Abstract: Embodiments for disaster recovery (DR) configuration management. An orchestration mechanism is used to automate a deployment and/or a configuring of two or more storage clusters for DR by arranging, in one step, a mirroring session between the two or more storage clusters. The two or more storage clusters are existing clusters, and the orchestration mechanism locates each of the existing storage clusters and establishes the mirroring session between the two.

Abstract: A computer-implemented method according to one aspect includes determining whether an operating system of a node of a distributed computing environment is functioning correctly by sending a first management query to the node; in response to determining that the operating system of the node is not functioning correctly, determining whether the node has an active communication link by sending a second management query to ports associated with the node; and in response to determining that the node has an active communication link, resetting the active communication link for the node by sending a reset request to the ports associated with the node.

Abstract: Methods that can boot a target computing device and/or target computing system from a checkpoint image for the target computing device and/or target computing system generated at a source computing system are disclosed herein. One method includes generating, by a processor on a source computing system, a checkpoint image for a target computing device and distributing the checkpoint image from the source computing system to the target computing device. Here, the checkpoint image is stored in the host computing system and is configured to enable the target computing device to restore itself from the checkpoint image and the source computing system and the target computing device are separate computing entities. Apparatus, systems, and computer program products that can include, perform, and/or implement the methods are also disclosed herein.

Abstract: A method, system, and computer program product for file system synchronization-based updating is provided. The method identifies an update request associated with a software update. Based on the update request, the method modifies one or more data object on a synchronization array. The modification to the data object corresponds to the software update of the update request. The method validates the modification to the one or more data objects to ensure a match between elements of the synchronization array. A persistent RAM state is established for an element of the synchronization array. The method initiates a reboot to complete the update request. The reboot applies the software update to one or more elements of the synchronization array.

Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include initializing multiple computing nodes to execute one or more software applications that provide a computing service, each of the computing nodes having a respective set of configuration data. Examples of the services include storage services, computational services and web service. Subsequent to deploying the multiple computing nodes as a software defined computing (SDC) cluster, an additional computing node is initialized using a given set of configuration data, and the additional computing node is added to the SDC cluster. In some embodiments, the additional node can be initialized and added to the SDC cluster in response to detecting a condition in the SDC cluster. In alternative embodiments, the additional node can be initialized and added to the SDC cluster in response to receiving a request to add an additional service to the SDC cluster.
