Description

Device detection method and device detection system

The present invention relates to a device detection method and a device detection system, and in particular to a device detection method and a device detection system for at least one server.

The design of the server tends to be diversified, and the configuration design of the physical device corresponding to the server is also relatively complicated. That is to say, based on different usage requirements, the design of the server will be adjusted from time to time, and the design of the hardware device will also be different. The development of the server's Baseboard Management Controller (BMC) must determine the configuration design of the physical device corresponding to the server, so that the BMC can correctly monitor and manage the server. It can be seen that how to quickly determine the physical device configuration design of the server, thereby shortening the development time of the BMC, is one of the research focuses of those skilled in the art.

The invention provides a device detection method and a device detection system, which can quickly determine the configuration design of the physical device of the server.

The device detection method of the present invention is used to detect multiple devices of at least one server. The device detection method includes selecting one of the at least one server as the selected server by the host, and scanning at least one Nth layer device of the selected server through the communication interface; recording the at least one Nth layer device The address of at least one first type device in the layer device; and at least one second type device in the at least one Nth layer device is respectively defined as a node, and at least one N+1th layer corresponding to the node The device scans, and N is a positive integer.

The device detection system of the present invention includes at least one server and a host. The at least one server each includes a plurality of devices. The host communicates with the at least one server through a communication interface. The host selects one of the at least one server as the selected server, and scans at least one N-layer device of the selected server through the communication interface, and records at least one of the at least one N-layer device. The address of the first type of device. In addition, the host defines at least one second-type device in the at least one N-th layer device as a node, and scans at least one N+1-th layer device corresponding to the node, where N is a positive integer.

Based on the above, the host records the address of the first type device among the detected N-th layer devices. The host defines a second-type device in the N-th layer of devices as a node, and scans at least one N+1-th layer device corresponding to the node. In this way, the physical device configuration of the server can be quickly determined. In addition, the development time of BMC will be shortened.

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail together with the accompanying drawings.

Parts of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. For the referenced reference symbols in the following description, when the same reference symbols appear in different drawings, they will be regarded as the same or similar components. These embodiments are only a part of the present invention, and do not reveal all possible implementation modes of the present invention. Rather, these embodiments are only examples within the scope of the patent application of the present invention.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 1 is a schematic diagram of a device detection system according to an embodiment of the present invention. FIG. 2 is a flow chart of a device detection method according to an embodiment of the present invention. In this embodiment, the device detection system 100 includes servers 110_1 - 110_3 and a host 120 . The host 120 communicates with the servers 110_1 - 110_3 through the communication interface. The host 120 may be an electronic device with a computing function. The host 120 can be, for example, an electronic device such as a desktop computer, a notebook computer, or a smart phone. The servers 110_1 - 110_3 respectively include a plurality of devices. For example, the server 110_1 includes devices 111 - 118 . For ease of description, this embodiment takes three servers 110_1 - 110_3 as an example. The number of servers in the device detection system of the present invention may be one or more, and is not limited to this embodiment. In addition, the number of devices of the server of the present invention may be multiple, and is not limited to this embodiment.

In this embodiment, the host 120 performs multiple operations based on steps S110 - S130 . In step S110 , the host 120 selects one of the servers 110_1 - 110_3 as the selected server, and scans the Nth layer devices of the selected server. The host 120 detects the N-layer device to determine the type of the N-layer device. N is a positive integer. In step S120, the host 120 records the address of the first type device. In step S130, the host 120 defines the second type of device as a node. In addition, the host 120 also scans the N+1th layer device corresponding to the node in step S130 . In other words, the host 120 also scans the N+1th layer device of the second type device connected to the Nth layer device in step S130 .

In this embodiment, the first type of device is a sensing device. For example, the sensing device may be one of a temperature sensor, a voltage sensor, a current sensor, and a speed sensor for a fan. The second type of device is a multiplexer. That is, if multiple multiplexers are detected, the host 120 defines at least one detected multiplexer as a node. The host 120 scans the next layer device corresponding to the node.

