PCIe 3.0 x8 to dual SFF-8643 NVMe switch adapter for high-bandwidth storage expansion.
When server PCIe slots are scarce but storage demands grow, adding NVMe drives without sacrificing GPU or network bandwidth becomes critical. The LRNV9347L-2I PCIe NVMe switch adapter solves this by expanding one PCIe 3.0 x8 slot into two high-speed SFF-8643 connections, enabling scalable storage for data-intensive applications.
Powered by the PLX PEX8747 controller, this adapter delivers a total PCIe transfer rate of up to 64Gb/s, with each SSD achieving up to 32Gb/s simultaneously. This non-blocking architecture ensures full line-rate performance on all ports, eliminating storage bottlenecks in high-resolution graphics and communication platforms while supporting peer-to-peer traffic and multicast.
Ideal for servers, storage systems, and graphics platforms requiring native NVMe driver support without additional software overhead. The LRNV9347L-2I offers reliable, plug-and-play expansion for RedHat, Windows, VMware, and other major operating systems, ensuring maximum bandwidth efficiency for enterprise workloads.
Non-blocking switch fabric delivers up to 64Gb/s total bandwidth with full line rate on all ports.
Expands one PCIe x8 slot to two internal SFF-8643 ports for connecting two NVMe SSDs simultaneously.
Based on PLX PEX8747 PCIe switch chip for reliable host-centric and point-to-point traffic management.
Requires no additional drivers; NVMe drives are presented natively to the host using standard OS drivers.
Supports eight traffic classes per port and Access Control Services for enhanced reliability and serviceability.
