The control circuit reads current setting data corresponding to the server from the cloud server in a power-on self-detection stage of the server, compares the actual setting data with the current setting data, and when the actual setting data is inconsistent with the corresponding current setting data, sends the actual setting data to the cloud server so that the actual setting data covers the current setting data.
Description
Technical Field
The present invention relates to a server, and more particularly to a server for setting data of BIOS setting options.
Background
With the progress of technology, the information amount required to be stored by people is greatly expanded, and the cloud storage or cloud backup data center is widely used, namely, a third party provides and hosts a plurality of cloud servers, and a user stores data in the large data center operated by the third party in an online storage mode so as to meet the requirement of data storage, and the user does not need to install a physical storage device in an office, so that the equipment and management cost is greatly reduced.
When an enterprise or a person manages the server of the workstation, the actual system setting of the workstation server can be stored by the cloud server, so that a manager can quickly refer to the current system setting recorded in the cloud server, the manager can log in the cloud server through a network to refer to the current system setting corresponding to the workstation server, and modify the current system setting stored in the cloud server through the network, so that in the restarting process of the workstation server, the workstation server loads the modification of the current system setting by the manager through the cloud server from the cloud server, and the actual system setting of the workstation server is indirectly modified. However, the manager may modify the actual system setting of the workstation server in another manner, that is, the manager may directly modify the actual system setting of the workstation server on-line (off-line) by directly using an input device or a computer linked to the workstation server, but support both modification manners (direct/indirect) to easily cause a problem that the actual system setting is inconsistent with the current system setting, and if the manager considers the current system setting stored in the cloud server and inconsistent with the actual system setting of the workstation server as the actual system setting of the workstation server in a situation that the actual system setting is inconsistent with the current system setting, the manager may indirectly perform an erroneous setting on the workstation server by referring to the current system setting inconsistent with the actual system setting of the workstation server, which may cause a problem that the workstation server cannot operate normally after restarting.

[ Detailed description ] of the invention
Fig. 1 is a schematic diagram of a first embodiment of a server according to the present disclosure, referring to fig. 1, a server 1 (hereinafter referred to as a proximal server 1) may be connected to a cloud server 2 via a network 3, the cloud server 2 may be a remote server linked to a plurality of proximal servers 1 via the network 3, the cloud server 2 stores a current setting data, wherein the current setting data includes a first current setting corresponding to a Basic Input Output System (BIOS) setting option, and a user may operate the cloud server 2 via the network 3 or directly via an input device or a computer directly linked to the cloud server 2 to read the current setting data and learn what actual setting data corresponds to the corresponding proximal server 1 by using the current setting data. Therefore, in order to make the actual setting data of the near-end server 1 consistent with the current setting data, the near-end server 1 can compare the actual setting data with the corresponding current setting data and judge whether the two data are consistent so as to determine whether to update the current setting data, so that the current setting data stored in the cloud server 2 is consistent with the actual setting data stored in the near-end server 1.
In detail, as shown in fig. 1, the near-end server 1 includes a BIOS memory 11 and a control circuit 12 coupled to the BIOS memory 11. The BIOS memory 11 stores BIOS program codes, and the BIOS memory 11 stores actual setting data corresponding to a plurality of settable BIOS setting options corresponding to the BIOS program codes. As described above, in order to ensure that the current setting data stored in the cloud server 2 is consistent with the actual setting data of the near-end server 1, in each boot self-test phase of the near-end server 1, that is, the period of time before the boot self-test phase is to be completed and the operating system is to be loaded, if the user is to directly connect the near-end server 1 to modify the actual setting data, since the boot program is not allowed to be interrupted randomly, the action of directly modifying the actual setting data must be performed before the boot self-test (POST) procedure is completed until the operating system is loaded, that is, after the necessary hardware and system settings are checked to be completed, the system allows the user to modify the actual setting data by switching into a BIOS boot menu (BIOS setup menu) for the user to be in the BIOS boot menu, the control circuit 12 reads the current setting data from the cloud server 2 by executing the BIOS program code (step S01), and the control circuit 12 executes the BIOS program code to obtain the actual setting data corresponding to the current setting data, if the control circuit 12 is not consistent with the actual setting data corresponding to the actual setting data (step S02) of the current setting data is compared with the actual setting data (if the current setting data is not consistent with the actual setting data in the current setting data 1) of the current setting data (step 1) and the actual setting data is not being stored in the actual setting data 1, and the modified actual setting data is not stored in the cloud server 2, so that the first current setting is inconsistent with the corresponding actual setting), the control circuit 12 may send the actual setting data including all the actual settings to the cloud server 2 via the network 3 (step S03) to update the current setting data (hereinafter, the current setting data before update and the current setting data after update are referred to as the first current setting data and the second current setting data, respectively).
