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.
