SDXI is a standard for a memory-to-memory data mover and acceleration interface that is extensible, forward-compatible, and independent of I/O interconnect technology. Among other features, SDXI standardizes an interface and architecture that can be abstracted or virtualized with a well-defined capability to quiesce, suspend, and resume the architectural state of a per-address-space data mover.

In today's data-driven world, the demand for high-speed and reliable storage networks is constantly increasing. Fibre Channel (FC) has long been a preferred choice for storage area networks (SANs) due to its performance, scalability, and robustness. To meet the evolving needs of modern virtualized data centers, Fibre Channel introduced a groundbreaking feature known as Virtual Lanes (VLs), which allows for efficient resource utilization and enhanced Quality of Service (QoS).
