Compared with ISO /IEC 24775-8.2014, this document has technical differences.

The vertical single line (|) in the blank position is marked. The technical differences between this document and ISO /IEC 24775-8.2014 and the reasons are as follows.

---Regarding normative reference documents, this document has made adjustments with technical differences to adapt to my country's technical conditions and adjustments.

The situation is collectively reflected in Chapter 2 "Normative Reference Documents", and the specific adjustments are as follows.

* Replace ISO /IEC 24775-2.2014 with GB/T 36450.2-2021 which is modified to adopt international standards.

The following editorial changes have been made to this document.

--- The "Scope" chapter supplements the applicable limits of this document;

---The chapter "Normative Reference Documents" deleted ISO /IEC 24775-4.2014, because it was not cited in the text;

---In order to more intuitively display the component information of the media library, the note in 5.1.3 "System Level View" is modified, and it is adopted in the full text figure.

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.

The repository configuration file and related sub-configuration files defined in this document provide a standard Common Information Model (CIM) interface for

Monitor all aspects of deleted media libraries (including tape libraries). For libraries that support this document, any storage management plan based on this document

Standard (SMI-S) clients may discover the tape library, determine its capacity, run inventory, monitor status, move tapes, and perform other

Configure and control operation. This document also standardizes the specific life cycle and alarm indication of the library; once the client has subscribed to the alarm indication

It will be delivered asynchronously to the client.

Information Technology Storage Management

Part 8.Media Library

1 Scope

This document establishes various detailed models for monitoring on the following objects in the media library.

---Library,

---drive,

---Converter equipment,

---Slot,

---Data read and write slots,

---Small Computer System Interface (SCSI) and SCSI and Fibre Channel (FC) target ports,

---Physical tape,

---Physics package,

---Media box.

Under normal circumstances, the CIM client can monitor the normal performance and status of the above objects and give alarms, status changes and life cycles.

CIM instructions. In addition, the client can control the operation of the library media that conforms to this document.

This document is suitable for the design, development, and maintenance of the media library management architecture in distributed storage devices.

The partitioned tape library and virtual tape library will be given in subsequent versions of the file. Note that the previous version of this document was used to model the partition

The experimental sub-configuration files of the tape library and virtual tape library have been revoked, so they are omitted from the current file.
