Lenovo X550-T2 10 Gb Dual-Port RJ-45 CNA PCI-E Adapter | Enterprise Ethernet

Deliver more bandwidth where copper still makes sense. The Lenovo X550-T2 dual-port CNA adapter brings 10 Gigabit Ethernet over RJ-45 to compatible PCI-E systems, giving infrastructure teams a direct path to higher throughput without reworking the cabling plant. Dual-port design helps balance performance and slot efficiency. In server environments, that means you can add two high-speed network connections from a single internal card, which is useful for uplinks, storage traffic, or separated production and management paths. RJ-45 connectivity also keeps deployment straightforward in data centers already standardized on copper. As a CNA-class adapter, this model is positioned for environments that want a more capable network interface than a basic NIC. It is a practical choice when bandwidth, port density, and internal expansion efficiency matter more than low-cost commodity hardware. For teams comparing options, the X550-T2 offers a focused combination of 10 Gb speed, dual-port flexibility, and enterprise-friendly copper connectivity.
