About the HPE 817753-B21 - HPE Ethernet 10/25Gb 2-port 640SFP28 Adapter

HPE Ethernet 10/25Gb 2-port 640SFP28 Adapter delivers high-speed connectivity via PCIe 3.0 x8 host interface, engineered for enterprise data centers requiring flexible 10GbE and 25GbE network throughput. Built on the Cavium FastLinQ 41000 Series network controller, this dual-port SFP28 adapter (part number 817753-B21) combines performance offload capabilities with intelligent traffic management, making it ideal for network engineers and infrastructure architects deploying next-generation server deployments.

The HPE 817753-B21 arrives in a low-profile, half-height form factor with a standard low-profile bracket included, enabling seamless installation in space-constrained rack environments. Advanced offload features—including LSO, LRO, RSS, VLAN tag insertion/stripping, and checksum offload—reduce CPU overhead while maintaining wire-speed performance. The adapter supports both SFP28 DAC cables and SFP28 optical transceivers, offering flexibility in network topology design. Full integration with HPE iLO and HPE OneView simplifies lifecycle management and monitoring across your infrastructure. Operating system support spans Windows Server 2012 R2 and later, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi, ensuring broad deployment compatibility.

Platform Compatibility and Deployment Scenarios

  • HPE ProLiant Gen9 and Gen10 rack and tower servers—validated performance and driver support
  • Dual 25GbE connectivity for storage-intensive workloads requiring high-bandwidth uplinks
  • Mixed 10GbE/25GbE environments where adaptive port speed negotiation simplifies multi-speed networks
  • Virtual machine host deployment with RSS for improved multi-queue performance and guest isolation
  • Data center fabric migration paths supporting both legacy 10GbE infrastructure and modern 25GbE networks
