HPE665249-B21
Ethernet 10 Gb 2-Port SFP⁺ Network Adapter- Model 665249-B21 (560SFP⁺, Intel 82599)
The HPE665249-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 Adapterachieves 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
Product Key Features
10 Gb SFP⁺ ports with Intel 82599 (X520-DA2) chipset
PCIe Gen2 x8 (backward compatible with x4) low-profile bracket included
Supports SR-IOV, RSS, MSI-X, jumbo frames, DPDK for virtualization acceleration
Hardware offloads: TCP/UDP checksum, VLAN tagging, TSO/LRO, IEEE 1588 PTP
Auto-negotiates 1 Gb/10 Gb on both ports; PXE boot and LLDP support
Optimized for HPE ProLiant Gen8/Gen9 servers including DL/DL360/DL380/Apollo series
Reliability & Performance
