Abstract: Example implementations relate to a rolling interface object. An example includes causing display, on a display device, of a plurality of data sets in respective display segments of a three-dimensional rolling interface object. At least some of the data sets include dynamic data. The display segments are arranged lengthwise on a surface of the rolling interface object. A primary segment of the display segments is in a foreground position, and background segments of the display segments are adjacent to the primary segment and visually diminished relative to the primary segment. Responsive to a command to roll the rolling interface object, the rolling interface object is changed as to which of the plurality of display segments is the primary segment.

Abstract: An exemplary embodiment of the present invention provides a method of migrating a virtual machine. The method comprises replicating a source storage device corresponding to the virtual machine to a target storage device through replication links. The method also comprises receiving a migration state that indicates initiation of a migration of the virtual machine from a source server to a target server. The method also comprises collecting storage system status information of the source storage device and storing the storage system status information to a persistent store accessible to the target server. The method also comprises sending memory states and central processing unit (CPU) states to the target server through a communications network. The method also comprises performing a failover of the virtual machine from the source server to the target server and from source storage device to target storage device.

Abstract: A storage system comprising apparatus for consolidating portions of free space from a plurality of remote storage units; and apparatus for presenting the consolidated portions as a single file system.

Abstract: A method includes identifying with a server a first range of data blocks in a storage device array corresponding to data files selected for replication, the first range of data blocks being managed by a source host device; mapping the first range of data blocks to a second range of data blocks in the storage device array managed by the destination host device; copying the data blocks from the first range that contain the data files selected for replication to the corresponding data blocks in the second range; deleting files in the copied data blocks of the second range that have not been selected for replication; and condensing the second range of data blocks.
