Abstract: High-efficiency cooling is performed in a data center in response to a cooling and/or humidity demand using a system having multiple cooling loops. The system includes a plurality of integrated cooling systems each comprising one or more specifically sized chillers and a liquid loop to address the cooling demand. A free cooling heat exchanger is coupled to the first liquid loop for use when a wet-bulb temperature surrounding the data center is at or below a free cooling set point of the first chilled liquid loop. The system isolates humidity control components to a second chilled liquid loop, and enables greater control of the first chilled liquid loop of the data center to meet specific IT loads.

Abstract: In a method for controlling physical access to a computing device a first access request to a room containing the computing device is received. In response, a processor determines that the first access request is valid based on the room and the date and time of the first access request and unlocks a door to the room to permit entry to the room. Subsequently, a second access request to a cabinet that is located in the room and contains the computing device is received. In response, a processor determines that the second access request is valid based on the cabinet and the date and time of the second access request and unlocks the cabinet to permit access to the computing device.

Abstract: An apparatus for a multi-directional display that includes a first surface situated in an electronic equipment cabinet, wherein the first surface is capable of extending out of at least two sides of the electronic equipment cabinet. A first electronic display is mechanically coupled to a first mount, such that the first electronic display is capable of rotating independently from the first mount. The first mount is coupled to the first surface, such that the first electronic display is viewable when the first surface is separately extended out of the at least two sides.

Abstract: Techniques are described for scheduling received tasks in a data center in a manner that accounts for operating costs of the data center. Embodiments of the invention generally include comparing cost-saving methods of scheduling a task to the operating parameters of completing a task—e.g., a maximum amount of time allotted to complete a task. If the task can be scheduled to reduce operating costs (e.g., rescheduled to a time when power is cheaper) and still be performed within the operating parameters, then that cost-saving method is used to create a workload plan to implement the task. In another embodiment, several cost-saving methods are compared to determine the most profitable.

Abstract: Techniques are described for controlling the climate in a data center. Using the input of an administrator, multiple desired attributes of a data center (e.g., temperature, energy consumption, costs, or system performance) may be balanced using a utility function that maximizes the utility of the computing systems in the data center according to the administrator's preferences. Additionally, a cooling model is generated that represents the affect of a control parameter (e.g., the fan speed of a CRAC) on the desire attributes of the data center. The cooling model may then be substituted into the utility function to replace the desired attributes. Using this new utility function, the control parameters may be varied such that the maximum utility is achieved.
