Abstract
A method for embedding integrity metadata. In one exemplary embodiment, a plurality of integrity metadata segments is determined. Each integrity metadata segment is associated with a segment of user data. The user data is mapped to a plurality of physical sectors, each physical sector containing a segment of user data and the associated integrity metadata segment. For one exemplary embodiment, a common I/O data block size is determined, and its data is mapped into a number of 512-byte sectors. The number of 512-byte sectors corresponds to the number required for the common I/O data block size plus one or more additional 512-byte sectors. This creates additional space in each sector to accommodate the integrity metadata. Integrity metadata for each data segment of the common I/O size is determined. The integrity metadata for each sector is mapped to the additional space of each sector.
