Move more traffic through a single server with the AddOn dual-port 10 Gb SFP+ PCIe x8 network interface card. Built for fiber-based Ethernet connectivity, it gives infrastructure teams a straightforward way to expand bandwidth for virtualization hosts, backup systems, and clustered workloads. The dual-port design matters when one link is not enough. It allows you to separate production and replication traffic, build redundancy into the network path, or simply increase aggregate throughput for busy servers. With SFP+ connectivity, the card fits environments that already standardize on optical uplinks and want a compact adapter that slots cleanly into PCIe expansion. This is the kind of upgrade that earns its place in a production rack: not because it adds features you may never use, but because it solves a real bottleneck. Compared with lower-speed adapters, a 10 Gb dual-port card gives you more headroom for growth, fewer contention points, and a better match for modern server workloads that move large volumes of data all day.
