Focus Areas:

File Systems impose structure on the address space of one or more physical or virtual devices. Starting with local file systems over time additional file systems appeared focusing on specialized requirements such as data sharing, remote file access, distributed file access, parallel files access, HPC, archiving, security etc.. Due to the dramatic growth of unstructured data files as the basic units for data containers are morphing into file objects providing more semantics and feature-rich capabilities for content processing. This presentation will categorize and explain the basic principles of currently available file systems (e.g. local FS, shared FS, SAN FS, clustered FS, network FS, distributed FS, parallel FS, object FS, ...). It will also explain technologies like NAS aggregation, NAS clustering, scalable NFS, global namespace, parallel NFS, storage grids and cloud storage. All of these file system categories are complementary. They will be enhanced in parallel with additional value added functionality. New file system architectures will be developed and some of them will be blended in the future. Learning Objectives Understand the basic principles of different files system architectures Understand how file systems evolved over time Being prepared to discuss, position and recommend the most appropriate file system for a customer solution
