Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a flowchart of a server peak shifting power-on method according to an embodiment of the present invention, which is applicable to performing peak shifting power-on a server according to level states of different power signals when a power supply is powered on. As shown in fig. 1, the method includes:
and S110, responding to the power-on operation, and monitoring the level states of the first power supply signal and the second power supply signal.
The level states of the first and second power signals transition based on a power-on operation, and the level transitions of the first and second power signals have a time difference. The level states of the first power supply signal and the second power supply signal may each include a high level state and a low level state.
For example, after the server is powered on, the first power signal jumps from low level to high level first, and after a period of time, the second power signal jumps from low level to high level. In a specific example, the first power signal is the voltage stabilization signal PGD _ P3V3_ STBY, and the second power signal is the standby voltage signal PGD _ P0_ VDDCR _ SOC _ S5.
In the embodiment of the present invention, after the server is powered on, a Complex Programmable Logic Device (CPLD) starts to continuously monitor the level states of the first power signal and the second power signal. Specifically, the CPLD periodically obtains the level states of the first power supply signal and the second power supply signal according to the internal clock.
In a specific example, where the internal clock frequency of the CPLD is 8M, then 125ns per clock cycle, the CPLD may acquire the level states of the first and second power signals on the rising edge of each clock cycle.
And S120, determining the corresponding starting time delay of the current server according to the jump time difference of the level state between the first power supply signal and the second power supply signal.
The boot time delay is used as a basis for performing delayed boot of the server, for example, if the boot time delay corresponding to a certain server is 5s, the server is booted after delaying for 5s after receiving the boot instruction. The startup time delays corresponding to different servers in the same machine room are different, and the startup of each server is controlled based on the startup time delays, so that peak-staggering power-up can be realized.
In the embodiment of the invention, after the server is powered ON and enters the AC ON state (the state of inserting the 220V power line), the CPLD starts to continuously acquire the level states of the first power signal and the second power signal. The first level signal and the second level signal jump after the server is powered on, and the jump time is different. The starting-up time delay corresponding to the current server can be determined according to the jump time difference of the level state between the first level signal and the second level signal. Specifically, the startup delay may be calculated by a preset linear or nonlinear algorithm according to the jump time difference, the jump time difference between the first level signal and the second level signal may be counted by an internal clock of the CPLD, and the startup delay of the current server may be determined according to a counting result.
Because the mainboard components of different servers have slight differences due to factors such as production process, the jump time difference between the first level signal and the second level signal of each server mainboard is different. Different starting time delays can be determined for different servers according to different jump time differences, and therefore peak staggering power-on of the servers is achieved.
In addition, at present, a way that the server uses the CPLD for timing control is widely used, and the first power signal and the second power signal are both common signals when the server AC is powered on. According to the scheme, the CPLD uses the first power supply signal and the second power supply signal to generate the starting time delay corresponding to each server, and off-peak power-up under the condition that the existing hardware design is not changed is achieved.
In a specific example, the first power signal is a voltage stabilization signal PGD _ P3V3_ STBY, the second power signal is a standby voltage signal PGD _ P0_ VDDCR _ SOC _ S5, the first power signal jumps from a low level state to a high level state after the server is powered on, and the second power signal jumps from the low level state to the high level state after a period of time. After the server is powered on, the CPLD starts monitoring the level states of the first power supply signal and the second power supply signal, and specifically, the CPLD acquires the level states of the first power supply signal and the second power supply signal at each clock rising edge according to the internal clock. And when the first power supply signal jumps to a high level state and the second power supply signal still keeps a low level state before power-on, starting to accumulate the count value until the second power supply signal also jumps to the high level state, stopping accumulation, and taking the current count value as a random value corresponding to the current server. And finally, calculating to obtain the corresponding starting time delay of the current server according to the random numerical value.
And S130, controlling the off-peak power-up of the current server according to the starting time delay.
In the embodiment of the invention, after the startup delay of the current server is determined, the CPLD can control the off-peak power-up of the current server according to the startup delay. Specifically, after the server receives the power-on command, the CPU of the server controls the power control signal CPU1_ SLP _ S5# to jump from the low level to the high level. The CPLD starts timing when monitoring that the Power control signal jumps to high level, and sends a Power supply starting signal to a Power Supply Unit (PSU) after the timing reaches a startup delay corresponding to the current server, so as to realize off-peak Power-up of the server.
The power-on command may be initiated by the user by pressing a power button of the server or sending a power-on command through the remote device, or may be initiated according to a timing power-on command of the user, which is not specifically limited herein.
According to the technical scheme of the embodiment of the invention, the level states of the first power supply signal and the second power supply signal are monitored in response to power-on operation, the starting time delay corresponding to the current server is determined according to the jump time difference of the level states between the first power supply signal and the second power supply signal, the off-peak power-on of the current server is controlled according to the starting time delay, the starting time delay is determined according to the level states of different power supply signals when the power supply is switched on, the off-peak power-on of the server is realized, no additional hardware equipment is needed, and the low-cost off-peak power-on of the server is realized.
