Abstract: A data storage system, according to certain aspects, automatically determines the accuracy of replication data when performing data backup operations. For instance, the system performs data backup using replication data rather than source data to reduce the processing load on the source system. The backup data is then associated with the source data as if the backup had been performed on the source data. If the replication system fails, then backing up replication data results in backup data that does not accurately reflect the source data. The system automatically determines the accuracy of replication data during data backup.

Abstract: Deduplication of virtual-machine disk images and other disk images can involve identifying the first clusters in a file. The clusters are hashed. The first-in-file hashes (generated from first-in-file clusters) are stored in an in-memory index, while the full set of hashes is streamed in order to find matches with the hashes stored in the in-memory index. First-in-file hashes in the stream are compared, while other hashes in the stream are compared only if the immediately preceding hash resulted in a match. Comparing non-first-in-file hashes requires disk accesses, but since such comparisons are conditioned on first-in-file matches, there are relatively likely to result in sequences of matches. The net effect is a relatively fast deduplication with compression approaching that resulting from a full comparison of all hashes.

Abstract: A memory device is designed to store data in multilevel storage cells (MLC storage cells). The memory device includes a controller that dynamically writes data to the storage cells according to a first MLC density or a second MLC density. The second density is less dense than the first density. For example, the controller can determine to use the first density when there is sufficient write bandwidth to program the storage cells at the first density. When the write throughput increases, the controller can program the same MLC storage cells at the second density instead of the first density, using the same program process and voltage.

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.
