Description
Technical field
The present invention relates to Computer Storage Server development field, specifically a kind of method of testing of the system data protection based on DOS environment.
Background technology
On the memory device of various application systems, information is just growing at top speed in the mode of data storage, is constantly advancing the process of global IT application.The thing followed is that the demand of magnanimity information storage constantly increases.Although the memory capacity of file server and database server is in continuous expansion, can or can encounter space is being doubled and redoubled, the demand that user has stores service capacity to increase on the one hand, also wish on the other hand not affect current application when machine room accident power-off, guarantee that the data in buffer memory can not lost.Therefore storage server possesses data protection function has become an indispensable gordian technique of industry; the implementation of this technology is different; but in principle, be all that data are saved in non-volatile storage medium, there are vigorous vitality and vast potential for future development in the storage server field that is applied in of visual data defencive function.
Yet; the data protection function of storage server does not have general testing tool and method at present; because Client application is different; the operating system of using is also not quite similar; but be consistent on to the requirement of data protection; need to ensure and data cachedly when unexpected power down, can not lose, to can not impact service application during power recovery.Therefore fast and convenient checking means are seeming particularly important in R&D process fast, and method of testing based on DOS environment can improve the test duration greatly, and to platform resource demand, be also considerably less, the true application under authentication mechanism and operating system can be consistent again.Comprehensive these factors, in current storage server performance history, propose a kind of means of testing that is applicable to research and development fast and just seem very necessary.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of method of testing of the system data protection based on DOS environment is provided.
Technical scheme of the present invention realizes in the following manner, and its method of testing is as follows:
(1), the BIOS operational module of data protection pattern is set;
(2), the CPLD module of system power failure Trigger Function is provided;
(3), the battery module of mini system power supply is provided;
(4), memory read-write tool model under DOS.
The BIOS operational module that data protection pattern is set can be realized current system pattern is set is data protection pattern, and after the unexpected power down of system, realizes the write activity of data from internal memory to hard disk; After systematic electricity recovers, the data on hard disk are write back to internal memory;
Provide the CPLD module of system power failure Trigger Function to be mainly responsible for detecting system power state, while occurring if any power down situation, can notify battery to provide electric power support to the key chip of system.
Provide the battery module of mini system power supply after system meets accident power down, to carry out electric power output, meet system and complete data and from internal memory, be saved in the action of hard disk.
Under DOS, memory read-write tool model is mainly responsible for writing test data toward memory protect region, and can check the data integrity in memory protect region.
Advantage of the present invention is:
The method of testing of a kind of system data protection based on DOS environment of the present invention compared to the prior art, test gimmick based on DOS environment, the system configuration that collocation is simplified most, complete analog functuion test, reduced testing complex degree, improve testing efficiency, thereby can shorten the project development cycle; In addition; this method of testing has also been filled up a blank of data protection function test, make its development and testing field that is more suitable for storage server, and the present invention also has the features such as reasonable in design, simple in structure, easy to use; thereby, there is good use value.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of method of testing of the system data protection based on DOS environment.
Embodiment
Below in conjunction with accompanying drawing, the method for testing of a kind of system data protection based on DOS environment of the present invention is described in detail below.
As shown in Figure 1, the method for testing of a kind of system data protection based on DOS environment of the present invention, method of testing is as follows:
(1), the BIOS operational module of data protection pattern is set;
(2), the CPLD module of system power failure Trigger Function is provided;
(3), the battery module of mini system power supply is provided;
(4), memory read-write tool model under DOS.
The BIOS operational module that data protection pattern is set can be realized current system pattern is set is data protection pattern, and after the unexpected power down of system, realizes the write activity of data from internal memory to hard disk; After systematic electricity recovers, the data on hard disk are write back to internal memory.
Provide the CPLD module of system power failure Trigger Function to be mainly responsible for detecting system power state, while occurring if any power down situation, can notify battery to provide electric power support to the key chip of system.
Provide the battery module of mini system power supply after system meets accident power down, to carry out electric power output, meet system and complete data and from internal memory, be saved in the action of hard disk.
Under DOS, memory read-write tool model is mainly responsible for writing test data toward memory protect region, and can check the data integrity in memory protect region.
In the single control storage platform that is 2G at an Installed System Memory, by BIOS, protection memory size being set is that 1G(system free memory becomes 1G), pattern is data protection pattern; Restarting systems enters DOS environment, utilizes memory read-write instrument to the position of 0x40000000, to write the data of " 0xAA, 0xBB, 0xCC " three bytes; Now cut off AC power supplies, battery, by the electric power supply of adapter system critical piece, carries out data being copied to the action of hard disk from internal memory simultaneously, has copied rear system and can shut down; At this moment completed the action that data are preserved.
Need to confirm the integrality of these data below; connecting AC moves with simulation system power recovery; system starting process can move in the recovery of executing data from hard disk to internal memory; complete after recovery, system starts to DOS environment, now opens the data that memory read-write instrument is checked 0x40000000 place; if can see the data of " 0xAA; 0xBB, 0xCC " three bytes, the data protection function that can determine this system is normal.
Its processing and fabricating of method of testing of a kind of system data protection based on DOS environment of the present invention is very simple and convenient, can process to specifications shown in accompanying drawing.
Except the technical characterictic described in instructions, be the known technology of those skilled in the art.
