This talk gives an overview about the recent development advances in the Scalla/xrootd software suite for data access. The topics covered start from the Composite Cluster Name Space service, which is used as a standpoint for the POSIX file system access via FUSE. Then, the Clustering Manager Server (a higher performance and more powerful evolution of olbd) is unveiled, as well as the Cluster Globalization and Wide Area Network data access features, which constitute the building blocks for a scalable, high performance and reliability Storage System fully distributed via Wide Area Network. One more item in the list is constituted by the Virtual Staging capabilities, for which, with a minimum effort, several aggregated clusters can fetch files from one another, and recover autonomously from data losses.
