After the MAC address request monitoring process receives the MAC address request message sent by the MAC address allocation process, it takes out an unallocated MAC address from the MAC address resource pool and returns it to the MAC address allocation process, and marks the MAC address status as allocated. Described MAC address distribution process uses IPMI order to modify the MAC address used before SMC to be this MAC address;

Then described SMC uses the same method to obtain the MAC address of BMC from the MAC address server according to the BMC quantity in the chassis, and uses the IPMI command to set the MAC address of each BMC through the IPMB bus, and the MAC address resource pool identified by the MAC address server The allocated MAC addresses will not be used for MAC address allocation.

The MAC address allocation method of the server management system of the present invention comprises the following steps:

(1) Establish a LAN connection between the server management system and the MAC address server;

(2) Start the MAC address server and server management system;

(3) After the SMC is started, manually run the MAC address assignment process on it in the serial port;

(4) The MAC address allocation process uses the default MAC address in the firmware and the management IP to request the monitoring process of the MAC address in the MAC address server in the same network segment to perform Socket communication, and sends a MAC address request command;

(5) After the MAC address request monitoring process receives the MAC address request command from the MAC address allocation process, it takes out a MAC address that has not been identified as allocated from the MAC address resource pool, and returns it through the MAC address request response Assign the MAC address to the process, and mark the MAC address as assigned;

(6) The MAC address assignment process uses the IPMI command Set LAN Configuration Parameters to set the MAC address of the SMC as the assigned MAC address identified in step (5);

(7) The SMC uses the same method to obtain the MAC address of the BMC from the MAC address server according to the number of BMCs in the chassis;

(8) The MAC address allocation process uses the IPMI command Set LAN Configuration Parameters to set the MAC address of each BMC via the IPMB bus;

(9) The MAC address allocation process exits, and the MAC address allocation process of the whole machine management system is completed.

In the step (4), when the default MAC address is invalid, the MAC address allocation process can set a temporary MAC address through the IPMI command Set LAN Configuration Parameters. This temporary MAC address can be randomly generated or can be is hardcoded into the program.

In the step (7), the BMC sends an initialization completion signal after completing the initialization process, and the SMC counts the number of BMCs in combination with the Slot ID of each BMC and the detected initialization completion signal;

The SMC acquires the MAC address of one BMC at a time through the MAC address request command, and the number of executions is determined according to the number of BMCs, without adding a new request command and corresponding request response.

The beneficial effects of the present invention are: the MAC address allocation method of the server management system reduces human intervention, improves the efficiency of MAC address allocation, and solves the problems of low efficiency of artificially setting MAC addresses and prone to errors such as MAC address conflicts, and can be easily Efficiently and uniformly allocate the MAC addresses of SMC and BMC in the server management system.

It should be noted that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

A typical server with multiple blades is equipped with a management carrier board, several computing units, and necessary components such as chassis power supply and fans. An SMC is placed on the management carrier board, and a BMC is placed on each computing unit. The SMC and the MAC address server transmit the MAC address request command and the MAC address request response through the LAN, and the SMC and the BMC transmit the IPMI setting network configuration parameter command through the IPMB bus, as shown in Figure 1.

As shown in accompanying drawing 2, described SMC distributes server management system MAC address according to the following steps:

(1) Establish a LAN connection between the server management system and the MAC address server;

(2) Start the MAC address server and server management system;

(3) After the SMC is started, manually run the MAC address assignment process on it in the serial port;

(4) The MAC address allocation process uses the default MAC address in the firmware and the management IP to request the monitoring process of the MAC address in the MAC address server in the same network segment to perform Socket communication, and sends a MAC address request command;

When the default MAC address is invalid, the MAC address allocation process can set a temporary MAC address through the IPMI command Set LANConfiguration Parameters. This temporary MAC address can be randomly generated or hard-coded into the program;

(5) After the MAC address request monitoring process receives the MAC address request command from the MAC address allocation process, it takes out a MAC address that has not been identified as allocated from the MAC address resource pool, and returns it through the MAC address request response Assign the MAC address to the process, and mark the MAC address as assigned;

The allocated MAC addresses in the MAC address resource pool identified by the MAC address server will no longer be used for MAC address allocation;

(6) The MAC address assignment process uses the IPMI command Set LAN Configuration Parameters to set the MAC address of the SMC as the assigned MAC address identified in step (5);

(7) The SMC uses the same method to obtain the MAC address of the BMC from the MAC address server according to the number of BMCs in the chassis;

Described BMC can send initialization completion signal after completing initialization process, and described SMC combines the Slot ID of each BMC and the initialization completion signal that detects and counts the quantity of BMC;

Described SMC once obtains the MAC address of a BMC by MAC address request command, determines execution times according to the quantity of BMC, need not increase new request command and corresponding request response;

(8) The MAC address allocation process uses the IPMI command Set LAN Configuration Parameters to set the MAC address of each BMC via the IPMB bus;