Thus, the first current setting data in the cloud server 2 is covered by the actual setting data from the near-end server 1, the cloud server 2 stores a second current setting datagram of the near-end server 1 corresponding to a plurality of BIOS setting options, and the second current setting datagram is an actual setting of a plurality of BIOS setting options of the near-end server 1, that is, the second current setting is consistent with an actual setting stored in the BIOS memory 11 and corresponding to one of the BIOS setting options, and when the manager of the near-end server 1 views the BIOS setting options of the near-end server 1 through the cloud server 2, the manager does not refer to the first current setting of the first current setting data, that is, the manager can further perform setting modification on the near-end server 1 according to the second current setting of the second current setting data which actually and respectively and correctly corresponds to the current setting.
In one embodiment, in step S01, the control circuit 12 may download the current setting data of the corresponding near-end server 1, such as the first current setting data before updating or the second current setting data after updating, from the cloud server 2, and store the current setting data in a buffer (buffer). The control circuit 12 may store the actual setting data obtained from the BIOS memory 11 in a buffer to perform the comparison operation of step S02 by the data stored in the buffer. The control circuit 12 may store the current setting data and the actual setting data in different buffers.
In an embodiment, the manager may store the update setting data corresponding to the actual setting data of the near-end server 1 in the cloud server 2, the near-end server 1 may connect to the cloud server 2 through the network 3, and check whether the cloud server 2 includes the update setting data corresponding to the near-end server 1, when the manager stores the update setting data in the cloud server 2, the near-end server 1 may update the actual setting in the corresponding actual setting data according to the plurality of update settings included in the update setting data, so as to complete the update of the actual setting data of the near-end server 1 in a remote indirect manner.
Therefore, in each power-on self-detection stage of the near-end server 1, the control circuit 12 is connected to the cloud server 2 through the network 3 before executing step S01, the control circuit 12 determines whether the cloud server 2 includes updated setting data corresponding to the actual setting data (step S04), and when the cloud server 2 does not include updated setting data (no in the determination result), the control circuit 12 executes step S01 to read the current setting data stored in the cloud server 2 (for example, to read the first current setting and the second current setting included in the current setting data stored in the cloud server 2 in advance), and then executes step S02. On the other hand, in step S04, when the cloud server 2 already includes the update setting data corresponding to the near-end server 1 (yes in the determination result), the control circuit 12 updates the corresponding actual setting data according to the update setting data (step S05), so that each update setting of the update setting data in the cloud server 2 matches with the corresponding actual setting in the corresponding near-end server 1.
After the update step is completed, the near-end server 1 is reset (step S06), and the control circuit 12 again executes step S04 in the power-on self-test procedure after the reset of the near-end server 1 to determine whether the cloud server 2 includes the update setting data. At this time, since the control circuit 12 has updated its actual setting data according to the updated setting data in the power-on self test procedure before the reset, in the power-on self test procedure after the reset, the control circuit 12 determines that the cloud server 2 does not include the updated setting data corresponding to the actual setting data (no in the determination result), the control circuit 12 skips the updating step S05 of the BIOS setting option, and the control circuit 12 executes steps S01 and S02.
In step S02, since the control circuit 12 has updated the actual settings of the actual setting data, the control circuit 12 determines in step S02 that at least one of the actual settings of the actual setting data does not coincide with the corresponding first current setting (no determination result). For example, taking the first current setting as an example, if the control circuit 12 updates the actual setting of one corresponding actual setting data with one of the updated settings in the updated setting data, for example, the control circuit 12 updates the fourth actual setting in the actual setting data, the control circuit 12 determines that the updated fourth actual setting is not the same as the corresponding first current setting. Next, the control circuit 12 sends the actual setting data to the cloud server 2 (step S03), so that the actual setting data stored in the BIOS memory 11 is consistent with the current setting data stored in the cloud server 2.
