Abstract: The described technology is generally directed towards storing an object in different ways based upon evaluating the object's size information. An object classified as small with respect to a threshold size value is an embedded object, and has its object metadata and object data stored in an object table that generally references object data. A non-embedded object can be further classified based on its object metadata size, as a normal object (metadata size below a threshold size) or an inflated object (metadata size not below the threshold size). A normal object has its object data stored in a repository (in a chunk in a chunk store) and its object metadata and pointer to the chunk stored in the object table. An inflated object has its object metadata and object data stored in the repository (in a chunk) with a pointer to the chunk stored in the object table.

Abstract: The invention is notably directed to computer-implemented methods and systems for managing datasets in a storage system. In such systems, it is assumed that a (typically small) subset of datasets are labeled with respect to their relevance, so as to be associated with respective relevance values. Essentially, the present methods determine, for each unlabeled dataset of the datasets, a respective probability distribution over a set of relevance values. From this probability distribution, a corresponding relevance value can be obtained. This probability distribution is computed based on distances (or similarities), in terms of metadata values, between said each unlabeled dataset and the labeled datasets. Based on their associated relevance values, datasets can then be efficiently managed in a storage system.

Abstract: Embodiments are described for reducing memory usage and disk I/O's for reading and writing streams in a deduplication storage system. Generations of backups of a stream can be tracked for the stream. In the first generation (first backup), stream data is ingested, segmented, and written to disk without looking up a fingerprint of each segment, to save disk I/O's and memory. After the first generation, an amount of stream data processed is tracked, and at dynamically tunable increments of data processed, a fingerprint index lookup is performed to disk. The fingerprint index is read into memory and subsequent fingerprint lookups are preformed to cache, until a next dynamically tunable fingerprint lookup to disk. The dynamically tunable increment of processed data can be randomly reset.

However, to prevent the amount of metadata stored in the management region from increasing, if write data meets a predetermined condition, the storage apparatus does not perform the deduplication process, and suppresses creation of metadata of the write data.

When any location hint refers to NVMe-oF qualified names not included in the immediately preceding query by the discovery service, the immediately preceding query is processed again.
