817745-B21 – HPE Ethernet 10Gb 2-port 562FLR-T

Overview on the HPE 562FLR-T Adapter

The HPE Ethernet 10Gb 2-Port 562FLR-T Adapter (HPE Option Part Number: 817745-B21) is an enterprise-class, high-density network interface solution. It is engineered beautifully to maximize rack-mount communication speeds, minimize host CPU overhead, and streamline device virtualization layouts. Unlike standard stand-up PCIe cards, this card uses HPE’s specialized FlexibleLOM (Lan on Motherboard) form factor architecture. This customized structure plugs directly into the server’s dedicated LOM slot on the motherboard. Consequently, it saves your standard PCIe expansion channels for secondary graphic accelerators, extra raid arrays, or NVMe drive controller upgrades. Outfitted with dual 10GBASE-T RJ-45 copper terminals, it deploys easily using standard copper Category 6A twisted-pair network cables up to 100 meters. Therefore, it is designed perfectly for high-performance virtualized nodes, software-defined storage setups, and cloud computing environments.

This high-speed converged network card prioritizes physical system efficiency and processing offload routines. At its silicone heart, it features the industry-proven Intel® Ethernet Controller X550-AT2 processor chip. This intelligent processor implements full hardware-level acceleration for stateless TCP/IP stack offloads, large segment transfers, and payload checksums. By taking over these network verification computations natively, the card prevents processing jams on the server’s main host CPU. Each port drives a raw 10Gb/s line rate, creating up to 40 Gb/s of bi-directional theoretical aggregate bandwidth. This heavy-duty bandwidth pool ensures smooth local file migrations and eliminates bottlenecks during intensive data center operations.

Key Features & Performance

• Dual-Port 10GBASE-T Density: Features two high-bandwidth RJ-45 copper interfaces supporting 10Gbps line speeds over standard network cables. It supports auto-negotiation, making it fully backward compatible with 1Gbps copper networks.

• Intel X550 Core Chipset: Powered by a single-chip Intel X550-AT2 network processor. This architecture handles intense data traffic queues smoothly while keeping hardware power draw to a low 10.5 Watts.

• Advanced Tunnel Network Offloading: Fully supports VXLAN and NVGRE network virtualization overlay tunnels. This offloading logic allows cloud multi-tenant infrastructures to scale efficiently without triggering latency spikes.

• HPE Sea of Sensors 3D Framework: Integrates with HPE’s internal motherboard network of 32 autonomous thermal sensors. The system tracks temperature levels instantly, letting server fans ramp up only where cooling is needed to optimize energy efficiency.

• Full Wake-on-LAN (WoL) Support: Unlike standard stand-up cards, the 562FLR-T offers full Wake-on-LAN support through the PCIe bus on Port 1. This enables administrators to audit, patch, and boot down devices remotely during scheduled maintenance windows.

Virtualization Readiness & Data Security

The HPE 562FLR-T adapter hardens virtual machine setups by embedding traffic sorting and firmware validation defenses directly onto its circuit board:

• Near-Metal SR-IOV Acceleration: Features native Single-Root I/O Virtualization (SR-IOV) hardware lines. This mechanism bypasses host hypervisor software layers entirely, creating isolated virtual paths that lower latency and boost virtual network security.

• Data Plane Development Kit (DPDK): Optimized for high-speed DPDK packet processing libraries. This design accelerates database requests and satisfies the strict timing demands of telecommunications and e-commerce infrastructure.

• HPE Secure Boot Firmware Protections: Implements advanced Firmware Root of Trust verification checks alongside digital audit logs. This validation sequence blocks unauthorized or compromised boot-code execution attempts, protecting the host system right at initialization.

Conclusion

The HPE Ethernet 10Gb 2-Port 562FLR-T FlexibleLOM Adapter remains a premier, space-saving choice for optimizing high-speed data paths in enterprise racks. It successfully bridges the gap between older, bandwidth-choked Gigabit ports and ultra-fast 10Gb data lines using familiar, cost-effective RJ-45 copper wiring infrastructures. Specifically, this specialized card pairs a reliable Intel X550 controller core with hardware-driven SR-IOV pathways, advanced tunnel network offloads, and robust firmware protections. This technical configuration ensures your host operating system manages massive data migrations and large virtual machines with complete stability. Furthermore, its FlexibleLOM form factor and integration with HPE Sea of Sensors 3D technology ensure it runs with maximum efficiency inside server cabinets. It provides a balanced, secure, and cost-effective way to manage your enterprise networking workloads.
