HPE 817737-B21 Ethernet 10Gb 2-Port 562T NIC Adapter
Overview
The HPE 817737-B21 is a high-performance dual-port 10GBASE-T network adapter designed for HPE ProLiant servers. This Ethernet adapter addresses the increasing demand for network bandwidth in virtualized data centers and cloud computing environments. It provides a reliable and low-latency solution for alleviating I/O bottlenecks in enterprise servers, ensuring that network infrastructure does not impede application performance. By offering a straightforward upgrade path from 1GbE, it allows IT teams to enhance server connectivity using existing and familiar CAT 6A twisted-pair cabling. Powered by the Intel X550 controller, the adapter optimizes server efficiency by offloading key network processes from the main CPU. Features such as TCP Segmentation Offload (TSO), and support for Tunnel Offloads like VXLAN and NVGRE, significantly reduce processor utilization, freeing up valuable cycles for core applications and virtual machines. This capability is critical in dense virtualization environments where CPU resources are at a premium, translating directly to improved workload performance and higher VM density per server. Designed as a stand-up PCIe 3.0 x4 card, the 562T adapter integrates seamlessly into a wide range of HPE ProLiant rack servers. Its dual RJ-45 port design supports network redundancy and load balancing for enhanced fault tolerance and uptime. Management is streamlined through HPE’s native toolsets, ensuring that the adapter is a validated, tested, and qualified component within the server ecosystem. This simplifies deployment and ongoing maintenance, providing a dependable connectivity solution for mission-critical applications.
