Magnetic-optical-electric hybrid storage system and data acquisition and storage method thereof

Abstract

The invention discloses a magnetic-optical-electric hybrid storage system which comprises an internal memory, a solid-state disk storage area, a magnetic disk storage area and an optical disc storage area. The three storage areas logically form unified storage space and maintain a global file address mapping table to allow a user or external program to perform data addressing and access in a unified and consistent manner. During data storage, a system storage management area automatically selects appropriate physical storage positions and data arrangement manners from the three storage areas according to data access behaviors. When access modes change, the storage management are dynamically selects the appropriate physical storage position and data arrangement manner to perform necessary data migration, and the whole process is transparent to external users. The magnetic-optical-electric hybrid storage system has the advantages that the problems of an existing storage system are solved, the storage features of three storage equipment are reasonably utilized, and data storage efficiency and resource utilization rate are increased.

Description

technical field [0001] The invention belongs to the technical field of hybrid storage, and more specifically relates to a magneto-optical hybrid storage system and a data acquisition and storage method thereof. Background technique [0002] With the rapid development of the Internet and related applications, information resources have grown explosively, and the amount of information transmitted through the network has continued to expand. With the rapid development of information technology, the demand for information storage has increased sharply, and the demand for storage system capacity has increased significantly. [0003] Traditional storage servers are generally based on a large number of disk or optical disk libraries, and solid-state disks are used as caches to build data storage systems. For data that requires a large amount of backup and infrequent access, it has CD affinity, and CD storage is usually used; for data that is frequently read and written, it has dis...

AI Technical Summary

Problems solved by technology

Under the large amount of data storage needs of users, the types of data are ever-changing. There are not only disc-affinity data, but also disk-affinity data. A single storage device cannot fully meet the needs of all users, which will bring challenges to data management. At the same time, the unreasonable allocation of storage resources will lead to the waste of a lot of resources
