Product Description
The HP 789125-001 is a high-performance network adapter designed to deliver 40 Gigabit Ethernet (40GbE) connectivity to servers and workstations. This adapter features a single QSFP+ (Quad Small Form-Factor Pluggable Plus) port, which is the standard connector for 40GbE connections, supporting high-speed data transmission over fiber optic or copper cabling. The QSFP+ interface allows for flexibility, as it can often be used with different types of transceivers or direct-attach cables to connect to switches or other network devices. This network adapter connects to the host system via a PCI Express (PCIe) interface. While the exact specification might vary, it typically utilizes a PCIe 3.0 x8 or x16 slot to ensure sufficient bandwidth for the 40Gbps data rate. This high-speed interface is crucial for preventing bottlenecks between the network adapter and the server's CPU and memory, especially in demanding environments like data centers, high-performance computing clusters, or large enterprise networks. The 789125-001 is built to handle high volumes of network traffic efficiently. It supports various networking protocols and features common in enterprise environments, potentially including features like TCP/IP offload, large send offload (LSO), and support for virtualization technologies such as SR-IOV. Its primary purpose is to provide robust and fast network connectivity for applications that require significant bandwidth, such as large file transfers, video streaming, storage area networks (SANs), and high-performance computing tasks.
