摘要： An example operation may include one or more of dividing a data object into a plurality of parts, hashing the data object to generate a hashed data object and hashing the plurality of parts to generate a plurality of hashed parts, generating a plurality of slices where each slice includes the hashed data object and a different respective hashed part, and distributing the plurality of slices across a plurality of blockchain peers, respectively.

摘要： 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.

摘要： 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.

摘要： A method for selecting a leader node among a plurality of network nodes, comprising: providing a current configuration of selected nodes in replicated state machine based system, wherein a first node is set for handling commands received from clients; executing a consensus protocol by the selected nodes under the current configuration; identifying at least one fault indicative event of the first node; calculating a suggested configuration of selected nodes, wherein a second node is set for handling the commands; informing each member of the suggested configuration and the first node of the suggested configuration; executing the consensus protocol in parallel under both the suggested configuration and the current configuration; and when detecting that the first node is faulty, setting the second node for handling the commands under the current configuration in place of the first node and reconfiguring the current configuration to become the suggested configuration.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
