Introduction

GB/T 36450 "Information Technology Storage Management" is a recommended standard for guiding the standardization of storage management in my country. It aims to adopt a unified standard

The quasi-management interface solves the interoperability of multi-vendor products and the management of cross-regional, multi-functional distributed storage systems. GB/T 36450

The compilation of "Information Technology Storage Management" is based on ISO /IEC 24775.Due to the long overall length and the content of it can be clearly divided into

For a relatively independent but related part, GB/T 36450 is intended to be composed of eight parts.

---Part 1.Overview. Provides a general overview of the GB/T 36450 series of standards.

---Part 2.General architecture. Contains basic information about the interface, such as security and protocols.

---Part 3.General configuration file. Contains component configuration files that can be extended to other parts of the configuration files, such as target ports and jobs

control.

---Part 4.Block equipment. Contains storage configuration files that support various forms of disk storage.

---Part 5.File system. Contains configuration files that support file systems, such as network attached storage (NAS).

---Part 6.Exchange structure. Contains configuration files that handle the interconnection of host servers and storage devices, such as switches.

---Part 7.Host element. Contains configuration files for storage software on the host server, such as disk partitions and host hardware RAID

Controller.

---Part 8.Media Library. Contains configuration files for handling removable media, such as tape libraries.

This document describes how these files are used in the file system configuration file. The purpose is to establish the autonomous management configuration of programs and equipment.

Set files, and provide core functional requirements for file data support and access.

Information Technology Storage Management

Part 5.File System

1 Scope

This document specifies the management configuration file of the autonomous (top-level) configuration file of the program and equipment, and its core function is to provide file data

Support and access. In addition, this document provides information on component configuration files (or sub-configuration files) that handle file system and management interface functions.

Configuration files, these file system and management interface functions may be used by other autonomous configuration files not included in this document.

The informative appendix to this document describes how to map storage from block storage to file system output file shares, and create these

The mechanism involved in the mapping. An overview of how the file system model works is given in Appendix A.

This file contains two autonomous configuration files.

---NAS header configuration file. This configuration file specifies the model and function of the NAS device, and the device exports the file share to the remote

The user also obtains its storage from the SAN (array device attached to the NASHead device).

---Self-contained NAS configuration file. This configuration file defines the model and function of the NAS

Out to remote users, but obtain its storage resources from the internal disk drive of the NAS device (rather than an externally connected array).

This document also specifies a large number of component configuration files. These components are used by autonomous NAS configuration files, and may also be used by other

Used in autonomous configuration files that describe the principles and service characteristics of the file system. Component configuration file included in this file (from configuration file)

as follows.

---File export (component) configuration file. This component configuration file defines the file system or

The model element of the directory, this autonomous configuration file exports the file data to the remote system.

---File export operation (component) configuration file. The component configuration file defines the elements used to model services, which are used for

Create, modify, and delete any file sharing (export file system

System or directory representation).

---File storage (component) configuration file. The configuration file of this component defines the storage model for the file system on the logical disk

Elements. The configuration file does not maintain the service of file system to logical disk mapping. These services are in the file system manual

Defined in the configuration file.

---File system (component) configuration file. The component configuration file defines the elements used in the file system model and related

Elements such as logical files, directories, and information about how the file system is addressed when it is mounted on a particular system. Relevant definition

Information services for maintaining file system configuration files are included in the file system operation configuration files.

---File system operation (component) configuration file. The configuration file of this component defines the file system service used to create, modify, and delete

The elements of the model and the elements related to it.

---File system quota (component) configuration file. This component configuration file defines various files for creating, maintaining, and reporting.

Elements of the modelling of the elements related to the quotas of the software system elements.

This document is applicable to the design, development, and management of related sub-configuration files of the file system.
