Embodiment 1

[0050] Such as figure 1 As shown, the embodiment of the present invention provides a magneto-optical hybrid optical disk library, including an optical disk library controller, a solid state disk, a magnetic disk, a plurality of optical disk drives and a plurality of optical disks, and the optical disks can be placed in corresponding optical disk drives for data storage as required. Reading or burning, in which the solid-state disk is used as the metadata area. The capacity of the solid-state disk is relatively small but the reading and writing speed is fast. The storage space occupied by the metadata is small but it will be frequently accessed. Using a solid-state disk to store these will be frequently accessed. The accessed data can speed up the access speed; the disk is used as a data cache area, and the array storage of the disk is used as a data cache to provide users; and the optical disc can reliably store data for up to 50 years, so the optical disc is used as a long-ter...

Embodiment 2

[0052] The embodiment of the present invention also provides a management method of a magneto-optical hybrid disc library, including:

[0053] One or more local file systems are established on the whole of the disk and solid-state disk. The local file system is a global file mirroring volume, which is used to save the external global file view, that is, the user creates a directory in the CD library file volume view Or files, the corresponding directories and files are actually created in the global file mirroring volume.

[0054] Create one or more CD image buckets on the disk and SSD as a whole, each CD mirror bucket has a unique ID, and its capacity is the same as the physical CD capacity, and all CD mirror buckets are formatted as a bucket CD file system, such as UDF File system.

[0055] When a user creates a file on the optical disk library file volume, an index file corresponding to the file is created in the global file mirroring volume, and the index file does not ac...

Embodiment 3

[0077] Such as Figure 7 As shown, the present invention also provides a management system for a magneto-optical hybrid optical disc library, the system runs on the optical disc library controller, and the system includes a POSIX file system interface, an optical disc image barrel management module, an optical disc image management module, and a mechanical action management module, burning task management module, CD burning module;

[0078] The disc mirror bucket management module is used to create an empty disc mirror bucket, assign the ID number of the disc mirror bucket, assign the ID number of the currently used disc mirror bucket, convert the full disc mirror bucket into a disc mirror, recycle the recorded CD mirror bucket;

[0079] The optical disc image management module is used to manage the generation of the optical disc image for verification, perform cache management in units of the optical disc image, update the image position mapping table, and send the burning t...

Abstract

The invention provides a magnetic-optical-electric hybrid optical-disk library and a management method and a management system thereof. The optical-disk library includes an optical-disk library controller, a solid-state disk, a magnetic disk, multiple optical-disk drivers and multiple optical disks. The solid-state disk is used as a metadata area. The magnetic disk is used as a data cache area. The optical disks are used as a long-acting storage area. The optical-disk controller is connected with all the solid-state disk, the magnetic disk and the optical-disk drivers through high-speed data channels. The optical-disk library controller is used for virtualizing the whole optical-disk library into file volumes and controlling writing and reading of data, and is also used for providing external standard network storage interfaces. According to the optical-disk library, the characteristics of fast accessing speeds of the solid-state disk and the magnetic disk and long-acting data storageof the optical disks are combined to build a hierarchical storage system, a global file view and online data accessing of a user are provided, file data written by the user are stored in a magnetic-disk cache, metadata needing to be frequently read and written are stored in the metadata area formed by the solid-state disk, and an accessing speed of the data is increased.

Description

technical field [0001] The invention relates to the field of computer data storage, in particular to a magneto-optical hybrid disc library and its management method and management system. Background technique [0002] In the era of big data, the total amount of data continues to increase, and big data analysis technology is also improving. Big data analysis programs can mine potential value from a large amount of data, so a storage system that can save large amounts of data cheaply and for a long time is needed. Optical discs are a suitable storage medium for cheap, long-term storage of data. The big data analysis program requires the storage system to provide an online data access mode. However, there is a second-level delay in accessing CDs, and the access speed cannot meet the requirements of online access. Storage media such as hard disks must be used to ensure online access. CD-ROMs are used. To ensure long-term data storage. [0003] Blu-ray discs can reliably store ...
