Abstract
A cold storage system includes data storage devices and parity storage devices. The data storage devices and the parity storage devices form a multiple dimensional matrix which has multiple rows and multiple columns. A controller receives a data write request, selects a data storage device for storing a plurality of data blocks, and writes the data blocks sequentially into memory blocks of the selected data storage device, each data block belonging to a row stripe distributed over one row of the matrix and to a column stripe distributed over one column of the matrix. The controller also generates a row protection block for the row stripe and a column protection block for the column stripe, and writes the row protection block and the column protection block to parity storage devices in the system.