It is worth mentioning here that the host records the address of the first type of device detected. The host defines the second type device as a node and scans at least one N+1th layer device corresponding to the node. In this way, the physical device configuration of the server can be quickly determined. Therefore, the development time of the Baseboard Management Controller (BMC) can be greatly shortened.

For example, in step S110 , the host 120 selects the server 110_1 as the selected server, and scans the layer 1 devices of the server 110_1 through the communication interface. The communication interface can be, for example, an interface suitable for I2C or SMBUS. After scanning, the host 120 can know that the first layer devices of the server 110_1 are the devices 111 and 112 . The host 120 further knows that the device 111 is a first type device, and the device 112 is a second type device. In step S120 , the host 120 records the address of the device 111 . In step S130 , the host 120 defines the device 112 as a parent node (or called a root node). Next, the host 120 scans the layer 2 devices connected to the nodes in a recursive manner. That is to say, the host 120 scans the layer 2 devices (i.e., devices 113-115) connected to the node (i.e., the device 112) to determine the type of the layer 2 devices, and records the detected first type devices. address, define the second type of device as a node, and scan for layer 3 devices connected to the node, and so on.

Specifically, the host 120 determines that the device 113 is a first type device, and the devices 114 and 115 are a second type device. Therefore, the host 120 will record the address of the device 113 . In addition, host 120 defines device 114 as a first child node of a layer 2 device, and defines device 115 as a second child node of a layer 2 device. Therefore, the host 120 shuts down the device 115 through the communication interface and recursively scans for layer 3 devices (ie, devices 116 , 117 ) connected to the device 114 . Next, the host 120 shuts down the device 114 through the communication interface and recursively scans the layer 3 device (ie, the device 118 ) connected to the device 115 . In this way, the addresses of all the first type devices (ie, devices 111 , 113 , 116 - 118 ) can be quickly recorded.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 at the same time. FIG. 3 is a schematic diagram of a webpage interface according to an embodiment of the present invention. In this embodiment, the host 120 can provide a web interface 200 . The web interface 200 includes a server field 210 and a server address field 220 . The server field 210 and the server address field 220 can be edited to provide selection commands. The host 120 receives the selection command to select one of the servers 110_1 - 110_3 as the selected server. The server address can be, for example, an Internet Protocol address (Internet Protocol Address).

In this embodiment, the web interface 200 further includes a scan layer number field 230 and a scan button B1. The scan layer field 230 can be edited to provide scan layer instructions. The host 120 scans multiple devices in the selected server based on the scan layer command.

In this embodiment, the host 120 obtains the scanning layer number based on the scanning layer number instruction, and scans the devices in the scanning layer number in the selected server in a recursive manner based on the scanning layer number. For example, the user can input "2" in the scan layer field 230 and click the scan button B1. The web interface 200 is operated to provide a scan level command corresponding to a scan level equal to 2. Therefore, the host 120 obtains the scan layer number equal to 2 based on the scan layer number command. Based on the number of scan layers, the host 120 recursively scans the first layer devices and the second layer devices in the selected server.

In this embodiment, the web interface 200 further includes a BMC field 240, a file name field 250, a scan result window 260, and a download button B2. In some cases, the BMC model recorded in the BMC field 240 and the file name recorded in the file name field 250 may be preset. Therefore, the results and/or syntax of the scan result window 260 will match the firmware design of the BMC of the same model. Once the download button B2 is clicked, the filename of the scanned result will be set as the filename recorded in the filename column 250 .

In some situations, the user may decide to scan the selected server based on different BMC firmware designs. The user can input the selected BMC model into the BMC field 240 and click the scan button B1. The results and/or syntax of the scan result window 260 will match the firmware design of the selected BMC.

In some cases, the file name recorded in the file name column 250 can be modified. The user can input a desired file name in the file name column 250 .

