Lenovo 1611-8P NVMe Switch Adapter 4Y37A09737 | PCIe 4.0, Server

Keep NVMe storage paths efficient in servers that demand direct access and flexible expansion. The Lenovo 1611-8P PCIe Gen4 Switch Adapter is built as a plug-in card for server platforms, with a low-profile design that fits dense chassis and a PCIe 4.0 x16 host interface for modern bandwidth requirements. This adapter supports JBOD operation and is intended for environments where storage orchestration is handled by the operating system or software stack rather than by a traditional RAID controller. That makes it a practical choice for NVMe-centric deployments, storage nodes, and server builds that need straightforward drive connectivity without unnecessary controller overhead. With eight SAS ports exposed through four x8 SFF-8654 connectors, the 1611-8P is aimed at infrastructure teams that need a compact way to attach multiple drives while keeping the storage layer predictable. It is the kind of component that earns its place in higher-value server designs: not by adding complexity, but by preserving performance and simplifying the path from PCIe fabric to storage media.
