Data access and management system and data access and management method for a computer system

The present invention permits improved data access and improved data management in a computer system. To this end, data are divided into individual partial data (F) and stored in cells (Z) of storage devices (C). In such a way that the partial data (F) being accessed and managed are present in the computer system in a redundant manner. Computer units (CL) are able to access the redundantly stored data. The fact that they are stored in the storage devices (C) ensures that the computer units (CL) accessing said data are supplied more rapidly. This is achieved in particular owing to the fact that the redundantly stored data are accessed in accordance with parameters of data transmissions between the computer units (CL) and the data storage devices (C) and that, in accordance with said data transmission parameters, the redundantly stored data are moved to and from the data storage devices (C) by corresponding copy and delete operations.
