"ISO IEC 24775-2:2021 Information technology — Storage management — Part 2: Common Architecture" ISO/IEC 24775-2 是一个国际标准，由国际标准化组织（ISO）和国际电工委员会（IEC）共同制定，该标准的第二部分专注于信息技术领域的存储管理，并提供了通用架构。2021年发布的第二版（ISO/IEC 24775-2:2021(E)）共有216页，旨在定义和规范存储管理的通用框架，以便于不同系统和平台之间实现兼容性和互操作性。标准的这一部分，"Common Architecture"，通常会涵盖以下几个关键知识点： 1. 存储管理：这部分内容会阐述如何有效地管理和控制存储资源，包括数据的存储、备份、恢复、性能优化、容量规划以及安全性等。它可能涉及存储硬件、软件、网络和虚拟化技术。 2. 通用架构：通用架构是指一种设计模式，旨在确保不同供应商的产品和服务能够在一个标准化的环境中协同工作。这通常涉及到接口定义、通信协议和数据交换格式。 3. 接口与API：ISO/IEC 24775-2可能会定义一套标准接口和应用程序编程接口（API），使得不同的存储管理系统能够通过这些接口进行通信，从而实现数据的无缝迁移和管理。 4. 操作与监控：标准可能包含对存储系统进行操作和监控的标准方法，以确保服务质量和可用性。这可能包括性能指标、报警机制和故障恢复策略。 5. 安全与隐私：在存储管理中，数据的安全性和隐私保护是至关重要的。标准可能涵盖了数据加密、访问控制、审计日志和合规性要求等方面。 6. 兼容性和互操作性：为了促进不同系统之间的协同工作，该标准将明确指定一系列兼容性测试和互操作性要求，以确保产品遵循标准规定。 7. 灵活性和扩展性：通用架构应考虑到未来技术的发展和存储需求的变化，因此可能会强调设计的灵活性和可扩展性，允许添加新的功能或支持新的存储技术。 8. 参考模型：标准可能提供一个参考模型，用以描述存储管理系统的各个组件及其相互关系，帮助开发者和实施者理解整个系统的结构。这个标准对于IT行业，尤其是存储解决方案的开发者、数据中心管理员、系统集成商以及任何需要处理大量数据的组织来说，具有很高的实用价值。它可以帮助他们构建更高效、更安全、更易管理的存储环境，并确保其符合国际最佳实践。
