Product Description
The IBM CX555A, powered by NVIDIA's ConnectX-5 technology, is a high-performance Host Channel Adapter (HCA) designed to deliver cutting-edge networking capabilities for demanding server environments. Featuring Virtual Protocol Interconnect (VPI), this adapter supports both InfiniBand Enhanced Data Rate (EDR) and 100 Gigabit Ethernet, offering unparalleled flexibility and performance. The single QSFP28 port allows for a direct, high-bandwidth connection to network switches or other servers, making it ideal for clustered computing, high-frequency trading, and large-scale data analytics. With its PCIe Gen3 x16 interface, the ConnectX-5 EDR VPI adapter ensures maximum data transfer rates between the host system's memory and the network. This is crucial for applications that are sensitive to latency and require high throughput, such as High-Performance Computing (HPC) clusters, Artificial Intelligence (AI) and Machine Learning (ML) training workloads, and high-performance storage solutions. The adapter's architecture is optimized to offload network processing tasks from the host CPU, freeing up valuable computational resources for application execution. This adapter is a key component for building modern, high-speed data center infrastructures. Its ability to handle multiple protocols (InfiniBand and Ethernet) through a single adapter simplifies deployment and management while providing the performance necessary for the most intensive computational tasks. The IBM CX555A represents a significant advancement in server connectivity, enabling organizations to achieve greater efficiency and accelerate their most demanding applications.
