Techniques for double parity RAID are disclosed. For example, a system includes a processor coupled to a memory. The processor is configured to: receive a request to store data in data storage disks, wherein the received data is segmented into data blocks; create a distributed parity block P, wherein the distributed parity block is calculated based on the data; select a given data storage disk among the data storage disks to store the distributed plurality block, wherein the given data storage disk is rotated among the data storage disks; write the data blocks to each data storage disk among the data storage disks except the selected data storage disk; write the distributed parity block to the selected data storage disk; create a dedicated parity block Q, wherein the dedicated parity block is calculated based on the data; and write the dedicated parity block to a parity disk.
A system comprising:
A non-transitory processor-readable storage medium having stored thereon program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device to perform the following steps:
A method comprising:
