Detailed Description
The core of the application is to provide a method and a system for preventing the spare power module from being over-discharged when a storage system is powered down and a fan is hung up, and the storage system, wherein the spare power module can be prevented from being over-discharged when the storage system is powered down.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The execution main body of the embodiment can be a management chip, namely, an abnormal power failure process of the storage system is managed; referring to fig. 1 in particular, fig. 1 is a flowchart of a method for preventing a standby power module from being overdischarged when a power-down fan of a storage system is hung up according to an embodiment of the present application; the method can comprise the following steps:
s110, when the storage system is abnormally powered off, monitoring whether the fan state is a hang-up state;
specifically, when the storage system is abnormally powered off, the fan state monitoring program is triggered to monitor whether the fan state is a hang-up state. The specific mode of monitoring the fan status is not limited in this embodiment, as long as it can know whether the fan is hung up in time. The monitoring of the fan-out state can be carried out, for example, by an anti-fan-out circuit designed on the fan control circuit part.
S120, if the fan is not in the hang-up state, executing a normal fan control strategy;
specifically, the present embodiment does not limit the specific content of the specific normal fan control strategy.
S130, if the state is a hang-up state, monitoring whether the temperature of the storage system exceeds a set temperature or not according to a monitoring period;
specifically, the present embodiment does not limit the specific monitoring period, and for example, the monitoring may be performed in real time, or may be performed in a period of 20 milliseconds. The user can set and modify according to actual requirements.
The present embodiment may monitor the overall temperature of the storage system, or the temperature of the key portions of the storage system, and further, when monitoring the temperature of the key portions of the storage system, the corresponding temperature value may be set according to the actual condition of each key portion to determine whether the key portion is over-temperature. This is corresponding, it may be that the storage system does not exceed the set temperature only when the temperature of each key part is lower than the corresponding set temperature, or it may be that the storage system does not exceed the set temperature when the proportion of the temperature of the key part lower than the corresponding set temperature exceeds a certain value. This embodiment is not limited to the above. Preferably, monitoring whether the temperature of the storage system exceeds a set temperature may include:
monitoring whether the temperature of a preset key position point of the storage system exceeds a set temperature.
Specifically, the preset key location point is not limited in this embodiment, and the user may set and modify the key location point according to the actual situation. For example, the temperature sensitive components may all be set to preset critical location points.
S140, if the voltage exceeds the preset value, turning on a fan power supply;
and S150, if the voltage is not exceeded, turning off the power supply of the fan.
Specifically, when the temperature of the storage system does not exceed the set temperature, it is proved that the temperature of the storage system is normal and does not need the full-load operation of the fan, and at the moment, in order to prevent the phenomenon that the standby power module is overdischarged when the storage system is powered down, the power supply of the fan is turned off. When the temperature of the storage system exceeds the set temperature, the temperature of the storage system is proved to be normal and the fan needs to operate, and the power supply of the fan needs to be switched on and off. However, in order to prevent the spare power module from overdischarging when the storage system is powered down, the embodiment preferably monitors whether the temperature of the storage system exceeds the set temperature periodically; this allows the fan power to be turned off immediately when the storage system temperature decreases in time.
Based on the technical scheme, the method for preventing the spare power module from being overdischarged when the storage system is powered down and the fan is hung dead comprises the steps of confirming whether the fan is hung dead or not by monitoring the state of the fan, confirming whether the temperature of the storage system is over-temperature or not by monitoring the temperature of the storage system, and carrying out corresponding switch control on a fan power supply according to a monitoring result, namely, closing the fan when the fan is hung dead and the temperature of the storage system is lower so as to prevent the spare power module from being overdischarged when the storage system is powered down.
Based on the above embodiment, in order to more reasonably prevent the storage system from being overdischarged when the power failure occurs on the basis of not affecting the performance of the storage system, in this embodiment, after monitoring that the fan state is the hang-up state, and before monitoring whether the temperature of the storage system exceeds the set temperature, the method further includes:
the fan power is immediately turned off.
Specifically, at this time, when the step S130 is not executed, the power supply of the fan is already turned off, so that the situation of overdischarge of the standby power module can be prevented first, and then the step S130 is executed, which improves the effect of the method.
Further, whether the power-down process of the storage system is finished or not can be monitored before the power supply of the fan is immediately turned off; if not, the power supply of the fan is immediately turned off. If so, subsequent steps may not be necessary to improve system efficiency.
Still further, in the process of periodically monitoring the temperature of the storage system, before the switching of the power supply of the fan is required each time the temperature of the storage system exceeds the set temperature: monitoring whether the power failure process of the storage system is finished or not; if the power failure process is not finished, the fan power supply is turned on, and if the power failure process is finished, the power failure process can be directly finished without turning on the fan power supply.
Specifically referring to fig. 2, the method determines whether the fan is dead hung by monitoring the fan state, monitors the temperature of the storage system at the same time, determines whether the system is over-temperature, and then performs corresponding switching on and off control on the fan power supply in cooperation with the fan power supply control circuit to control the dead-hung fan, i.e., the fan, so as to prevent the over-discharge of the standby power module. The specific process is as follows:
firstly, in the design process of a fan hardware circuit, a fan control circuit part needs to be designed into an anti-hang circuit, meanwhile, a power supply of the fan is designed into a controllable on-off design, and a control Pin Pin is introduced into a management chip for control;
secondly, in the design of a management chip, a fan hang-up processing process in a power failure process is added, namely when the storage system is abnormally powered down, a program in the management chip executes an abnormal power failure fan management program and monitors whether a system fan is hung up or not; the fan is turned on and off by monitoring the key temperature point of the system in the power failure process of the system, so that the energy-saving effect is achieved, and the over-discharge of the standby power module is prevented. The method adopts the mode of matching the fan control software program with the hardware circuit, realizes the technology of preventing the spare power module from over-discharging when the fan is hung dead in the power failure process of the storage system, prevents the user data from being lost in the power failure process, and further improves the reliability of the storage system.
Based on the technical scheme, the method for preventing the spare power module from being overdischarged when the storage system is powered down and the fan is hung dead comprises the steps of confirming whether the fan is hung dead or not by monitoring the state of the fan, confirming whether the temperature of the storage system is over-temperature or not by monitoring the temperature of the storage system, and carrying out corresponding switch control on a fan power supply according to a monitoring result, namely, closing the fan when the fan is hung dead and the temperature of the storage system is lower so as to prevent the spare power module from being overdischarged when the storage system is powered down; the loss of user data in the power failure process is prevented, and the reliability of the storage system is further improved.
