Abstract
A LUN is provided that can store multiple datasets (e.g., data and/or applications, such as virtual machines stored as virtual hard drives). The LUN is partitioned into multiple partitions. One or more datasets may be stored in each partition. As a result, multiple datasets can be accessed through a single LUN, rather than through a number of LUNs proportional to the number of datasets. Furthermore, the datasets stored in the LUN may be pivoted. A second LUN may be generated that is dedicated to storing a dataset of the multiple datasets stored in the first LUN. The dataset is copied to the second LUN, and the second LUN is exposed to a host computer to enable the host computer to interact with the dataset. Still further, the dataset may be pivoted from the second LUN back to a partition of the first LUN.
