Features

Built on the Next-Gen QLogic/Emulex single-chip 10Gb Ethernet architecture, the 530FLR-SFP+ adapter delivers exceptional throughput—up to 20 Gbps full-duplex per port, 40 Gbps aggregate—bridging high-performance requirements with modern virtualization needs. ([turn0search15]As a FlexibleLOM card, it installs directly into select HPEProLiant Gen8/Gen9 servers—such as DL360p, DL380p, SL250s—eliminating the need for PCIe slots and simplifying deployments. It supports advanced features like VLAN tagging (802.1Q), NIC teaming, Receive Side Scaling (RSS), Large Send/Receive Offload (LSO/TSO), tunnel offloads (VXLAN, NVGRE), and virtualization optimizations including SR-IOV, NPAR, VMware NetQueue, and Microsoft VMQ. ([turn0search15Thermal and power efficiency are enhanced viaHPE's Sea of Sensors 3D technology—which dynamically adjusts cooling—and power draw remains modest under typical load. Firmware integration ensures compatibility with HPE management tools like Systems Insight Manager and Intelligent Provisioning, so deployment, monitoring, and diagnostics are seamless.
