Abstract
The application relates to writing arbitrarily sized data extents using in-line descriptors, such as headers or footers, into physical blocks to describe the data extents in those physical blocks. Some data extents may be smaller than the size of a physical block, and some data extents may be larger than the size of a physical block. A given physical block therefore includes an in-line descriptor for a data extent in that block, indicating that the data extent starts within that block and also an offset from the beginning of the block to where the data extent starts. The in-line descriptor is included within the block so that when the block is read both the data and the descriptor are read, thereby eliminating performance penalty for reading the descriptor information.
