The Hewlett Packard Enterprise 665249-B21 Ethernet 10Gb 2-Port 560SFP+ Adapter is a PCIe 2.0 x8 plug-in network card that adds two 10 Gigabit Ethernet SFP+ ports to HPE ProLiant Gen8 servers, enabling high-bandwidth, low-latency fiber connectivity in data centers. Built around the Intel 82599 controller, it supports 10 Gb/s Ethernet over SFP+ (fiber) with a two-port configuration that supports dense uplinks and inter-server links for virtualization, cloud environments, and data-intensive workloads. The card fits both full-height and low-profile server chassis, accommodating flexible rack deployments, and its part numbers include 665249-B21, 669279-001, and 665247-001. This adapter is commonly used in enterprise IT infrastructures requiring reliable 10 Gb networking, making it suitable for upgrades, expansions, or replacements of existing network interface cards. Common replacements include the HPE 530SFP+ 10Gb 2-Port Adapter, the HPE 560FLB 10Gb 2-Port FlexibleLOM Adapter, and the HPE 562SFP+ 10Gb 2-Port Adapter, offering familiar upgrade paths within the HPE 560SFP+/SFP+ family.
