The power module supplies power to the server to make the server operate normally.

Hereinafter, the operation of the present invention will be described with reference to the components of the adaptive multi-power supply server of the present invention in the "Fig. 1". As shown in FIG. 1, the server 100 of the present invention includes a power module 110 and a management control module 130.

Each power module 110 is internally provided with a bus address.

Generally, the bus addresses of the same type of power module 110 are the same, and the bus addresses of different types of power modules 110 are not the same, but the invention is not limited thereto, for example, each power module The bus address set internally by 110 can also be different. In the present invention, the power module 110 is classified by one or more parameters of the power module 110. For example, when the power module of the power module 110 is used to classify the power module, the output of the power module 110 of the same type is used. The power output is the same, and the power output of the power module 110 is different. However, the method of classifying the power module 110 is not limited to the above. For example, the manufacturer of the power module 110 or the power module 110 may be used. The specific component classifies the power module 110.

The power module 110 is responsible for supplying power to the server 100. In general, after the server 100 is powered on, the power module 110 converts the external power received by the server into a working power source that is supplied to each component in the server 100, so that the server 100 can operate normally.

One or more power modules 110 may be disposed in the server 100, and the present invention is not particularly limited. In most embodiments, the power module 110 is usually a Power Supply Unit (PSU), but the invention is not limited thereto.

The management control module 130 is responsible for controlling the power supply module 110 to supply power to the server 100. The management control module 130 further includes a storage unit 132, a detecting unit 136, and a control unit 138.

A plurality of related information is recorded in the storage unit 132. Each associated information recorded by the storage unit 132 corresponds to a category of the power module, and each associated information includes a bus address of the power module of the corresponding category and a control protocol of the power module of the corresponding category. The control protocol included in the associated information may control the power module 110 belonging to the category corresponding to the associated information, so that the controlled power module 110 supplies power to the server 100.

In addition, in some embodiments, the storage unit 132 may store the category of the power module 110 identified by the detecting unit 136 to the identified list. In some embodiments, the storage unit 132 may store the bus address of the identified category, but the invention is not limited thereto. For example, the storage unit 132 may also store a one-to-one correspondence with the identified category. The category identifier of the relationship.

The detecting unit 136 is configured to: after the server 100 is powered on, read the bus address included in the associated information recorded by the storage unit 132, and send a detection instruction to the bus address recorded by the storage unit 132, respectively, so that the request is set. The power module 110 in the server 100 responds. Generally, the detecting unit 136 selects one bus address from the bus address recorded in the storage unit 132 one by one, and sends a detection instruction to the selected bus address, when the detecting unit 136 is not detecting. When receiving the response signal sent back by the selected bus address within a predetermined time period after the test command, the detecting unit 136 determines that the power supply mode of the category corresponding to the selected bus address is not set in the server 100. The group 110, and another bus address that has not been transmitted by the detection instruction is again selected from the bus address recorded by the storage unit 132, and the detection instruction is sent to the selected bus address again until the storage unit 132 records All bus addresses are sent before the detection command. However, the manner in which the detecting unit 136 sends the detecting command is not limited to the above.

The detecting unit 136 is also responsible for identifying, according to the bus address of the response signal, the type of the power module that returns the response signal when the response signal is returned, and reading the identified component according to the identified category to the storage unit 132. Control protocol for power modules of the category. In practice, when the detection unit 136 receives the response signal, it can determine that the response signal is addressed by the bus address. The detection unit 136 can also read the control protocol of the power module using the class of the bus address according to the bus address of the return response signal to the storage unit 132.

In some embodiments, the detecting unit 136 can detect whether there is a new power module that does not belong to the identified category during the operation of the server 100, and if the detecting unit 136 detects a new power source that does not belong to the identified category. In the module, the detecting unit 136 sends a detection command to the bus address recorded by the storage unit 132 again, so as to request the detected new power module to respond, and when the detected new power module returns a response During the signal, the detection unit 136 can identify the category of the new power module based on the bus address of the response signal that is sent back.

The control unit 138 is configured to control the power module detected by the detecting unit 136 according to the control protocol read by the detecting unit 136 corresponding to the detected type of the power module, so that the detected power module The group supplies power to the server 100.

In some embodiments, the control unit 138 may not fully control all the power modules in the server 100 when the detecting unit 136 cannot identify the category of any one of the power modules disposed in the server 100. At this time, a shutdown command is issued to suspend the operation of the server 100.

Next, an operational system and method of the present invention will be described with reference to an embodiment. Referring to FIG. 2A, a flowchart of a method for adapting multiple power sources according to the present invention will be described. In this embodiment, it is assumed that the power module 110 is classified into three categories of 460 watts, 750 watts, and 1200 watts according to the output power, but the invention is not limited thereto.

First, the user needs to first set the associated information in the management control module 130 of the server 100 (step 202). In this embodiment, it is assumed that the management control module 130 is a baseboard management controller (BMC), and the user can write three pieces of related information into the storage unit 132 of the management control module 130, where it is written into the storage unit 132. The associated information records the bus address of the power module with output power of 460 watts, 750 watts, and 1200 watts, and the control protocol of the power module with output power of 460 watts, 750 watts, and 1200 watts.

