Patent number: 11061928Abstract: A method is described that includes providing a snapshot counter for a storage system implemented with multiple distributed consistent database instances. The method further includes recognizing the taking of a snapshot of the storage system by incrementing the snapshot counter from a first snapshot counter value to a second snapshot counter value. The method further includes, in response to a first change for one of the distributed consistent databases subsequent to the taking of the snapshot, performing the following: saving state information of the distributed consistent database as the state information existed prior to the change and associating the first snapshot counter value to the state information. Associating the second snapshot counter's value with the distributed consistent database having the first change. Another method for the taking of a snapshot of a distributed consistent database is also described.Type: GrantFiled: April 16, 2019Date of Patent: July 13, 2021Assignee: SCALITY, S.A.Inventors: Giorgio Regni, Vianney Rancurel, David Pineau, Guillaume Gimenez, Jean-Marc Saffroy, Benoit Artuso

Patent number: 10754878Abstract: A storage system is described. The storage system includes an object store having a plurality of objects to implement a quota policy or a part of a relational database. The plurality of objects include a first plurality of immutable objects, a second plurality of immutable objects and a head object. The first plurality of immutable objects contain information kept within the database. The second plurality of immutable objects contain a hierarchy of pages for accessing the first plurality of immutable objects. The plurality of objects also include a mutable object that contains a mapping table that maps identifiers of the pages to identifiers of objects of the second plurality of immutable objects. The information is one of: quota policy information; information within a table of a relational database; a stripe of a thin provisioned file.Type: GrantFiled: December 19, 2016Date of Patent: August 25, 2020Assignee: SCALITY, S.AInventors: Giorgio Regni, Vianney Rancurel, Guillaume Gimenez, Jean-Marc Saffroy, David Pineau, Benoit Artuso

Patent number: 10545826Abstract: A method is described. The method includes fragmenting data of an object for storage into an object storage system into multiple data fragments and performing a first error correction encoding process on the data to generate one or more parity fragments for the object. The method also includes sending the multiple data fragments and the one or more parity fragments over a network to different storage servers of the object storage system. The method also includes performing the following at each of the different storage servers: i) incorporating the received one of the multiple data fragments and one or more parity fragments into an extent comprising multiple fragments of other objects; ii) performing a second error correction encoding process on multiple extents including the extent to generate parity information for the multiple extents; and, iii) storing the multiple extents and the parity information.Type: GrantFiled: May 25, 2017Date of Patent: January 28, 2020Assignee: Scality, S.A.Inventors: Giorgio Regni, Vianney Rancurel, Lam Pham Sy

Patent number: 10366070Abstract: A storage system is described. The storage system includes an object store having a plurality of objects containing information. The storage system also includes a cluster of locking nodes to implement a distributed synchronization locking mechanism. The cluster of locking nodes include a proposer node and a plurality of acceptor nodes. The proposer node to broadcast to the acceptor nodes a proposed lock on at least some of the information. The acceptor nodes to vote on the proposed lock based on respective locking information kept in a local store of each acceptor node.Type: GrantFiled: February 20, 2015Date of Patent: July 30, 2019Assignee: Scality S.A.Inventors: Giorgio Regni, Vianney Rancurel, Mudit Verma

Patent number: 10248682Abstract: An apparatus is described including a large scale distributed storage system. The large scale distributed storage system includes an object store. The large scale distributed storage system includes a plurality of connector nodes coupled to the object store. The connector nodes are to provide access to the object store for respective users that are respectively coupled to the connector nodes. The connector nodes are to provide the following services for the respective users: a snapshot of a storage system implemented within said object store; branching from a snapshot taken of said storage system implemented within said object store; locking of information kept within said storage system implemented within said object store.Type: GrantFiled: February 20, 2015Date of Patent: April 2, 2019Assignee: Scality, S.A.Inventors: Giorgio Regni, Vianney Rancurel, David Pineau, Guillaume Gimenez, Jean-Marc Saffroy, Benoit Artuso, Mudit Verma

Patent number: 9311135Abstract: A computer implemented method and system for generating secure universal object identifiers on a multipurpose storage system is disclosed. According to one embodiment, a system comprises a client system in communication with a network. An application server is in communication with the network. A storage cluster is in communication with the network. The storage cluster has a plurality of storage nodes. The client system stores a data object via the application server.
