摘要： A method includes issuing write commands to DS storage units regarding encoded data slices. A write command causes a storage unit to store an encoded data slice, but not allow access to the stored encoded data slices. The method includes receiving write acknowledgements from at least some of DS storage units to produce received write acknowledgements. The method includes, when a write threshold number of the received write acknowledgements have been received within a given time frame, issuing commit commands to the DS storage units. A commit command causes the storage unit to allow access to the stored encoded data slice. The method includes, when the write threshold number of the received write acknowledgements have not been received within the given time frame, issuing rollback commands to the DS units. A rollback command causes the storage unit to continue to not allow access to the stored encoded data slice.

摘要： A method begins by a processing module of a dispersed storage network (DSN) ascertaining a decode threshold value for dispersed storage error encoding data for storage in storage units of the DSN. The method continues with the processing module determining a total width value for the dispersed storage error encoding based on the decode threshold value, a number of selected sites within the DSN, and a number of selected storage units of the selected sites. The method continues with the processing module determining logical storage slots within the selected storage units based on the total width value, the number of selected, and the number of selected storage units. The method continues with the processing module writing a set of encoded data slices to a total width value of the logical storage slots within at least some of the selected storage units of the selected sites based on a slice-to-slot mapping.

摘要： A method includes a dispersed storage (DS) processing module receiving a slice access request that includes a slice name. The method continues by obtaining one or more revision numbers for the slice access request. The method continues for each combination of revision number and the slice name, by performing a deterministic function on the combination to produce a slice location table index value. The method continues by accessing a slice location table utilizing the slice location table index value to obtain a slice location. The method continues by accessing a slice utilizing the slice location. The method continues by generating a slice access response based on the accessing of the slice and sending the slice access response to a requesting entity.

摘要： A method begins by a dispersed storage (DS) processing module determining to expand a hierarchical ordered index structure and retrieving a root index node. The method continues with the DS processing module identifying immediate children index nodes, dividing the immediate children index nodes into sets of children index nodes, creating, for each of the sets of children index nodes, a sub-root index node to produce a set of sub-root index nodes, creating a new root index node to include entries for each of the sub-root index nodes of the set of sub-root index nodes, and temporarily storing the new root index node and the set of sub-root index nodes in a dispersed storage network (DSN). When the root index node has not changed, the method continues with the DS processing module updating the hierarchical ordered index structure with the new root index node and the set of sub-root index nodes.
