Description
Technical Field
The invention belongs to the technical field of servers, and particularly relates to a BIOS out-of-band management system and method.
Background
A Basic Input Output System (BIOS) provides an interface for a user to configure server startup parameters, turn on or off certain functions through BIOS Setup. The interface requires a user to operate through a keyboard, a mouse and a display, and although remote operation can be realized with the help of the KVM over Lan, batch operation cannot be supported in the case of large-scale deployment. Thus, some approaches to managing BIOS Setup out-of-band through BMC have emerged.
There are two types of current schemes: (1) A binary data structure is stored at the BMC, holding the value of the BIOS Setup option. The BMC allows the BIOS or user access through the network via the IPMI interface. The working mode is as follows: when the BMC is started for the first time, the BIOS packages the value of the current BIOS Setup option in a defined structure body and sends the value to the BMC for storage; after that, the user can view and modify the values of certain options through the IPMI or Web page, and the BMC marks that the data is updated; checking whether the data at the BMC is updated or not in the subsequent BIOS starting process, and if so, reading and applying the data; if the user directly modifies the value of the option through the BIOS Setup interface, the BIOS sends the updated value to the BMC, and the data stored by the BMC is updated. (2) The BMC stores a description and value data of a BIOS Setup option, and allows the BIOS and a user to access through a network through a Redfish interface. The operation is similar to that of category 1, except that the interface used is a Redfish.
The first prior art has the disadvantage: a. data structure and implementation binding: in the method, because only the binary data structure body is stored at the BMC, the BMC needs to completely bind the interface and the options when the BMC realizes the user access interface in order to meet the requirement of viewing and modifying the specified options. When a fabric expansion occurs or is transplanted to another product or platform, the BIOS and BMC are required to be subjected to a great deal of manpower for redevelopment, debugging and verification. b. Dependency and association relation among options are lost: the validity or configurability of certain options depends on the current value of certain options, and simple data structures cannot express this information. The second prior art solves the first drawback of the first prior art, but fails to solve the second drawback.
