IMPROVED COMPUTER SYSTEM COMPRISING MULTIPLE NETWORK NODES

摘要

Computer tool for storing data, comprising a matching module (40) that is connected to storage units (38) and is designed to determine a match between virtual addresses and physical addresses in the storage units, each virtual address being assigned to at least two storage addresses. Said computer tool is characterized in that the matching module maintains a first table containing data for identifying faulty storage units as well as a second table containing data for modifying blocks of virtual addresses. Furthermore, the computer tool also comprises a recovery unit (406) which is designed, once a faulty storage unit has been restored, to update the storage addresses of said storage unit by calling the matching module by means of virtual addressed extracted from the second table on the basis of the data of the first table.
