Data access and management system as well as a method for data access and data management for a computer system
DC CAFCFirst Claim
1. A data access and management system for a computer system, comprising:
- at least two data storage means;
at least one computer unit which accesses the data of the data storage means;
data transmission means for a data transmission between the data storage means and the computer unit, with the data being stored in a redundant manner in at least two of the at least two data storage means; and
means for detecting prespecified parameters of the data transmission between the data storage means and the computer unit, with data being preferably stored in a redundant manner in the data storage means as a function of said detected prespecified parameters, and with the computer unit accessing one of the data storage means as a function of said detected prespecified parameters, the data storage means comprising a second means for detecting prespecified parameters for data transmissions between said data storage means; and
wherein the data storage means copies data which is redundantly stored in the system independent of an access of the computer unit as a function of the detected prespecified parameters of data transmission between the data storage means.

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.

30. A method for data access and data management for a computer system, comprising:
-
storing data in at least two data storage means;
accessing the stored data by at least one computer unit via data transmission means, with prespecified parameters of the data transmission between the data storage means and the computer unit being determined, the data being stored in a redundant manner in at least two of the at least two data storage means as a function of the determined prespecified parameters of the data transmission, the access to the data being effected as a function of the determined prespecified parameters of the data transmission;
detecting prespecified parameters for data transmissions between the data storage means; and
shifting redundantly stored data independent of an access of the computer unit to the data as a function of the determined prespecified parameters of data transmissions between the data storage means. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
