Method and arrangement for randomly storing data

Abstract

The invention relates to a method and an arrangement for randomly storing data in storage networks and/or an intranet and/or the Internet, a corresponding computer program product, and a corresponding computer-readable storage medium, which are particularly suitable for distributing and retrieving data in error-tolerant and faulty systems such as storage networks or the Internet. According to the inventive method for randomly storing data in storage networks and/or an intranet and/or the Internet, one or multiple intervals, the total length of which corresponds to the relative capacity of the system, is/are assigned to each storage system. Said intervals are represented in a [0,1) interval but can overlap with other intervals as opposed to existing strategies. A real point is then assigned to each data block within the [0,1) interval by means of a (pseudo)random function. Optionally, said point can be part of several intervals of storage systems. A uniform placement strategy is used in order to assign the data block to one of said storage systems if that is the case. The interval lengths are adjusted correspondingly if the relative capacities of the storage systems change.
