Detailed Specifications

HPE 665243-B21 

Ethernet 10 Gb 2‑Port 560FLR‑SFP+ FlexibleLOM Network Adapter

The HPE 665243‑B21 is a dual‑port 10 Gigabit Ethernet FlexibleLOM adapter offering two SFP+ optical or DAC copper ports. Powered by the Intel 82599 controller, it connects via PCIe 2.0 ×8 in ProLiant Gen8/Gen9 rack servers. Delivering full line-rate 10 Gbps per port, this compact low‑power card is ideal for virtualization, server uplinks, and high‑throughput workloads. Its FLR design optimizes space and energy efficiency in dense data center deployments.

Features

Designed specifically for HPE ProLiant Gen8–Gen9 rack and scale‑out servers, the 560FLR‑SFP+ provides near 40 Gb/s aggregate bi‑directional bandwidthturn0search12turn0search4turn0search6. It supports both Direct Attach Copper (DAC) and SR/LR SFP+modules via optical cages. Key virtualization features include SR‑IOV, VMware NetQueue, Microsoft VMQ, RSS, MSI‑X, jumbo frames up to 9 KB, TSO/LSO, checksum offloads, VLAN tagging, LACP teaming, PXE boot, and Wake‑on‑LAN. Its design aligns with HPE Sea of Sensors for optimized thermal and power performanceturn0search4turn0search2.

Advanced Options

Built on the Intel 82599 chipset, the 665243‑B21 delivers enterprise-grade network throughput with minimal latency. Its hardware offloads minimize CPU usage in virtualized and storage-heavy environments, while jumbo frames and link aggregation improve

Product Key Features
