Abstract:
A method and system for providing an improved compliance clock service are described. An example method comprises establishing a system compliance clock (SCC) for a storage system that provides a compliant storage service, and establishing, for a volume in the storage system, a volume compliance clock (VCC). A current value of the SCC may be periodically updated based on hardware ticks monitored at the associated storage node. The volume compliance clock is to update its value based on a current value of the SCC.
Abstract:
A system and method for avoiding object identifier collisions in a cluster environment is provided. Upon creation of the cluster, volume location databases negotiate ranges for data set identifiers (DSIDs) between a first site and a second site of the cluster. Any pre-existing objects are remapped into an object identifier range associated with the particular site hosting the object.
