HPE 817753-B21 10/25Gb 2-Port 640SFP28 Network Adapter
Overview
The HPE 817753-B21 is a high-performance, dual-port 10/25GbE network adapter designed to address network bottlenecks in modern data centers. Engineered for select HPE ProLiant and Apollo servers, it provides a direct solution for environments struggling with increased traffic from virtualization, cloud workloads, and data-intensive applications. This adapter integrates a Mellanox ConnectX-4 Lx controller, enabling advanced hardware offloads that significantly boost efficiency. Key among these is RDMA over Converged Ethernet (RoCE), which bypasses the host TCP/IP stack to reduce latency and lower CPU utilization. This results in accelerated performance for applications like Microsoft SQL and Hyper-V Live Migration. Tunnel offloads for VXLAN and NVGRE further enhance performance in virtualized overlay networks. As a low-profile, plug-in PCIe 3.0 x8 card, this adapter offers straightforward integration into rack-mount server infrastructures. It is a fully validated and tested solution optimized for HPE server platforms, ensuring reliable operation and simplified network management through utilities that support SNMP, such as HPE Systems Insight Manager.
