Product Description
The Dell R887V network adapter card, featuring the Mellanox ConnectX-4 controller, is engineered to deliver cutting-edge 25 Gigabit Ethernet performance for Dell server environments. This adapter boasts dual SFP+ ports, enabling high-speed, full-duplex communication at 25Gb/s per port, making it suitable for data-intensive applications, high-performance computing (HPC), and demanding enterprise workloads that require significant network throughput. The ConnectX-4 technology is renowned for its advanced capabilities, including support for RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE). RDMA allows network adapters to transfer data directly from the memory of one computer to the memory of another without involving the operating system, significantly reducing latency and CPU overhead. This feature is critical for applications such as storage networking, distributed databases, and real-time analytics where minimizing network latency is paramount. Installed via a PCIe Gen3 x8 interface, the R887V ensures ample bandwidth for the dual 25GbE ports. Its design as a Dell-specific component guarantees seamless integration with compatible Dell server chassis and systems, simplifying deployment and ensuring optimal performance. This network adapter is an excellent choice for organizations seeking to upgrade their server infrastructure to support next-generation networking speeds and advanced, low-latency communication protocols.
