    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.

    摘要: A method begins with the specific computing device token sending a distributed storage network (DSN) access request to DSN memory via the generic computing device. The DSN access request identifies specific computing device operation information that is stored as one or more of-sets of encoded data slices in the DSN memory. The method continues with the specific computing device token receiving the one or more of sets of encoded data slices from the DSN memory via the generic computing device and decoding the one or more of sets of encoded data slices to retrieve the specific computing device operation information. The method continues with enabling the generic computing device to function as a specific computing device in accordance with the specific computing device operation information.

    摘要: A computing device includes a central processing unit (CPU) and a memory system module. The CPU includes a data dispersed storage error coding (DSEC) module operable to DSEC decode a set of encoded ingress data slices to recapture ingress data and DSEC encode egress data to produce a set of encoded egress data slices, an instruction DSEC module operable to DSEC decode a set of encoded instruction slices to recapture an instruction, and an arithmetic logic unit (ALU) operable to, execute the instruction on the ingress data and execute the instruction to produce the egress data. The memory system module is operable to coordinate retrieval of the set of encoded ingress data slices from memory, coordinate retrieval of the set of encoded instruction slices from the memory, and coordinate storage of the set of encoded egress data slices in the memory.
