METHOD OF STORING A DATA SET IN A DISTRIBUTED STORAGE SYSTEM, DISTRIBUTED STORAGE SYSTEM AND COMPUTER PROGRAM PRODUCT FOR USE WITH SAID METHOD

摘要

The present invention is directed to a method of storing a data set in a storage system. Said storage system comprises a plurality of storage entities. The method comprises the following steps. A step of forming at least one data set block from said data set using a fragmentation entity. A step of encoding said at least one data set block by means of an encoding entity, wherein said encoding entity provides a plurality of encoded blocks based on said at least one data set block at an output of said encoding entity. And a step of distributing said encoded blocks amongst at least two of said storage entities using a distribution entity for storage thereof by said storage entities. Said encoding entity uses a rateless erasure encoding algorithm based on rateless codes for encoding said at least one data set block. The invention is further directed to a storage system and a computer program product.
