PCIe 3.0 x4 to dual USB 3.1 Gen2 adapter with Type-A and Type-C ports, up to 10Gbps.
When internal I/O slots are exhausted in compact server chassis, expanding connectivity without sacrificing performance becomes critical. The LRSU9A42-AC addresses this by bridging PCIe interfaces to two high-speed USB 3.1 ports, enabling seamless integration of external storage arrays or peripherals in space-constrained environments.
This card features an ASM1142 controller delivering up to 10Gbps bandwidth per port via USB 3.1 Gen2 standards. With a skinny form factor fitting 2U/3U cases and support for hot-plugging, it ensures reliable data transfer rates while maintaining system stability under heavy loads.
Designed for Windows Server, Linux RHEL/CentOS, and Ubuntu environments, the LRSU9A42-AC offers robust driver support for enterprise deployments. Its backward compatibility with USB 2.0/3.0 ensures broad device interoperability, making it a versatile solution for data center expansion and industrial automation setups.
Up to 10Gbps bandwidth with USB 3.1 Gen2 support for rapid data movement.
Combines USB Type-A and Type-C ports for versatile peripheral connections.
Skinny design fits 2U/3U server racks without obstructing airflow.
Backward compatible with USB 2.0/3.0 and PCIe 2.0/3.0 slots.
