Description
Technical Field
The invention relates to the technical field of servers, in particular to an online resetting device of a real-time clock of a blade server.
Background
With the rise of high-performance computing, blade servers are increasingly widely used as core hardware devices for high-performance computing. In the daily maintenance process of the blade server, a Real-Time Clock (RTC) circuit of the server needs to be reset to eliminate system faults. However, due to the characteristics of the blade system, the nodes must be powered off and unplugged to perform such operations. Individual blade systems reset the RTC in an out-of-band management manner, but the system needs to have a management network, and the system requirements cannot be met at the initial stage of batch deployment.
The blade server deployed in the current data center cannot meet the requirement of completing the action of jumping the RTC cap under the online condition of the system in the operation space. It is common practice to remove the blade cover and associated interference components after powering down the blade to reset the RTC circuit. This practice is time consuming and labor intensive.
In order to solve the problem of difficult operation, some manufacturers propose to use the out-of-band management BMC to perform the reset operation of the RTC part circuit. But the disadvantage is that when resetting, the management network of the system is required to be connected, which has a relatively strict requirement on the deployment condition in the field. In addition, the use of the out-of-band management reset RTC also requires consideration of security issues, and avoids negative effects caused by user misoperation or software instability.
