Abstract: A configuration management system is configured to receive a registration request message from a computing node that includes identifying information, and to select a node pool in response to detection of a match between the identifying information matching a qualification parameter assigned to the node pool. The configuration management system is further configured to select configuration information for the computing node based on an image configuration template associated with the node pool. At least part of the configuration information is selected from a predefined resource pool. The configuration management system is further configured to provide the configuration information to the computing node.

Abstract: Examples described herein include virtualized environments including a virtualized file server. Examples of secure domain join processes are described which may facilitate joining a virtualized file server or portions thereof to a domain. In some examples, the secure domain join process itself, and/or an associated file server virtual machine, may have insufficient credentials to write objects into an active directory. The active directory credentials need not be shared with the file server virtual machine. Rather, in some examples, the secure domain join process may provide a user system with a list of actions to be performed using active directory credentials.

Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor with programmed instructions to receive, from a user device and via a network, encrypted credentials for logging on a user associated with the user device to a virtual machine. The processor is coupled to the virtual machine via a hypervisor. The processor has programmed instructions to decrypt the credentials, send, to an operating system of the virtual machine, the decrypted credentials, and cause the operating system to log the user on to the virtual machine.

Abstract: A system and method include migrating, by a migration controller, a first entity of a first subset of entities from a source site to a target site in a virtual computing system based on an asynchronous mode of replication. The system and method also include replicating, by the migration controller, data of a second entity of a second subset of entities from the source site to the target site based on a synchronous mode of replication in parallel with the migration of the first entity for dynamically adjusting a recovery time objective parameter.

Abstract: Systems and methods for high availability computing systems. Systems and methods include disaster recovery of two-node computing clusters. A method embodiment commences upon identifying a computing cluster having two nodes, the two nodes corresponding to a first node and a second node that each send and receive heartbeat indications periodically while performing storage I/O operations. One or both of the two nodes detect a heartbeat failure between the two nodes, and in response to detecting the heartbeat failure, one or both of the nodes temporarily cease storage I/O operations. A witness node is accessed in an on-demand basis as a result of detecting the heartbeat failure. The witness performs a leadership election operation to provide a leadership lock to only one requestor. The leader then resumes storage I/O operations and performs one or more disaster remediation operations. After remediation, the computing cluster is restored to a configuration having two nodes.

Abstract: Systems and methods for preferential treatment of a prioritized virtual machine during migration of a group of virtual machines from a first virtualized computing environment to a second virtualized computing environment. A data structure is allocated to store virtual machine migration task attributes that are associated with a plurality of in-process virtual machine migration tasks. As migration proceeds, the migration task attributes in the data structure are updated to reflect ongoing migration task scheduling adjustments and ongoing migration task resource allotments. A user interface or other process indicates a request to prioritize migration of a particular one of the to-be-migrated virtual machines. Based on the request, at least some of the virtual machine migration task attributes are modified to indicate a reduced scheduling priority of some of the to-be-migrated virtual machine migration tasks so as to preferentially deliver computing resources to the prioritized virtual machine migration tasks.

Abstract: Methods, systems and computer program products for configuring microservices platforms in one or more computing clusters. In one of the computing clusters, a request to instantiate a microservice platform is received, wherein the request is received in a computing cluster having a first node and a second node, and wherein the first node and second node comprise a first virtualized storage controller and a second virtualized storage controller, respectively. The storage controllers each manage their respective storage pools comprising local storage devices. A first microservice manager is deployed on the first node and a second microservice manager is deployed on the second node.

Abstract: The disclosed systems emulate high-frequency application-consistent snapshots by forming restore point data sets based on remote site replay of I/O commands. A method embodiment commences upon identifying a primary computing site and a secondary computing site, then identifying an application to be restored from the secondary computing site after a disaster. Prior to the disaster, a group of computing entities of the application to be restored from the secondary computing site are identified. Input/output operations that are performed over any of the computing entities at the primary site are streamed to the secondary site where they are stored. An I/O map that associates a time with an indication of a last received I/O command that had been performed over a changing set of computing entities is sent to the secondary site. An agent at the secondary site accesses the I/O map and the streamed-over I/Os to construct recovery data.

Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to detect an operation associated with a first object instance in a first cluster, determine that the first object instance is configured for replication to a second cluster, create an object information (info) metadata entry for the first object instance, create an object replication metadata entry for the first object instance, and simultaneously write the object info metadata entry and the object replication metadata entry to a first data structure and a second data structure, respectively.

