Sustain demanding east-west traffic, storage replication, and high-speed uplinks with dual 100 GbE QSFP28 connectivity on a PCIe 4.0 x16 host interface. The PCIE4-2QSFP28-AX is designed for environments where port density and throughput matter more than commodity adapter pricing. For modern virtualization clusters, analytics nodes, and high-performance server fabrics, this adapter gives you the bandwidth headroom to keep critical workloads moving without forcing a redesign of the network edge. Dual ports help separate traffic paths, simplify aggregation, and support resilient topologies in rack-scale deployments. Axiom positions this card for buyers who need enterprise-class connectivity in a form factor that fits standard PCIe server infrastructure. It is a practical choice when you are refreshing older 10/25 GbE links, building out storage networks, or standardizing on 100 GbE uplinks for compute-heavy environments. When the cost of congestion is measured in delayed jobs and underused hardware, a dual-port 100 GbE adapter becomes a direct infrastructure investment rather than a line item.
