The IBM 10N8263 represents a high-performance network interface card designed for enterprise data centers and high-demand computing environments. This 10 Gigabit Ethernet Long Reach (LR) adapter utilizes the PCI-X 2.0 Data Direct (DD) interface, ensuring high bandwidth and low latency network connections for critical business applications and data transfer requirements. It's designed to facilitate fast and reliable connections over longer distances with LR optical links, making it an ideal solution for connecting distributed data centers or implementing disaster recovery solutions that require high-speed, long-distance networking capabilities. The incorporation of PCI-X 2.0 technology provides a backwards-compatible upgrade path for older server models, allowing organizations to enhance their network speeds without the need for complete system overhauls. This network interface card is suitable for a wide range of applications, including high-performance computing, large-scale virtualization, and intensive data processing tasks, ensuring that data remains fluid and accessible across expansive network architectures.
