Abstract
Provided are a power supply method and device for a storage array, and a server. The method includes: acquiring state data for representing power supply state of power modules first; determining, according to the state data, whether the storage array reaches a power failure triggering condition; and when the storage array reaches the power failure triggering condition, controlling the current power module to be switched to other power modules or standby batteries.
Claims19
A method for supplying power to a storage array, comprising:
- acquiring state data for representing power supply state of power modules;
- determining, according to the state data, whether the storage array satisfies power failure triggering conditions;
- and
- controlling a current power module to be switched to another power module or a standby battery in response to determining that the storage array satisfies the power failure triggering conditions;
- wherein the acquiring state data for representing power supply state of power modules comprises:
- acquiring power supply data of a power grid, output data of multiple power modules, a control signal for controlling the multiple power modules, temperature data of controllable switches, and driving data for driving the multiple power modules;
- and
- the power failure triggering conditions comprise:
- power supply from the power grid being cut off or a power supply stability threshold of the power grid being smaller than a preset threshold;
- output of the power modules being stopped, output voltages of the power modules not reaching a minimum power supply voltage required by the storage array or exceeding a maximum power supply voltage of the storage array;
- the control signal for controlling the multiple power modules disappearing;
- temperatures of the controllable switches being too high;
- and abnormal driving of the power modules.
