The Broadcom NetXtreme E-Series Quad-Port 25Gb OCP 3.0 Ethernet Adapter is a high-performance network interface card (NIC) designed for servers, workstations, and data centers that need to handle high-bandwidth, low-latency networking. It supports 25Gb Ethernet (25G) speeds, which are essential for environments requiring high data throughput, such as in cloud computing, high-performance computing (HPC), and virtualized data centers.

The OCP 3.0 (Open Compute Project) specification refers to a standardized form factor for network cards and other components used in servers. The adapter typically features four 25GbE ports, enabling high-speed, multi-port network connectivity.

The Windows driver for this adapter enables the operating system to communicate with the NIC, allowing it to be used for networking tasks such as data transfer, internet connectivity, and server communication.
