Description
The HP FlexFabric 10Gb 2-port 526FLR-SFP+ Network Adapter (629138-B21) is a versatile and high-performance networking solution designed to meet the demands of modern data centers. It provides two 10Gb/s Ethernet ports, enabling high-speed connectivity for servers and workstations. The adapter leverages the PCIe 2.0 interface, offering ample bandwidth for demanding network traffic and applications. This adapter is engineered with advanced features to enhance network efficiency and reduce latency. It supports Single-Root I/O Virtualization (SR-IOV), which allows for direct assignment of network resources to virtual machines, thereby improving performance and reducing overhead. Additionally, the adapter includes support for RDMA over Converged Ethernet (RoCE), enabling low-latency, high-throughput data transfers essential for high-performance computing and storage applications. The 526FLR-SFP+ adapter also incorporates stateless offload capabilities for TCP, UDP, and IP protocols. This offloading reduces the burden on the server's CPU, freeing up processing power for applications. Its low-profile form factor makes it suitable for installation in a wide range of server chassis, including blade servers and standard rack servers, ensuring broad compatibility and deployment flexibility.
