Problems solved by technology

Since the files are burned into the disc sequentially, it may cause unnecessary file division operations, that is, the size of a certain file is smaller than the total available capacity of the disc, but at this time the remaining capacity of the disc is smaller than the file size, and the file needs to be divided at this time. Eliminates the complexity of file burning management
This also slows down the writing speed of the optical disc storage system as the files are burned sequentially to the disc

Embodiment 1

[0035] figure 2 The flow of the method for parallel recording of massive files provided by the embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0036] The method for parallel recording of massive files provided in this embodiment includes:

[0037] Step S201 , acquiring the file set in the access buffer, sorting and dividing according to file size to obtain sub-files, and sorting the sub-files in descending order to generate a new file set.

[0038] This step implements file segmentation. In the optical disc storage system, the front-end host writes the files to be burned into the access buffer through the controller. In this step, firstly, the file set is taken out from the access buffer, and then the files in the file set are divided according to requirements to obtain sub file. The subfiles are then sorted to produce a new set of files.

[0039] Step S202. Obt...

Embodiment 2

[0047] image 3 The flow of the method for parallel recording of massive files provided by the embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0048] The method for parallel recording of massive files provided in this embodiment includes:

[0049] Step S301, obtain the file set from the access buffer, assign a unique file number to the files in it, record the position of the file in the global directory tree, and add the position relationship into the global directory table.

[0050] The access buffer stores the files imported from the front-end host, forming a file set FSET. In this implementation example, the hierarchical structure of the file set FSET in the global directory tree is as follows Figure 4 shown. Assign a unique file ID to the files in FSET and record the location of the files in the global directory tree, and add their relationship to the global ...

[0074] Figure 10 The structure of the massive file parallel recording device provided by the embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0075] The massive file parallel recording device provided in this embodiment includes:

[0076] The file splitting unit 101 is used to obtain the file set in the access buffer, sort and split according to file size to obtain sub-files, and arrange the sub-files in descending order to generate a new file set;

[0077]The sub-file adding unit 102 is configured to obtain the attribute information of the allocated disc set, read the remaining available capacity of the disc in the allocated disc set in order from large to small, and add a sub-file no larger than the remaining available capacity to the corresponding disc file collection, and update the remaining available capacity of the disc until all sub-files are added;

Abstract

The invention is suitable for the technical field of data storage, and provides a mass file parallel burning method and device. The method includes the step of file segmentation, the step of sub-file addition, the step of threshold value judgment and the step of data burning. The invention provides a file management and parallel burning scheme based on an optical disc storage system. In the scheme, files in the optical storage system can be automatically organized and distributed, a file set is distributed to each optical disc, and the aim of enabling multiple optical disc drives to simultaneously work so as to conduct parallel data burning is achieved.

Description

technical field [0001] The invention belongs to the technical field of data storage, in particular to a method and device for parallel recording of massive files. Background technique [0002] In the era of big data, the growth rate of data volume continues to increase, which in turn puts enormous pressure on storage system capacity and performance. Considering that more and more important data need to be stored for a long time, CD storage is a cheap way to store data for a long time. An optical disc storage system is a computer device that accesses data from an optical disc through an optical disc drive. The optical disc drive can access the data on the optical disc medium, and realize data communication with the host system through the data interface. The CD-ROM driver with the CD-RW function is called a CD-RW driver. Data files need to be burned into a recordable disc through a disc burning drive to realize data preservation. [0003] Existing optical discs are of var...
