Meta-information managing method for distributing data blocks or objects over computer-readable storage media, especially in fault-tolerant systems, combines extent and offset fraction for uniform data distribution

摘要

According to the method data are stored in extents whose addresses are distributed uniformly over the storage media by use of an address bit fraction and an offset bit fraction. The addressing jumps the storage location no longer required for storing the extents coherently within consecutive ranges on a memory unit within the memory system, but in distributed mode is linked logically with other ranges of a memory system. The invention also relates to a corresponding computer program product and a computer-readable storage medium.
