Description of the Invention: [Technical Field] The present invention relates to an independent disk multiple array (10)_mapping storage device, and more particularly to a method for mapping data protection of a storage device. Also [previous technology] independent _ multiple _ (10) _ purpose is to save the phase _ data = different places in the disc player, and improve the performance of the storage sub-function, which maps such as: just 丨) make the bottle less two __ drive And in the data block where the two == the same, this is the slowest type of error tolerance in _ is the easiest way to reverse the data to the same time. And this is the method of & (4) __ is the dual controller to cooperate, although the way to sigh, please refer to the first! The figure shows that the storage device is a controller!

The synchronous storage device corresponding to the 7-mesh device controlled by the abnormal controller is synchronously updated and added to the mapping storage device 0 to show The real money of the bottle is explained by the principle of further solution = the principle of this method, and the scope of the patented towel of the present invention is provided.

The map η申一参f is shown in Figure 6, which is the process of updating the data of the synchronously-disconnected device. After the 牟 is repaired, it is necessary to start the control 1 and -1 to obtain the status information of the mapping storage device (step _ After that, check the = 1293428 device 1 data is deducted (step 6G2), to the most complete storage of the data _f_ two: the status message to find the control of the storage damage 1 " (4 will controller 1 storage device 1 add _ lose: (== paste) 'domain will be restored to the original state, as 々 5), the sample system can be restored, the material / the person will not have any effect. In -i square ί can The problem that extends to multiple controls (four) occurs, as long as the system can be added to the map at any time after the normal device is repaired: = the control of Jing Jing reaches the storage controlled by each controller = in the convenient operation by synchronous operation.

All disk devices are built Into a map storage: preparation ' _ age set _ 峨 峨 峨 峨 听 听 , , , , , , , , , , , , , , , , , , , , On the disc, the problem is that the problem is not normal, and the magnetic r managed by it will have problems. At this time, the mapping storage device becomes a reduced-order state, and the configuration label of the hanging motherboard changes. Recording another motherboard damage information storage device can still be used normally, the user's data is recorded on 1293428 that = problem disk device, nothing happens to the user. Plywood recovery After normal work, again (four) social machine board, the host does two or two normal main _ configuration slot 'and then map the storage device to the same data on the block disk, and then modify the two matching changes. For the user, there is no other (10) the same is true for the storage of the financial material. The synchronization process of the backup preparation device is used because the mapping storage device itself has a comparison to implement the mapping mechanism. The device needs to rely on the self-editing side to perform: after the complex stepping process line, the user's reading and writing does not open the first m to 1 in the back end into the second 'and then write the data every one state normal control No failure and original writing completed (Step 2 = Γ通::=_过过(四)看控制-'Through the control--:::==: No~Set (Steps • This can be _ 1 =:: 1293428 month]=Write data that is not stored in the storage device (step _, then judge data = enter = success (step 9 () 5), if successful, mark at the end of the writer's data, 9 (m 4 material writing is completed (step 9G6) 'Other reports failure and reason (steps. The configuration data of the configuration slot data block includes the storage device Id, the establishment date, the size of the writer data, the ID of the controller) And other information, etc. The method of the present invention has the following advantages: h There is no process of switching controllers, which greatly improves the reliability and security of the system, and the system does not falter when the controller fails to convert. 2. Do not use the temporary storage H' to improve the performance of the reduction and the security of the user data, even when a single control failure occurs, the manufacturer's (4) can still copy to the mapping storage device, without the intermediate buffer Reduced memory consumption. 3. Make the whole system turn to compare branches. When the problem occurs after the control is made, the controllers that have problems can be repaired.
