Abstract: Tree discovery systems and methods are disclosed. An example of a method is carried out by program code stored on non-transient computer-readable medium and executed by a processor. The method may include identifying in computer-readable medium a first node for a system under consideration, each node in the computer-readable medium representing a characteristic of a component. The method may include selecting at least a second node from the computer-readable medium for the first node. The method may include discovering in the computer-readable medium at least one system tree for the system under consideration based on the first node and the at least second node.

Abstract: A system for multi-stage control of humidity in fluid flow supplied to at least one information technology apparatus includes a sensor, a first stage apparatus configured to vary humidity levels in the fluid flow, and a second stage apparatus positioned downstream of the first stage apparatus along the fluid flow to further vary humidity levels in the fluid flow. The system also includes a controller configured to receive environmental condition information from the sensor, to determine whether the information indicates that the humidity level is outside of a predetermined range, and to manipulate an operation of at least one of the first stage apparatus and the second stage apparatus to vary the humidity level in the fluid flow in response to the information indicating that the humidity level is outside of the predetermined range.

Abstract: In a method of generating governing metrics, a high-level goal to be met in a provisioned system is identified. In addition, a low-level governing policy designed to facilitate achievement of the high-level goal is selected and properties relating to the selected low-level governing policy are identified. The identified properties are formulated to define governing metrics relevant to the selected low-level governing policy and the formulated governing metrics are outputted. The formulated governing metrics are configured to be used in at least one of evaluating and controlling resource provisioning in the provisioned system.

Abstract: Methods and apparatus are provided for use with thermal electric cooling devices (TECDs). An apparatus is mapped so as to identify the heat dissipating entities and zones thereof. A first cooling plan is devised in accordance with the mapping, the cooling plan being dependant upon TECDs. At least one other cooling plan is devised that is distinct from the first cooling plan. The coefficient of performance (COP) for each of the cooling plans is calculated. One of the cooling plans is selected and implemented in accordance with a comparison of the COPs. Precision, zone-oriented cooling is provided, avoiding excessive material scale and wasted energy.
