GB/T 46352-2025Information technology - Technical requirement for distributed storage protocol interconnection (English PDF)

3.1 Distributed storage

A data storage technology that integrates storage space resources distributed across multiple machines through a network to form a virtual storage device.

[Source. GB/T 36074.3-2019, 3.17]

3.2 storage protocol

Rules and methods for transferring, accessing, and storing data between hosts and storage devices.

Note. The storage protocols in this document refer to file storage protocols (NFS, SMB/CIFS, POSIX file operation related interface specifications) and object storage protocols.

Distributed storage protocols include S3, SWIFT, and HDFS, which are primarily used in unstructured data applications.

3.3

A technology for ensuring semantic compatibility between storage protocols.

Note. To enable real-time access to a single set of data by various applications on a host across storage protocols, distributed storage provides a global single-database scalable layer based on a globally extensible data object layer.

A single-copy data sharing storage method, while simultaneously enabling access and semantic manipulation of storage protocols through unified storage protocol semantic mapping processing.

Compatible.

3.4 metadata

Data that defines and describes other data includes information such as creation time, modification time, type, and access permissions generated by the host application.

The information also includes information such as the mapping between logical and physical addresses of data generated within the distributed storage system.

[Source. GB/T 18391.1-2009, 3.2.16, with modifications]

3.5 unified metadata

Multi-protocol metadata is integrated to form information with a consistent data structure.

Note. Protocol metadata includes information such as directory (file) and bucket (object) names, sizes, times, and user owners.

3.6

Metadata objects are merged, processed, and stored according to certain rules and methods. […]
