    摘要： A method begins by a processing module dispersed storage error encoding data to produce a set of encoded data slices and generating a transaction identifier regarding storage of the set of encoded data slices. The method continues with the processing module outputting a plurality of write request messages to a plurality of dispersed storage (DS) units, wherein each of the plurality of write request messages includes the transaction identifier and a corresponding one of the set of encoded data slices. The method continues with the processing module receiving write response messages from at least some of the DS units, wherein each of the write response messages includes a reference to the transaction identifier. The method continues with the processing module updating directory information regarding storage of the data to produce updated directory information when at least a write threshold number of the write response messages have been received.

    摘要： A dispersed storage (DS) method begins by issuing a plurality of write commands to a plurality of DS storage units. The method continues by receiving a write acknowledgement from one of the plurality of DS storage units to produce a received write acknowledgement. The method continues by issuing a plurality of commit commands to the plurality of DS storage units when a write threshold number of the received write acknowledgements have been received. The method continues by receiving a commit acknowledgement from a DS storage unit of the plurality of DS storage units to produce a received commit acknowledgement. The method continues by issuing a plurality of finalize commands to the plurality of DS storage units when a write threshold number of the received commit acknowledgements have been received.

    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 by a requesting device transmitting a certificate signing request to a managing unit, wherein the certificate signing request includes fixed certificate information and suggested certificate information. The method continues with the managing unit forwarding the certificate signing request to a certificate authority and receiving a signed certificate from the certificate authority, wherein the signed certificate includes a certificate and a certification signature and wherein the certificate includes the fixed certificate information and determined certificate information based on the suggested certificate information. The method continues with the managing unit interpreting the fixed certificate information of the signed certificate to identify the requesting device and forwarding the signed certificate to the identified requesting device.

    摘要： A computer a network interface and a central processing unit. The network interface communicates with a network. The central processing unit (CPU) is operable to receive a networked file system access request packet and to identify a root directory based on the networked file system access request packet. The CPU then identifies a file directory based on the root directory and the networked file system access request packet. The CPU then identifies file object metadata based on the file directory and identifies a set of slice servers based on the file object metadata and the networked file system access request packet. The CPU then issues, via the network interface, a set of commands to a set of slice servers regarding the networked file system access request packet.
