20120191675 | DEVICE AND METHOD FOR ELIMINATING FILE DUPLICATION IN A DISTRIBUTED STORAGE SYSTEM - The present invention relates to an apparatus and method for eliminating duplication of a file in a distributed storage system. The apparatus and method for eliminating duplication of a file in a distributed storage system according to the present invention calculates a hash value of each chunk for an active file; calculates a secondary hash value by adding the hash values calculated for respective chunks; examines duplication of the file using the hash value of each chunk and the secondary hash value; and eliminates a duplicated file depending on a result of the examination. | 07-26-2012 |
20120197845 | APPARATUS AND METHOD FOR MANAGING A FILE IN A DISTRIBUTED STORAGE SYSTEM - The present invention relates to an apparatus and method for managing a file in a distributed storage system. The apparatus and method for managing a file in a distributed storage system calculates a retention time of the file based on at least one of a current time, a file creation time, a file modification time and a recent file inquiry time; selects the file as an archive file if the retention time of the file is larger than a predetermined reference time; and relocates an original file and some or all of copy files of the file selected as an archive file from an active server to an archive server or from an active disk to an archive disk. If the number of inquiries on the file selected as an archive file counted in a counting period is larger than a predetermined threshold value or the file is modified or changed, the original file and some or all of the copy files of the file are restored from the archive sever to the active server or from the archive disk to the active disk | 08-02-2012 |
20120203809 | APPARATUS AND METHOD FOR MANAGING A FILE IN A DISTRIBUTED STORAGE SYSTEM - The present invention relates to an apparatus and method for managing files in a distributed storage system. The apparatus and method for managing a file in a distributed storage system according to the present invention counts the number of inquiries on a file requested by a client; selects the file as a hot file if the number of inquiries counted in a certain counting period is larger than a hot file selection threshold value; and increases the number of copies of the file selected as a hot file or stores the file selected as a hot file in a storage device having a relatively good performance. | 08-09-2012 |
