Patent number: 7930382Abstract: A system for distributed file storage includes a plurality of servers providing, to a plurality of clients, file access services for accessing files stored on the plurality of servers. A list of neighbor servers is maintained by each server. The neighbor servers are a subset of the plurality of servers. At least one server of the plurality of servers is switched into a neighbor group of servers based on network distance. Each file is stored in the form of a plurality of N pieces on N servers, the pieces being generated from the file. The list is used to obtain information for reconstructing files stored on the neighbor servers, such that any K out of the N pieces can be used to reconstruct any file.Type: GrantFiled: August 11, 2009Date of Patent: April 19, 2011Assignee: Parallels Holdings, Ltd.Inventors: Alexander Tormasov, Yury Pudgorodsky, Serguei Beloussov, Stanislav Protassov

Patent number: 7325017Abstract: The present invention provides a methodology of organization of control over the process of space or other quantitative parameter of resource allocation in computer data storages. More specifically, the present invention organizes areas of quoted space or time. A method and system of the present invention includes an establishment of quotas for an area of a file system that takes into account the belonging of a file to a certain subtree or subtrees of the file system. The quota management of the present invention is established within a usual computer system which includes a hierarchic file system, as well as a set of unique users, that could be united into groups.Type: GrantFiled: September 24, 2003Date of Patent: January 29, 2008Assignee: SWsoft Holdings, Ltd.Inventors: Alexander Tormasov, Stanislav Protassov, Serguei Beloussov

Patent number: 7293033Abstract: A computer system that allows for multiple users that each have access to shareable files. In one exemplary embodiment, each user has a user file tree that corresponds to the shareable file tree and initially contains links or pointers to selected shareable files. Each user also has a private file area to store files. If a user wishes to access a shareable file to perform an action that does not modify the shareable file, then the user file tree will point to the shareable file and allow the user to access the file. On the other hand, if the user wishes to access a shareable file and perform an operation that modifies the shareable file, the computer system will make a copy of the shareable file and place the copy in the user's private file area. Next, the computer system will modify the user's file tree such that the link that pointed to the shareable file now points to the copy of the shareable file that was placed in the user's private file area.Type: GrantFiled: October 21, 2003Date of Patent: November 6, 2007Assignee: SWsoft Holdings, Ltd.Inventors: Alexander Tormasov, Stanislav Protassov, Serguei Beloussov

Patent number: 7246211Abstract: A system and method for providing online data backup for a computer system. In which the computer system includes an intermediate block data container. The computer system may utilize the intermediate block data container to manage data block release during the online data backup process. When the data storage driver receives a request to write a block into a data area that has already been copied by the backup procedure, then the required write is performed without limitations. If the incoming write request is directed to an area not yet backed-up, then the write process is suspended and the current state of the given data area is copied to the intermediate data storage container. When the copy procedure is completed, the system will allow the write procedure to be executed. Thus, the content of the data block at the moment the backup procedure commenced is stored in the intermediate block container. The content will be copied from the intermediate block data container by the backup procedure when required.Type: GrantFiled: July 22, 2003Date of Patent: July 17, 2007Assignee: Swsoft Holdings, Ltd.Inventors: Serguei Beloussov, Stanislav Protassov, Alexander Tormasov

Patent number: 7222132Abstract: A common template file system tree is utilized by isolated operating system processes groups for effective read-only common file set access via multiple file system paths. Files are opened from different views of the file system template for write-ability access and copied into a private modification area; this is also convenient for subsequent online changes and replication.Type: GrantFiled: July 18, 2001Date of Patent: May 22, 2007Assignee: SWSoft Holdings, Ltd.Inventors: Alexander Tormasov, Serguei Beloussov, Stanislav Protassov, Yuri Pudgorodsky

Patent number: 7209973Abstract: The present invention is a system and method for distributed, highly scalable, wide area peer-to-peer network data storage. The functionally equivalent servers in the system are divided into groups. Each server maintains a dynamic list which is polled to determine the availability of the closest neighbor servers. Each server is switched between the groups of servers to optimize network connectivity parameters. Data and directory files are divided into a plurality of pieces which are stored on different servers. Files are uniformly and independently named, utilizing a tree with a common root, logical pathways, and unique file identifiers. When a server receives a client request for file system access, the plurality of file pieces are collected and sent to the client server from the neighbor servers simultaneously in order to optimize bandwidth. Servers with maximum throughput capacity are utilized for highest transmission speed and reduced processing time.Type: GrantFiled: July 30, 2001Date of Patent: April 24, 2007Assignee: SWSOFT Holdings, Ltd.Inventors: Alexander Tormasov, Sergei Beloussov, Stanislav Protassov

Patent number: 7099948Abstract: Method of efficient utilization of a single hardware system with single operating system kernel wherein a virtual environment, functionally equivalent to a full-featured operating system box, is provided to an end user without emulation of hardware, dedicated physical memory or another hardware resource. Such method is realized by separation of user processes on the level of namespace and on the basis of restrictions implemented inside the operating system kernel. Each virtual environment is invisible to other virtual environments within the system and has a completely independent root file system.Type: GrantFiled: July 30, 2001Date of Patent: August 29, 2006Assignee: SWsoft Holdings, Ltd.Inventors: Alexander Tormasov, Dennis Lunev, Sergei Beloussov, Stanislav Protassov, Yuri Pudgorodsky

Patent number: 7076633Abstract: The present invention is a system and method for utilization of computer clusters with automatic configuration and virtual environments integrated with a distributed file system as a hosting service providing platform. The virtual environment of the present invention emulates no hardware and is essentially a personal protected machine with an independent operating system that functions as a separate workstation or server.Type: GrantFiled: October 26, 2001Date of Patent: July 11, 2006Assignee: SWSoft Holdings, Ltd.Inventors: Alexander Tormasov, Dennis Lunev, Serguei Beloussov, Stanislav Protassov, Yuri Pudgorodsky

Patent number: 6961868Abstract: The disclosed invention stores files in a set of independent, functionally equal pieces. These pieces are placed on different servers of a distributed network to achieve a pre-determined level of fault tolerance. Terms of fault tolerance are defined in terms of amount of unavailable sites in the network allowing receipt and access to the data file. Maximal and minimal number of pieces available are variable method parameters. The minimal amount of data pieces k needed to restore a data file is defined. The size of each piece is approximately equal to 1/k of the original file size. The maximal amounts of pieces are defined during distribution operation and depend upon a requested fault tolerance level. Redundancy in data storage is minimized and varies dynamically by changing the total amount of pieces available. Significant increase in data transfer rate is possible because all file pieces could be transferred parallel and independently.Type: GrantFiled: July 31, 2001Date of Patent: November 1, 2005Assignee: SWsoft Holdings, Ltd.Inventors: Alexander Tormasov, Mikhail Khassine, Serguei Beloussov, Stanislav Protassov
