When server workloads outgrow Gigabit, this Axiom dual-port RJ45 NIC gives infrastructure teams a direct path to 10 GbE over copper. The PCI Express 2.0 x8 interface provides the lane capacity needed for higher-throughput networking, while the dual-port design supports segmentation, redundancy, or parallel traffic flows. Because it uses RJ45, the card fits into existing twisted-pair Ethernet environments without requiring a fiber transition. That matters in mixed infrastructure where cabling standards, switch ports, and operational familiarity all influence deployment cost. For IBM server platforms, the 49Y7970-AX offers a practical upgrade path for virtualization hosts, storage-connected systems, and application servers that need more bandwidth headroom. Axiom pairs the hardware with a 3-year limited warranty, giving procurement teams a clearer ownership horizon for enterprise refresh cycles. It is a focused choice for teams that want 10 GbE performance in a copper-based form factor that stays compatible with established server designs.
