背景技术 Background technique
在现代高性能计算中， 科学计算和军事应用对存储的要求越来越高， 包括 大容量、 分布式、 高性能和高可靠性。 广域网的虚拟化存储管理方式将地理上 分布的各种高性能存储系统集成为一体， 形成庞大的分布存储空间， 充分实现 资源共享，提高资源利用率，有效解决存储数据的爆炸性增长和存储管理能力 相对不足之间的矛盾。  In modern high-performance computing, scientific computing and military applications are increasingly demanding storage, including high capacity, distributed, high performance and high reliability. The WAN's virtualized storage management method integrates geographically distributed high-performance storage systems into a large distributed storage space, fully realizes resource sharing, improves resource utilization, and effectively solves the explosive growth of storage data and storage management capabilities. The contradiction between relative inadequacy.
在一个广域存储系统中， 这些海量的存储资源必须被有效的管理， 为此引 入了元数据概念。元数据是描述数据的数据， 它为系统提供对象物理位置与其 逻辑名字之间的映射， 一个逻辑文件可以对应多个物理文件副本。 此外， 元数 据还包括文件目录信息、 文件信息、 存储装置信息及相关的系统信息等等。  In a wide-area storage system, these massive storage resources must be effectively managed, and the concept of metadata is introduced for this purpose. Metadata is data that describes data. It provides the system with a mapping between the physical location of the object and its logical name. A logical file can correspond to multiple copies of physical files. In addition, the metadata also includes file directory information, file information, storage device information, and related system information.
现有技术中的数字电视前端服务器将上传的资源按文件名区分的方式存 储在 Web服务器上， 并在数据库中记录下该资源的相关信息， 所述按文件名区 分的方式可以有多种， 比如将文件名命名为上传的时间。每个资源的下载地址 记录在一个文件中， 终端机顶盒先下载记录每个资源下载地址的文件，从而得 到每个资源的下载地址并下载相关资源。 例如， 上传一些资源， 直接在发布资 源的根目录下以当前上传的时间命名：  The digital TV front-end server in the prior art stores the uploaded resources in a manner different from the file name on the web server, and records related information of the resource in the database, and the manner of distinguishing by the file name may be various. For example, name the file name as the time of upload. The download address of each resource is recorded in a file, and the terminal set top box first downloads a file that records the download address of each resource, thereby obtaining the download address of each resource and downloading related resources. For example, upload some resources and name them directly at the root of the publishing resource with the current upload time:
200909141353.zip  200909141353.zip
200909141354.zip  200909141354.zip
现有技术中的这种通过数字电视前端服务器存储资源的方式目录结构单 一，只能使用记录在数据库中的资源信息识别资源， 而不能直接在目录中识别 资源， 不方便维护管理； 同时资源无版本管理， 更新资源时总是用新上传的资 源替换旧资源， 或是直接生成一个新名字。 发明内容 In the prior art, the way of storing resources through the digital TV front-end server has a single directory structure, and the resource information recorded in the database can only be used to identify resources, and the resources cannot be directly identified in the directory, which is inconvenient to maintain and manage; Version management, always replace the old resource with the newly uploaded resource when updating the resource, or directly generate a new name.
