PCIe 3.0 x8 switch adapter expanding up to 4 internal M.2 NVMe SSDs for high-bandwidth storage.
Scaling storage capacity in a PCIe slot-limited server often means compromising between SSDs and GPUs. The LRNV9547LP-4I solves this by expanding a single PCIe x8 slot into four high-speed M.2 NVMe connections, ensuring your data center maintains maximum throughput without sacrificing expansion slots.
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 eliminates storage bottlenecks, enabling simultaneous high-performance access for AI training clusters or real-time analytics workloads.
Ideal for servers requiring dense, high-speed local storage, the LRNV9547LP-4I supports M.2 form factors 2242 through 22110. Its robust design ensures reliable peer-to-peer traffic handling, making it the optimal choice for enterprises needing scalable, low-latency NVMe storage expansion.
Expands one PCIe x8 slot to four M.2 NVMe SSDs with up to 64Gb/s total transfer rate.
Full line rate on all ports with peer-to-peer traffic support for maximum performance.
Supports M.2 2242, 2260, 2280, and 22110 form factors with PCIe Gen3 compliance.
Eight traffic classes per port ensure reliable data prioritization for critical applications.
