    摘要： A fractional caching method and an adaptive contents transmitting method using the same are provided. The fractional caching method includes the steps of setting up a divided location for dividing a certain object into two parts, receiving an evict request for acquiring a space in the inside of the cache, when the evict request is transmitted, dividing a plurality of objects stored in the cache into a prefix-Object located in the head of the object and a suffix-Object located in the tail of the object from the divided location, and removing only the suffix-Object of each object, wherein the divided location is set up at a size rate that a size of the prefix-Object is in inverse proportion to the number of the destination types.

    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.

    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.
