Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, as will be appreciated by those of ordinary skill in the art, in the various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments may be mutually combined and referred to without contradiction.
A first embodiment of the present application relates to an out-of-band management switching device, with a specific structure shown in FIG. 2, including: a substrate controller 201, a first switch module 2021, and a second switch module 2022.
Specifically, the substrate controller 201 is connected to the first end of the first switch module 2021 through the NCSI interface, and the second end of the first switch module 2021 is connected to the first end of the second switch module 2022; the third end of the first switch module 2021, the second end of the second switch module 2022, and the third end of the second switch module 2022 are respectively connected to an out-of-band device 203; the first control terminal a of the substrate controller 201 is connected to the control terminal of the first switch module 2021, and the second control terminal b of the substrate controller 201 is connected to the control terminal of the second switch module 2022.
It should be noted that the out-of-band device 203 in fig. 2 is only for describing the connection relationship of the out-of-band management switching device, and is not one component of the out-of-band management switching device in this embodiment.
In this embodiment, the three out-of-band devices 203 have a priority ranking, where the out-of-band device 203 connected to the third terminal of the first switch module 2021 has the highest priority, and the substrate controller 201 may control the conducting directions of the first switch module 2021 and the second switch module 2022 according to the priority ranking. In practical applications, the substrate controller 201 selects one out-of-band device 203 with the highest priority to connect, that is, the first end of the first switch module 2021 is connected to the third end of the first switch module 2021, and when an abnormality occurs in the out-of-band device 203 connected to the third end of the first switch module 2021, the substrate controller 201 selects the out-of-band device 203 with the next priority to connect. In this embodiment, the priority of the out-of-band device 203 connected to the second end of the second switch module 2022 and the priority of the out-of-band device 203 connected to the third end of the second switch module 2022 may be the same or different, and the user may set the priorities according to actual needs, which is not specifically limited in this embodiment.
In the embodiment, the connection relation between the NCSI interface of the substrate controller and the out-of-band equipment is switched by arranging the first switch module and the second switch module, and at the moment, the server only needs to control the conduction path of the switch module through the control end, so that the operation pressure of the substrate controller is reduced compared with the case that the out-of-band equipment is selected for connection by using an arbitration mechanism in the related technology; meanwhile, in the method, when one out-of-band device needs to be replaced, only the switch module is controlled to be switched to the other out-of-band device for out-of-band management, so that the out-of-band device which needs to be replaced is isolated and then replaced, and abnormal out-of-band devices are replaced under the condition that the out-of-band management work process of the substrate controller is not affected.
It should be noted that, in this embodiment, through the above connection manner, a user may connect the out-of-band device with the highest priority to the third end of the first switch module according to actual needs, and only needs to control the first end of the first switch module to connect to the third end at this time, and the on state of the second switch module may be set arbitrarily; therefore, in the case of setting a plurality of switch modules, the embodiment can connect the out-of-band device with the highest priority only by controlling one switch module, thereby improving the efficiency of connecting the out-of-band device with the highest priority.
In one example, out-of-band device 203 may be an on-board network controller, an OCP network card, a network tag card. In this embodiment, the on-board network controller is the out-of-band device with the highest priority, so that the on-board network controller is connected to the third end of the first switch module, thereby improving the efficiency of connecting the on-board network controller with the highest priority.
Specifically, the OCP network card of the present embodiment is connected to the third end of the second switch module, and the network card is connected to the second end of the second switch module, where the priority of the OCP network card may be set to be greater than the priority of the network card. When the on-board network controller is abnormal, the substrate controller 201 controls the first end of the first switch module 2021 to be connected to the second end of the first switch module 2021, and the first end of the second switch module 2022 is connected to the third end of the second switch module 2022, so that the substrate controller 201 is connected to the OCP network card; when the OCP network card is abnormal, the substrate controller 201 controls the first end of the first switch module 2021 to be connected to the second end of the first switch module 2021, and the first end of the second switch module 2022 is connected to the second end of the second switch module 2022, so that the substrate controller 201 is connected to the network card.
In one example, the first and second switch modules 2021, 2022 may be switch-switching chips.
A second embodiment of the present application relates to an out-of-band management switching device. The second embodiment is substantially the same as the first embodiment, and in the second embodiment of the present application, the out-of-band management switching device further includes a third switch module. In order to avoid repetition, the same or corresponding parts of the present embodiment as those of the first embodiment are not described herein.
