Quad-port PCIe 3.0 x16 to M.2 NVMe switch adapter for high-bandwidth storage expansion.
Scaling storage capacity in a PCIe slot-limited server often means compromising between SSDs and GPUs. The LRNV9547-4I solves this by expanding one PCIe x16 slot into four independent M.2 NVMe connections, ensuring maximum bandwidth for data-intensive applications.
Powered by the PLX PEX8747 controller, this adapter delivers a total PCIe transfer rate of up to 128Gb/s, with each SSD achieving up to 32Gb/s. This non-blocking architecture eliminates storage bottlenecks, enabling simultaneous high-speed access for all four drives without performance degradation.
Ideal for servers, storage systems, and graphics platforms requiring high-resolution data handling, the LRNV9547-4I supports M.2 form factors 2242, 2260, 2280, and 22110. Its robust design ensures reliable peer-to-peer traffic management, making it a critical component for scalable enterprise storage solutions.
Non-blocking switch fabric provides full line rate on all ports with up to 128Gb/s total PCIe transfer rate.
Connects four M.2 NVMe SSDs (2242/2260/2280/22110) via a single PCIe x16 slot.
Powered by Broadcom PLX PEX8747 for reliable peer-to-peer traffic and multicast support.
Supports eight traffic classes per port for optimized data flow management.
