This includes file names, locations, and permissions. Metadata is managed by at least one Metadata Controller (MDC) . When a client wants to open a file, it asks the MDC for the "map" to that file over a standard Ethernet network .

Accessing the Xsan filesystem is not as simple as plugging in a Thunderbolt cable. Several technical prerequisites must be met: Xsan is Apple’s clustered 64-bit file system that

is a high-performance 64-bit clustered file system developed by Apple for macOS that allows multiple computers to simultaneously read and write to the same storage volumes over a high-speed network. By moving data over Fibre Channel connections, Xsan provides the rapid, centralized access to massive datasets required for demanding professional workflows like 4K video editing, scientific research, and data-intensive server operations. The Core Architecture of Xsan

While Apple has integrated Xsan management into the command line ( xsanctl ) and removed the standalone "Server" app interface in recent years, the underlying technology remains a powerful tool for collaborative workflows. As NVMe storage and 100Gb Ethernet become more common, Xsan continues to evolve, providing the high-speed access required by the next generation of creative professionals. When a client wants to open a file,

– Xsan uses two distinct communication pathways:
