Abstract
Improved write allocation in data storage systems is described. A data storage system controller determines a contiguity score for an allocation area on drives of the data storage system. The contiguity score for the allocation area is determined based on an evaluation of the contiguity of physical storage blocks mapped to the allocation area. A contiguity score is then determined for a secondary allocation area within the allocation area. The contiguity score for the secondary allocation area is determined based on an evaluation of the contiguity of physical storage blocks mapped to the smaller allocation area. The physical storage blocks mapped to the secondary allocation area are a subset of the physical storage blocks mapped to the primary allocation area. Where the contiguity score for the secondary allocation area meets or exceeds the contiguity score of the primary allocation area, the secondary allocation area is selected for use.
