HPE 647581-B21

Gigabit Ethernet Adapter 10 Gb 2-Port 530FLR-SFP+

The HPE 647581-B21, also known as the 530FLR-SFP+, delivers high-speed, dual-port 10 Gb Ethernet connectivity in a FlexibleLOM form factor, ideal for HPE ProLiant Gen8 servers. Utilizing the Broadcom BCM57810S chipset, this adapter provides up to 20 Gb full-duplex per port (40 Gb aggregate) to support demanding workloads. Engineered for virtualization and performance-intensive applications, it includes enterprise-grade features like VLAN tagging, jumbo frames, NIC teaming, Receive Side Scaling (RSS), MSI-X, tunnel offloads (VXLAN, NVGRE), and both Windows VMQ and VMware NetQueue support. The compact, server-integrated design delivers robust performance at a great value in its refurbished form.

Features

This adapter is built on the Broadcom BCM57810S, featuring 256 MB of onboard memory, and plugs directly into the FlexibleLOM slot of HPE ProLiant Gen8 rack servers—including DL360p, DL380p, DL560, SL250s, and ML-series—freeing up PCIe slots It delivers reliable 40 Gbps aggregate throughput, ensuring low-latency and high-bandwidth performance for server clusters and virtualized environments.Advanced offloads such as TCP/IP checksum, VLAN support, jumbo frames, and hardware virtualization features like SR-IOV and NPAR help reduce CPU overhead and improve efficiency in multi-tenant or NFV setups 

Advanced Options

Other optimizations include PXE boot, NetQueue, and VMQ. HPE Sea of Sensors 3D technology dynamically controls cooling for efficiency and reduced noise Full integration with HPE management tools—like Intelligent Provisioning and Systems Insight Manager—ensures easy deployment and health monitoring.Refurbished units offer strong value, typically including a 90-day warranty and vendor testing to ensure performance and compatibility
