Patent ID: 11449398

Abstract:
Techniques for providing an embedded container-based control plane for clustered environments. A clustered storage system includes one to many storage appliances, in which one storage appliance is designated as a “primary appliance” and any other storage appliance(s) is/are designated as a “peer appliance(s).” The primary appliance includes a central database, one peer appliance includes a synchronously replicated database, and any other peer appliances each include an asynchronously replicated database. The primary appliance further includes a global management IP for managing access to the central database. The primary and peer appliances each further include a control plane container for implementing command processing services. The control plane container of the primary appliance further implements command orchestration services. The clustered storage system with central and replicated databases and a distributed control plane avoids the need to re-synchronize data at the time of storage appliance failure and improves scalability.
