High-performance PCIe switch adapter connecting 8 NVMe U.2 SSDs via SFF-8643.
Scaling storage capacity in high-performance servers often creates bottlenecks when limited PCIe lanes restrict NVMe drive connectivity. The LRNV9349-8I solves this by expanding a single PCIe x16 slot into eight independent U.2 NVMe connections, ensuring maximum throughput for data-intensive applications without sacrificing GPU or network expansion slots.
Built on the Broadcom PEX 8749 controller, this adapter delivers a maximum latency of just 126ns and supports packet payloads up to 2048 bytes. With eight internal SFF-8643 connectors, it enables full line-rate performance on all ports, allowing processors to focus on computational tasks while the integrated DMA engine handles data movement efficiently.
Ideal for AI training clusters, cloud computing nodes, and enterprise storage arrays, the LRNV9349-8I ensures reliable connectivity for up to 8 NVMe SSDs. Its robust design supports major operating systems including Windows, Linux, and VMware, providing a scalable storage solution for modern data centers requiring high IOPS and low latency.
Powered by the versatile PEX 8749 switch controller for reliable PCIe expansion.
