A cooling system for an information handling system includes multiple compressors, and a processor programmed to identify a first compressor in a compressor array. The identifying is performed in response to a determination that a change in the operation of a cooling system associated with the IHS is needed to maintain a temperature set point. Further, the cooling system includes the compressor array. The processor is also programmed to making a first determination that the first compressor in the compressor array is unavailable. Then, based on the first determination, identify a second compressor in the compressor array, make a second determination that the second compressor is available, and adjust an operation of the second compressor to implement the change.

System and method for environmental condition management

A method for removing moisture from an airflow via a cooling system includes identifying a plurality of active cooling circuits in the cooling system. The method also includes lowering a first temperature set point of a first cooling circuit of the multiple cooling circuits. In addition, the method includes raising a second temperature set point of a second cooling circuit of the multiple cooling circuits.

System and method for adjusting environmental conditions

A method for managing environmental conditions of an information handling system includes obtaining an ambient temperature and an ambient humidity of an environment proximate to the information handling system. The method also includes determining a target relative humidity for the information handling system and determining a target temperature for the information handling system based on the target relative humidity, the ambient temperature, and the ambient humidity. Further, the method includes determining that the target temperature is within an acceptable range of temperatures. In addition, the method includes adjusting an amount of air recirculated through the information handling system, and adjusting the amount of air recirculated is based on the determination that the target temperature is within an acceptable range of temperatures.

An information handling system includes multiple components and multiple zones, with each zone including a portion of a total number of the components. The information handling system also includes a processor programmed to determine that a communication failure has occurred with one of the components of the information handling system, identify a zone of the multiple zones that includes the one of the components; and instruct the zone to switch to a default mode.

System and method for environmental control

An automated refrigerant recharging system determines whether a cooling load parameter of a direct expansion (DX) cooling system that cools information technology (IT) modules of an information handling system (IHS) has reached a defined recharging threshold that results in a response of the pressure value for measurement by the pressure transducer. In response to the cooling load parameter being equal to or greater than the defined recharging threshold, a controller determines whether a pressure value of the refrigerant of the DX cooling system is less than a defined target pressure value corresponding to the defined recharging threshold. In response to determining that the pressure value of the refrigerant of the DX cooling system is less than the defined target pressure value, the controller autonomously opens a control valve to transfer refrigerant to the DX cooling system.

A cooling system, large-scale information handling system (LIHS), and method avoid vapor condensation in information technology (IT) modules by operating all air handling units (AHU) in the same mode of operation. An AHU supervisory controller of the cooling system determines whether a trigger condition exists that indicates a risk of vapor condensation in the at least one IT module within LIHS that is cooled by more than one AHU. Each AHU directs the intake of cooling air in a selected mode of operation from among: (i) an outside air mode; and (ii) a mechanically cooled air mode. In response to determining that the trigger condition exists, the AHU supervisory controller triggers all AHUs to operate in a mode of operation selected to avoid condensation.

Multimode cooling control of air handling units to prevent condensation

Cooling system of modular data center (MDC) has air handling unit (AHU) that circulates cooling air through information technology (IT) module(s). Transducer(s) sense first air characteristic value of cooling air directed to IT module(s) of MDC, the value being selected one of: (i) temperature value; and (ii) humidity value. AHU controller determines whether first air characteristic value satisfies first air characteristic criterion of one of: (i) a temperature value equal to or greater than minimum temperature threshold; and (ii) a humidity value equal to or less than maximum humidity threshold. In response to determining that first air characteristic criterion is not satisfied, AHU controller triggers supplemental heater to warm cooling air before cooling air comes into contact with IT module(s) inside of MDC to at least one of: (i) provide cooling air above minimum operating temperature of components within IT module(s); and (ii) prevent condensation.

An interactive component-level visual monitoring and control (ICVMC) system of a large-scale information handling system (LIHS) displays on a display device graphical user interfaces (GUIs) that include a visual representation of data centers (DCs) each having functional components operationally configured and interconnected in a system that operates based, at least in part, on one or more set points stored in respective registers. in response to receiving a user selection, ICVMC system changes set point/s respectively in registers in at least one DC based upon a test protocol or a locally-optimized operating protocol to obtain one of a test result and a local optimization of the at least one DC.

Floating set points to optimize power allocation and use in data center

A controller of a large-scale information handling system (LIHS) includes a memory containing visual representations of architecture and sub-architecture associated with respective data center (DC) configurations. An interactive component-level visual monitoring and control (ICVMC) system includes a processor in communication with the component level monitors and the memory and includes an ICVMC module executing on the processor to receive identification information from one or more component-level monitors of a DC. The DC includes-functional components operationally configured and interconnected in a core architecture in a first DC configuration and monitored respectively by the one or more component-level monitors. The ICVMC module determines the first DC configuration and associated core architecture based on the received identification information. The ICVMC module generates graphical user interfaces (GUIs) for the DC based on the determined first DC configuration and the visual representation of architecture and sub-architectures associated with the first DC configuration.
