Embodiment
Please refer to Fig. 1, Fig. 1 is the synoptic diagram that adopts an embodiment of the designed electronic system of the management method of startup of electronic installation of the present invention.Electronic system 100 includes (but being not limited to): a serial advanced technology attachment unit interface (Serial Advanced Technology Attachment, SATA) master controller 120 (being designated hereinafter simply as SATA master controller 120), a power supply assembly 130, one first hard disk collection 200, one second hard disk collection 300 and one the 3rd hard disk collection 400, wherein the first hard disk collection 200 includes hard disk 210 and hard disk 220; The second hard disk collection 300 includes hard disk 310 and hard disk 320; And the 3rd hard disk collection 400 include hard disk 410 and hard disk 420.It should be noted that the mentioned electronic system of present embodiment 100 does not limit its concrete enforcement aspect, that is electronic system 100 can be to be applied to the disk array that disk array or in the computer system is external in computer system.In addition, the sum of hard disk collection shown in Figure 1 and the quantity of the hard disk that comprised of each hard disk collection is only as the usefulness of example explanation, is not in order to as restriction of the present invention.
Different with existing disc array system is, the power supply assembly 130 of electronic system 100 of the present invention is through particular design, therefore when electronic system 100 starts, the first hard disk collection 200, the second hard disk collection 300 and the 3rd hard disk collection 400 are started immediately simultaneously, but wait 120 pairs of hard disks of SATA master controller to send an initialization control signal (out-of-band signal, the OOB signal) afterwards, those hard disks just can start, in this simultaneously, each hard disk just produces the electric current demand of several amperes.Therefore, the present invention sees through the time point dispersion of SATA master controller 120 with hard disk demand starting current, and a kind of implementation method wherein illustrates as follows.
At first, electronic system 100 starts, and SATA master controller 120 sends an OOB signal to hard disk in the first hard disk collection 200 210 and hard disk 220 earlier, hard disk 210 and hard disk 220 are after receiving this OOB signal, step motor (stepping motor) in hard disk 210 and the hard disk 220 just thereby start, this action need expend the main cause of higher electric current when also being hard disk startup.After hard disk 210 starts with hard disk 220, just can be respectively SATA master controller 120 be replied one and start and finish signal (for example the SATA standard is defined " FIS34 ").
After SATA master controller 120 receives the FIS34 signal, SATA master controller 120 sends the OOB signal to hard disk in the second hard disk collection 300 310 and hard disk 320 again, same as above, behind the FIS34 signal that hard disk in receiving the second hard disk collection 300 is replied, SATA master controller 120 just sends the OOB signal so that it is started to the hard disk in the 3rd hard disk collection 400 again.Should be noted that, spirit of the present invention is also paid no attention to the consistance that the concentrated hard disk startup of hard disk operates, and the notion that the dispersion that only need reach integral body starts gets final product, in other words, after SATA master controller 120 might not be waited until all concentrated hard disks passback FIS34 signals of a certain hard disk, the hard disk that another hard disk is concentrated sent the OOB signal again.For example, when SATA controller 120 after the second hard disk collection 300 is sent the OOB signal, as long as after by the time one in hard disk 310 and the hard disk 320 replied the FIS34 signal, can send the OOB signal to the hard disk that the 3rd hard disk is concentrated.Moreover, send on the order of OOB signal in the hard disk that 120 pairs of hard disks of SATA master controller are concentrated, under the situation of main spirit of the present invention, quite flexible variation also can be arranged.For example, SATA master controller 120 can be when sending the OOB signal for the first time, the OOB signal is sent to hard disk 210 in the first hard disk collection 200, second hard disk concentrates hard disk 310 in 300 and the hard disk 410 in the 3rd hard disk collection 400, when sending the OOB signal for the second time, the OOB signal is sent to other hard disk that does not start as yet again.
Comprehensive above-mentionedly learn that main spirit of the present invention is to disperse the time point of the startup of a plurality of electronic installations (as hard disk), to avoid causing power supply assembly that very big immediate current need be provided.Therefore, the emphasis that all non-the present invention of consistance of the action of the hard disk that hard disk startup sequencing of concentrating about hard disk and hard disk are concentrated are emphasized, as long as utilize in a plurality of electronic installations a part of electronic installation to reply after its startup finishes signal so meet the present invention, again other electronic installation that does not start is as yet transmitted the notion of initialization control signal, promptly belong to the category that the present invention is contained.
See also Fig. 2, Fig. 2 controls the process flow diagram of first embodiment of management method of the startup of a plurality of electronic installations for the present invention.If can obtain identical haply result, then the step of Fig. 2 and non-limiting will the execution in regular turn according to order shown in Figure 2.But the present invention controls the management method broad sense of the startup of a plurality of electronic installations and is summarized as follows:
Step 200: start electronic system.
Step 202: transmit an initialization control signal to the electronic installation that does not start as yet at least one electronic installation (for instance, an initialization control signal is sent to single electronic installation, is sent to a part of electronic installation that is arranged in identity set or is sent to the whole electronic installation that is arranged in identity set) to start this at least one electronic installation.
Step 204: whether detecting receives that the startup that this at least one electronic installation is replied finishes signal (for instance, detect receive the startup that single electronic installation is replied finish signal, receive be arranged in a plurality of startups that a part of electronic installation of identity set replied finish signal or receive be arranged in a plurality of startups that the whole electronic installation of identity set replys and finish signal)? if then execution in step 206; Otherwise, continue execution in step 204 and wait for that this electronic installation replys this startup and finish signal.
