Description

Method and equipment for removing heat of memory board

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for removing heat from a memory board.

Background

With the development of computer technology, the requirement for stability and reliability of a server is higher and higher, and the server often provides a memory board hot plug function, so that when a problem occurs in a memory board or a memory bank thereon, the whole memory board can be removed under an operating system, then the failed memory board or memory bank is replaced, and then a new memory board is added again, so that online replacement without shutdown is realized. This action is done while the operating system is running, called memory board hot plug, including hot add and hot remove.

For a server administrator, it is desirable to obtain and view in real time how many pieces of memory, each memory serial number, and the like of the memory asset information on the server, so as to facilitate management. The conventional collection implementation method is that a Basic Input and Output System (BIOS for short) scans all memories at a server startup stage to obtain corresponding asset information, and then sends the asset information to a Baseboard Management Controller (BMC) through an interface of the BIOS and the BMC, such as a Keyboard Controller Style (KCS), and the like, and a user obtains the memory information on the server through an interface provided by the BMC.

According to the setting of the BIOS, the hot removal of the memory board is mainly realized by the following forms:

the method is completed by matching a memory hot plug driver and a System Control Interrupt (SCI) driver in an operating System with an ACPI Source Language (ASL) code in a BIOS.

When the memory board is removed, the method for acquiring the memory information comprises the following steps:

when the operating system is started, an application program is operated, the state of the current memory in the system is periodically scanned and compared with the last scanning result, when the memory board is removed to the system, the application program is compared and updated to obtain the current memory asset information, and then the current memory asset information is sent to the BMC through the KCS interface to dynamically update the memory information.

The system is limited by the supporting operating system, and different operating systems need to develop application programs under corresponding operating systems, so that the unified compatibility cannot be achieved.
