Compressed Data Integrity Veritification Using Data Integrity Field

A system for compressed data integrity verification, comprising:

• one or more processors and one or more storage devices storing instructions that are operable, when executed by the one or more processors, to cause the one or more processors to perform operations comprising:
• receiving a write IO containing uncompressed data;
• dividing the uncompressed data into a set of uncompressed data blocks;
• adding a respective first Data Integrity Field (DIF) to each respective uncompressed data block of the set of uncompressed data blocks;
• compressing the set of uncompressed data blocks and respective first DIF to create compressed data;
• dividing the compressed data into a set of compressed data blocks;
• adding a respective second DIF to each respective compressed data block of the set of compressed data blocks;
• and
• verifying the compressed data is able to be accurately decompressed to recreate the uncompressed data, by:
• decompressing the compressed data to create a set of decompressed data blocks and respective decompressed first DIF;
• and
• using the respective decompressed first DIF to verify the decompressed data contained in each of the decompressed data blocks.