The specific structure of the out-of-band management switching device in this embodiment is shown in fig. 3, and includes: the substrate controller 301, the first switch module 3021, the second switch module 3022, and the third switch module 3023.
Specifically, the substrate controller 301 is connected to the first end of the first switch module 3021 through an NCSI interface; a second end of the first switch module 3021 is connected to a first end of the second switch module 3022, and a second end of the second switch module 3022 is connected to a first end of the third switch module 3023; the third end of the first switch module 3021, the third end of the second switch module 3022, the second end of the third switch module 3023, and the third end of the third switch module 3023 are respectively connected to one out-of-band device 303; the first control end a of the substrate controller 301 is connected to the control end of the first switch module 3021, the second control end b of the substrate controller 301 is connected to the control end of the second switch module 3022, and the third control end c of the substrate controller 401 is connected to the control end of the third switch module 3023.
In this embodiment, the four out-of-band devices 303 have a priority ranking, where the out-of-band device 303 connected to the third end of the first switch module 3021 has the highest priority, the out-of-band device 303 connected to the third end of the second switch module 3022 has the priority next to the out-of-band device 303 connected to the first switch module 3021, and the priorities of the out-of-band devices 303 connected to the second end and the third end of the third switch module 3023 may be the same or different, and the user may set the priority according to the actual needs. In practical applications, the substrate controller 301 may control the conducting directions of the first, second, and third switch modules 3021, 3022, and 3023 according to the priority order.
Specifically, the substrate controller 301 first selects one out-of-band device 303 with the highest priority to connect, that is, the first end of the first switch module 3021 is connected to the third end of the first switch module 3021; when an abnormality occurs in the out-of-band device 303 connected to the third terminal of the first switching module 3021, the substrate controller 301 switches connection to the out-of-band device 303 connected to the third terminal of the second switching module 3022; when an abnormality occurs in the out-of-band device 303 connected to the third terminal of the second switching module 3022, the substrate controller 301 switches the out-of-band device 303 connected to the second terminal or the third terminal of the third switching module 3023. It can be seen that, in this embodiment, the out-of-band devices 303 with different priorities may be connected to a designated location according to actual needs, and the different out-of-band devices 303 are switched and connected by the substrate controller 301 according to the priority sequence, that is, the substrate controller 301 sequentially switches and connects according to the priority sequence from high to low.
In one example, the third switch module 3023 is a switch switching chip.
It should be noted that, in this embodiment, through the above connection manner, a user may connect the out-of-band device with the highest priority to the third end of the first switch module according to the actual requirement, and connect the out-of-band device with the second priority to the third end of the second switch module, so as to ensure that when the device connected to the substrate controller is the out-of-band device with the highest priority, only the first switch module needs to be controlled, and when the device connected to the substrate controller is the out-of-band device with the second priority, only the first switch module and the second switch module need to be controlled, so that under the condition that a plurality of switch modules are provided, the number of actually controlled switch modules can be reduced, and the efficiency of connecting the substrate controller to the out-of-band device is improved.
A third embodiment of the present application relates to an out-of-band management switching device. The third embodiment is substantially the same as the first embodiment, and in the third embodiment of the present application, the out-of-band management switching device further includes a third switch module. In order to avoid repetition, the same or corresponding parts of the present embodiment as those of the first embodiment are not described herein.
The specific structure of the out-of-band management switching device of this embodiment is shown in fig. 4, and includes: a substrate controller 401, a first switching module 4021, a second switching module 4022, and a third switching module 4023.
Specifically, the substrate controller 401 is connected to a first end of the first switch module 4021 through an NCSI interface; the second end of the first switch module 4021 is connected to the first end of the second switch module 4022, and the third end of the first switch module 4021 is connected to the first end of the third switch module 4023; the second end of the second switch module 4022, the third end of the second switch module 4022, the second end of the third switch module 4023, and the third end of the third switch module 4023 are respectively connected to an out-of-band device 403; the first control end a of the substrate controller 401 is connected with the control end of the first switch module 4021, the second control end b of the substrate controller 401 is connected with the control end of the second switch module 4022, and the third control end c of the substrate controller 401 is connected with the control end of the third switch module 4023.
