Dynamically Expanding Storage Capacity of a Storage Volume

摘要

A storage system includes at least one storage device on which are provided data storage volumes and an extended storage volume. The data storage volumes include a first data storage volume that is implemented with a data protection mechanism, and a second data storage volume that is implemented without the data protection mechanism. Also, an extended storage volume is provided that is initially un-allocated to any of the data storage volumes. A controller dynamically allocates at least one portion of the extended storage volume to the particular data storage volume to dynamically expand storage capacity of the particular data storage volume.
