摘要:
An integrated client computer for accessing a dispersed data storage network is disclosed. A client program operating on the client computer accepts commands from a user and in response, issues network messages to a plurality of slice servers implementing a dispersed data storage network. Data slices can be read, written or modified using the disclosed integrated client computer.
摘要:
A data object interface to a dispersed data storage network is disclosed. The disclosed interface accepts read and write commands from a client computer and generates network commands that are forwarded to slice servers that form the storage component of the dispersed data storage network. The slice servers then fulfill the read and write commands.

A computer a network interface and a central processing unit. The network interface communicates with a network. The central processing unit (CPU) is operable to receive a networked file system access request packet and to identify a root directory based on the networked file system access request packet. The CPU then identifies a file directory based on the root directory and the networked file system access request packet. The CPU then identifies file object metadata based on the file directory and identifies a set of slice servers based on the file object metadata and the networked file system access request packet. The CPU then issues, via the network interface, a set of commands to a set of slice servers regarding the networked file system access request packet.

A method begins by a processing module receiving a data storage request, wherein the data storage request includes data and a data identifier (ID). The method continues with the processing module dispersed storage error encoding the data to produce a set of encoded data slices and determining a data dispersed storage network (DSN) address. The method continues with the processing module sending the set of encoded data slices to a DSN memory for storage at the data DSN address and updating a directory file with path information corresponding to the data ID and the data DSN address to produce an updated directory file. The method continues with the processing module dispersed storage error encoding the updated directory file to produce a set of encoded updated directory slices and sending the set of encoded updated directory slices to the DSN memory for storage at a directory DSN address.
摘要:
A distributed storage network receives a data object and determines a size of the data object. The network then determines whether the data object should be segmented into fixed size segments or variable sizes segments based upon some variable-length algorithm. If the fixed approach is selected, the data object is segmented into two or more fixed size segments with attached header information and the information is further processed using error coding dispersal storage functions within the network. If the variable approach is selected, the data object is segmented into two or more variable-sized segments with attached header information and the information is further processed using error coding dispersal storage functions within the network. Both the variable and fixed approaches enable storage of error-correctable data slices in a distributed storage manner.

A method begins by a dispersed storage (DS) processing module obtaining a plurality of data objects for storage in a dispersed storage network (DSN) and determining one or more common data object aspects of a data object of the plurality of data objects. The method continues with the DS processing module disperse storage error encoding at least a portion of the data object to produce a set of encoded data slices and generating a set of DSN addresses for the set of encoded data slices, wherein each of the set of DSN addresses includes a field referencing the one or more common data object aspects. The method continues with the DS processing module outputting the set of encoded data slices for storage in the DSN based on the set of DSN addresses.

A method begins by a processing module identifying an encoded data slice to be rebuilt, selecting a decode threshold number of dispersed storage (DS) units of a storage set of DS units, generating a decode threshold number of key pairs, wherein a key pair of the decode threshold number of key pairs corresponds to a DS unit of the decode threshold number of DS units, and sending partial rebuilding requests to the decode threshold number of DS units, wherein a partial rebuilding request of the partial rebuilding requests includes the key pair. The method continues with the processing module receiving encrypted partial encoded data slices, wherein an encrypted partial encoded data slice received from the corresponding DS unit includes a multiple encryption, using the key pair, of a partial encoded data slice and decoding the encrypted partial encoded data slices to rebuild the encoded data slice.
