Detailed Specifications

HPE 817750-B21 640FLR-SFP28 2-Port 10/25GbE Adapter

Overview

The HPE 817750-B21 is a dual-port 10/25GbE network adapter in a FlexibleLOM form factor, engineered for high-throughput, low-latency connectivity in modern data centers. Designed specifically for select HPE ProLiant servers, it addresses network bottlenecks in virtualization, cloud computing, and storage-intensive application environments. This adapter provides a direct, high-speed interface to handle the escalating demands of complex workloads. At its core, this adapter utilizes RDMA over Converged Ethernet (RoCE) to bypass the host CPU's TCP/IP stack. This significantly reduces latency and frees up processor cycles for critical application tasks. By offloading packet processing, it accelerates performance for Microsoft Hyper-V Live Migration, SQL databases, and SMB Direct storage access, resulting in greater server efficiency and faster data transfers. The FlexibleLOM (FLR) form factor allows for seamless integration without consuming a standard PCIe slot, preserving expansion options for other components. Management is streamlined through HPE's native toolsets, including HPE Systems Insight Manager (SIM), which provides administrators with a unified view of server and network adapter health for simplified lifecycle management.

Key Features

  • Dual 10/25GbE ports for up to 100Gb/s total throughput.
  • RDMA over Converged Ethernet (RoCE) for lower latency.
  • Tunnel offload support for VXLAN and NVGRE deployments.
  • Supports UEFI, legacy boot options, and PXE network boot.
  • Auto-negotiates to 10GbE for backward compatibility.
