HPE655639-B21

(560FLB) Dual-Port 10 Gb Gigabit Ethernet Adapter- Refurbished

The HPE655639-B21 (560FLB) Gigabit Ethernet Adapter is a high-performance, dual-port 10 GbE FlexibleLOM card designed for HPEBladeSystem c-Class Gen8/Gen9 servers. Based on the reliable Intel 82599 chipset, this adapter delivers full duplex 10 Gbps per port (up to 40 Gbps aggregate) and supports virtualization offloads and advanced networking features. This refurbished model is ideal for enhancing server connectivity in virtualization hosts, HPC clusters, and enterprise blade deployments, offering exceptional throughput and reliability at a cost-effective price.

Features

This FlexibleLOM adapter integrates seamlessly into compatible server chassis, delivering enterprise-grade networking without occupying traditional PCIe slots. It boasts full-duplex throughput of 20 Gb/s per port (40 Gb/s aggregate), supporting jumbo frames (up to 9 KB MTU), VLAN tagging, NIC teaming, RSS, MSI-X, PXE boot, and Wake-on-LAN on Port 1. Although iSCSI acceleration isn't supported, this card excels in virtualized environments via support for VMware NetQueue, Microsoft VMQ, and Intel VMDq. Built for blade servers, it helps reduce CPU utilization, minimize latency, and support high-density workloads.

Advanced Options

Built for continuous operation within blade server environments, this adapter is engineered for ultra-low latency and high fault tolerance. The Intel 82599 foundation ensures consistent throughput and robust compatibility. Offloading capabilities such as TCP/IP checksum,