According to the embodiment, through the connection mode, a user can switch and connect different out-of-band devices according to actual demands, and compared with the method that an arbitration mechanism is used for selecting out-of-band devices for connection in the related technology, the operation pressure of a substrate controller is reduced; meanwhile, in the application, when one out-of-band device needs to be replaced, only the switch unit is required to be switched to the other out-of-band device, so that the out-of-band device can be replaced without affecting the out-of-band management work process of the substrate controller.
The above division of various components is for clarity of description, and it is within the scope of protection of the present patent that the above division of various components may be combined into one component or split into some components when implemented, as long as the same logical relationship is included.
The fourth embodiment of the present application relates to an out-of-band management switching method, which is used for a substrate controller of an out-of-band management switching device of the first embodiment, and it should be noted that the related technical details mentioned in the first embodiment are still valid in the present embodiment, and in order to reduce repetition, a detailed description is omitted here.
The specific flow of the out-of-band management switching method in this embodiment is shown in fig. 5, and includes the following steps:
in step 501, a first terminal of a first switch module is controlled to be connected to a third terminal of the first switch module.
Specifically, the execution body of the embodiment is a substrate controller of the out-of-band management switching device, and the substrate controller first selects out-of-band device connection connected to the third terminal of the first switch module.
It should be noted that, there is a priority order between the out-of-band devices, where the out-of-band device connected to the third end of the first switch module has the highest priority, and under the condition that the out-of-band device with the highest priority can work normally, the out-of-band device with the highest priority is selected as the out-of-band device to be connected for connection, and only when the out-of-band device with the first priority is abnormal, the out-of-band device with the second priority is selected for connection, and so on.
Step 502, determining whether the out-of-band device connected to the third terminal of the first switch module is normal. Returning to step 501 when the out-of-band device is normal; when the out-of-band device is abnormal, step 503 is entered.
Specifically, after controlling the first end of the first switch module to be connected to the third end of the first switch module, that is, after the substrate controller is connected to the out-of-band device connected to the third end of the first switch module, it is determined whether the out-of-band device is normal. Returning to step 501 when the out-of-band device is normal; when the out-of-band device is abnormal, step 503 is entered.
In practical application, when one out-of-band device such as the first out-of-band device fails and needs to be replaced, the substrate controller can be connected to other out-of-band devices such as the second out-of-band device through the control switch module, so that the first out-of-band device is isolated from the substrate controller, and at the moment, the replacement of the first out-of-band device can be completed without stopping the work between the substrate controller and the second out-of-band device, and the out-of-band management work efficiency of the substrate controller is improved.
In one example, determining whether the out-of-band device connected to the third terminal of the first switch module is normal includes: acquiring an interaction signal for communication with out-of-band equipment connected with a third end of the first switch module; judging whether the interaction signal meets a preset condition or not; if yes, judging that the out-of-band equipment connected with the third end of the first switch module is normal; if not, the out-of-band equipment connected with the third end of the first switch module is judged to be abnormal. A method for specifically judging whether a substrate control connected out-of-band device is normal or not is provided.
Step 503 controls the first end of the first switch module to be connected to the second end of the first switch module, and controls the first end of the second switch module to be connected to the second end or the third end of the second switch module.
Specifically, when the out-of-band device connected to the third end of the first switch module is abnormal, the substrate controller needs to switch connection to another out-of-band device, and thus, the substrate controller controls the first end of the first switch module to be connected to the second end of the first switch module and controls the first end of the second switch module to be connected to the second end or the third end of the second switch module.
It should be noted that, the priorities between the two out-of-band devices connected to the second end and the third end of the second switch module may be the same or different, and the user may set the priority between the two out-of-band devices according to the actual needs, and when the out-of-band device connected to the third end of the first switch module is abnormal, the substrate controller connects one out-of-band device with higher priority among the two out-of-band devices.
A fifth embodiment of the present application relates to an out-of-band management switching method, which is used for the substrate controller of the out-of-band management switching device of the second embodiment. It should be noted that the related technical details mentioned in the second embodiment are still valid in this embodiment, and are not repeated here for reducing repetition.
The specific flow of the out-of-band management switching method in this embodiment is shown in fig. 6, and includes the following steps:
in step 601, a first terminal of the first switch module is controlled to be connected to a third terminal of the first switch module.
