Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification.
The application provides a synchronous flashing method of an indicator light, which is applied to a BMC in a server, and as shown in fig. 1, the method comprises the following steps:
and S100, if the server completes the synchronization of the system time according to the time server, acquiring the synchronized system time.
In the computer room, a plurality of servers may be provided, for example, ten or more servers, and a processor, a logic chip, and a BMC (Board Management Controller) may be provided in the servers. A clock server is installed in the machine room, and the clock server may complete clock synchronization based on NTP (Network Time Protocol) or based on other clock protocols. The following description will take the example where the clock server is an NTP server.
The NTP server acquires clock information from the internet after being connected to the internet, and calibrates the unified time of the NTP server.
In the computer room, the server is powered on and started, and the server can start to work by using a system clock of the server, wherein the system clock is a local clock of the server. After the server is powered on and started, the server starts the indicator lamp to flash according to the first flash period. In order to distinguish from abnormal flicker, the first flicker period can be set for a long time, and one first flicker period is completed in a mode of from dark to light and then from light to dark.
A plurality of servers are arranged in a machine room, even if the same flashing period is set on each server, the power-on starting time of each server is different, and uniform flashing cannot be realized. When one server in the machine room is abnormal and is switched to flicker in the second flicker cycle, the flicker of each server is inconsistent, and a worker can hardly recognize that the server is abnormal.
And then, the server after power-on starting interacts with the NTP server to correct the local time of the server, and the flow of time correction of the server and the NTP server based on the NTP is realized conventionally and is not expanded. In this way, the system clock of the server is synchronized.
A thread may be run in the BMC of the server to obtain the system time of the server. After the server and the NTP server complete time synchronization, a processor in the server may send a notification to the BMC in the form of an interrupt, so that a thread of the BMC is activated to read the synchronized system time.
And S101, issuing a reset instruction to a logic chip arranged in the server according to the system time and a preset first flashing period of the indicator lamp.
And determining that the server and the NTP server are synchronized according to the notice issued by the processor at the BMC. The BMC may calculate the time for issuing the reset instruction according to the system time and a preset first flashing period (for example, 4 seconds) of the indicator light, where the reset instruction is used to control the indicator light to start flashing again according to the first flashing period. The BMC may send the reset instruction to a Logic chip, where the Logic chip may be a CPLD (Complex Programmable Logic Device) or an FPGA (Field Programmable Gate Array), and the Logic chip may be used to manage the flashing of the indicator light, such as managing the enabling or disabling of the indicator light, the flashing period when enabled, and the like.
In order to reset the indicator light, a dedicated reset pin may be provided on the logic chip, or may be enabled and disabled once.
By means of the synchronized system time and the first flashing period, a plurality of resetting time points can be determined, the resetting time points are determined uniformly according to the synchronized system time, the set flashing periods are the same, and even if the starting time of the servers is different, the indicator lights after resetting can be enabled to flash synchronously. Therefore, after the servers switch the flashing periods of the indicating lamps due to abnormality, the staff can more quickly locate the abnormal servers, and the indicating lamps of the servers flash synchronously, so that the appearance of the machine room is not affected.
In addition, in order to avoid factors such as different distances between the logic chips in the servers and the indicator lights, after the servers are operated for a period of time, the indicator lights in the servers may have different flickering rhythms again, so that the periodic resetting can be performed according to the middle of the system, and the problem that the indicator lights have deviation again due to the aging of hardware when the indicator lights are operated for a long time is solved.
Optionally, the method further includes:
and S102, if the server is determined to be abnormal, flickering according to a preset second flickering cycle of the indicator lamp, and stopping sending a resetting instruction to the logic chip.
When the processor of the server finds the abnormality, an abnormality notification may be sent to the BMC, or the BMC may check the state of the server directly to confirm the abnormality.
After that, the BMC may issue a second flashing period to the logic chip according to a preset configuration, and since flashing synchronization between the plurality of servers is not required, it is not necessary to send a reset instruction to the logic chip.
Generally, the value of the second flashing period may be smaller than that of the first flashing period, that is, the flashing frequency is higher, so that the indicator light can be more easily recognized by the worker.
In a first possible implementation manner, in step S101, issuing a reset instruction to a logic chip arranged in a server according to the system time and a preset first flashing period of an indicator, where the method includes:
S101A, determining a plurality of reset time points according to the system time and the preset first flashing period of the indicator light.
And S101B, if the system time reaches the reset time point, issuing a reset instruction to a logic chip arranged in the server.
