    Abstract: One or more techniques and/or devices are provided for storage virtual machine relocation (e.g., ownership change) between storage clusters. For example, operational statistics of a first storage cluster and a second storage cluster may be evaluated to identify a set of load balancing metrics. Ownership of one or more storage aggregates and/or one or more storage virtual machines may be changed (e.g., permanently changed for load balancing purposes or temporarily changed for disaster recovery purposes) between the first storage cluster and the second storage cluster utilizing zero-copy ownership change operations based upon the set of load balancing metrics. For example, if the first storage cluster is experiencing a relatively heavier load of client I/O operations and the second storage cluster has available resources, ownership of a storage aggregate and a storage virtual machine may be switched from the first storage cluster to the second storage cluster for load balancing.

    Abstract: The present invention uniquely names storage devices in a global storage environment with hierarchical storage domains. In particular, according to one or more embodiments of the present invention a storage device (e.g., a disk) is connected at a particular location within the global storage environment. That particular location is associated with a path of each of one or more hierarchical storage domains in which the storage device is located. Accordingly, a name is assigned to the storage device that is the path of the hierarchical storage domains in which the storage device is located.

    Abstract: A primary write request that is to modify a primary portion of primary data stored in a primary storage node is received. The primary write request is to be replicated to create a current secondary write request. The current secondary write request is to modify a current secondary portion of secondary data that is stored in a secondary storage node. A current data range of the current secondary portion is determined. A determination is made of whether a previous secondary write request is in process of modifying a previous data range that at least partially overlaps with a current data range of the current secondary portion. Execution of the primary write request is suspended, until the previous secondary write request has completed updating the secondary storage node.

    Abstract: During a storage redundancy giveback from a first node to a second node following a storage redundancy takeover from the second node by the first node, the second node is initialized in part by receiving a node identification indicator from the second node. The node identification indicator is included in a node advertisement message sent by the second node during a giveback wait phase of the storage redundancy giveback. The node identification indicator includes an intra-cluster node connectivity identifier that is used by the first node to determine whether the second node is an intra-cluster takeover partner. In response to determining that the second node is an intra-cluster takeover partner, the first node completes the giveback of storage resources to the second node.

    Abstract: Data consistency and availability can be provided at the granularity of logical storage objects in storage solutions that use storage virtualization in clustered storage environments. To ensure consistency of data across different storage elements, synchronization is performed across the different storage elements. Changes to data are synchronized across storage elements in different clusters by propagating the changes from a primary logical storage object to a secondary logical storage object. To satisfy the strictest RPOs while maintaining performance, change requests are intercepted prior to being sent to a filesystem that hosts the primary logical storage object and propagated to a different managing storage element associated with the secondary logical storage object.

    Abstract translation: 可以在集群存储环境中使用存储虚拟化的存储解决方案中的逻辑存储对象的粒度提供数据一致性和可用性。 为了确保不同存储元件之间的数据的一致性，跨不同存储元件执行同步。 通过将更改从主逻辑存储对象传播到辅助逻辑存储对象，对数据的更改在不同群集中的存储元素之间进行同步。 为了在维护性能的同时满足最严格的RPO，在发送到托管主逻辑存储对象的文件系统之前，更改请求将被拦截，并传播到与辅助逻辑存储对象关联的其他管理存储元素。
