  • Wide stripe data storage and constructing, repairing and updating method thereof
    Patent number: 12001278
    Abstract: A wide stripe data storage and a constructing, repairing and updating method thereof are provided. In the wide stripe data storage, a stripe is (n, k, r, z) and comprises local groups and a global group comprising a rack for storing global parity blocks; each local group comprises r + 1 c racks, each rack has different storage nodes for storing data blocks or local parity blocks, the total number of the data blocks and the local parity blocks in each rack is c; one local parity block and r data blocks are stored in each local group; the number of the storage node in each rack is greater than or equal to c; c is smaller than or equal to the node fault-tolerant capability f of the wide stripe based on fault-tolerant attribute of the rack; the number of the global parity blocks is f?1; z is the total number of the racks.