After acquiring the system time, the BMC may calculate more reset time points according to a first flashing period (for example, 4 seconds), where the reset time points are used to instruct the BMC to send a reset instruction to the logic chip. For example, it may be set that the reset is performed every 10 times of the first flash period for the first flash period, and then the reset period may be calculated, 4 × 10 ═ 40 seconds. Thereafter, a reset time point is determined according to the reset period, and the reset time point is recorded in a table form, as shown in table 1 below, starting from 0:00:00 seconds.
| 0:00:00 | 0:00:40 | 0:01:20 | 0:02:00 | 0:02:40 | 0:03:10 | …… | 23:59:20 |
TABLE 1
In the process that the BMC performs timing according to the system time, if the timing reaches the time recorded in the table, the BMC can issue a reset instruction to the logic chip to perform a reset on the flashing of the indicator light, so that the phenomenon that the distances from the logic chip to the indicator light in each server are different and the rhythm changes after long-time operation are avoided.
In a second possible implementation manner, in step S101, issuing a reset instruction to a logic chip set in the server according to the system time and a preset first flashing cycle of the indicator light, includes:
S101C, according to the system time and the preset first flashing period of the indicator light, determining the reset time point closest to the system time, and stopping the flashing of the indicator light.
And S101D, if the system time reaches the closest reset time point, issuing a reset instruction to a logic chip arranged in the server, and starting a timer.
And S101E, if the time of the timer reaches the preset time, issuing a reset instruction to a logic chip arranged in the server.
Wherein the preset time is an integral multiple of the first scintillation period.
After acquiring the system time, the BMC may calculate more reset time points according to a first flashing period (for example, 4 seconds), where the reset time points are time for instructing the BMC to send a reset instruction to the logic chip. For example, it may be set that the reset is performed every 10 times of the first flash period for the first flash period, and then the reset period may be calculated, 4 × 10 ═ 40 seconds. The BMC may determine the reset time point that is closest to the current system time based on the records of table 1 above.
For example, the synchronized system time obtained by the current BMC is 0:01:43, and it can be determined that the closest reset time point is 0:02: 00.
Thereafter, the BMC may issue a disable instruction to the logic chip to cause the indicator light to pause to indicate that the indicator light is in a synchronization process. When the BMC detects that the system time reaches the closest reset time point, the BMC issues a reset instruction, and starts a timer after the BMC issues the reset instruction at the time. According to the determined reset period, the timer starts timing, and when the preset time (set as the reset period in the embodiment) is reached, the BMC issues a reset instruction to the logic chip to enable the indicator lamp in the server to flash again based on the first flash period, so that the rhythm change caused by the fact that the distances from the logic chip to the indicator lamp in each server are different and the servers operate for a long time is avoided.
In a third possible implementation manner, in step S101, issuing a reset instruction to a logic chip disposed in a server according to the system time and a preset first flashing period of an indicator, includes:
S101F, according to the system time and the preset first flashing period of the indicator light, determining the reset time point closest to the system time, and stopping the flashing of the indicator light.
And S101G, if the system time reaches the nearest reset time point, issuing a reset instruction to a logic chip arranged in the server, and starting a counter.
The counter is used for recording the times of the indicator lamp flickering according to the first flickering cycle.
S101H, if the number of times of flashing recorded by the counter reaches the preset number of times, issuing a reset instruction to a logic chip arranged in the server.
After acquiring the system time, the BMC may calculate more reset time points according to a first flashing period (for example, 4 seconds), where the reset time points are time for instructing the BMC to send a reset instruction to the logic chip. For example, if the first flash period is set to be reset every 10 times, the reset period may be calculated, and 4 × 10 is 40 seconds. The BMC may determine the reset time point that is closest to the current system time based on the records of table 1 above.
For example, the synchronized system time obtained by the current BMC is 0:01:43, and it can be determined that the closest reset time point is 0:02: 00.
Thereafter, the BMC may issue a disable instruction to the logic chip to cause the indicator light to pause to indicate that the indicator light is in a synchronization process. When the BMC detects that the system time reaches the closest reset time point, the BMC issues a reset instruction, and starts a counter after the reset instruction is issued at the time. The BMC can also be provided with preset times of indicating lamp flashing, and when the flashing times recorded by the counter reach the preset times, the BMC sends a reset instruction to reset the indicating lamp once. Because the counter counts only when the flash is sent down once, compared with a timer, the counter needs to be in timing processing all the time, and more processing resources can be saved.
Correspondingly, the present application provides an indicator lamp synchronous flashing device, which is applied to a BMC in a server, as shown in fig. 2, and includes:
