DISTRIBUTED DATA STORAGE SYSTEM Russian patent published in 2022 - IPC G06F7/72 H03M7/18 

FIELD: computer technology.

SUBSTANCE: invention relates to computational modular systems and is intended to prepare source files for reliable distributed storage by transferring residual classes to the system and to restore received files received from a distributed environment in case of an error or non-receipt of one of the parts of the file. The system contains n+1 registers for storing residues by modulo p_i, where n is the number of working modules p_i of the residual class system, n+1 blocks of multiplication by k_i, a product adder, an error correction block, and an error correction block contains a comparison block and n+2 multiplexers, n+1 blocks for finding residues by modulo p_i, distributed storage, a block for finding the remainder by modulo and n+1 blocks for finding the remainder by modulo , where is the operating range, is the full range of the system of residual classes, in blocks of multiplication by k_i multiplication by is performed, and the modules will be restricted p₁<p₂<p₃<…<p_n<p_n+1 and p_n+1>p_n⋅p_n-1, while n+1 blocks for comparison with the working range are introduced into the error correction block.

EFFECT: reduction in hardware and time costs of error correction of modular numbers obtained from distributed data storage systems.
