Shenzhen Lianrui Information Technology LRFC6911N 1 Port SFF-8643 to PCIe x16 Slot Adapter

Connection Interface

The LRFC6911N adapter bridges a single SFF-8643 Mini-SAS HD receptacle to a physical PCIe x16 slot operating at x4 bandwidth. It is designed for system integrators who need to extend a PCIe link from a host adapter or switch card to a standard expansion slot in servers or specialised chassis.

Target Builder

This card suits engineers adding GPUs, network controllers or capture cards to platforms that expose only SFF-8643 uplinks. Builders whose host provides native PCIe slots, U.2 bays or M.2 connectors should look elsewhere because the adapter adds latency and requires a compatible upstream switch or HBA.

Sustained Operation

A 15-pin SATA power socket feeds the slot directly, delivering auxiliary current for devices that draw more than the bus supplies. The x4 electrical link caps throughput at four lanes, so high-bandwidth accelerators will plateau at that ceiling during prolonged compute or storage workloads.
