[specific embodiment]
Refering to fig. 1 with Fig. 2, an embodiment of servo-system of the present invention, be electrically connected a power supply unit 100, the power supply supply
Device 100 is answered to generate a stand-by electric (standby power) and an electric power, and the servo-system includes multiple server lists
Member 2.
Each server unit 2 receives the stand-by electric and the electric power, and has a random start device (Random
Turn-on device) 1, and the random start device 1 includes a baseboard management controller (Baseboard Management
Controller) 11, one trigger signal generator 12 and a control chipset 13.
The baseboard management controller 11 be used in itself initialization loading procedure 111 start load booting data when, to rear
Hardware (such as control chipset 13) random triggering booting in advance is held, then proceedes to execute itself other initialization operation, it is random
Trigger specific implementation technology are as follows: the baseboard management controller 11 stores a predetermined time, and receives the stand-by electric to maintain to transport
Make, and continues via wherein two universal input output connecting pins (General Purpose Input/Ouput pin, GPIO
Pin one first logical signal and one second logical signal) are exported, first logical signal and second logical signal are settings
In one first level (such as logic 1) and one second level (such as logical zero) one of both.First logical signal is initially to be set in
First level, second logical signal are initially to be set in second level, when by a random time, the substrate management
Controller 11 sets first logical signal to second level, and when adding the predetermined time by the random time,
The baseboard management controller 11 sets second logical signal to first level.In detail, the baseboard management controller 11
Including one when the system initialization data needed for load booting initialization loading procedure (boot loader or uboot)
111, a random number generator 112, one for generating the random value that one is relevant to in-cycle work stores the buffer of the random value
113, one the first timer 114 and a basis of timing are carried out as the total amount for counting a random time according to the random value
The random time carries out the second timer 115 of timing, and first timing plus the predetermined time as the total amount counted
Device 114 and second timer 115 are to synchronize to countdown.
The trigger signal generator 12 be electrically connected the baseboard management controller 11 with receive first logical signal and this
Two logical signals, and generate the trigger signal that a pulse width is equal to the predetermined time.Specifically, the trigger signal generator
12 include one or 121, one first resistor 122 of door (OR gate) and a second resistance 123.It is somebody's turn to do or door 121 has a reception should
The first end of first logical signal, one receive second logical signal second end and one export the trigger signal output end.
The first resistor 122 has one to be electrically connected the power supply electricity of the first end and a reception of this or door 121 from the power supply unit 100
First logical signal is initially set in first level by the second end of power.The second resistance 123 has an electrical connection should
Or the second end of door 121 first end and a ground connection second end, it is second quasi- which is initially set in this
Position.
The control chipset 13 is electrically connected the trigger signal generator 12 or door 121 output end, and when the reception touching
When signalling, an in-cycle work is executed, in the present embodiment, which is with platform controller hub
(Platform Controller Hub, PCH) is implemented.
Cooperation is refering to Fig. 3, and the first above-mentioned level was logic 1, which is logical zero, at power-on time t=0 seconds
When, the first logical signal of the baseboard management controller 11 is initially set in logic 1, and the second logical signal is initially set in logic
0。
Then, the random value, such as 15 are randomly generated in the random number generator 112 of the baseboard management controller 11, and store up
The random value is deposited to the buffer, which sets the first timer 114 and open i.e. according to the random value
One random time of beginning timing, i.e., 15 seconds, and it is synchronous according to the stored predetermined time, it sets the second timer 115 and starts to count
When the random time add the predetermined time, such as 16 seconds (wherein the predetermined time be 1 second).
Then, at the end of 114 timing of the first timer random time (t=15 seconds), first logic can be triggered
Signal is converted into logical zero from logic 1；And the predetermined time (t is added when passing through 115 timing of the second timer random time
=16 seconds) at the end of, second logical signal can be triggered from logical zero and be converted into logic 1.At this point, this or door 121 are patrolled according to first
It collects the logic variation of signal and the second logical signal and generates a low logic pulse (low pulse) as the trigger signal to touch
Send out the control chipset 13.It supplements herein, although the present embodiment is that logical zero is by logic 1, the second level of the first level
Example explanation, but the two can also be implemented on the contrary, and generating the trigger signal is the high logical pulse positioned at logic 1, without with institute
The person of stating is limited.
Particularly, raw according to 11 random numbers of the baseboard management controller of the random start device 1 of each server unit 2
At all identical probability of the random value it is very low, that is to say, that each server unit 2 respectively according to the corresponding random value and
The all identical probability of the corresponding random time of timing is also very low respectively, therefore this case invention can reduce server unit 2 while hold
The probability of the row in-cycle work, thus reduce the chance for causing the power supply unit 100 to overload.
Further, since each server unit 2 is in the baseboard management controller 11 initialization, by the substrate pipe
Controller 11 is managed, and cooperates the trigger signal generator 12 to export trigger signal to start the control chipset 13, therefore this
Each server unit 2 of invention completes initialization (at least in the initialization loading procedure 111 of the baseboard management controller 11
45 seconds) before, in-cycle work can be executed, without etc. completion to be initiated, just for example through layout power-up sequence function,
It triggers next server unit 2 to be switched on, or penetrates the remotely controlled booting of remote connection function, therefore waiting can be saved just
The beginningization time；Moreover, each server unit 2 can at least be 1 second according to the random time, it also can be at 2 seconds, 3 seconds ... or more
Booting, that is, low logic pulse can be generated in various time points (1 second to any random time), execute in-cycle work.
Also, the initialization loading procedure 111 of the baseboard management controller 11 is only absorbed in load in initialization time and is opened
Machine data, such as the kernel (kernel) of (SuSE) Linux OS, and the in-cycle work be entirely by the first timer 114, this
The random value that two timers 115 are provided according to the random number generator 112, Lai Jinhang countdown, and the two waits until to count accordingly
When the time total amount one arrive, i.e., successively first logical signal that is exported of two universal input output connecting pins of triggering and this second
The automatic transition of logical signal, and cooperate should or door 121 reach the in-cycle work, so the first timer 114 and should at this time
The movement of second timer 115 is entirely that the hardware of the baseboard management controller 11 automatically controls, and unrelated initialization loads journey
The program of sequence 111 loads.
The available machine time of the server unit 2 of servo-system in conclusion the present invention is staggered, without causing power supply unit
100 overloads, and each server unit 2 can execute in-cycle work in random time, therefore the purpose of the present invention can be reached really.
Only as described above, only presently preferred embodiments of the present invention, when the model that cannot limit implementation of the invention with this
It encloses, i.e., all still belongs to according to simple equivalent changes and modifications made by claims of the present invention and patent specification content generally
In the range of the invention patent covers.
