Multi-Host PCIe Switch Card

The LRNV9349-8I is a PCI Express x16 Gen 3 multi-host switch card built around the PLX 8749 chipset. It provides eight internal SFF-8643 connectors for attaching up to eight NVMe SSDs or PCIe adapter cards. The card delivers a data transfer rate of 6.0 Gbps and weighs 0.33 lb.

Suits multi-host storage clusters.

This card targets servers, storage arrays, communications gear and graphics platforms that need scalable, non-blocking interconnects between multiple hosts and endpoints. It is not intended for builders who only need a single NVMe drive on a desktop motherboard, nor for systems lacking a full x16 Gen 3 slot.

Occupies one x16 Gen 3 slot to fan out eight U.2

The adapter consumes a single PCIe 3.0 x16 lane and breaks it out to eight SFF-8643 ports, freeing additional expansion slots that would otherwise be needed for individual controllers. Its cut-through switching achieves 126 ns maximum latency with 2048-byte packet payloads, enabling full line-rate performance across all connected endpoints.

Perguntas sobre este artigo

Which motherboard slot is required for the LRNV9349-8I to operate at PCIe 3.0 x16?

The card needs a physical PCIe x16 slot wired for Gen 3.0 to deliver its full host-bus bandwidth.

Can the eight SFF-8643 ports drive NVMe SSDs while the rest of the system runs on PCIe 2.0 lanes?

Yes — the PLX 8749 switch negotiates per-port speed, so each NVMe SSD will run at the highest rate its own link supports.

How can I verify the adapter is delivering the 126 ns cut-through latency after installation?

Run a PCIe latency test tool that measures round-trip time across the switch; a result near 126 ns confirms the PLX 8749 is operating in cut-through mode.
