Abstract:
A “grain” is a unit of space allocation in a virtual disk. Grains are represented in physical storage only when used, that is, when they contain data. Grains may be located in storage using an in-memory grain-range table. The grain-range table is derived from a grain table in storage. A grain-range table includes entries for the starting grains of incrementing and or decrementing ranges; grain-table entries that do not start a range are omitted in the grain-range table. Accordingly, a grain-range table can serve as a compressed form of a grain table; in practice, the compression can be several hundred to one. This degree of compression makes it feasible to store large numbers of grain-range tables in memory in cases where it would not be feasible to store the corresponding grain tables in memory. As a result, one rather than two storage accesses are require per storage access request, resulting in a substantial performance improvement.

Claim (Index 11):
The system of  claim 9  wherein the first grain-range table identifies ranges of grains with monotonically incrementing or decrementing indices and offsets, the indices identifying grains associated with the first grain table and the offsets identifying their respective offsets from the first grain table, the first grain-range table identifying start grains and start offsets for each of the ranges identified by the first grain table.
