摘要： An improved system for accessing data within a distributed data storage network (“DDSN”) is disclosed. In a system implementing the disclosed invention, traffic is routed to individual slice servers within the DDSN in accordance with objective criteria as well as user-defined policies. In accordance with one aspect of the disclosed invention, when a data segment is written to a DDSN, the segment is divided into multiple data slices, which are simultaneously transmitted to different slice servers. In accordance with another aspect of the disclosed invention, when a data segment is read from a DDSN, a list of slice servers, each containing a data slice that could be used to reconstruct the requested data segment, is assembled, and sorted in accordance with a preference rating assigned to each of the slice servers. Sufficient data slices to reconstruct the data segment are then read in accordance with the preference ranking of the slice servers.

摘要： A method begins with a slice server receiving a request to access a virtual digital data storage vault. The method continues by determining whether the virtual digital data storage vault is a first virtual digital data storage vault or a second virtual digital data storage vault. The slice server supports a portion of each of the first and the second virtual digital data storage vaults. When the virtual digital data storage vault is the first or the second virtual digital data storage vault, the method continues by determining whether the request is valid. When the request is valid, the method continues by executing the request to generate a response.

摘要： An improved system is disclosed for ensuring the integrity of data stored on a dispersed data storage network. Checksums are used to ensure integrity of both data segments and data slices. Checksums appended to data slices are checked by receiving slice servers to ensure that no errors occurred during transmission. Slice servers also periodically recalculate checksums for stored data slices to ensure that data slices have not been corrupted during storage. Checksums appended to data segments are checked when data segments are read from the storage network.

摘要： A rebuilder application operates on a dispersed data storage grid and rebuilds stored data segments that have been compromised in some manner. The rebuilder application actively scans for compromised data segments, and is also notified during partially failed writes to the dispersed data storage network, and during reads from the dispersed data storage network when a data slice is detected that is compromised. Records are created for compromised data segments, and put into a rebuild list, which the rebuilder application processes.

摘要： A method for reading data from a dispersed data storage network that includes a plurality of slice servers. The method begins by accessing a list of slice servers of the plurality of slice servers, wherein each slice server on the list stores at least one data slice associated with a data segment of the data. The method continues by transmitting read requests to at least some of the slice servers on the list. The method continues by receiving a data slice from a slice server on the list. The method continues by determining whether a threshold number of data slices has been received. The method continues, when the threshold number of data slices has been received, assembling the data segment from at least the threshold number of data slices.

摘要： A slice server includes a network port, a central processing unit, and memory. The central processing unit (CPU) is operable to receive, via the network port, a request to access a virtual digital data storage vault. The CPU then determines whether the slice server supports the virtual digital data storage vault. When the slice server supports the virtual digital data storage vault, the CPU determines whether the request is valid. When the request is valid, the CPU executes the request to generate a response.

摘要： A method begins by a processing module obtaining an encoded data slice and an associated slice name. The method continues with the processing module determining a dispersed storage (DS) unit for storing the encoded data slice based on at least one of the encoded data slice and the associated slice name and estimating a performance level of the DS unit to produce an estimated DS unit performance level. The method continues with the processing module sending the encoded data slice to the DS unit for storage therein and when the estimated DS unit performance level compares unfavorably with a performance threshold, facilitating storage of the encoded data slice in temporary memory to produce a temporarily stored encoded data slice, wherein the temporarily stored encoded data slice is retrieved in response to a retrieval request when confirmation of the DS unit storing the encoded data slice has not been received.
