Abstract
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.

12. A method for a computer unit to access data over a network by receiving data from at least one of a plurality of data storage devices in which data is stored redundantly as a function of prespecified parameters of the data transmission between the computer unit and the plurality of data storage devices independent of an access of the computer unit, the method comprising the steps of:
-
detecting the prespecified data transmission parameters; sending a request to a first data storage device for access to the redundantly stored data as a function of the detected prespecified parameters; and receiving the requested data from the first data storage device.
