Abstract: Methods, systems and computer program products for implementing high-availability file services in a clustered computing environment. Two or more clusters are interconnected to carry out operations for replication of file content between file servers. The file servers and their respective network links are registered with a file server witness. The file servers operate in synchrony, where each file I/O is replicated from one file server to another file server over a first set of network paths. A file server witness communicates with each file server using a second set of two or more network paths interfaced with respective file servers. The file server witness monitors the file servers to determine operational health of the file servers. Upon receipt of a file I/O request, the file I/O request is directed to one of the two file servers based at least in part on the determined operational health.

Abstract: The present disclosure describes techniques used in systems, methods, and in computer program products to perform incremental hibernate and resume of bare metal clusters. A replication process can generate full/incremental snapshots at the cluster level and at a resource level of the processes of the cluster. In the even that a user instructs the cluster to hibernate some or all processes of the cluster, the process can capture an incremental snapshot of the corresponding resources far more quickly than would be required to generate full snapshots for those resources. Likewise, system configuration information can be captured to enable the underlying infrastructure of the cluster to be restored in the future. In some embodiments, the approach provided herein also implements an instant restore feature.

Abstract: A system and method include receiving, by a database engine of a database system associated with a virtual computing system, a user request via a dashboard for provisioning a source database with the database system, receiving, by the database engine via the dashboard, selection of a database engine type, and receiving, by the database engine via the dashboard, selection of a Service Level Agreement (“SLA”) and a protection schedule. The system and method also include provisioning, by the database engine, the source database based upon the database engine type, creating, by the database engine, an instance of a database protection system based upon the SLA and the protection schedule, including associating the instance of the database protection system with the source database, and displaying, by the database engine, the source database within the dashboard.

Abstract: Methods, systems and computer program products for bringing-up a computing cluster on a public cloud infrastructure with techniques utilizing expressed intents (high level descriptions of desired configuration) and asynchronously receiving configuration status messages from the public cloud infrastructure. The method includes a cloud management computing system transmitting to the public cloud infrastructure a first expressed intent for bringing-up a computing cluster. The cloud management computing system asynchronously receiving periodic status messages comprising cluster status data from the public cloud infrastructure reflecting a current configuration state of the computing cluster. The system determines, based on the cluster status data, whether the first expressed intent for the computing cluster has been achieved.

Abstract: Methods, systems, and computer program products for executing trusted software components in public computing clouds. Verifiably authentic software components are installed into a tenant partition of a multi-tenant public cloud-based environment. To do so, a software component installer is configured to install registered software components into the tenant partition. Installer processing includes (1) obtaining a component-specific token for a software component wherein the component-specific token is specific to both the software component to be installed and a particular tenant, and (2) installing the software component on behalf of the given tenant in the multi-tenant public cloud-based environment. Prior to executing the underlying code of the tenant-specific software component, the software component is authenticated with a component registry using the component-specific token. Additional trusted components are installed based on demand from within the tenant partition.

Abstract: Examples described herein are generally directed towards generating, allocating, and assigning consistent file server user identifiers (IDs) (also described herein as a global identifier (GID)) domains subscribed to by file server(s) within a distributed file server environment. In operation, a virtualized file server of a distributed file server system may scan for and identify a trusted domain subscribed to by the virtualized file server. The virtualized file server may allocate to the trusted domain a range of file server user IDs. The virtualized file server may store a mapping between local user security identifiers (SIDs) in the trusted domain and a respective file server user IDs within the allocated range. The virtualized file server may provide the mapping to a replication target, such as during a replication, migration, and/or a disaster recovery event.

Abstract: A plurality of different virtualization system images are configured for deployment to a plurality of nodes in heterogeneous environments. Individual ones of the virtualization system images are configured such that once deployed, the nodes form a computer cluster having a storage pool that is shared across the nodes. When configuring the virtualization system images, information that describes the heterogeneous computing environments is accessed, and constraints pertaining the heterogeneous computing environments are reconciled in advance of configuring the different virtualization system images. A common subnet across the heterogeneous environments is established. The plurality of different virtualization system images are configured to access the common subnet once deployed. The common subnet serves as a storage I/O communication path over which a cluster-wide storage pool is implemented.

A high availability solution is provided that creates a global file system namespace across two clusters located at separate sites, where a synchronous storage replication is used to support the stretched container, allowing VMs and files stored in the container to be replicated in real-time between the two clusters.

Abstract: A technique provides network efficient data failover by explicitly protecting one or more common snapshot references at sites of a multi-site data replication environment to improve granularity of control of recovery point objectives (RPO) for data across the sites. A common snapshot reference or recovery point (RP) ensures that, in the event of failure to a site, data designated for failover may be quickly protected by replicating only small incremental changes to the RP so as to maintain RPO requirements across the sites. Illustratively, the technique enhances and extends a disaster recovery (DR) application programming interface (API) protocol through an extension that defines and applies a tag to the RP, wherein the tag enables protection and/or preservation of the RP by ensuring that the sites honor the tag applied to the RP. The tag essentially functions as an advisory lock for the RP that is shared among the sites to prevent deletion of the RP at the sites throughout the duration of the lock.

Abstract: Methods, systems, and computer program products for moving a container-based application from a source HCI cluster to a target HCI cluster. An HCI storage cluster data replication mechanism operates to copy data and metadata from a plurality of storage devices that constitute a storage pool of the source HCI cluster. A container-based application replication mechanism operates to copy data and metadata from an executable container that is running on a node of the source HCI cluster. Periodically (1) the state of the container-based application is saved using the container-based application replication mechanism, and (2) the state of the storage cluster data of the HCI storage cluster is saved using the HCI storage cluster data replication mechanism. The saved state of the container-based application including its application data and metadata are combined with the saved state of the storage cluster data to bring-up the container-based application at the target HCI cluster.