In some embodiments, at least one of the server field 210 , the server address field 220 , the scan layer field 230 , the BMC field 240 and the file name field 250 can be designed as a drop-down menu.

Incidentally, this embodiment can use the web interface 200 to provide the device detection method and the settings of the device detection system 100 . The webpage interface 200 of this embodiment can make the user familiar with it quickly. Therefore, the webpage interface 200 of this embodiment also determines the physical device configuration design of the server more quickly, thereby shortening the development time of the BMC. In addition, the design of the scanning layer column 230 can shorten the scanning time.

In this embodiment, the scan result window 260 can display the scan result based on steps S110-S130, so as to generate a tree view of the device. The information ND1-ND3 of the second type of device (eg, multiplexer), such as address or model, is respectively recorded at each node of the tree diagram. The messages LF1 - LF5 outside the nodes are respectively the messages of the first type of devices (eg, sensors), such as addresses or models. The above-mentioned messages ND1-ND3, LF1-LF5 can be represented by text or images, respectively, for example. For example, in the first level of the tree diagram, the message LF1 corresponds to the device 111 . The message ND1 corresponds to the device 112 . In the second level of the tree diagram, the message LF2 corresponds to the device 113 . The message ND2 corresponds to the device 115 . The message ND3 corresponds to the device 114 . In the scan result window 260, the messages LF2, ND2, ND3 are connected to the message ND1 through the channel. This means that the devices 113-115 are respectively connected to the device 112. In the third level of the tree diagram, the message LF3 corresponds to the device 118 . The message LF4 will correspond to the device 116 . The message LF5 will correspond to the device 117 . In the scan result window 260, the message LF3 will be connected to the message ND2 through the channel. This indicates that device 118 is connected to device 115 . In the scan result window 260, the message LF3 will be connected to the message ND2 through the channel. This means that the devices 116 , 117 are connected to the device 114 . It can be known from this that the information displayed in the scan result window 260 can correspond to the configuration relationship of the devices 111 - 118 .

Please refer to FIG. 1 , FIG. 3 and FIG. 4 . FIG. 4 is a flowchart of a device detection method according to another embodiment of the present invention. In this embodiment, the host 120 performs multiple operations based on steps S210-S290. In step S210, the host 120 at least receives a selection instruction and a scanning layer instruction. In this embodiment, the host 120 can provide a web interface 200 . The selection command and the scan layer command can be generated through operations on the web interface 200 . In step S220, the host 120 selects the selected server based on the selection instruction. In step S230 , the host 120 initializes the N value so that the N value is equal to 1, and scans the Nth-tier devices (ie, the first-tier devices) in the selected server. Step S230 is executed after the scan button B1 is clicked. In step S240, the host 120 records the address of the first type device in the Nth layer device. In step S250, the host 120 defines the second type device among the N-th layer devices as a node.

In step S260, the host 120 determines whether the value of N is equal to the number of scan layers based on the scan layer number instruction. When the N value is not equal to the number of layers to be scanned, the host 120 adds 1 to the N value in step S270 , and scans the Nth layer devices connected to the node in step S280 . That is, the host 120 scans the layer 2 devices connected to the second type devices in the layer 1 devices. Next, go to step S240. Therefore, the host 120 performs a recursive operation based on the step loop formed by steps S240 to S280 until the value of N is equal to the number of scanning layers.

When the host 120 determines in step S260 that the value of N is equal to the number of scanning layers, the host 120 will end scanning and archive in step S290.

To sum up, the host of the present invention records the address of the first type device among the detected N-th layer devices. The host defines a second-type device in the N-th layer of devices as a node, and scans at least one N+1-th layer device corresponding to the node. In this way, the physical device configuration of the server can be quickly determined, thereby shortening the development time of the BMC. In addition, the present invention can use the web interface to provide the device detection method and the configuration of the device detection system. The web page interface of this embodiment can make the user quickly familiar with it. Therefore, the webpage interface of this embodiment can more quickly determine the configuration design of the physical device of the server.
