Abstract:
PROBLEM TO BE SOLVED: To achieve a low power consumption in a RAID (redundant arrays of inexpensive disks) system using a plurality of hard disk drives. SOLUTION: Striping data 102-104 and its parity data 105 are generated from writing data and striping data 102-104 are recorded in three hard disk drives 102-103. The parity data 105 are recorded in hard disk drives 106 and 107 respectively. An auxiliary hard disk 109 is activated at proper timing and the parity data 105 are moved to there. Thus, the power consumption for one hard disk drive conventionally needed for parity data is saved. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a method that can access a Web site and acquire information from the Web site at high speed and with high reliability. SOLUTION: A content provider receives contents provided by content clients 101 to 103 as clients for providing contents, delivers the contents from a delivery source server 105 to Internet servers 116 to 119 of a plurality of Internet service providers, and stores them in free spaces. The Internet servers 116 to 119 each functions as a mirror server for providing the contents. Access to contents from a terminal 121 of a user is made to the mirror server operated by the Internet server 116, which then provides the user with the contents. In the method, the provision of contents is not via IX lines connecting the providers together (lines called a backbone to Internet exchange points). The user can thus access contents at high speed and with high reliability. COPYRIGHT: (C)2003,JPO
