Product Description
The HP 870825-B21 is a dual-port 10/25 Gigabit Ethernet network adapter that utilizes SFP28 connectors, offering exceptional speed and bandwidth for modern data center environments. Equipped with the Broadcom BCM57416 controller, this adapter is engineered to meet the stringent demands of high-performance computing (HPC), storage networking, and virtualized environments where low latency and high throughput are critical. This adapter supports advanced features such as Remote Direct Memory Access (RDMA), which allows network adapters to transfer data directly from the memory of one computer to another without involving the operating system. This significantly reduces CPU overhead and latency, making it highly suitable for storage solutions like NVMe-oF and distributed applications that require rapid data access. The SFP28 interface provides flexibility, allowing for both 10Gb/s and 25Gb/s operation depending on the installed transceiver and network infrastructure. With its PCIe v3.0 x8 interface, the HP 870825-B21 ensures ample bandwidth to support its high-speed ports, preventing bottlenecks and maximizing network performance. It is an ideal choice for servers requiring robust and scalable network connectivity, enabling faster data processing, improved application responsiveness, and enhanced overall system efficiency in demanding enterprise and cloud deployments.
