  !CHAOS is an INFN project aimed at creating the communication framework and the services needed for the definition of a new control system standard, mainly addressed to large experimental apparatus and particle accelerators. !CHAOS is under test at DAΦNE accelerator and has been developed to overcome the strong requirements throughput of new accelerators, like superB. One of the main components of the framework is the historical engine (HST Engine), a cloud-like environment optimized for the fast storage of large amount of data produced by the control system’s devices and services (I/O channels, alerts, commands, events, etc.), each with its own storage and aging rule. The HST subsystem is designed to be highly customizable, such to adapt to any desirable data storage technologies, database architecture, indexing strategy and fully scalable in each part. The architecture of HST Engine and the results of preliminary tests for the evaluation of performance are presented.
