In certain embodiments, equipment cabinet management controller 100 can not also have segmentation module 152, but it is outside be plural usability of program fragments by the cutting of tough body renewal program in advance, that is, equipment cabinet management controller 100 directly obtains plural usability of program fragments to more new procedures source 800, this a little usability of program fragments sequentially with a numbering, may know that the order of this little usability of program fragments with sharp equipment cabinet management controller 100 and rack backboard 200.
The 5th figure is refer to, here updates two rack backboards 200 simultaneously with equipment cabinet management controller 100（That is the first rack backboard and the second rack backboard）Firmware as a example by explanation.Step S802：The broadcast module 151 of equipment cabinet management controller 100 broadcasts the second communication interface 210 of a update notification to all rack backboards 200 via the first communication interface 110, and update notification can include the archives size of tough body renewal program and the data length of the usability of program fragments of each transmission；Or the quantity of usability of program fragments can be included.Thereby, the second processing device 220 of rack backboard 200 can record the archives size or total how many usability of program fragments of tough body renewal program, and can know whether to have received whole tough body renewal programs（I.e. all of usability of program fragments）.In this, the second processing device 220 for receiving the rack backboard 200 of update notification can return a preparation message to equipment cabinet management controller 100 via the second communication interface 210, and expression has been received by update notification, and is ready for updating.
Step S803：The second processing device 220 of each rack backboard 200 is received after update notification via the second communication interface 210, gradually sends the request message of each usability of program fragments of correspondence to equipment cabinet management controller 100 via the second communication interface 210.Then, in step S804, the program update module 153 of equipment cabinet management controller 100 gradually respond request message and transmit the usability of program fragments of correspondence to sending the rack backboard 200 of asking message via the first communication interface 110.Here, as rack backboard 200 can learn the usability of program fragments sum of tough body renewal program institute cutting via the data length of the tough body renewal procedural file size described in update notification and each usability of program fragments or according to the quantity of usability of program fragments.Therefore, the second processing device 220 of rack backboard 200 can ask the usability of program fragments of the specific numbers within the scope of the sum of usability of program fragments to equipment cabinet management controller 100（For example, if sum is 500, serial number 1 ~ 500）.Specific practice is the sequence number for asking message include the usability of program fragments of request transmission, therefore equipment cabinet management controller 100 is after request message is received, and the usability of program fragments of reference numeral can be found out according to this sequence number, and will correspondence sequence number（I.e. sequence number is identical with numbering）Usability of program fragments be sent to send request message rack backboard 200.For example：If 200 first program fragment to be asked of rack backboard, request message includes the first sequence number（Serial number 1）, then equipment cabinet management controller 100 transmission numbering be similarly 1 usability of program fragments（That is first program fragment）；If rack backboard 200 is intended to ask second usability of program fragments, request message to include the second sequence number（Serial number 2）, then equipment cabinet management controller 100 transmission numbering be similarly 1 usability of program fragments（That is first program fragment）.
In another embodiment, the quantity of aforementioned usability of program fragments and the data length of usability of program fragments can not included in the update notification of 100 broadcast of equipment cabinet management controller, and the only archives size comprising tough body renewal program.Rack backboard 200 learns after the archives size of tough body renewal program that via update notification the data length and usability of program fragments that can decide the usability of program fragments of each request in its sole discretion needs the number of times for transmitting altogether.Therefore, ask message not include the sequence number of usability of program fragments, but be loaded with the original position and data length of the usability of program fragments to be obtained.In step S804, the usability of program fragments of corresponding original position and data length in tough body renewal program is sent to the rack backboard 200 for sending this request message for contained original position and data length in 100 respond request message of equipment cabinet management controller.Then, tough body renewal program can cutting be separately also independent plural usability of program fragments；Or more new procedures source 800 needs not be provided the plural usability of program fragments of cutting, it is only necessary to provide tough body renewal program.In certain embodiments, the size of data of the usability of program fragments of each request of rack backboard 200 transmission also can be identical.
In certain embodiments, the data length of the usability of program fragments of transmission every time can be specified by equipment cabinet management controller 100, and data length is recorded in update notification.Rack backboard 200 just can gradually ask the usability of program fragments of correspondence original position according to the data length specified in update notification.Here, request message can include the original position of the usability of program fragments of request, and data length is not included.
