ENSURING THE RELIABILITY OF INFORMATION IN A DISTRIBUTED DATABASE

Abstract

Block systems are so named because the data stored in them is split into blocks of the same size. A data block is not a file, not a complete object, but just some data in a chunk of a fixed size (in English - chunk). The data file can be placed in a finite number of blocks, and if the last of these blocks is left unfilled, it will still have the same fixed size as the filled blocks. The server accesses these blocks through a storage attached network (SAN).
