  • Publication number: 20220131865
    Abstract: A method and a system for checking permissions compatibility between a configuration management system and an orchestration system of a computing cluster are disclosed. The method comprises: identifying a request to approve a change in at least one file of the computing cluster. Retrieving from a repository of the configuration management system an identity of a user for performing the change. Acquiring a denial response or an approval response received in response to a query provisioned to the orchestration system, the query is for rights to change the at least one file using the identity of the user. In response to the approval response, entering the approval response, into the configuration management system for confirming the checking permissions compatibility is approved. In response to the denial received, sending a message to the configuration management system, the message is indicative that the checking permissions compatibility is not approved.

  • Patent number: 11108559
    Abstract: A method of integrating a distributed ledger represented by a blockchain with a distributed storage network (DSN) begins by sending a proof of existence request to the DSN, the proof of existence request including an object name, an object version, a start time and an end time. The method continues by reading the object metadata for the sent object name. The method continues by checking a revision history from object metadata associated with the sent object name to ensure the object existed by the start time through the end time with no deletions and, if the object did not exist by the start time through the end time with no deletions, rejecting the proof of existence request and returning an error response. If the object did exist by the start time on through the end time with no deletions, the method continues by producing and returning an attestation comprising verification information related to the object.

  • Patent number: 10678813
    Abstract: A computer determines whether it has received user input or a node within a replica set has reached a capacity threshold. Based on receiving user input or determining that a node within a replica set has reached a capacity threshold, creating a snapshot of the data stored in the replica set and partitioning the data based on the created snapshot. The computer then initializing nodes within a new replica set and moves a partition from the original replica set to the new replica set before deleting the other partition from the old replica set.

  • Patent number: 10361995
    Abstract: Embodiments of the present invention provide a means for managing portable Internet Protocol (IP) addresses and virtual machine persistent storage. The invention includes defining a set of available portable IP addresses. When a request for a portable IP address is received from a first virtual machine (VM), a first portable IP address is assigned to the first VM. The assignment of the first portable IP address to the first VM extends for a predetermined amount of time and requires a lease renewal to extend the assignment.

  • Patent number: 10341181
    Abstract: A method and system for implementing a replica network configuration in a distributed system is provided. The system includes a memory having computer readable instructions, and one or more processors for executing the computer readable instructions. The computer readable instructions include generating a replica node that is assigned a computer readable storage medium and a processor, receiving, at the computer readable storage medium, a network configuration of the replica node from a system administrator, automatically generating, using the processor, a unique identifier (UUID) for the replica node, transmitting the UUID to a plurality of replica nodes of the distributed system arranged in the replica network configuration, and storing the UUID in the computer readable storage medium, wherein the computer readable storage medium is a persistent storage.

  • Patent number: 10083217
    Abstract: A computer-implemented method, computerized apparatus and computer program product, the method comprising: receiving a proposed reconfiguration command, the proposed reconfiguration command indicating a modification of a protocol version employed by a plurality of replica-set processes to an updated protocol version; tentatively agreeing on at least one proposed command following the proposed reconfiguration command, the at least one proposed command being in accordance with the updated protocol version, wherein said tentatively agreeing is decided prior to agreeing on the reconfiguration command; and, responsive to agreeing on the reconfiguration command, committing the tentatively agreed at least one proposed command.

  • Patent number: 10078464
    Abstract: An approach is provided in which a replicated memory system replicates a set of data between multiple replicas, whereby each of the replicas includes a sequence update number corresponding to an update state of its respective set of data. At least one of the replicas identifies a number of replicas to which it connects and, in turn, the replicas select one of replicas as a leader replica based at least on the selected leader replica's sequence update number and the number of replicas to which the selected leader connects.

  • Patent number: 10049011
    Abstract: A processor-implemented method, for continuing operation of a quorum based system is provided. The method detects a loss of quorum. A plurality of speculative configurations is created, whereby each speculative configuration is isolated from other speculative configurations in the quorum based system. Each speculative configuration continues to order requests during the creation of speculative configurations. The method selects and starts one of the plurality of speculative configurations as a new operational configuration. Ordered requests continue to the new operational configuration. The original configuration of the quorum based system is restarted in response to the plurality of speculative configurations not being isolated.

  • Patent number: 9547726
    Abstract: A method for enabling access to a data resource, which is held on a file server (25) on a first local area network (LAN) (21a), by a client (28) on a second LAN (21b). A proxy receiver (48) on the second LAN (21b) intercepts a request for the data resource submitted by the client (28) and transmits a message via a wide area network (WAN) (29) to a proxy transmitter (52) on the first LAN (21a), requesting the data resource. The proxy transmitter (52) retrieves a replica of the data resource from the file server (25) and conveys the replica of the data resource over the WAN (29) to the proxy receiver (48), which serves the replica of the data resource from the proxy receiver (48) to the client (28) over the second LAN (21b).
