Abstract: Techniques for managing data mobility domains in storage system environments. The techniques employ a multiple master approach, in which each storage system in a storage system domain can function as an owner of the domain. Each domain owner has privileges pertaining to addition of new members to the domain, removal of members from the domain, and modification of domain credentials. When a new storage system is added as a member of the domain, the domain credentials are provided from the domain owner to the new storage system, resulting in the domain credentials being shared among all members of the domain. Domain membership information is also shared among all members of the domain. In this way, the management of storage system domains can be achieved without the need of a domain management server, avoiding a single point of failure or latency and reducing the complexity/cost associated with the domain management server.

Abstract: A data protection technique involves, based on a first set of policies on a first storage array, generating a second set of policies on a second storage array to track the first set. The first array maintains a first storage object, and the second array maintains a second storage object as a replica of the first storage object. The technique further includes detecting assignment of the first set of policies to the first storage object and, in response to such detection, assigning the second set of policies to the second storage object. Application of a set of storage policies to a storage object may be delayed if the storage object is a replication destination. A policy group may identify multiple data protection rules or policies, which may include a snapshot rule and/or replication rule, and a user may be prevented from directly making a rule modification to a policy group. An orphan policy group cleanup operation may be performed to delete orphan policy groups.

Abstract: A technique utilizes a group of data protection policies within data storage equipment. The technique involves providing, by the data storage equipment, access to individually invocable data protection services. The data storage equipment is constructed and arranged to invoke each individually invocable data protection service in response to user entrance of a respective data protection rule to protect data within a storage object. The technique further involves forming, by the data storage equipment, a policy group from multiple data protection rules. The technique further involves assigning, by the data storage equipment, the policy group to a set of storage objects to protect data within the set of storage objects. Such a technique enables assignment of multiple and different data protection rules to a storage object all at once. Moreover, if the policy group is modified, the modification may be applied to all storage objects at the same time.

Abstract: A data protection technique involves, based on a first set of policies on a first array, generating a second set of policies on a second array to track the first set. The first array maintains a first storage object, and the second array maintains a second storage object as a replica of the first storage object. The technique further includes detecting assignment of the first set to the first storage object. The first array provides data protection to the first storage object in accordance with the first set in response to assignment of the first set to the first storage object. The technique further includes, in response to such detection, assigning the second set to the second storage object. The second array provides data protection to the second storage object in accordance with the second set in response to assignment of the second set to the second storage object.
