摘要：
A method, system, and apparatus for expanding the storage capacity of a data storage system are provided. According to one method, the physical storage devices that store the data and metadata for one or more logical disks are organized into a container. A logical disk segment is created within the container for each logical disk. When storage capacity is added through the addition of logical disks, a new logical disk segment is added to the end of the container for the new logical disk. When storage capacity is added through the addition of capacity to an existing logical disk, a new logical disk segment is added to the end of the container for the new logical disk segment within the logical disk. The devices within a container may be migrated between server computers or between CPUs with their associated mass storage controllers.
