Abstract: Various embodiments set forth techniques for maintaining replicas of a data set. The techniques include storing, by a first node, a first replica of the data set on the first node; storing, by a second node, a second replica of the data set on the second node; and performing, by the first node and based on first metadata associated with the first replica, a first data management activity on the first replica that changes a first format of the first replica so that the first format of the first replica is different from a second format of the second replica.

Abstract: One embodiment of the present invention facilitates address resolution protocol (ARP) resolution in an extended subnet. A gateway of a first segment of the extended subnet can determine that a layer-2 address corresponding to a layer-3 destination address of a packet is locally unavailable. The gateway can then determine whether a respective egress interface of an ARP request for the layer-3 destination address is associated with a layer-2 subnet extension from the first segment to a second segment of the extended subnet. The extension can provide a common layer-2 broadcast domain comprising the first and second segments with a same default gateway layer-3 address. If the egress interface is associated with the extension, the gateway can insert a layer-3 address of a first endpoint associated with the extension as a source protocol address in the ARP request. The gateway can send the modified ARP request via the egress interface.

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: A platform-as-a-service infrastructure and application lifecycle manager is configured to implement a common services model to deploy selected services from a common set of services to service domains hosted on multiple different cloud platforms by abstracting dependence on availability of various additional supporting services, such as services that are platform-specific. The platform-as-a-service infrastructure and application lifecycle manager may also manage a lifecycle of available services, such as managing upgrades and/or patches to services.

Abstract: A technique efficiently migrates a live virtual disk (vdisk) across storage containers of a cluster having a plurality of nodes deployed in a virtualization environment. Each node is embodied as a physical computer with hardware resources, such as processor, memory, network and storage resources, that are virtualized to provide support for one or more user virtual machines (UVM) executing on the node. The storage resources include storage devices embodied as a storage pool that is logically segmented into the storage containers configured to store one or more vdisks. The storage containers include a source container having associated storage policies and a destination container having different (new) storage policies.

Abstract: A technique provides efficient data failover by creation and deployment of a protection policy that ensures maintenance of frequent common snapshots between sites of a multi-site data replication environment. A global constraint optimizer executes on a node of a cluster to create the protection policy for deployment among other nodes of clusters at the sites. Constraints such as protection rules (PRs) specifying, e.g., an amount of tolerable data loss are applied to a category of data designated for failover from a primary site over a network to a plurality of (secondary and tertiary) sites typically located at geographically separated distances. The optimizer processes the PRs to compute parameters such as frequency of snapshot generation and replication among the sites, as well as retention of the latest common snapshot maintained at each site to create a recovery point and configuration of the protection policy that reduces network traffic for efficient use of the network among the sites.

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.

Abstract: Examples of systems described herein may allow users to change from an application level disaster recovery system (e.g., an application level replication policy) to a share level disaster recovery system (e.g., a share level replication policy). The change may be made such that a base snapshot need not again be taken when beginning operation under the share level replication policy—rather, the base snapshot previously taken during application level replication may be used in some examples. That base snapshot may be leveraged, an initial set of common share snapshots established, and protection maintained going forward on a share level basis.

Abstract: One embodiment of the present invention provides a system that can manage access to a service from a cluster of computing nodes. An instance of the system can operate on a respective computing node. During operation, the system instance can identify an Internet Protocol (IP) address, which provides access to the service from the cluster of computing nodes to a client device at a client site. The system instance can select the computing node for hosting the IP address in the cluster of computing nodes based on a set of selection criteria. The selection is performed independently at the computing node. The system instance can then assign the IP address to the computing node. The assignment allows a request for the service to be directed to the computing node. Subsequently, the system instance can facilitate the service from the cluster of computing nodes based on the request.
