SCALABLE OBJECT SERVICE DATA AND METADATA OVERFLOW

Technologies support virtual expansion of object containers and of individual large objects in a cluster. Some examples provide scalable object service blob container overflow using multiple clustered shared volumes. One or more of the following may overflow from one cluster volume to another: multiple individual data objects of a container, at least one section of a data object of the container, metadata of at least one object of the container, system metadata of the container. The overflow may be hidden by maintaining a flat namespace outside the cluster.
