Publication number: 20190065328Abstract: In an approach, a processor detects a transmission control protocol disconnection of a first distributed storage unit from a distributed storage network, wherein the distributed storage network comprises a set of distributed storage units. A processor identifies a transaction, wherein: the transaction is not in a final state, the transaction is a first proposal, from the first distributed storage unit, for the set of distributed storage units to store a dataset with a first revision number within the distributed storage network, and the dataset is broken into one or more data pieces to be written on the set of distributed storage units of the distributed storage network that approve the proposal. A processor identifies a timestamp of the transaction. A processor determines a stage the transaction has reached. A processor places the transaction in a final state based on the determined stage the transaction has reached.Type: ApplicationFiled: August 31, 2017Publication date: February 28, 2019Inventors: Ravi Khadiwala, Gregory R.

Patent number: 9996413Abstract: An improved system is disclosed for ensuring the integrity of data stored on a dispersed data storage network. Checksums are used to ensure integrity of both data segments and data slices. Checksums appended to data slices are checked by receiving slice servers to ensure that no errors occurred during transmission. Slice servers also periodically recalculate checksums for stored data slices to ensure that data slices have not been corrupted during storage. Checksums appended to data segments are checked when data segments are read from the storage network.Type: GrantFiled: October 9, 2007Date of Patent: June 12, 2018Assignee: International Business Machines CorporationInventors: Greg Dhuse, Vance Thornton, Jason Resch, Ilya Volvovski, Dusty Hendrickson, John Quigley

Patent number: 9578097Abstract: A computer includes a data transform algorithm, a data dispersal algorithm, and a network port. The data transform algorithm performs a data transformation on a data block to produce a transformed data block. The data dispersal algorithm performs a data dispersal function on the transformed data block to produce a plurality of data slices, wherein each of the plurality of data slices includes less than all data contained in the transformed data block. The network port is operable to transmit a plurality of write commands to a plurality of slice servers, wherein each of the plurality of write commands includes a corresponding one of the plurality of data slices. The network port is further operable to receive verification of storage of at least some of the plurality of data slices from at least some of the plurality of slice servers.Type: GrantFiled: November 19, 2010Date of Patent: February 21, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: S.

Patent number: 9483656Abstract: A method of securely storing data to a dispersed data storage system is disclosed. A data segment is arranged along the columns or rows of an appropriately sized matrix. Data slices are then created based on either the columns or the rows so that no consecutive data is stored in a data slice. Each data slice is then stored in a separate storage node.Type: GrantFiled: April 20, 2009Date of Patent: November 1, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Wesley Leggette, Jason Resch

Patent number: 8886711Abstract: 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.Type: GrantFiled: November 17, 2010Date of Patent: November 11, 2014Assignee: Cleversafe, Inc.Inventors: Srinivas Palthepu, Greg Dhuse, Vance Thornton, Andrew Baptist, Jason Resch, Ilya Volvovski, John Quigley, Zachary Mark, Bart Cilfone, S.

Patent number: 8880799Abstract: A rebuilder application operates on a dispersed data storage grid and rebuilds stored data segments that have been compromised in some manner. The rebuilder application actively scans for compromised data segments, and is also notified during partially failed writes to the dispersed data storage network, and during reads from the dispersed data storage network when a data slice is detected that is compromised. Records are created for compromised data segments, and put into a rebuild list, which the rebuilder application processes.Type: GrantFiled: March 31, 2008Date of Patent: November 4, 2014Assignee: Cleversafe, Inc.Inventors: Lynn Foster, Jason Resch, Ilya Volvovski, John Quigley, Greg Dhuse, Vance Thornton, Dusty Hendrickson, Zachary Mark

Patent number: 8351600Abstract: A distributed storage network received a data segment. The data segment is partitioned into two or more portions. A first portion hash is calculated from the first portion of data and used to encrypt the second portion of data. A hash of the encrypted second portion of data is then used to either encrypt the next portion of data (in this case, a third portion of data) or to circle back to the beginning and encrypt the first portion of the data if the second portion of data is the last in data segment. This iterative process continues until all portions of the data segment are encrypted in a sequence. In essence, the data portions of the segment are sequentially processed in some order to encrypt the various portions in that progressing order. A reverse order is used to derive the hash values and decrypt the encrypted data portions into decrypted original data to recreate the data segment.Type: GrantFiled: June 13, 2010Date of Patent: January 8, 2013Assignee: Cleversafe, Inc.Inventor: Jason Resch

Patent number: 8285878Abstract: A block-based interface to a dispersed data storage network is disclosed. The disclosed interface accepts read and write commands from a file system resident on a user's computer and generates network commands that are forwarded to slice servers that form the storage component of the dispersed data storage network. The slice servers then fulfill the read and write commands.Type: GrantFiled: October 9, 2007Date of Patent: October 9, 2012Assignee: Cleversafe, Inc.Inventors: S.

Publication number: 20070079083Abstract: Briefly, the present invention relates to an information dispersal sytem in which original data to be stored is separated into a number of data “slices” in such a manner that the data in each subset is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other data subsets. These data subsets are stored on separate storage devices as a way of increasing privacy and security. In accordance with an important aspect of the invention, a metadata management system stores and indexes user files across all of the storage nodes. A number of applications run on the servers supporting these storage nodes and are responsible for controlling the metadata. Metadata is the information about the data, the data slices or data subsets and the way in which these data subsets are dispersed among different storage nodes running over the network.Type: ApplicationFiled: April 13, 2006Publication date: April 5, 2007Inventors: S.
