HPE 642SFP28 10/25Gb Ethernet Adapter – Professional Dual-Port SFP28 Network Adapter for Enterprise Servers

The HPE Ethernet Adapter 10/25GB 2-port 642SFP28 is a dual-port server NIC engineered for data center environments running virtualization, high-density storage, and latency-sensitive workloads. By supporting both 10 and 25 Gbps speeds within a single adapter, it provides infrastructure flexibility without requiring separate hardware for each link speed, reducing rack complexity and cabling overhead.

The two SFP28 ports are compatible with optical transceivers and DAC/AOC cables, enabling seamless integration into spine-leaf and top-of-rack switching architectures. Hardware-based TCP/IP offloading, VLAN segmentation, and QoS support shift network processing off the host CPU, improving application throughput for virtualized workloads, real-time databases, and NVMe over Fabric storage deployments. Consistent low latency makes it suitable for HPC clusters and financial or analytics platforms with strict performance requirements.

The 642SFP28 integrates natively within the HPE ProLiant and HPE Synergy ecosystem, with full support through HPE iLO and server management toolsets. PCIe installation and broad hypervisor compatibility — VMware, Hyper-V, Linux KVM — allow rapid adoption in existing virtualized environments without disrupting the current network stack.

Recommended for datacenter infrastructure engineers and solution architects requiring a reliable 25GbE server adapter with low administrative overhead and native HPE platform integration. The optimal choice for upgrading server network connectivity within HPE environments while preserving existing switching infrastructure investments.
