A dedicated infrastructure, recently installed at the LNF Computer Centre, houses the framework and provides control services to different LNF installations. The !CHAOS native capability of fast storage, based on the use of a non-relational database, has been finalized and tested with applications demanding high bandwidth. Thanks to its scalable design, the fast storage allows to accommodate multiple sources with sub-millisecond timing. The EU (Execution Unit) node has also been delivered and turned out to be a "Swiss Army knife" for processing both live and stored data, inserting feedbacks and in general for correlating data acquired by the CU (Control Units) nodes. A key feature of the EU is a plugin mechanism that allows to easily integrate different programming and scripting languages such as LUA, C++, Python, also exploiting the ROOT framework, the well-known scientific tool from CERN. A comprehensive description of the !CHAOS evolution, of its performances and of its use, both in scientific and industrial contexts, is presented.
