Abstract
The invention provides a design method for a stand-by power supply of a storage server. The design method has the advantages that multiple protection measures are used to avoid data loss due to power-fail. The design method comprises the following steps: at first, two power supply modules that are complemented with each other are used for redundancy power supply, and then a mainboard is divided into two identical mainboards, wherein one is used for normal work and the other one is used for data backup; once one of the two power supply modules is in power-fail, data is stored in a memory of a mirror image and is stored in hardware after power resumption, and finally, a stand-by power supply is a key for protecting data, in case of power-fail, the stand-by power supply provides power for the memory and the hardware to ensure that the data is not lost; and the data (namely data is not yet written in the hardware) in the memory is automatically stored for 72 hours to wait the power supply modules to supply power. Once the power supply modules resume normal work, the data in the memory is written in a disk array preferentially, and then the disk array starts other normal procedures.

Summary of the invention
The BBU method for designing that the purpose of this invention is to provide a kind of storage server.
The objective of the invention is to realize by following mode; The googol that prevents to bring because of the server power down through the mode of using standby power supply and mainboard mirror image is according to loss; Server uses two electric redundant power supplies, and standby power supply is placed on the centre position of two supply modules, realizes the power supply to internal memory and hard disk internal memory; System comprises mainboard mirror image function modules, the external functional module of standby power supply and hard disk internal memory function of supplying power module, wherein:
The mainboard mirror image function modules: two identical mainboards, comprise CPU and internal memory, server uses two same mainboards; An operate as normal; Another just does mirror back-up of data at ordinary times, and when a mainboard power down, another mainboard just backups; The mainboard of the treating power down continued that powers on writes hard disk, and two mainboards use two supply modules of complementary influence;
The external functional module of standby power supply: this module is that the external functional module of the standby power supply on the mainboard is put on the mainboard limit, and it is external to be used for the plug formula, and this standby power supply is simultaneously to two fast main board power supplies; When the mainboard power down; Standby power supply is supplied power to internal memory, and the data in the internal memory comprise the data that also do not write in the hard disk, will be preserved a period of time automatically; The mainboard of power down by the time re-powers continued and is written in the hard disk, and the assurance data can not lost because of power down;
Hard disk internal memory function of supplying power module: to hard disk internal memory power supply also is use same standby power supply, because of hard disk not on mainboard, so, then the hard disk internal memory is being supplied power through single line cable connection standby power supply and hard disk backboard.
The invention has the beneficial effects as follows: this method for designing uses the multiple-protection measure to prevent the loss of data that causes because of power down; At first be to use the power module redundant power supply of two complementary influences; Probability of phenomena is extremely little because cutting off the power supply appears in two power modules simultaneously, can occur hardly.Secondly mainboard is divided into two identical mainboards, one is used for normal work, and another is used to do data backup; In case a power module power down is arranged, just data are preserved first in the internal memory of mirror image, after by the time powering on once more these data are deposited in the hard disk; Be standby power supply at last, it is the key of protected data, when the power down phenomenon takes place; Standby power supply is to internal memory and the power supply of hard disk internal memory; The assurance data are not lost, and the data in the internal memory (also not writing the data in the hard disk) will be preserved 72 hours automatically, recover to wait for that power module is supplied with.In case power module recovers operate as normal, the dish battle array can preferentially write hard disk with the data in the internal memory, begins other conventional programs again.