Abstract: Systems and methods for workload migration control. Migration control operations commence upon identifying a workload comprising two or more virtual machines to be migrated from a source computing environment to a target computing environment. A migration process initiates migration of the two or more virtual machines to the target computing environment. After the migration process has begun, a user identifies a prioritized virtual machine from among the two or more virtual machines that are in the process of being migrated. In response to receiving the user input, a migration manager suspends progression of selected virtual machines while accelerating progression of the migration of the prioritized virtual machine that is not suspended. The migration of the re-prioritized virtual machine preferentially receives computing resources.

Abstract: In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, and a first virtualized file server configured to receive a request to access a storage item located at a second virtualized file server, determine that the storage item is designated as being accessible by other virtualized file servers, identify an FSVM of the second virtualized file server at which the storage item is located, and forward the request to the FSVM of the second virtualized file server. The storage item may be designated as being accessible by other virtualized file servers when the storage item is associated with a predetermined tag value indicating that the storage item is shared among virtualized file servers. The predetermined tag value may be stored in a sharding map in association with the storage item.

Abstract: Examples described herein include virtualized file servers which may include cloned instances of the virtualized file server. Cloning a virtualized the server may allow for testing of new and/or revised features, disaster recovery plans, or other configurations while maintaining availability of the parent (e.g., source) virtualized file server.

Abstract: Methods, systems and computer program products for computer system data management. A leader node that is in a leader-follower relationship with a follower node is deployed to manage metadata across a plurality of interconnected computing nodes of the computer system. Upon a failure of any sort that results in a loss of operation or a disconnection of the leader node, the followers undertake steps to bring up a new leader. Such steps to bring up a new leader include electing a new leader to replace the lost or disconnected leader and initializing the data state of the new leader node by causing the leader to request incremental snapshots from followers. Additional metadata that might have changed since closing the incremental snapshots can also be retrieved from the followers. The metadata that might have changed since the time of closing the incremental snapshot is subjected to verification using a consensus algorithm.

Abstract: Methods, systems and computer program products for user-specific curation of applications from heterogeneous application sources. Multiple components are interconnected to perform user-specific curation operations. The user-specific curation operations comprise accessing application metadata corresponding to a plurality of applications from a plurality of application sources. The application sources may be heterogeneous and may be situated at local sites or at remote sites. A set of rules are applied to the application metadata to determine if one or more applications are authorized for use by a particular user or group. Publication attributes that control accessibility by a particular user or particular group of users are associated with the authorized applications. Based on the publication attributes as they apply to a particular user, one or more curated applications are selected from the authorized applications.

Abstract: Methods, system, and computer program product for implementing an address translation service that uses nondenominational address handles instead of IP addresses between private cloud domain and public cloud domains. The address translation service can be implemented to enable a data-center running in a private cloud domain to communicate with the public cloud domain data-center over load balancers. In addition, the address translation service ensures that all services that need to communicate across data-centers can be reached over load balancers. As such, to avoid conflicting subnets used by a data center from the private cloud domain and the public cloud domain, services in the public cloud domain use a private cloud load balancer to connect with the services in a private cloud domain. Similarly, a public cloud load balancer is used to connect with services in the private cloud domain.

Abstract: Systems and methods for rebalancing storage-oriented workloads across resources of a distributed data storage facility. Communications are initiated between a client computing device and a plurality of storage target devices of a distributed storage system. The distributed storage system comprises one or more computing nodes that can host virtualized controllers. A client computing device interfaced with the distributed storage system uses an IP address to access an initial virtualized controller. Upon detecting a change event, conditions of the computing environment are analyzed to determine rebalancing options. Analysis of the rebalancing options results in identification of an alternative virtualized controller. A redirect message that identifies the alternative virtualized controller is sent to the computing device. The client computing device connects to the alternative virtualized controller.

Abstract: A system and method include reconfiguring original configuration parameters of virtual objects when restoring the virtual objects on a different node. Snapshots of virtual objects running on a first node can be stored on a second node. Upon failure of the first node, the virtual objects can be restored on the second node based on the snapshots. The snapshots can include configuration information of the virtual objects specifying the resource need of the virtual objects. The second node can determine whether the available resources meet the resource needs of the virtual objects being restored. If the resource needs of the virtual objects exceed the available resources, the second node can reconfigure the original configuration parameters of the virtual objects to ensure the virtual objects can be restored and run on the second node.

Abstract: Examples of distributed database systems are described. Multiple computing nodes may be utilized to provide a distributed database system. Each of the multiple computing nodes may cache a portion of the distributed database. The cache may be utilized to service write requests. A computing node servicing a write request may provide a callback to other computing nodes hosting the distributed database. The local cache may be updated responsive to the write request and callbacks issued to the other computing nodes to allow for updates of other local caches. In this manner, a local cache may be updated prior to updating the distributed database as a whole in some examples. While callbacks may be used to update cached data on other nodes, the computing node servicing the write request may not need to receive a callback prior to updating the local cache.
