HPE 662243-b21

Dual‑Port 10 GbE SFP+Network Adapter (560FLR‑SFP+, PCIe 2.0 ×8)

The HPE 662243‑B21 (560FLR‑SFP+) is a dual‑port 10 Gigabit Ethernet FlexibleLOM adapter designed for HPE ProLiant Gen8 and later servers. Blu­tressed by the Intel 82599 (X520‑DA2) controller, it offers two SFP+ cages for either SR/LR fiber modules or DAC copper cables. With a compact FLR footprint for blade or rack servers, the adapter delivers consistent 10 Gbps performance per port, with support for virtualization, offload features, and a passthrough low latency design. Ideal for dense server deployments requiring high-throughput networking in a compact footprint.

Features

This FlexibleLOM card connects to the onboard PCIe 2.0 ×8 slot and supports line-rate 10 GbE on both ports across fiber or copper mediums. It features hardware acceleration such as SR‑IOV, RSS, MSI‑X, jumbo frames, TSO, checksum offload, PXE boot, Wake-on-LAN and NIC teaming. Certified on HPE Gen8/Gen9 server lines, including DL/ML/Apollo series, it integrates seamlessly into virtualization environments running VMware, Linux, or Windows. Low-power (~10 W) and thermal compliant with HPE Sea-of-Sensors architecture, it’s ideal for power- and space-constrained systems. ([turn0search1]turn0search12turn0search15)
