Embodiment 1

[0054] see figure 1 , figure 1 It is a schematic flowchart of a method for testing the power-failure protection function of a mainboard of a storage server provided by an embodiment of the present application. Depend on figure 1 As can be seen, the test method in this embodiment mainly includes the following steps:

[0055] S101: Before the mainboard of the storage server is powered off, write the first data in the memory space of the NVDIMM through the memset2.efi command.

[0056] memset2.efi is a test tool provided by Intel. Since the memset2.efi command covers the memory space of all NVDIMMs in the storage server, that is, as long as it is the memory space of NVDIMM, the memset2.efi command will write data into the memory space of all NVDIMMs. . Therefore, writing the first data in the memory space of the NVDIMM through the memset2.efi command can make the written data cover the entire memory space of the NVDIMM, and the test coverage rate is high and can reach 100%. ...

Embodiment 2

[0065] see figure 2 , figure 2 It is a schematic flowchart of the second method for testing the power-down protection function of the mainboard of the storage server provided by the embodiment of the present application. This example is in figure 1 On the basis of the illustrated embodiment, a process of booting into the USB disk is added before step S101.

[0066] Specifically, step S106 is included: storing the memset2.efi command and the memcheck2.efi command in the USB disk.

[0067] Step S107: Enter the U disk directory under the UEFI shell.

[0068] In this embodiment, the memset2.efi command and the memcheck2.efi command are stored in the U disk, and the U disk directory is entered under the UEFI shell. When testing the power-down protection function for different motherboards, only the U disk needs to be inserted into the corresponding The interface can be tested. Therefore, using the test method in this embodiment, the test has good portability, and the test is ...

Abstract

The invention relates to a test method and system for a power-down protection function of a storage server mainboard. The test method and system are applied to a storage server supporting an NVDIMM. The method comprises the steps that before power-down of the storage server mainboard, first data is written into a memory space of the NVDIMM through an memset2.efi command; the storage server mainboard is powered down; after a certain time threshold of a time interval, the storage server mainboard is powered on again; second data in the memory space of the NVDIMM is output through an memcheck2.efi command, and the first data is compared with the second data; and if the first data and the second data are identical, it is judged that the power-down protection function of the storage server mainboard is qualified, and otherwise it is judged that the power-down protection function of the storage server mainboard is not qualified. The system comprises a data writing module, a power-down control module, a secondary power-on module, a data output and comparison module and a power-down protection function judgment module. The test method and system are high in test coverage, good in test portability, easy to operate and convenient to popularize.

Description

technical field [0001] The present application relates to the technical field of storage server power-down protection, in particular to a method and system for testing the power-down protection function of a mainboard of a storage server. Background technique [0002] A storage server is an important class of servers in servers, and it is mainly designed for data storage for specific purposes. The write cache of the storage server stores important customer data, which may be lost after a sudden power failure of the device. NVDIMM (Non-Volatile DIMM, non-volatile memory module) is an effective solution for data protection . The motherboard is an important device for data storage in the storage server. Therefore, for a storage server supporting NVDIMM, it is an important issue to test the power-failure protection function of the mainboard of the storage server to verify whether the storage server used can reliably store data. [0003] In the prior art, there are some test m...
