QNAP Systems QXG-5G2T-111C - 2-port 5 gigabit Ethernet network expansion card

The QNAP QXG-5G2T-111C is a dual-port 5GbE network expansion card that adds two Ethernet interfaces to compatible systems, increasing total bandwidth. It is intended to accelerate large file transfers and backup operations. The card provides faster throughput than standard 1GbE connections, allowing systems to handle more simultaneous client requests. Performance gains are most noticeable when the network infrastructure also supports multi-gigabit speeds.

The card connects to the host system via a PCI Express slot and uses standard connectors for storage or server applications. Automatic speed negotiation allows the device to communicate with older networking hardware, enabling gradual infrastructure upgrades rather than requiring an immediate replacement of all switches. The two ports can be used to segregate traffic, for example, by keeping management data separate from storage traffic. The card is designed for compatible QNAP platforms with an available internal expansion slot.
