Description

Management method of server device and management device thereof

technical field

The present invention relates to a server management framework, and in particular to a management method of a server device and the management device thereof.

Background technique

The current server management architecture can be roughly divided into two ways to manage, in-band and out-of-band. The in-band mode uses the standard Ethernet channel, and the managed terminal must be powered on and loaded with the operating system (Operating System, OS) before the management terminal can manage it. The out-of-band mode uses a dedicated management channel. Therefore, even if the managed end is turned off, the management end can also manage the managed end through the out-of-band mode.

For example, a general server system usually has a baseboard management controller (BMC), and the baseboard management controller can transmit the value sensed by the sensor (such as temperature, fan speed, etc.) through an out-of-band method to the management side. According to this, when the baseboard management controller of the mainboard of the managed side has an abnormality in the system, it can issue an out-of-band identification with the Internet protocol (Internet Protocol, IP) address (hereinafter referred to as the network address) of the baseboard management controller. The platform event trap (Platform Event Trap, PET) message of the information is sent to the management side, and this message includes information such as the cause of the problem.

However, the server management software in the existing management terminal mainly uses the network address of the operating system or the computer name (hostname) as the identification information of the management target, so this information cannot be updated to the server object through an out-of-band method.

Detailed ways

The existing software for managing the server mainly uses the network address of the operating system or the computer name (hostname) as the identification information of the management target, so the out-of-band information cannot be updated to the server object. Accordingly, the present invention proposes a management method of a server device and its management device, so that the out-of-band information can be updated to the server object of the management device.

FIG. 1A is a flowchart of a management method for a server device according to an embodiment of the present invention. This embodiment is applicable to the management terminal device. Referring to FIG. 1A , in step S105 , the server device to be managed is searched for. Here, the management device can find the server device to be managed by searching the network address of the baseboard management controller. For example, a user interface may be provided for the user to input an address search range (or a default value), so that the management device searches for the server device to be managed in the address search range. The search mode can be divided into regular search and immediate search. Moreover, the searched server devices can also be listed in the user interface for the user to choose. Generally speaking, the BMC of the server device has a network interface card, so that the management device can search for the server device to be managed by searching the network address of the BMC.

Next, in step S110, the network address of the BMC is received from the BMC of the server device. For example, a packet is received from the BMC of the server device through Remote Management Control Protocol (Remote Management Control Protocol, RMCP), and the packet records the network address of the BMC.

After that, in step S115, the identification information of the operating system of the server device is obtained according to the network address. Specifically, the network address transmitted by the BMC is the network address of the network interface card of the BMC, and the management device cannot update the information of the server device to the server object through this network address. Therefore, in this embodiment, the management terminal device obtains the identification information of the operating system according to the network address of the BMC. Here, the identification data is, for example, the network address used by the operating system of the server device or the host name of the server device.

For example, a comparison table can be set in the management terminal device, and the network address and its corresponding identification data are recorded in the comparison table in advance. Alternatively, a user interface may be provided for the user to input identification data corresponding to the network address. In addition, identification information may also be recorded in a packet carrying the network address of the baseboard management controller. For example, when the server device is turned on, identification information such as network address or host name of its operating system can be stored in the baseboard management controller. When the management device intends to manage the server device, the baseboard management controller transmits a packet including the network address of the baseboard management controller and its corresponding identification data to the management device through the remote management control protocol. Accordingly, the management device can obtain the corresponding identification data from the group.

After the identification information is obtained, as shown in step S120, the network address of the BMC is bound to the identification information. After that, in step S125, the out-of-band message received from the BMC is updated to the server object according to the identification information (such as the network address of the operating system). Specifically, when the server device is included in the management, the network address of the baseboard management controller can be updated to the server object, and the destination of the out-of-band message is set to this management device, and then the out-of-band message Then it can be sent to the management device.

Please note that each step in the above process is only to illustrate an embodiment of the present invention, and is not a limitation of the present invention. In other embodiments, the method may further include other intermediate steps or several steps may be combined into a single step, which also falls within the scope of the present invention. For example, please refer to FIG. 1B , which shows the detailed steps of the above step S125. As shown in FIG. 1B , in step S131 , analyze the out-of-band message to obtain the network address, sensor type, and event type of the BMC. Next, in step S133, the status of the server device is determined according to the event type. Finally, in step S135, the status of the server device is updated to the server object according to the identification information.

Another example is given below to illustrate the architecture of the server management system.

FIG. 2 is a block diagram of a server management system according to an embodiment of the present invention. Referring to FIG. 2 , the server management system 200 includes a management device 210 and a server device 220 , and the server device 220 is managed by the management device 210 . The management device 210 includes a management engine 211 , an analysis unit 213 , a search unit 215 and a binding unit 217 . The server device 220 includes a hypervisor 221 and a baseboard management controller 229 , and the hypervisor 221 includes a management agent 223 , an event log 225 and a monitoring agent 227 .

