About the HPE 817718-B21 - HPE Ethernet 10/25Gb 2-port 631SFP28 Adapter

For low-latency workloads, NIC offload capabilities directly translate to freed CPU cycles—and the HPE Ethernet 10/25Gb 2-port 631SFP28 Adapter (part number 817718-B21) delivers substantial throughput gains through its dual-port architecture and intelligent packet processing. This network adapter combines a Broadcom BCM57414 controller with 2 SFP28 ports capable of 10GbE or 25GbE per port via auto-negotiated speed selection, connected to the host system through a PCIe 3.0 x8 interface in a low-profile form factor. The 817718-B21 implements enterprise-grade offload features including TCP/UDP/IP checksum offload, Large Send Offload (LSO), Large Receive Offload (LRO), Receive Side Scaling (RSS), and VLAN tag insertion/stripping—each function designed to reduce CPU overhead in high-throughput environments. Support for jumbo frames up to 9KB MTU, IEEE 802.3x flow control, and IEEE 802.1Q VLAN tagging rounds out the feature set for demanding datacenter deployments.

Network engineers and infrastructure architects deploying HPE ProLiant Gen9, Gen10, or Synergy systems select this adapter when consolidating I/O bandwidth and eliminating CPU bottlenecks in virtualized or bare-metal environments. The 631SFP28 supports Single Root I/O Virtualization (SR-IOV), enabling efficient multi-tenant or workload isolation scenarios, while Wake on LAN capability supports flexible power management policies. HPE integration extends across management planes: iLO, iSUT, and the HPE Service Pack for ProLiant (SPP) all recognize and manage this adapter natively. Operating system support spans Windows Server 2012 R2 and later, RHEL, SLES, and VMware ESXi 6.0 and later, ensuring broad compatibility across heterogeneous environments. The adapter carries RoHS regulatory compliance, aligning with corporate sustainability requirements.

Whether you are standardizing on HPE networking hardware, upgrading fabric density, or architecting a high-performance compute cluster, the HPE 817718-B21 delivers proven reliability and integration.