In one embodiment, in step S02, when the control circuit 12 determines that the actual setting data of the near-end server 1 is consistent with the corresponding current setting data (yes in the determination result), for example, after the current setting data is updated to the second current setting data, the control circuit 12 determines that the actual setting data is consistent with the second current setting data, and the control circuit 12 continues to execute the BIOS program code to continue to execute the power-on process of the near-end server 1 (step S07). When the control circuit 12 determines that the actual setting data of the near-end server 1 does not match the corresponding current setting data (no result), for example, the actual setting data does not match the first current setting data, the control circuit 12 continues to perform the power-on process of the near-end server 1 after executing step S03 (step S07).
In one embodiment, the cloud server 2 can detect whether the cloud server itself includes an update file for storing update setting data corresponding to actual setting data of the near-end server 1 at the time of startup, and if the update file does not exist, the cloud server 2 establishes the update file according to a preset file name corresponding to an identifier of the near-end server 1. The manager of the near-end server 1 can find the update file according to the default file name through the interface of the web page (web page), and establish or modify the first current setting corresponding to at least one BIOS setting option of the near-end server 1 to be updated in the update file as at least one update setting of the update setting data. Furthermore, the update file may include only a portion of the BIOS setting options, for example, the near-end server 1 includes 50 BIOS setting options, and the update setting data may only correspond to the actual setting data of three of the BIOS setting options, that is, when the near-end server 1 updates its own actual setting data with the update setting data, the near-end server 1 may only update the corresponding three actual setting data in its own actual setting data with the update setting data, or the actual setting data corresponding to the other portion of the BIOS setting options.
In one embodiment, the near-end server 1 communicates with the cloud server 2 through an Application Programming Interface (API) using Representational state transfer (REST) protocol technology, so as to read current setting data from the cloud server 2 in step S01 and send the corresponding actual setting data of the near-end server 1 to the cloud server 2 in step S03. The cloud server 2 may also display the first current setting and the second current setting through a web application programming interface, so that the manager may refer to the current setting data of the corresponding near-end server 1 to obtain the history of the modified actual setting data of the corresponding near-end server 1 and the current latest state.
Referring to fig. 3, fig. 3 is a schematic diagram of a second embodiment of a server according to the present disclosure. Fig. 3 illustrates a server 4, wherein the server 4 includes a baseboard management controller 41, a control circuit 42, a first nonvolatile memory 43, and a second nonvolatile memory 44. The first nonvolatile memory 43 is coupled to the control circuit 42, the control circuit 42 is coupled to the baseboard management controller 41, the baseboard management controller 41 is coupled to the second nonvolatile memory 44, and the baseboard management controller 41 has a network connection function connected to the remote device 5.
The first non-volatile memory 43 is the aforementioned BIOS memory 11, and the first non-volatile memory 43 stores the aforementioned BIOS program code and the actual setting data corresponding to the plurality of BIOS setting options, which are not described herein. The second non-volatile memory 44 is used for storing current setting data corresponding to the actual setting data stored in the first non-volatile memory 43 and corresponding update files. In other words, the difference between the second embodiment and the first embodiment is that the current setting data and the updated setting data corresponding to the actual setting data of the BIOS setting option executed by the BIOS program code in the first nonvolatile memory 43 are stored in the second nonvolatile memory 44 coupled to the baseboard management controller 41 inside the server 4 instead of other servers. Furthermore, in the second embodiment, the manager of the server 4 can operate a remote device 5 connected to the baseboard management controller 41 of the server 4 through the network 3, and the manager can store the update setting data in the second non-volatile memory 44 through the network interface of the baseboard management controller 41, that is, the baseboard management controller 41 can receive the update setting data from the remote device 5 and store the update setting data in the second non-volatile memory 44.
Accordingly, referring to fig. 2 and 3, in the power-on self-test phase of the server 4, that is, in the initial power-on self-test phase or immediately before the power-on self-test phase, since the server 4 generally after the initialization of the control circuit 42 including its own main components (e.g., the initialization of the main components related to executing the BIOS program code such as the central processing unit (Central Processing Unit; CPU), the platform path controller (Platform Controller Hub; PCH), etc.), the control circuit 42 loads the BIOS program code and the corresponding actual setting data thereof to perform the power-on self-test, the control circuit 42 uses the updated setting data to update the actual setting data, whether the updated setting data of the BIOS setting option is included in the second non-volatile memory 44 is confirmed by the baseboard management controller 41 (step S04), the control circuit 42 may send a signal to the baseboard management controller 41 to report whether the updated setting data is included in the second non-volatile memory 44 of the baseboard management controller 41. When the second non-volatile memory 44 contains the update setting data (yes), for example, the manager has stored the update setting data in the second non-volatile memory 44 through the remote device 5, and the control circuit 42 obtains the update setting data through the baseboard management controller 41. The control circuit 42 sends a control signal to the baseboard management controller 41 to enable the baseboard management controller 41 to return updated setting data stored in the second non-volatile memory 44, and the control circuit 42 then updates the BIOS setting options according to the updated setting data (step S05).
