Abstract: 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.

Abstract: A method begins with a processing module receiving a request to store a data object from a first requesting device. The method continues with the processing module determining that a substantially similar version of the data object is currently stored in a DSN.

Abstract: A method for storing a data object includes identifying data segments of the data object. The method continues with generating key indexes for the data segments. For a data segment, the method continues with accessing data segment key information based on a corresponding key index of the plurality of key indexes to determine whether an encryption key has been generated for a similar data segment. When the encryption key has been generated for the similar data segment, the method continues with using the encryption key to encrypt the data segment to produce an encrypted data segment. The method continues with compressing the encrypted data segment to produce a compressed and encrypted data segment. The method continues with storing the compressed and encrypted data segment in a storage unit of a dispersed storage network (DSN).

Abstract: 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.

Abstract: A method begins with a group of storage units of a dispersed storage network (DSN) receiving a common access request. The method continues with each storage unit of the group of storage units interpreting the access request to determine whether the storage unit is an intended recipient of the access request, where storage units of a sub-set of storage units of the group of storage units are intended recipients. The method continues with each storage unit of the sub-set of storage units determining a type of the access request and a level of the access request. When the access request is a read request, the method continues with each storage unit of the sub-set of storage units retrieving each encoded data slice having an identifier of its slice address substantially matching the a given identifier of the level to produce a retrieved set of encoded data slices.
