HPE Ethernet 10/25Gb 2-port 621SFP28 Adapter (OCP 3.0)

The HPE Ethernet 10/25Gb 2-port 621SFP28 Adapter is a high-performance network interface card designed for HPE ProLiant Gen10 Plus and Gen11 server platforms. This OCP 3.0-compliant NIC delivers dual 10/25 Gigabit Ethernet ports using SFP28 transceiver connectivity, enabling flexible network configurations that scale from 10 Gbps to 25 Gbps per port based on transceiver selection and network infrastructure requirements.

The adapter integrates seamlessly into OCP 3.0 form factor slots on supported HPE server architectures, providing enterprise-grade reliability and performance for demanding workload consolidation scenarios. Its dual-port design reduces overall adapter footprint compared to single-port solutions while maintaining independent per-port flow control and advanced Ethernet features.

Typically deployed in high-density virtualization clusters, containerized compute environments, and enterprise data center refresh cycles, this adapter supports the evolving networking requirements of modern cloud and on-premises infrastructure at scale.

Ideal for

• VMware vSphere and KVM hypervisor deployments requiring high-throughput inter-VM and storage traffic isolation
• OpenStack and Kubernetes cluster networking for container orchestration and persistent storage access
• Database replication and real-time analytics workloads benefiting from low-latency, high-bandwidth interconnects
• High-frequency trading and financial services environments leveraging 25 Gbps capability for market data feeds
• Tiered storage systems and hybrid cloud architectures connecting to NVMe-over-Fabrics infrastructure
• Enterprise backup and disaster recovery systems requiring sustained multi-gigabit throughput over extended operations