After the update of the setting data of the BIOS setting option is completed, the server 4 resets (step S06), in the period of time before the reset power-on self-test stage is completed, i.e., the period of time before the power-on self-test stage is completed and the loading of the operating system is about to be completed, the control circuit 42 again executes step S04 to determine whether the update setting data exists, at this time, since the control circuit 42 has updated the actual setting data corresponding to a part of the BIOS setting options according to the update setting data before the server 4 resets, and the update setting data which has been used for updating the actual setting data is removed from the second non-volatile memory 44 by the baseboard management controller 41, that is, after the baseboard management controller 41 transmits the update setting data to the control circuit 42 to update the actual setting data, the update setting data in the baseboard management controller 41 is regarded as the update setting data which has been used for updating the actual setting data, in the self-test stage after the reset self-test stage, the baseboard management controller 41 reports that the update setting data in the second non-volatile memory 44 does not include the update setting data, so that the control circuit 42 determines that the second non-volatile memory 44 has not included the update setting data and the update data is included in the update file, and the update data is indicated by the update data which has been used for setting data in the update file is made immediately after the update of the setting data is detected by the update data of the update data which has been carried out by the baseboard management controller 41, the baseboard management controller 41 reports that the second non-volatile memory 44 does not include the unused updated setting data, so that the control circuit 42 determines that the second non-volatile memory 44 does not include the unused updated setting data (no in the determination result), and the control circuit 42 reads the current setting data stored in the second non-volatile memory 44 (step S01). The control circuit 42 can send a control signal to the baseboard management controller 41 again, so that the baseboard management controller 41 returns the current setting data stored in the second non-volatile memory 44.
The control circuit 42 then determines whether the actual setting data stored in the first nonvolatile memory 43 matches the corresponding current setting data stored in the second nonvolatile memory 44 (step S02), and since the control circuit 42 has updated the actual setting data with the updated setting data, the control circuit 42 generates a determination result of inconsistency (no in the determination result), and the control circuit 42 then transmits the updated actual setting data to the baseboard management controller 41 (step S03), so that the baseboard management controller 41 stores the updated actual setting data in the second nonvolatile memory 44 to overwrite the current setting data originally stored in the second nonvolatile memory 44 as the latest current setting data (hereinafter referred to as current setting data including the second current setting). Thereafter, if the manager does not store the updated setting data in the second non-volatile memory 44 by the baseboard management controller 41 and the manager does not directly modify the setting data of the BIOS setting option by the boot menu (boot menu) or directly modify the actual setting data by the tool connecting to the server 4 when the control circuit 42 executes the BIOS program code, in each boot self-checking stage, the control circuit 42 will generate a determination result (no) that the updated setting data does not exist when executing step S04, and accordingly execute steps S01 and S02, and the control circuit 42 will generate a determination result (yes) that the actual setting data of the BIOS setting option corresponding to the BIOS program code matches the current setting data including the second current setting when executing step S02, the manager of the near-end server 1 checks the BIOS setting option of the server 4 by the remote device 5, and does not perform correct maintenance on the current setting or correct maintenance on the near-end server 1 before each of the actual setting data of the near-end server 1 has been updated to correspond to each second current setting and is also referred to the first current setting when executing step S02.
In the second embodiment, the control circuit 42 can also compare whether the actual setting data stored in the first non-volatile memory 43 and the current setting data stored in the second non-volatile memory 44 are consistent with each other with the aforementioned buffer in step S02, and the description thereof is omitted.
In summary, according to one embodiment of the server of the present disclosure, regardless of whether the manager stores the current setting data corresponding to the actual setting data of the near-end server by the cloud server or stores the current setting data corresponding to the actual setting data of the server by the nonvolatile memory of the baseboard management controller, the server can ensure that both the two are consistent, so that the manager does not refer to the erroneous current setting data (for example, the current setting data including the first current setting before updating) inconsistent with the actual setting data, that is, the manager can perform further setting on the server according to the current setting data which is synchronous and correct with the actual setting data in real time.
Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, but rather is capable of modification and variation without departing from the spirit and scope of the present invention as defined in the appended claims.
