Computing system with power requirement evaluation

A portable personal computer, comprising:

• recording media relative to which input/output (I/O) operations are executable;
• a power source by which a quantity of power is made available for the executions of the I/O operations;
• and
• a processor, disposed in signal communication with the recording media and the power source, which is configured to execute the I/O operations, to evaluate power requirements associated with executions of the I/O operations relative to each individual recording medium and to read the quantity of available power, the processor including:
• a computer-readable medium having a set of instructions stored thereon, which, when executed, cause the processor to refuse the executions of the I/O operations relative to each individual recording medium in accordance with the quantity of available power provided by the power source for the I/O operations being determined to be insufficient at the power source to complete the I/O operations at each individual recording medium relative to the respective evaluated power requirements of each individual recording medium.

A non-transitory computer readable medium having instructions stored thereon, which, when executed cause a processor of a computing system, including recording media, to execute a method of controlling the computing system, the method comprising:

• instantiating input/output (I/O) operations;
• interrogating a power source for a reading of a quantity of available power at the power source;
• reading power requirements for executions of the I/O operations with respect to the recording media;
• determining whether the read quantity of the available power at the power source is insufficient for completing the executions of the I/O operations relative to the respective evaluated power requirements of each individual recording medium;
• and
• refusing the executions of the I/O operations relative to each individual recording medium in accordance with the read quantity of available power at the power source for the I/O operations being determined to be insufficient for completing the I/O operations at each individual recording medium relative to the respective evaluated power requirements of each individual recording medium.

A computing system for assuring completion of I/O operations when power available to the system is deteriorating, the system comprising:

• a processor configured to communicate with recording media, the processor configured to perform a method comprising:
• in a first stage of operation, receiving, by the processor, requests to execute I/O operations, executing requested I/O operations to each recording medium of said recording media and determining power consumption associated with executions of the I/O operations of each recording medium;
• and
• in a second stage of operation, receiving, by the processor, a request to execute an I/O operation to a respective recording medium;
• interrogating, by the processor, a power source for a reading of a quantity of available power at the power source;
• determining, by the processor, the current amount of available power as a result of the interrogating and determining an amount of power required to complete the I/O operation at the respective recording medium based on the determined power consumption associated with executions of the I/O operations of each recording medium;
• executing the requested I/O operations to the respective recording medium based on the determined amount of power required to complete the I/O operation at the respective recording medium being less than the determined current amount of available power at the power source;
• and
• blocking execution of the requested I/O operation to the respective recording medium based on the determined amount of power required to complete the I/O operation at the respective recording medium being greater than the determined current amount of available power at the power source whereby the current amount of available power at the power source is insufficient to complete the I/O operation at the respective recording medium.
