HPE 561FLR-T

Ethernet 2-Port 10 Gb Network Adapter (Refurbished)

The HPE 561FLR-T Ethernet 2-Port Adapter is a high-performance, refurbished FlexibleLOM (FLR) module offering dual 10 Gigabit Ethernet ports. Powered by the Intel Ethernet Controller X540, it's engineered for use in HPE ProLiant Gen8 and Gen9 servers, delivering line-rate performance with energy efficiency via CAT 6A cabling up to 100 meters and backward compatibility with Gigabit networks. Ideal for virtualized and cloud-centric infrastructures, this adapter supports advanced features like VLAN tagging, MSI-X, SR-IOV, Receive Side Scaling (RSS), jumbo frames, PXE boot, VMware NetQueue, Microsoft VMQ, TOE, and iSCSI offloading Its refurbished status offers a cost-effective yet robust connectivity solution for enterprise environments.

Features

Built around the Intel X540 controller and utilizing PCIe 2.1 x8 interface, the HPE 561FLR-T delivers impressive data throughput—up to 20 Gbps bi-directional per port, or 40 Gbps aggregate . Its RJ-45 10GBASE-T connectors support standard Ethernet cabling, allowing up to 100 m of CAT 6A or 30 m with CAT 6 Tailored for virtualized workloads, it provides hardware offloads—like TCP/UDP checksum, segmentation (TOE/TSO), iSCSI initiator offloading, and advanced virtualization (SR-IOV, VMDq, VMQ)—to reduce PCIe utilization and CPU overhead . FlexibleLOM design enables tool-free swapping in supported ProLiant servers without interrupting operations, delivering scalability with minimal maintenance impact 

Advanced Options

The HPE 561FLR-T adapter stands out for reliability and performance even as a refurbished component. It ensures stable 10 GbE connectivity with all ports running at full line rate. With a substantial suite of hardware offload capabilities, it minimizes host CPU burden—especially valuable in virtualized data centers or software-defined environments. Features like VMQ and NetQueue facilitate smoother traffic processing, optimizing multi-core CPU utilization
