Abstract: A method is used in managing disk drive power saving in data storage systems. Multiple data storage systems storage elements capable of operating in a power saving mode are identified and grouped into a RAID group. One or more logical units are created from the RAID group. The one or more logical units are exposed to a server. The one or more logical units are associated to an application at the server. Power saving settings are determined. A power saving mode based on the power saving settings is enabled.

Abstract: Described are techniques for displaying data. A first set of data is received that includes a first plurality of objects at a first level in a hierarchy. At least some of the first plurality of objects are displayed on a user interface display. A first object is selected from the at least some of the first plurality of objects displayed on the user interface display. Responsive to selecting the first object, a second set of data is received that includes a second plurality of objects at a second level in the hierarchy. At least some of the second plurality of objects are displayed on the user interface display. The user interface display provides infinite scrolling of the first plurality of objects in a first portion of the user interface display and infinite scrolling of the second plurality of objects in a second portion of the user interface display.
