Keep critical workloads moving with a dual-port 10 Gb SFP+ network interface designed for IBM 49Y7980-compatible environments. This AddOn adapter gives infrastructure teams a practical path to high-bandwidth server connectivity without locking the deployment to a fixed transceiver choice. The open SFP+ design supports the optics strategy already in place, whether the link calls for short-reach or longer-reach fiber modules. Built on a PCIe x8 host interface, the card is suited for server expansion slots where sustained throughput and predictable performance are required. Dual ports make it easier to segment traffic, add redundancy, or dedicate bandwidth to storage, virtualization, or application tiers. For teams refreshing legacy hardware or standardizing spare parts, a comparable adapter can reduce procurement friction while preserving the network architecture already approved. When the cost of downtime is higher than the cost of the card, the value is in fit, speed, and deployment confidence. This model is aimed at environments that need a straightforward 10 GbE upgrade path with the flexibility to choose the right SFP+ optics for the job.
