摘要： A server computer at a first storage sub-system of a distributed storage system receives from a client a first client request for an object. If the object is not present in the first storage sub-system, the server computer identifies a second storage sub-system of the distributed storage system as having a replica of the requested object, the requested object including content and metadata. The server computer submits an object replication request for the requested object to the second storage sub-system and independently receives the content and metadata of the requested object from the second storage sub-system. The server computer generates a new replica of the object at the first storage sub-system using the received metadata and content and returns the metadata of the new replica of the object to the client.

摘要： A distributed storage system stores data for files. A first blob (binary large object) of data is received. The first blob is split into one or more first chunks of data. Content fingerprints for the first chunks of data are computed. The first chunks of data are stored in a chunk store while and their content fingerprints are stored in a store distinct from the chunk store. A second blob of data is received. The second blob is split into one or more second chunks of data. Content fingerprints for the second chunks of data are computed. Then for a second chunk of data whose content fingerprint matches a content fingerprint of a first chunk of data, a second reference to the corresponding first chunk of data that has a matching content fingerprint is stored, but the second chunk of data is not stored.

摘要： A method for managing multiple generations of an object within a distributed storage system is implemented at a computing device. The computing device receives metadata and content of a first generation of an object from a first client connected to the distributed storage system and stores the first generation's metadata and content within a first storage sub-system. The computing device receives metadata and content of a second generation of the object from a second client connected to the distributed storage system and stores the second generation's metadata and content within a second storage sub-system. The computing device independently replicates the first generation's metadata and content from the first storage sub-system to the second storage sub-system and replicates the second generation's metadata and content from the second storage sub-system to the first storage sub-system such that both storage sub-systems include a replica of the object's first and second generations.

摘要： A distributed storage system has multiple instances. There is a plurality of local instances, and at least some of the local instances are at physically distinct geographic locations. Each local instance is configured to store data for a non-empty set of blobs in a plurality of data stores having a plurality of distinct data store types. In addition, each local instance stores metadata for the respective set of blobs in a metadata store distinct from the data stores. There is also a plurality of global instances. Each global instance is configured to store data for zero or more blobs in zero or more data stores and store metadata for all blobs stored at any local or global instance. The system selects one global instance to run a replication module that replicates blobs between instances according to blob policies. Some systems also include dynamic replication based on user needs.

摘要： A method is provided. The method determines a set of components to include in an enterprise module. Further, the set of components is divided into a set of platform dependent components and a set of platform independent components. In addition, abstract computer code is prepared for each of the components in the set of platform dependent components according to at least one of a plurality of high-level abstract computer languages. Further, the abstract computer code is provided to a transmogrifier to automatically generate platform dependent source code. In addition, the platform independent source code is prepared for the set of platform independent components. The enterprise object code is generated by compiling and linking the platform dependent source code and the platform independent source code.
