Abstract: A method and system allow to store and retrieve data values and data structure in a memory of an embedded system, the memory also storing executable code uploaded to the embedded system by a first external system through a first version of a firmware. A serializer is configured to receive from the executable code, sizes of data, corresponding to a number of chunks of the data, together with values of the chunks, to form a series of bytes therewith through concatenation, to calculate a total size of the series of bytes, and to write to the memory, successively the total size and the formed series of bytes. A deserializer is configured to read from the memory, successively a total size and a series of bytes, to deconcatenate the series of bytes into successively sizes of data, corresponding to a number of chunks of the data, together with values of the chunks, and to send the same to the executable code.

Abstract: A method for controlling a cooling system of a rack, the rack comprising a heat generating component. The method comprises receiving, by a controller, at least one first temperature indications indicative of temperature variations of at least one heat transfer fluid circulating in at least one respective liquid channel of the cooling system; receiving, by the controller, at least one second temperature indications indicative of a temperature of an air flow of ambient air within the rack, the air flow being generated by at least one fan of the cooling system; and adjusting, based on the at least one first and second temperature indications, a rotational speed of the at least one fan and a rotational speed of at least one pump configured for causing the at least one heat transfer fluid to flow in at least one respective liquid channel.

The method is executed by a controller operatively connected to the cooling system. The method comprises determining, using a machine learning model executed by the controller, an estimated forthcoming power consumption of the data processing device, the machine learning model being based at least in part on a history of power consumption of the data processing device, determining, using a cooling-control model executed by the controller, at least one control signal for controlling the cooling system, determining the at least one control signal being based at least in part on the estimated forthcoming power consumption from the machine learning model, and controlling, by the controller, the cooling system based on the at least one control signal for controlling the cooling system.

Abstract: A connection between a power distribution unit (PDU) and an electric device is identified by generating a data packet containing an identity of the electric device, transmitting the data packet by varying, on a power line connecting an output socket of the PDU to the electric device, a power level between distinct intensities for transmitting distinct logical values of the data packet, sensing, at the PDU, the power level on the power line, reporting, to an identification module, a socket number of the output socket connected to the power line and successive power level data obtained by sensing the power level on the power line, decoding the identity of the electric device by monitoring the successive power level data reported by the PDU, and storing, in a database, a reference between the identity of the electric device, an identity of the PDU, and the socket number.
