Dual-Port 40 Gb QSFP+ Card

The QLogic QL45412HLCU-CK is a dual-port network interface card delivering 40 Gb connectivity through QSFP+ cages. It plugs into a PCIe slot to add two high-speed Ethernet links for servers or workstations needing extra bandwidth. The card targets administrators upgrading rack-mount systems or dense compute nodes.

Low-Profile PCIe Build

A low-profile bracket fits 1U and 2U chassis without blocking adjacent slots. Dual QSFP+ cages accept direct-attach copper or optical transceivers for flexible reach. The PCIe Gen 3 x8 edge connector supplies the throughput both ports require. Buyers needing more than two ports or a different cage format should select another model.
