Expand storage with 4 internal NVMe SSDs via PCIe 3.0 x8 switch.
When server PCIe slots are limited, expanding high-speed NVMe storage without sacrificing GPU or network bandwidth becomes a critical challenge. The LRNV9347L-4I PCIe NVMe Switch Adapter solves this by converting a single PCIe 3.0 x8 slot into four independent SFF-8643 ports, enabling scalable storage expansion for data centers and graphics platforms.
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 architecture ensures full line-rate performance on all ports simultaneously, eliminating storage bottlenecks in high-throughput applications like AI training clusters and real-time analytics.
Ideal for servers requiring dense NVMe storage, the LRNV9347L-4I supports native NVMe drivers across Windows, Linux, and VMware environments without additional software. Its robust design includes QoS with eight traffic classes per port, ensuring reliable, low-latency data access for mission-critical enterprise workloads.
Expands one PCIe 3.0 x8 slot to four SFF-8643 ports for NVMe SSDs.
Features PLX PEX8747 switch chip for non-blocking, full line-rate performance.
Requires no additional drivers; uses native OS NVMe drivers for seamless integration.
Supports eight traffic classes per port and Access Control Services for stable operation.
