HPE 817720-B21 10Gb 2-Port 535FLR-T Network Adapter
Overview
The HPE 817720-B21 is an enterprise-grade, dual-port 10GBASE-T network adapter designed for HPE ProLiant Gen10 servers. Housed in a FlexibleLOM form factor, it provides a straightforward and cost-effective upgrade path from 1GbE to 10GbE speeds, addressing the growing need for higher network bandwidth in virtualized and converged data center environments. It solves network bottlenecks for I/O-intensive applications without requiring a complete overhaul of existing CAT 6A twisted-pair cabling infrastructure. This adapter leverages the Broadcom BCM57416 controller to deliver full 10GbE line-rate performance with low power consumption. It features advanced stateless offloads, such as Tunnel Offload for VXLAN and NVGRE, which process network virtualization overlays in hardware. This significantly reduces CPU overhead, freeing up processor cycles for critical application workloads and increasing virtual machine density, a tangible benefit in high-density server deployments. Designed for seamless integration, the 535FLR-T adapter occupies a dedicated FlexibleLOM slot on the server motherboard, preserving valuable standard PCIe slots for other expansion cards. Management is unified within the HPE ecosystem, utilizing tools like HPE Systems Insight Manager (SIM) and iLO for configuration and monitoring. Its backward compatibility with 1GBASE-T networks ensures a smooth, phased deployment, allowing organizations to upgrade their network infrastructure at their own pace.