After the power module 110 is set in the server 100 (step 206), when the server is powered on, the management control module 130 can send a detection instruction to the recorded bus address, respectively, so that the request is set in the server 100. The power module 110 responds (step 220). In this embodiment, it is assumed that the management control module 130 can be detected by the process as shown in the flow of "2B". The element 136 reads the three pieces of related information recorded by the storage unit 132, and selects a bus address that has not been sent the detection command from the bus address recorded by the three pieces of related information (step 222), if the detecting unit 136 First, the bus address of the power module with an output power of 460 watts is selected, and the detecting unit 136 can send a detection command to the bus address of the power module with an output power of 460 watts (step 224). Then, the detecting unit 136 can wait for receiving the response message, and continuously check whether the time when the current detection command is sent reaches a predetermined time while waiting for the response message, if the detecting unit 136 sends the detecting time and the current time difference The predetermined time is reached, and the detecting unit 136 does not receive the response message returned by the bus address of the power module with the output power of 460 watts (step 226), and the detecting unit 136 records the information again by the three related information. In the bus address, a bus address that has not been sent the detection command is selected. In this embodiment, since the detection address is sent by the bus address of the power module with the output power of 460 watts, the detection unit 136 will select a bus address from the bus address of the power module with output power of 750 watts and 1200 watts, and then repeat the above process.

If the detecting unit 136 of the management control module 130 has sent a detection command to the bus address of the power module of the output power of 460 watts, 750 watts, and 1200 watts, but has not received any bus address. After the response signal is returned, the detecting unit 136 determines that there is no bus address that has not transmitted the detection command (step 228), which means that the detecting unit 136 cannot identify the power module in the server 100, and thus, management The control unit 138 in the control module 130 can issue a shutdown command to suspend operation of the server 100 (step 290).

Continuing back to FIG. 2A, after the detecting unit 136 in the management control module 130 issues a detecting command to the bus address, the detecting unit 136 receives the bus address for issuing the detecting command within a predetermined time. When the response message is returned, the detecting unit 136 can identify the class of the power module that returns the response signal according to the bus address with the response signal sent back (step 230). In this embodiment, after the output power of the power module disposed in the server 100 is 750 watts, the detecting unit 136 sends a detection command to the bus address of the power module with an output power of 750 watts. The bus address of the power module with an output power of 750 watts is received with a response message, and the detecting unit 136 can recognize that the power module of the power module that returns the response message has an output power of 750 watts.

Thereafter, the control unit 138 in the management control module 130 can control the power module that returns the response signal according to the control agreement corresponding to the identified category, so as to send back the response message. The power module of the number is supplied to the server 100 (step 240). In this embodiment, the control unit 138 controls the power module with an output power of 750 watts according to a control protocol corresponding to the power module with an output power of 750 watts.

If the output power of the power module disposed in the server 100 is 460 watts or 1200 watts, the detecting unit 136 sends a detection command to the bus address of the power module with an output power of 460 watts or 1200 watts. The bus address of the power module with output power of 460 watts or 1200 watts also receives a response message, so the control unit 138 can also be based on a power module with an output power of 460 watts or 1200 watts. The control protocol controls the power supply module with an output power of 460 watts or 1200 watts to power the server 100. Thus, with the present invention, regardless of the type of the power module 110 disposed on the server 100, the management control module 130 can automatically select the correct control protocol corresponding to the power module 110 to control the power supply of the power module 110. The server 100 enables the server 100 to operate normally.

In addition, as shown in the flow of "2C", after the management control module 130 controls the power supply module that returns the response signal to the server 100 according to the control protocol corresponding to the identified category (step 240), the management is performed. The storage unit 132 of the control module 130 can store the identified categories to the identified list (step 250).

The detecting unit 136 of the management control module 130 can also continuously detect the existing power module during the operation of the server (step 262), and if the detecting unit 136 detects a new power module that does not belong to the identified category. (Step 266), the detecting unit 136 may send a detection command to each bus address included in each piece of related information recorded by the storage unit 132 of the management control module 130 to request a response from the new power module (step 271), and identifying the new power module according to the bus address with the response signal (step 275). This process is similar to steps 220 through 230 described above.

If the detection unit 136 of the management control module successfully identifies the category of the new power module (step 280), the control unit 138 in the management control module 130 can control the new power module according to the control protocol corresponding to the identified category. The group supplies power to the server 100 (step 240).

If the detection unit 136 of the management control module cannot identify the category of the new power module (step 280), the control unit 138 in the management control module 130 can issue a shutdown command to suspend the operation of the server 100 (step 290). .

In summary, it can be seen that the difference between the present invention and the prior art is that the management control module sends a detection command to the bus address of each power module type, and identifies the power mode according to the bus address of the response message. After the category of the group, the technical means for controlling the power supply of the power module to the server according to the identified control protocol of the category can be solved by the technical means that the different power supplies of the prior art need to be supported by different substrates of the corresponding control protocol. The management controller performs control, resulting in a problem of too many versions of the baseboard management controller, thereby achieving a technical effect of reducing the number of different versions of the basic management controller and reducing the burden of testing.
