Keep server I/O from becoming the bottleneck. The HPE BCM 57504 10/25GbE 4-port SFP28 OCP3 adapter is built for environments that need more bandwidth per slot without adding unnecessary complexity. With four SFP28 ports, it supports high-density fiber connectivity for modern data center fabrics, virtualization clusters, and storage-heavy workloads where predictable throughput matters. Its OCP3 design fits current HPE server architectures and helps preserve PCIe resources for other expansion needs. That matters when you are standardizing fleets, scaling rack density, or building around a network design that depends on compact, serviceable adapters rather than oversized add-in cards. The Broadcom foundation gives this model the credibility expected in enterprise deployments where adapter stability and interoperability are part of the purchase decision. Compared with lower-port-count alternatives, this adapter is aimed at teams that want fewer cards, fewer cables, and more aggregate bandwidth per server. It is a practical choice for infrastructure that must support multiple high-speed links without compromising airflow, service access, or rack efficiency.
