Substrate management controller address management method and servo system

The present invention relates to a system and method for processing electronic digital data, in particular to a server system management device for processing interconnection or transmission requests and a server address acquisition and storage management method.

In the current server cabinet, the baseboard management controller (BMC: Baseboard Management Controller, hereinafter referred to as BMC) of each local server is an important component for monitoring and managing the overall status of the server. If the management personnel of the server cabinet Before connecting a remote device to the BMC of one of the local servers in the server cabinet for monitoring and management, you must first manually go to the physical server cabinet to operate the server cabinet to obtain the The BMC media access control address (MAC Address: Media Access Control Address) of multiple local servers contained in the server cabinet can then be manually obtained through the remote device to store the BMC media of each local server one by one. Take the control address and configure it to the remote device for remote monitoring and management. The current method is to manually go to the server cabinet to manually operate the server cabinet and log in to the BMC of each local server one by one. Interface to obtain the BMC media access control addresses of the local servers contained in the server cabinet.

The disadvantage of manual operation is that when the number of local servers in the server cabinet system increases or when multiple server cabinets (hundreds or thousands) are to be managed by remote devices, a lot of manpower and time will be required to perform manual operations. Obtain and additionally record the data of the BMC media access control address corresponding to each local server, and perform configuration management from the remote device one by one. It is more error-prone to manually obtain and record a large amount of data. Therefore, the existing server cabinet The architecture and the method for obtaining the BMC media access control address of the local server have the disadvantages that the data acquisition and configuration setting methods when the local server is to be managed by a remote device are complicated, time-consuming and error-prone.

Therefore, an object of the present invention is to provide a baseboard management controller address management method that can improve at least one shortcoming of the prior art.

Therefore, the address management method of the substrate management controller of the present invention is executed by a server system. The server system includes a plurality of local servers, an address distribution server electrically connected to the local servers, and an address distribution server electrically connected to the local servers.

The address allocation server communicates with the local servers, and performs dynamic host protocol allocation according to the physical address of the baseboard management controller to generate an Internet protocol address corresponding to the baseboard management controller and send it To the baseboard management controller.

The baseboard management controller transmits the media access address corresponding to the internet protocol address and the baseboard management controller to the communication server.

The effect of the present invention is that the address allocation server uses the dynamic host protocol to allocate the corresponding Internet protocol address to each baseboard management controller according to the physical address of each baseboard management controller, so that each baseboard management control The server automatically generates a message queue packet for transmission to the communication server based on the assigned Internet protocol address and respective name information, thereby saving the cost and time of manual configuration management.

The present invention is applicable to a network environment including a communication server, where the communication server supports the MQTT Protocol (MQTT Protocol: Message Queuing Telemetry Transport Protocol, or MQTT protocol), when communicating with the communication server 4 The baseboard management controller (BMC: Baseboard Management Controller, hereinafter referred to as BMC) of one of the local servers in the corresponding server cabinet system is ready and operating after the local server is powered on, the BMC will receive After a ready message sent by a platform path controller of the local server, the BMC determines that the local server is ready based on the received ready information, and the ready message triggers the BMC to execute its own The BMC firmware program automatically sends the Network Controller Sideband Interface (NCSI: Network Controller Sideband Interface) command to the platform path controller of the local server of the local server to obtain the local server The corresponding physical address, where the physical address is a media access control address (MAC address: Media Access Control address, hereinafter referred to as MAC address). In more detail, the platform path controller corresponds to a first network Module, for example, is electrically connected to the platform path controller and embedded in the platform path controller; or a host system network chip integrated with the platform path controller in the same chipset, and the BMC sends the network Controller sideband interface command to the platform path controller, then the platform path controller obtains the corresponding local server from the first network module according to the received network controller sideband interface command The media access control address is returned to the BMC, and then the BMC calculates the MAC address corresponding to the local server according to a preset rule to generate a MAC address that is different from the local server The other MAC address of the address is used as the MAC address of the BMC itself. The preset rule is, for example, adding a preset value to the last byte of the read MAC address corresponding to the local server Or multiply the default value to the implementation mode of the operation, for example, add 1 or multiply 2 to the last byte of the MAC address, and transmit the MAC address of the BMC itself to a bit address allocation The server, for example, uses a dynamic host configuration protocol (DHCP: Dynamic Host Configuration Protocol, hereinafter referred to as DHCP) server to assign the server implementation mode to the address, and then the DHCP server according to the MAC bit of the BMC The corresponding IP address is assigned to the BMC, and the BMC automatically queues up with standard messages The telemetry transmission packet format sends a name information corresponding to the BMC and the Internet protocol address assigned according to the BMC's MAC address to the communication server in the form of a standard message queue telemetry transmission packet for the remote server The automated management software of the user or remote server can connect to the communication server via the network, and then obtain the name information and MAC address of the BMC corresponding to the multiple local servers corresponding to the communication server.
