LENOVO 42D3702 – HCA 400Ex-D, x8 PCI-Exp. dual 4X DDR IB port,

Detailed Description:

The LENOVO 42D3702 – HCA 400Ex-D is a high-performance Host Channel Adapter designed to facilitate high-speed data transfers within InfiniBand (IB) networks, making it a vital component for data centers and high-performance computing environments. This adapter employs dual 4X Data Rate (DDR) IB ports, each capable of providing data transfer rates significantly higher than those achievable with standard networking protocols. Its incorporation of an x8 PCI Express interface ensures compatibility with a broad range of server systems and provides a robust, high-speed connection to the host system. The high bandwidth and low latency characteristics of this HBA make it particularly well-suited for tasks that demand rapid data communication, such as clustered computing, data streaming, and complex scientific computations. The adapter’s support for advanced InfiniBand architecture features, including RDMA (Remote Direct Memory Access), enhances its efficiency, allowing direct memory access between host and target devices without burdening the CPU. As a result, the LENOVO 42D3702 – HCA 400Ex-D significantly boosts performance and scalability in networked systems, enabling more efficient processing and management of large volumes of data.
