摘要： 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.

摘要： 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.

摘要： A method of data placement and control in a block-divided distributed disk array is provided. At first, data to store is divided into logical blocks, and each of the divided logical blocks is further divided into a plurality of data blocks. Then, a parity block is created through performing an XOR operation on the data blocks of each logical block in a unit of a strip, and the parity block is arranged at the first block of a strip unit. Then, parity blocks are arranged at a next block of a previous logical block's the last data block through a left/right shifting for uniformly arranging the parity blocks through out all disks in order to fill an empty block between the logical blocks.