Fig. 2 is a flowchart of a peak-staggered power-on method for a server according to an embodiment of the present invention, which is further detailed based on the foregoing embodiment and provides specific steps for determining a power-on delay corresponding to a current server according to level states of a first power signal and a second power signal. As shown in fig. 2, the method includes:
and S210, monitoring the level states of the first power supply signal and the second power supply signal in response to the power-on operation.
And S220, determining a random value corresponding to the current server according to the jump time difference of the level state between the first power supply signal and the second power supply signal.
In the embodiment of the invention, the CPLD can acquire the jump time difference of the level states between the first power supply signal and the second power supply signal by monitoring the level states of the first power supply signal and the second power supply signal, and further determine the random value corresponding to the current server through the jump time difference. Specifically, the CPLD may determine the random value corresponding to the current server according to a correspondence between the jump time difference and the random value. The CPLD can also acquire a first power supply signal and a second power supply signal at the rising edge of each clock cycle, and under the condition that the first power supply signal is monitored to jump and the second power supply signal is not jumped, the CPLD starts to accumulate the count value until the second power supply signal also jumps, stops accumulating and takes the current count value as a random value corresponding to the current server.
In a specific example, after the server is powered on, the CPLD starts to monitor the level states of the first power supply signal and the second power supply signal, and specifically, the CPLD acquires the level states of the first power supply signal and the second power supply signal at each clock rising edge according to the internal clock. And when the first power supply signal jumps to a high level state and the second power supply signal still keeps a low level state before power-on, starting to accumulate the count value until the second power supply signal also jumps to the high level state, stopping accumulation, and taking the current count value as a random value corresponding to the current server. The first level signal and the second level signal jump after the server is powered on, and the jump time is different.
Optionally, determining a random value corresponding to the current server according to a jump time difference of a level state between the first power signal and the second power signal, including:
at the set time of each clock period, if the first power supply signal is in a high level state and the second power supply signal is in a low level state, accumulating the count value; the set time is the rising edge or the falling edge of the clock;
and if the first power supply signal and the second power supply signal are both in a high level state, stopping the operation of accumulating the count value, and taking the current count value as a random numerical value corresponding to the current server.
In this optional embodiment, a specific manner for determining a random number corresponding to a current server according to a transition time difference of a level state between a first power signal and a second power signal is provided: at the set time of each clock cycle, if the first power supply signal jumps to a high level signal and the second power supply signal continues to keep a low level state, the initial count value is accumulated. And repeatedly executing the operation until the second power supply signal is monitored to jump to a high level state, stopping the operation of accumulating the count value, and taking the current count value as a random value corresponding to the current server.
In one specific example, on the rising edge of each clock cycle, if the first power supply signal jumps to a high signal and the second power supply signal continues to remain in a low state, the initial count value is accumulated. And repeatedly executing the operation until the second power supply signal is monitored to jump to a high level state, stopping the operation of accumulating the count value, and taking the current count value as a random numerical value corresponding to the current server. Similarly, the counting operation may be performed at the falling edge of each clock cycle to obtain a random value corresponding to the current server.
And S230, determining the starting time delay corresponding to the current server according to the random numerical value.
In the embodiment of the invention, after the random value corresponding to the current server is determined, the starting time delay corresponding to the current server is determined according to the random value. Specifically, the random values are stored in a binary form, a value with a set bit number can be selected from the random values as a target value, and decimal data obtained by converting the target value is directly used as the starting time delay.
Optionally, determining the startup delay corresponding to the current server according to the random value includes:
determining the effective digit of the starting-up time delay according to the allowable starting-up time delay range;
and taking the lowest bit of the random numerical value as a starting point, obtaining target data of the significant digits in the random numerical value in a reverse order, and taking the target data as the starting time delay corresponding to the current server.
In this optional embodiment, a specific manner for determining the boot time delay corresponding to the current server according to the random value is provided: first, the significant bit number of the boot delay is determined according to the allowed boot delay range, for example, if the allowed boot delay range is 0-127s, the significant bit number of the binary system is 7 bits. Further, the lowest bit of the binary random number value is used as a starting point, the target data of the significant digits are obtained in the random number value in a reverse order, and the target data is used as the starting time delay corresponding to the current server. The starting time delay effective digit can be flexibly controlled according to the allowable starting time delay range, so that the starting time delays of the servers are inconsistent, off-peak power-up is realized, the starting time delay of each server is ensured not to exceed the allowable starting time delay range, and the influence on the normal work of the servers due to overlong starting time delay is avoided.
In a specific example, the calculated random value is represented as 1111001110 in a binary form, and according to the allowable startup delay range of 0-127s, the significant bit of the startup delay is 7 bits, and at this time, the target data of the next 7 bits may be selected from the random values as the startup delay corresponding to the current server, that is, 1001110 is selected as the target data, and the target data is converted into a decimal system, so as to obtain the startup delay of the server.
