Problems solved by technology

However, if the system is not powered on, the BMC cannot obtain the clock and can only use the default clock, which will cause abnormal logging (two startup times are repeated, and the logs are confused)
[0005] In the prior art, the BMC can obtain the RTC clock time of the CMC from the CMC of the whole cabinet / chassis under multi-level management. The first solution is: in each The BMC on the main board of the server sets an independent RTC clock; or, the second solution is As shown in Figure 1, the RTC chips are placed on the master and slave management boards respectively, and the RTC chips are not placed on the computing blades where each BMC is located. The master and slave CMCs and each BMC are interconnected through the network. Basically, the system time synchronization of the whole machine can be easily realized, but these two solutions not only increase the hardware cost, but also cannot realize that the system time of the equipment allocated to different customers by the bare metal server is different, and it is also impossible to realize that the CMC can change the system time according to the command of the node BMC. After synchronizing the corresponding virtual RTC time in CMC, the system time of different clients is inconsistent

Abstract

The invention provides a server BMC (Baseboard Management Controller) time management method, which comprises the following steps that: a physical real-time clock is arranged in a chassis management controller, and the chassis management controller carries out virtualization according to the physical real-time clock to generate a plurality of virtual real-time clocks; wherein the generated multiple virtual real-time clocks are mutually independent; each generated virtual real-time clock is controlled to communicate with the node BMCs in one-to-one correspondence, time is provided for the started node BMCs, the time of the corresponding virtual real-time clocks is modified according to commands of the node BMCs, time modification of the virtual real-time clocks does not affect the time of the physical real-time clocks, the invention further provides a server BMC time management device and a server BMC time management system, different equipment system time distributed to different clients by the bare metal server can be realized quickly at low cost without modifying hardware, and after the CMC synchronizes the corresponding virtual RTC time in the CMC according to the command of the node BMC, the system time of different clients is inconsistent.

Description

technical field [0001] The invention relates to the field of server time management, in particular to a server BMC time management method, device and system. Background technique [0002] The Bare Metal Server (Bare Metal Server) lease method for customers is based on the entire physical server lease, that is, the customer will lease several physical servers, and the number can be flexibly increased or decreased according to the customer's computing power needs. However, the bare metal servers of the same customer may be distributed in different locations, and conversely, each node in the same cabinet / chassis will also be allocated to different customers, and these customers may be located anywhere in the world. [0003] When BMSs are allocated to different customers, the customers may be located in different time zones / regions / countries, and the system time they use is different, or the customer may change the time due to factors such as special business requirements or tes...
