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.

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 dispersed storage network utilizes a virtual address space to store data. The dispersed storage network includes a processing unit operable to slice a data segment of a data object into data slices and create a slice name for each of the data slices. The slice name includes an identifier of the data object and a virtual memory address of a virtual memory associated with the dispersed storage network. The processing unit further outputs each of the data slices and the respective slice names to a corresponding storage unit for storage of the data slices therein.

摘要： A method begins with a processing module receiving, from a requesting device, a data storage request that includes data for storage. The method continues with the processing module determining whether substantially identical data is currently stored in a dispersed storage network (DSN) memory. The method continues with the processing module encoding at least a portion of the data using an error coding dispersal storage function to produce a set of encoded data slices, sending the set of encoded data slices to the DSN memory for storage therein, and generating a unique retrieval matrix for the requesting device, wherein the unique retrieval matrix identifies a sub-set of encoded data slices of the set of encoded data slices for subsequent retrieval of the at least a portion of the data, when the substantially identical data is not stored in the DSN memory.
