IMPLEMENTING ENHANCED IO DATA CONVERSION WITH PROTECTION INFORMATION MODEL INCLUDING PARITY FORMAT OF DATA INTEGRITY FIELDS |
摘要 |
A method and controller for implementing enhanced input/output (IO) data conversion with an enhanced protection information model including an enhanced parity format of the data integrity fields (DIF), and a design structure on which the subject controller circuit resides are provided. The controller implements a protection information model including a unique parity data integrity fields (DIF) format. The unique parity DIF format enables corruption detection for RAID parity blocks. The unique parity DIF format includes a predefined size for a protection information model logical block guard cyclic redundancy check (CRC) field and a logical block Reference Tag (RT) field. A plurality of storage devices in a RAID configuration are coupled to the controller, and configured to store data and RAID parity redundancy data, and wherein a strength of RAID parity redundancy data is not reduced when a loss of a single storage device in the plurality of storage devices occurs.
