Abstract: A system integrates an intelligent storage switch with a flexible virtualization system to enable efficient service of file and block protocol data access requests for information stored on the system. A storage operating system executing on a storage system coupled to the switch implements the virtualization system to provide a unified view of storage to clients by logically organizing the information as named files, directories and logical unit numbers. The virtualization system is illustratively embodied as a file system having a write allocator configured to provide a flexible block numbering policy that addresses volume management capabilities, such as storage virtualization, at a finer granularity (e.g., a single block) than that of previous non-flexible storage virtualization schemes. The flexible block numbering policy also yields substantial benefits in terms of increased write efficiency and elimination of storage "hot spots", as well as a compelling point-in-time read-only data image (snapshot) mechanism.
Abstract translation: 系统将智能存储交换机与灵活的虚拟化系统集成，以实现对存储在系统上的信息的文件和块协议数据访问请求的有效服务。 在与交换机耦合的存储系统上执行的存储操作系统实现虚拟化系统，以通过以命名文件，目录和逻辑单元号逻辑地组织信息来向客户端提供统一的存储视图。 虚拟化系统被示例性地体现为具有写分配器的文件系统，该分配器被配置为提供一种灵活的块编号策略，该灵活的块编号策略以比以前的非均匀性更精细的粒度（例如，单个块）来处理诸如存储虚拟化的卷管理能力， 灵活的存储虚拟化方案。 灵活的块编号策略在提高写入效率和消除存储“热点”以及引人注目的时间点读数据映像（快照）机制方面也带来了实质性的好处。