Generally speaking, in the server device 220, when the application program or the hardware is abnormal, the monitoring agent 227 will write the relevant information into the event log (Event Log) 225. The management agent program 223 will periodically check the event log 225 to see if there is any message to be monitored, and return the message with the computer name (or the network address of the operating system) as the identification information to the management of the management terminal device 210 in an in-band manner. The engine 211 is used to update the state of the server device 220 (ie, the server object) in the database of the management device 210 . Therefore, when the server device 220 is not powered on or fails, the out-of-band message can be sent to the management device 210 through the baseboard management controller 229 . The components of the management terminal device 210 are introduced one by one below.

In the management device 210, the search unit 215 is used to search for a server device (for example, the server device 220) to be managed, and receive the network address of the baseboard management controller 229 from the baseboard management controller 229 of the server device 220 . In addition, the search unit 215 can also be used to add a server object. That is to say, when the search unit 215 brings the server device 220 into management, a new server object can be added, and the network address of the baseboard management controller 229 can be updated to the server object.

The binding unit 217 is used for obtaining the identification information of the operating system of the server device 220 according to the network address of the BMC 229 , and binding the network address with the identification information. In addition, the binding unit 217 can also be used to query a comparison table to obtain identification information corresponding to the network address. Alternatively, the binding unit 217 obtains the network address and the identification information of the operating system of the server device 220 according to the packet received by the search unit 215 .

The management engine 211 is used for updating the out-of-band message received from the BMC 229 to the server object according to the identification information.

In this embodiment, the analysis unit 213 of the management terminal device 210 is used to analyze the out-of-band message to obtain the network address, sensor type and event type of the baseboard management controller 229, and determine the status of the server device 220 according to the event type. status, so that the management engine 211 updates the status of the server device 220 into the server event according to the identification information.

Here, the out-of-band message is an example of a Platform Event Trap (PET) message. When the analysis unit 213 receives the PET message, it analyzes the PET message. The PET message includes the network address of the BMC 229 used to transmit the PET message, and the sensor type and event type monitored by the BMC 229 . The sensor type is, for example, a fan sensor, the power sensor, etc., and the event type is, for example, a rotational speed event or a temperature event. Taking the sensor type as a fan sensor as an example, the corresponding event type is a speed event. The analysis unit 213 analyzes the PET message to know the current status of the server device 220 .

FIG. 3 is a state machine diagram according to an embodiment of the present invention. Please refer to FIG. 3 , the state 310 represents that the server device 220 is in a healthy state (indicated by "H"), the state 320 represents that the status of the server device 220 has turned on an alarm (indicated by "W"), and the state 330 represents the server device The state of 220 has reached a critical point (indicated by "C").

In this embodiment, when the state in the server object is state 310, if the received event state is "W", the state in the server object will change to state 320; if the received event state is "C ”, the state in the server object transitions to state 330.

When the state in the server object is state 320, if the received event state is "W", then the state in the server object is also state 320; if the received event state is "C", then the state in the server object The state of will transition to state 330. In addition, if the status of the received event is "Cancel" (for example, the rotation speed has returned to normal), the status in the server object will change to status 310 .

When the state in the server object is state 330, if the received event state is "C" or "W", then the state in the server object is also state 330. In addition; if the status of the received event is "cancel" (for example: the rotation speed has returned to normal), the status in the server object will change to status 310 .

In addition, in other embodiments, taking the event state as a rotational speed event as an example, it can also be set that when the rotational speed is less than the first threshold value, the state in the server object is "H"; when the rotational speed is greater than the first threshold value, the server object The state in the object is "W"; when the speed is greater than the second threshold (the second threshold is greater than the first threshold), the state in the server object is "WW"; when the speed is greater than the third threshold, The status in the server object is "C". When the current state is "WW", the state will change from "WW" to "W" when the rotational speed is less than the second threshold and greater than the first threshold. When the rotational speed is less than the first threshold value, the state changes to "H". This is just an example, not a limitation.

Accordingly, the analysis unit 213 resides in the management device 210 and is responsible for receiving the out-of-band message and analyzing the information, so that the management engine 211 can update the out-of-band message to the server object.

In summary, the present invention can receive and bind in-band messages (for example: messages with the computer name or network address of the operating system as identification information) and out-of-band messages (for example: with the network address of the baseboard management controller as identification information) information), so that the server device can be managed both in-band and out-of-band.

Although the present invention has been disclosed as above with the embodiments, it is not intended to limit the present invention. Those skilled in the art can make some changes and modifications without departing from the spirit and scope of the present invention, so the protection of the present invention The scope is to be determined as defined by the appended claims.
