PCIe 3.0 x16 switch adapter expanding storage with four M.2 NVMe SSD slots.
Scaling storage capacity in PCIe slot-limited servers often requires compromising between SSD density and GPU availability. The LRNV9547L-4I PCIe NVMe switch adapter resolves this by expanding one PCIe x16 slot into four M.2 NVMe connections, enabling high-density storage without sacrificing expansion slots for other critical components.
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. This non-blocking switch fabric ensures full line-rate performance on all ports simultaneously, eliminating storage bottlenecks in data-intensive environments like AI training clusters and high-performance computing nodes.
Ideal for servers, storage systems, and graphics platforms requiring peer-to-peer traffic support, the LRNV9547L-4I supports M.2 SSDs in 2242, 2260, and 2280 form factors. Its robust design includes Quality of Service with eight traffic classes per port, ensuring reliable, high-bandwidth interconnectivity for demanding enterprise applications.
