[0003] However, in object storage, the basic storage object size is usually 64MB or larger, which is more suitable for storing large files, such as data files above 100MB. Files, such as pictures, emails, etc., because each file also occupies a storage object, the storage utilization rate is low; in addition, there are a large number of small and medium files in the system, and the number is in the unit of billions. Among the massive data files, small and medium The reading and writing of files will generate frequent operations for the system, which has high requirements for the reading and writing performance of the system.

Abstract

The invention discloses a method and system for file management. The method includes the steps: when storing a file, a user terminal sends a file creating request to a metadata main server; the metadata main server selects a storage object for storing the file and sends metadata information to the user terminal, the metadata information including object identification information and object position information of the storage object; when the user terminal receives the metadata information, the user terminal sends a write-in request to an object server associated with the object position information; and the object server writes the file in a data block that corresponds to the object identification information, and header information of the storage object is updated. The relation between the file and the object is redefined, one object is allowed to store data blocks of one or more files, one file can store file data blocks across multiple objects, a mass of small or medium files can be effectively managed, and then a user can conveniently store the objects and apply the objects to more general application scenarios.

Description

technical field [0001] The invention relates to the field of information storage, in particular to a method and system for managing files. Background technique [0002] The object storage system is a new type of highly reliable, cross-platform and secure data sharing storage architecture following NAS (NetworkAttachedStorage, network-attached storage) and SAN (StorageAreaNetwork, storage area network). Metadata server for management. [0003] However, in object storage, the basic storage object size is usually 64MB or larger, which is more suitable for storing large files, such as data files above 100MB. Files, such as pictures, emails, etc., because each file also occupies a storage object, the storage utilization rate is low; in addition, there are a large number of small and medium files in the system, and the number is in the unit of billions. Among the massive data files, small and medium The reading and writing of files will generate frequent operations for the syste...
