The HPE 817749-B21 Ethernet 10/25Gb 2-Port 640FLR-SFP28 Adapter delivers high-speed network connectivity for HPE ProLiant Gen9 and Gen10 servers. It supports flexible bandwidth options and improves data throughput in modern data centers. This adapter fits the FlexibleLOM slot, maintaining clean cabling and space efficiency.
Each port supports 10Gb and 25Gb Ethernet speeds. So, users can scale performance based on network growth. The adapter delivers low latency and strong throughput for demanding workloads. It suits cloud, virtualization and storage applications that require fast data transfer.
The adapter supports RDMA over Converged Ethernet (RoCE). This feature reduces CPU load and improves network efficiency. It also supports VXLAN and NVGRE overlays. Therefore, it works well in software-defined networking environments.
HPE integrates secure firmware to protect against unauthorized modifications. The adapter also uses hardware offload features to improve packet handling. Because of this, workloads run smoother and more securely.
The 640FLR-SFP28 adapter works with selected Gen9 and Gen10 ProLiant servers. It installs easily in the FlexibleLOM slot without taking PCIe space. So, users keep expansion slots open for other needs.
The adapter helps reduce power consumption in dense rack setups. HPE Intelligent Management Tools simplify configuration, monitoring and firmware updates. IT teams save time and maintain strong uptime.
