Problems solved by technology
[0005] The above conventional disk array architecture and the partition planning of each disk drive can only be applied to a single disk array, and cannot allow multiple disk arrays to coexist in one system
Moreover, since the configuration data of the array is stored in the first magnetic sector of each disk drive, the original data structure in the disk drive is often destroyed.
And after taking out the disk drive in the disk array, the data stored in it cannot be accessed by ordinary computers normally.

Embodiment Construction
[0019] First, see image 3 and Figure 4 , are respectively a block diagram of a disk management system applicable to a preferred embodiment of the present invention and a schematic diagram of the partition planning of each array disk. As shown in the figure, in the disk management system, the computer 32 can use an interface card 34 to connect multiple disk arrays and multiple independent disk drives. Wherein, the plurality of disk arrays include a first disk array 36 , a second disk array 37 and a third disk array 38 . When the computer 32 wants to access data, it can first identify which disk array or independent disk drive the address of the data belongs to, and then access the disk array or disk drive through the interface card 34 .
[0020] The above-mentioned plurality of disk arrays can be various disk arrays of the same type or different types. In the disk management system shown in the figure, the first disk array 36 is a RAID 0 array, which includes a first disk ...

Disk management method applicable to multiple disk array systems, the system includes a computer and bidirectionally connects multiple disk drive arrays and multiple independent disk drives through an interface card, the disk drives of each disk array in the system The last sector of the MCU stores an array flag and the serial number checksum of each disk drive in the same array. The computer accesses data from the disk drives through the interface card and identifies the array flag and the same array. Serial number checksum of each disk drive, the method includes: the computer detects each disk drive in the system through the interface card; reads the last volume of each disk drive; checks whether the value of the array flag is not Correct; read the serial number checksum of each disk unit in the same array; verify that the system has recorded an array to which each disk unit belongs; and record the disk unit. Identify each disk array and confirm its integrity by checking the array ID of each array disk unit in the disk system and the serial number checksum of each disk unit in the same array.
Description
technical field [0001] The present invention relates to disk management technology, especially to a disk management method applicable to multiple disk array systems, which mainly checks the array label of each array disk drive in the disk system and the serial number of each disk drive in the same array The checksum can be used to identify each disk array and confirm the integrity of each disk array. Background technique [0002] In recent years, due to the high development of information-related industries and people's increasing requirements for information product transmission speed and data security, the industry has been driven to continuously develop and improve, and develop various new product specifications. As far as computer storage systems are concerned, various disk arrays have been developed to meet the needs of use, such as RAID 0 (Redundant Arrays of Independent Drives levels 0) arrays, which provide the function of data striping (data striping), which can imp...
