HPE 665249-B21
Ethernet 10 Gb 2‑Port SFP⁺ Network Adapter – Model 665249‑B21 (560SFP⁺, Intel 82599)
The HPE 665249‑B21 Ethernet 10 Gb 2‑Port 560SFP⁺ Network Adapter (Intel 82599) is an enterprise-grade plug-in Network Adapter delivering dual 10 Gb SFP⁺ connectivity optimized for HPE ProLiant Gen8 and Gen9 servers. With feature-rich offloads and virtualization support, it’s ideal for high-throughput data centers, virtualization, and storage workloads.
Features
Powered by the Intel 82599 controller (branded X520‑DA2), this Network Adapter achieves up to 20 Gb/s bi-directional per port (40 Gb total) and integrates hardware support for advanced features—such as jumbo frames, VLAN tagging, TSO, RSS, MSI‑X, and IEEE 1588 precision timing—for scalable virtualization and efficient CPU utilization
Advanced Options
Designed as a low-profile, PCI Express 2.0 x8 card (compatible with x4 slots), it’s server-certified for a wide range of HPE ProLiant platforms, including DL20/360/380 Gen9, ML350 Gen9, Apollo Gen9, and others
