A method includes generating, by a processor, an index data structure including allocation of nodes that each represent a computing element of multiple computing elements. In response to determining a change in status of any of the nodes, the method propagates changes in status of any computing element between associated node levels of the index data structure using an application programming interface (API). An updated status of one or more of the nodes is provided based on the change in status.

Discovering and publishing device changes in a cloud environment

One embodiment provides a method, including: generating, for each of a plurality of storage volumes, an actual used storage capacity model and identifying a potential storage capacity savings using the actual used capacity model, wherein each of the plurality of storage volumes has been identified as a candidate for migration to a thin provisioned volume; generating, for each of the plurality of storage volumes, an input/output profile model and identifying a potential change in performance of an application accessing the storage volume using the input/output profile model; generating, for each of the plurality of storage volumes, a growth profile and identifying a potential change in capacity using the growth profile; and determining, using an optimization algorithm, a subset of the plurality of storage volumes to be migrated to thin provisioned volumes based upon the volume capacity model, the performance model, and the volume growth profile.

Identification of volumes for thin provisioning

A method for discovering and publishing device changes in a cloud computing environment. The method includes scanning, by a processor, a computing environment to detect a multiple computing elements. The processor generates an index data structure including allocation of nodes that each represent a computing element of the multiple computing elements. The nodes each include a computed hash value that includes computing element status of the node and status of associated child nodes. The index data structure is monitored for discovering a change in status of any of the nodes. In response to determining a change in status of any of the nodes, the index data structure is re-generated and the hash value for each node associated with the change in status is re-computed. An updated status of one or more of the nodes is provided based on the change in status.

A computer-implemented method for configuring an operating system to associate a peripheral is described. The method includes loading the operating system on a client computer based on an operating system image, determining an identifier of the client computer, retrieving peripheral information to identify a peripheral associated with the client computer, and writing a configuration setting of the client computer to a storage medium of the client computer based on the peripheral information. The identifier identifies the client computer. The peripheral information is associated with the client computer based on an association between the peripheral information and the identifier.
