Abstract
The invention relates to a data classifying automatically method of expanding virtual hard disk, it includes: the original hard disk and the expended virtual hard disk are combined to start new temporary independent disk multi array equipment; based on the parameters of shifting quantity and a speed limit set by user, the data in original independent disk multi array equipment is shift to the temporary independent disk multi array equipment; user processes the I/O requirement during the shifting data course; configuring the data classifying structure; after the data shifting, adjusting the original independent disk multi array equipment data structure to a new independent disk multi array equipment structure; releasing the temporary independent disk multi array equipment to accomplish the data automatic classify access of expanding virtual hard disk. The invention provides conflict process for expanding course, the operation can not be interrupted, configuring the data classifying structure and strengthening the slitless index effect.
Description
Technical field
The present invention relates to a kind of interconnection and transmission processing of request of storage device, particularly relate to a kind of method of expanding virtual hand disk.
Background technology
Independent magnetic disc poly array (RAID) technology allows a series of hard disk groupings, the essential data redundancy to be embodied as data protection, and for improving the data band distribution that readwrite performance forms.Common RAID array comprises at present, and Linear, RAID0 are to RAID6, and RAID10, RAID50 etc.
The increase of hard-disk capacity and the enhancing of performance all are the key issues of present independent magnetic disc poly array system, and add new hard disk in system, are the approach preferably that increases power system capacity and enhanced system performance.On the one hand, expanding virtual hand disk increases power system capacity, though can not increase the data redudancy of system; On the other hand, can obtain the more data parallel processing behind the expanding virtual hand disk, thereby increase the convenience of data retrieval and access.
The extended function of independent magnetic disc poly array allows the user under the situation of shutdown system not, adds new hard disk, carries out the expansion of RAID capacity, please refer to shown in Figure 1.New hard disk is replaced low capacity sector in the former Logical Disk, original storage block that adequately protected, and all operations all need not the shutdown, do not influence the data access of user to system.
Yet the expanding virtual hand disk function that realizes the independent magnetic disc poly array is a very stubborn problem.The classic method that increases the capacity of independent magnetic disc poly array is the data in the multiple array of first backup disk, rebuilds new jumbo logical blocks and restore data again.The technology that realizes the expanding virtual hand disk of independent magnetic disc poly array adopts hardware RAID card to realize the extended function of independent magnetic disc poly array mostly at present, as Mylex array card or the like.But these instruments are mostly restricted to the hard disk number that adds, and perhaps system must be interrupted in the process of expanding virtual hand disk.These characteristics have all been brought very big inconvenience to the user, application with the Karaoke expanding virtual hand disk, whether guard system is not play in online mode, the necessary former hard disk of initialization of the process of expanding virtual hand disk, store the reformation of block again, and system must handle lot of data migration and complicated user's request, not only inconvenience concerning the user, also must separate retrieval for data retrieval (song search) at the expansion sector, can't reach the demand of data automatic classification access, remove nonsystematic and supported to expand the built-in function of sector integration, so, this hard disk with slit expands, and often causes the inconvenience of user's data retrieval, can't reach the requirement of gapless expanding virtual hand disk.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method of expanding virtual hand disk, the virtual hard disk that expands loads with the extended mode of gapless, provide a conflict to handle for the expansion process, do not cause operating process to be interrupted, except that being configured according to built-in unified data qualification structure, the function of expanding data classification also is provided, strengthens the recall precision of gapless.
To achieve these goals, the invention provides a kind of method of expanding virtual hand disk, its characteristics are that this method comprises the following steps:
Former hard disk and expanding virtual hand disk are merged the new interim independent magnetic disc poly array equipment of opening;
The migration amount and the speed limit parameter that are provided with according to the user, with the data migtation on the former independent magnetic disc poly array equipment to this interim independent magnetic disc poly array equipment;
Ask to conflict processing at user I/O to hard disk in the migration data process;
Carry out data configuration according to built-in unified data qualification structure;
After the pending data migration finished, adjusting this former independent magnetic disc poly array device data structure was a new independent magnetic disc poly array device structure; And
Should discharge by interim independent magnetic disc poly array equipment, finish expanding virtual hand disk.
The method of above-mentioned expanding virtual hand disk, its characteristics are that this conflict is handled and also comprised the following step:
Intercept and capture user's request;
When this former independent magnetic disc poly array equipment is being expanded, the termination address of calculating request according to the start address and the length gauge of this user request;
If the termination address of this user's request, is issued to this user's request in this interim independent magnetic disc poly array equipment in the start address of migration units less than just; And
When the termination address of this user request greater than just in the start address of migration units, if the start address of judging this user request is during greater than the termination address of current migration units, user's request is issued in this former independent magnetic disc poly array equipment, otherwise, ask to add the user in the waiting list, after waiting system is finished the migration units migration, user's request is issued in the new independent magnetic disc poly array equipment handles again.
The method of above-mentioned expanding virtual hand disk, its characteristics are that this migration amount parameter expands the hard disk operation interface by one and sets.
The method of above-mentioned expanding virtual hand disk, its characteristics are that this speed limit parameter expands the hard disk operation interface by one and sets.
Effect of the present invention, be that the virtual hard disk that expands loads with the extended mode of gapless, provide a conflict to handle for the expansion process, do not cause operating process to be interrupted, except that being configured according to built-in unified data qualification structure, the function of expanding data classification also is provided, strengthens the recall precision of gapless.