As shown in Figure 5, the first rack backboard first sends the first request message, and asks the first usability of program fragments to equipment cabinet management controller 100.After equipment cabinet management controller receives the first request message that the first rack backboard sends, the first usability of program fragments that the first rack backboard correspondence first asks message is replied.Then, the first rack backboard continues to send the second request message, to ask the second usability of program fragments to equipment cabinet management controller 100.After equipment cabinet management controller 100 receives the second request message that the first rack backboard sends, the second usability of program fragments that the first rack backboard correspondence second asks message is replied.On the other hand, the second rack backboard equally sends the first request message at the beginning, to ask the first usability of program fragments to equipment cabinet management controller 100.After equipment cabinet management controller 100 receives the first request message that the second rack backboard sends, the first usability of program fragments that the second rack backboard correspondence first asks message is replied.In order to allow each rack backboard 200 simultaneously to 100 requestor fragment of equipment cabinet management controller, and can receive whole usability of program fragments without waiting for single rack backboard 200 in same period, equipment cabinet management controller 100 is with first in first out（FIFO, First In First Out）Queue（Queue）, and request message responder fragment that can preferentially for first receiving.Here, aforementioned first usability of program fragments means the usability of program fragments of first request；Aforementioned second usability of program fragments means the usability of program fragments of second request, and not necessarily is first, second usability of program fragments after tough body renewal program cutting.Rack backboard 200 is gradually to send request message according to the order of this little usability of program fragments.For example, the first program fragment that rack backboard 200 can be in order from after cutting starts to 100 requestor fragment of equipment cabinet management controller, it is also possible to start request from other usability of program fragments in order.But embodiments of the present invention are not limited to this, also can not ask in order, and request message is sent with random number order gradually.
With reference to the 6th figure, it is the signal transmission schematic diagram of another embodiment of the present invention.Make a mistake when the rack backboard 200 for sending request message receives usability of program fragments（As shown in fork is made in figure）, then the request message comprising identical sequence number is sent again to equipment cabinet management controller 100.For example, after the first rack backboard sends the first request message at the beginning, equipment cabinet management controller 100 fails to be properly received the first request message, then make a mistake.First rack backboard can send second first request message again because failing to receive the response of equipment cabinet management controller 100 in a response time, then.That is, after rack backboard 200 sends request message（I.e. after step S803）, rack backboard 200 may wait for a response time, if failing the usability of program fragments of 100 response of equipment cabinet management controller is received in response time, can send request message again.
If the first request message that the first rack backboard sends for second is properly received by equipment cabinet management controller 100, equipment cabinet management controller 100 can return correspondence first and ask the first usability of program fragments of message to the first rack backboard.Now, it is assumed that the first rack backboard makes a mistake when receiving the first usability of program fragments（As shown in fork is made in figure）, such as the first rack backboard still wait in another response time less than equipment cabinet management controller 100 reply the first usability of program fragments；Or receive mistake（The first usability of program fragments as only received part, but fail complete reception, or the data for receiving are wrong）, then the first rack backboard can send the first request message again to equipment cabinet management controller 100, equipment cabinet management controller 100 need not be returned and made a mistake, and message degree of transitivity can be reduced.
Then, according to above-mentioned mode, until rack backboard 200 receives all of usability of program fragments from equipment cabinet management controller 100, just can be updated.It is multiple that with reference to the 4th figure, in step S805, this little usability of program fragments can be reduced to tough body renewal program by the rack backboard 200 for having received all usability of program fragments, and with this former firmware program of tough body renewal program renewal.In detail, when the usability of program fragments stored by the second processing device of rack backboard 200 checks the second bin 230 is complete, then this little usability of program fragments sequentially can be combined and be reduced to tough body renewal program, and then the former firmware program run by script is updated with this tough body renewal program.
Before being updated, rack backboard 200 can transmit and terminate message to equipment cabinet management controller 100, to notify that equipment cabinet management controller 100 has completed the transmission of all usability of program fragments.As shown in Figure 6, the second rack backboard is receiving last usability of program fragments（It is n-th in this, N is natural number）Afterwards, send and terminate message to equipment cabinet management controller 100.In this, if equipment cabinet management controller 100 does not slowly receive the request message of a certain rack backboard 200, also do not received its transmission terminates message, just can determine that 200 possible breakdown of rack backboard and needs artificial intervention to exclude.
In sum, the firmware updating method of the server cabinet of embodiment of the present invention proposition, the change past first transmits usability of program fragments to rack backboard 200 by equipment cabinet management controller 100, replied by rack backboard 200 again and whether be properly received, if, equipment cabinet management controller 100 just transmits the practice of next usability of program fragments again, omits and replys the message transmission whether being properly received.Meanwhile, it is capable of achieving all rack backboards 200 and updates together and more time-consuming, the time more than half can be saved compared to the past practice.In addition, can also reduce updating the risk that mistake causes renewal interruption.
