environments.

• Flexible PCIe lane configuration for dynamic workloads: The kit supports x16, x8, and x8 lane mappings, enabling versatile attachment of graphics accelerators, high-speed NICs, and storage controllers. By allowing you to optimize PCIe wiring for your specific workload, you can maximize throughput where it matters most while preserving room for additional devices. This flexibility is especially valuable in virtualized environments, high-performance computing (HPC) clusters, and AI inference tasks that require substantial PCIe bandwidth without sacrificing overall system balance.
• Gen4 performance and compatibility: Leveraging PCIe Gen4 (PCIe 4.0) technology, the riser delivers significantly higher bandwidth than Gen3 solutions, accelerating data movement between the host motherboard and PCIe cards. The kit is designed to integrate seamlessly with Lenovo ThinkSystem 2U servers, ensuring reliable operation within established data-center ecosystems and simplifying maintenance and upgrades over time.
• Engineered for reliability and serviceability: Lenovo ThinkSystem components are backed by enterprise-grade reliability. The riser kit uses robust connectors, precision alignment, and a rigid frame to minimize signal integrity issues and vibration. Designed for easy field service, it supports quick installation and replacement, reducing downtime and total cost of ownership in busy data centers.
• Thermal-aware design and airflow optimization: The riser geometry and component layout are optimized to support effective cooling within the 2U chassis. By maintaining clear air paths and reducing unnecessary cable clutter, the kit helps sustain stable temperatures even when multiple PCIe cards operate at high power. This contributes to consistent performance during demanding workloads and helps prevent thermal throttling.
• Simplified installation for scalable deployment: The 1/2 option kit is engineered for straightforward deployment within Lenovo tooling and standard PCIe card spacing. It uses familiar mounting points and connectors, enabling rapid expansion during initial builds or after capacity growth—without extensive downtime or complex cabling. This scalable approach protects your hardware investment while enabling rapid response to changing data-center needs.
