A backup and update method for active and standby management modules of a blade server

Abstract

The invention proposes a method for backing up and updating the active and standby management modules of a blade server, which can realize the redundant backup and firmware update of the active and standby management modules. Redundant backup is mainly based on the main management module. When the main management module fails, the slave management module can take over the system monitoring and management right. Once the main management module recovers, the slave management module will release the control right, and the main management module will regain the management right. . The firmware update method starts the NAT service on the blade module, establishes the NAT network mapping table, and transmits the firmware image to the slave management module through the network master management module, which can realize the unified update requirements of the master and backup management modules under the large-capacity firmware mirror. This method is particularly suitable for updating the firmware image of the active and standby management modules without affecting the normal use of the server by the user. At the same time, the redundant strategy of preemption can meet the user's consideration of hardware cost design.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a method for backing up and updating active and standby management modules of a blade server. Background technique [0002] Chip servers are widely used in high-performance computing and cloud computing services due to their high computing density, optimized deployment, resource sharing, and centralized management. It has become the main direction of server development. [0003] A blade server system usually consists of multiple blade modules, power supply and fan modules, and management modules. The monitoring and management system is the guarantee for the normal operation of the server. It is mainly divided into an in-band monitoring and management system and an out-of-band monitoring and management system. Among them, the out-of-band monitoring and management system can monitor and manage the key indicators of the server regardless of whether the server is powered on...

Problems solved by technology

However, the actual backup SMC unit often plays the role of temporarily replacing the main SMC, so the design form of full backup needs to be improved in terms of design cost and practical effect

At the same time, as the demand for monitoring and management increases, it is necessary to update and upgrade the firmware program of the SMC from time to time

At present, there are mainly three update methods: 1. Update by using special tools offline. When this method is implemented, the power of the server needs to be turned off, which will seriously affect the normal use of the server by users; 2. Log in to the module update via WEB Browser. , when this method is implemented, the user must artificially transfer the system control right to the module that needs to be updated before implementing it, which will also seriously affect the normal use of the server by the user; 3. Log in to the unified module to update through WEBBrowser, and use the master / standby management module. The serial port signal transmits the firmware image, but usually the image is relatively large, and the transmission on the serial port is not only slow in transmission rate, but also often has the problem of communication disconnection;
