    • A file level striping method adds an option for indicating whether or not to support file level striping to a file creation interface in a file system, extends an inode structure to include a last disk ID field, initializes the last disk ID when the file is created in the file system, allocates a physical block based on the last disk ID when the physical block allocation is requested at the time of file I/O request in the file system, and modifies the last disk ID value to reflect the physical block allocation made by a volume manager. An apparatus using the file level striping method includes a number of disks for storing information actually, the volume manager for logically grouping a number of disks and a file system for creating files on said logical volume and performing I/O operations.
    • 文件级条带化方法添加了一个选项,指示是否支持文件级别条带化到文件系统中的文件创建界面,扩展了一个inode结构以包含最后一个磁盘ID字段,在创建文件时初始化最后一个磁盘ID 在文件系统中,当在文件系统中的文件I / O请求时请求物理块分配时,基于最后的磁盘ID分配物理块,并修改最后一个磁盘ID值以反映物理块分配 由音量经理。 使用文件级条带化方法的装置包括实际存储信息的多个磁盘,用于在多个磁盘上逻辑分组的卷管理器和用于在所述逻辑卷上创建文件的文件系统以及执行I / O操作。

    • A hierarchical system configuration method and an integrated scheduling method for offering a multimedia streaming service on a two-level double cluster system are provided. The hierarchical system configuration method includes the steps of: determining whether one server node exists; if one server node exists, determining whether one virtual server node/specific network storing and merging block exists; and if one virtual server node/specific network storing and merging block exists, setting a system configuration mode for configuring a single virtual server node based multimedia streaming server system and determining a representative network address of a current system, wherein depending on a scale and a characteristic of the multimedia streaming service, a hierarchical multimedia streaming server system is configured into a single virtual server node based system, which is a minimum-scale, a mono-level single virtual cluster based system, which is a medium-scale, and a two-level double cluster based system, which is a maximum-scale.
    • 提供了一种用于在两层双群集系统上提供多媒体流服务的分层系统配置方法和集成调度方法。 分级系统配置方法包括以下步骤:确定是否存在一个服务器节点; 如果存在一个服务器节点,则确定是否存在一个虚拟服务器节点/特定网络存储和合并块; 并且如果存在一个虚拟服务器节点/特定网络存储和合并块,则设置用于配置基于单个虚拟服务器节点的多媒体流服务器系统并确定当前系统的代表性网络地址的系统配置模式,其中取决于比例和 多媒体流服务的特征,分层多媒体流服务器系统被配置成基于单个虚拟服务器节点的系统,该系统是最小规模的,基于单级单个虚拟集群的系统,其是中等规模的,并且 两级双集群系统,最大规模。
