Problems solved by technology

However, when the storage server system receives the Power off signal and normally shuts down / powers off, the storage server system defaults that all data has been saved and will not trigger the backup function of NVDIMM, that is, the data in DRAM will not be written to NAND In FLASH, after the storage server system is shut down / powered off, the data cached in the DRAM of the NVDIMM is lost, which reduces the reliability of the storage server system

Abstract

The invention discloses a backup method of a storage server system, which comprises the following steps: after receiving a Power off command, setting an ADR register of a CPLD through a PCH; the datain the memory controller being refreshed into the DRAM of the NVDIMM by the CPLD control CPU, and the data in the DRAM being saved into the NAND FLASH after the refresh is completed. After receiving the Power off command, the invention triggers the backup function of the NVDIMM through the interaction of the south bridge PCH and the CPLD, thus ensuring that the data stored in the NVDIMM can be safely backed up and not lost when the storage server system is shut down, thereby enhancing the reliability of the storage server system. The invention also discloses a backup system of a storage serversystem, a storage server system and a readable storage medium, which have the beneficial effects mentioned above.

Description

technical field [0001] The invention relates to the field of storage, in particular to a storage server system and its backup method, system and readable storage medium. Background technique [0002] In the prior art, when the system power failure causes the storage server system to lose power abnormally, the backup function of NVDIMM (Non-Volatile DIMM, non-volatile memory module) will be triggered, that is, the entire storage server system will be saved in a short time. The current working state (including CPU, bridge chip, network card and other hardware devices and all processes in the storage server system) is refreshed into DRAM (Dynamic Random Access Memory, dynamic random access memory), and after the refresh is completed, the The data is written into the NAND FLASH to achieve permanent storage, so that the storage server system will immediately return to the previous operating state after it is powered on again. However, when the storage server system receives the ...
