HPE 840138-001 562FLR-T 10GbE 2-Port Network Adapter
Overview
The HPE 840138-001 is an enterprise-grade, dual-port 10GBASE-T network adapter designed for seamless integration into HPE ProLiant Gen10 servers. As a FlexibleLOM (FLOM) module, it provides a dedicated, high-speed network interface without consuming a standard PCIe slot, making it ideal for dense data center environments where I/O expansion is critical. This adapter solves the network bottleneck problem for virtualization, cloud computing, and I/O-intensive server workloads by delivering up to 40 Gbps of bi-directional Ethernet bandwidth. Powered by the Intel X550 controller, this adapter delivers advanced performance features that optimize server efficiency. It utilizes tunnel offloads (VXLAN & NVGRE) to reduce CPU utilization in virtualized environments, allowing the processor to focus on application performance rather than network traffic management. Features like Single Root I/O Virtualization (SR-IOV) further enhance virtual network performance while decreasing CPU overhead, leading to tangible improvements in application responsiveness and virtual machine density. The 562FLR-T adapter is engineered for placement in compatible ProLiant Gen10 rack and tower servers, occupying the dedicated FlexibleLOM slot on the motherboard. Its plug-in card design simplifies installation and upgrades. Management is integrated within the standard HPE server ecosystem, supporting features like Pre-Boot Execution Environment (PXE) for remote boot and Wake-on-LAN (WOL) for power management, ensuring streamlined operations within existing infrastructure.