Step 602, determining whether the out-of-band device connected to the third terminal of the first switch module is normal. If so, returning to the step 602; if so, the process proceeds to step 603.
Steps 601 to 602 and steps 501 to 502 in the fourth embodiment are not repeated here.
Step 603, controlling the first end of the first switch module to be connected to the second end of the first switch module, and controlling the first end of the second switch module to be connected to the third end of the second switch module.
In this embodiment, the priority of the out-of-band device connected to the third terminal of the first switch module is highest, and the priority of the out-of-band device connected to the third terminal of the second switch module is second. When the out-of-band equipment with the highest priority operates normally, namely the out-of-band equipment connected with the third end of the first switch module is normal, the substrate controller maintains an original control mode; when the out-of-band device with the highest priority is abnormal, namely the out-of-band device connected with the third end of the first switch module is abnormal, the substrate controller switches and connects to the out-of-band device with the second priority, namely the first end of the first switch module is connected to the second end of the first switch module, and controls the first end of the second switch module to be connected to the third end of the second switch module.
Step 604, determining whether the out-of-band device connected to the third terminal of the second switch module is normal. If so, returning to step 603; if so, the routine proceeds to step 605.
In one example, determining whether the out-of-band device connected to the third terminal of the second switch module is normal includes: acquiring an interaction signal for communication with out-of-band equipment connected with a third end of the second switch module; judging whether the interaction signal meets a preset condition or not; if yes, judging that the out-of-band equipment connected with the third end of the second switch module is normal; if the first terminal is not met, the out-of-band equipment connected with the third terminal of the second switch module is judged to be abnormal.
Step 605 controls the first end of the first switch module to be connected to the second end of the first switch module, controls the first end of the second switch module to be connected to the second end of the second switch module, and controls the first end of the third switch module to be connected to the second end or the third end of the third switch module.
Specifically, when the out-of-band device of the second priority operates normally, that is, when the out-of-band device connected to the third end of the second switch module is normal, the substrate controller maintains the original control mode; when the out-of-band equipment of the second priority is abnormal, namely the out-of-band equipment connected with the third end of the second switch module is abnormal, the substrate controller is switched and connected to the out-of-band equipment of the next priority, namely the first end of the first switch module is connected to the second end of the first switch module, the first end of the second switch module is connected to the second end of the second switch module, and the first end of the third switch module is connected to the second end or the third end of the third switch module.
It should be noted that, the priorities of the out-of-band devices connected to the second end and the third end of the third switch module may be the same or different, and the user may set the priority between the two out-of-band devices according to the actual needs, and when the out-of-band device with the second priority is abnormal, the substrate controller connects the out-of-band device with the higher priority of the two out-of-band devices.
A sixth embodiment of the present invention relates to an out-of-band management switching method, which is applied to the substrate controller of the out-of-band management switching device of the third embodiment. It should be noted that the related technical details mentioned in the third embodiment are still valid in this embodiment, and are not repeated here for reducing repetition.

and 701, selecting a target out-of-band device from a plurality of out-of-band devices according to a preset rule.
Specifically, the substrate controller selects a target out-of-band device for connection according to a preset rule. In one example, the substrate controller stores a prioritization of a plurality of out-of-band devices, the preset rule being: selecting the out-of-band device with the highest priority as a target out-of-band device; when the out-of-band device with the highest priority is abnormal, selecting the out-of-band device with the second priority as a target out-of-band device; when the out-of-band device of the second priority is abnormal, selecting out-of-band device of the third priority as the target out-of-band device; and when the out-of-band device with the third priority is abnormal, selecting the out-of-band device with the fourth priority as the target out-of-band device. Specifically, the substrate controller may preferentially select the out-of-band device with the highest priority as the target out-of-band device for connection, when the out-of-band device with the highest priority is abnormal, the substrate controller selects the out-of-band device with the second priority as the target out-of-band device for connection, when the out-of-band device with the second priority is abnormal, the substrate controller selects the out-of-band device with the third priority as the target out-of-band device for connection, and so on.
Step 702, controlling the conducting directions of the first switch module, the second switch module and the third switch module to connect the substrate controller with the target out-of-band device.
In this embodiment, the target out-of-band device is selected from the plurality of out-of-band devices through the preset rule, so that the process of switching the connection of the out-of-band devices by the substrate controller can be sequentially performed, and the switching efficiency is improved.
