Sustain critical workloads with a dual-port 10GbE adapter built for servers that need more bandwidth without moving to fiber. The AddOn 49Y7970-AO pairs Intel X540 silicon with two open RJ-45 ports, giving infrastructure teams a practical path to higher throughput on familiar copper infrastructure. PCI Express 2.0 x8 provides the lane width needed to support sustained network traffic, while the dual-port design helps separate application, storage, or virtualization traffic across links. That matters in environments where congestion, backup windows, and east-west traffic can expose weaker adapters fast. This model is a strong fit for teams standardizing on copper 10 Gigabit Ethernet and looking for a server adapter that aligns with enterprise deployment patterns. The lifetime warranty adds long-term confidence for platforms expected to stay in service for years, not quarters.
