| 20080215710 | Contents distributing method and distributing system - According to the present invention, there are disclosed a contents distributing method and a system which permits distribution of contents held by the client to the other clients, irrespective of the operating status of the client, and allows certain billing. In this system, a plurality of storage servers storing contents held by the individual clients are arranged on a network. The client issues a contents distributing request to the corresponding storage server, and acquires the contents. The storage server inquires, when the requested contents are not held, the retrieving server, and collects the contents from the other servers holding the contents. The storage server sends a billing requests, together with the billing information, to the service use fee billing server and the contents use fee billing server. | 09-04-2008 |
| 20090063778 | Storage System and Storage System Control Method - A storage system of the present invention improves the response performance of sequential access to data, the data arrangement of which is expected to be sequential. Data to be transmitted via streaming delivery is stored in a storage section. A host sends data read out from the storage section to respective user machines. A prefetch section reads out from the storage section ahead of time the data to be read out by the host, and stores it in a cache memory. A fragmentation detector detects the extent of fragmentation of the data arrangement in accordance with the cache hit rate. The greater the extent of the fragmentation, the smaller the prefetch quantity calculated by a prefetch quantity calculator. A prefetch operation controller halts a prefetch operation when the extent of data arrangement fragmentation is great, and restarts a prefetch operation when the extent of fragmentation decreases. | 03-05-2009 |
| 20090119697 | DISTRIBUTION DEVICE, DISTRIBUTION SYSTEM, AND DISTRIBUTION METHOD - A video distribution device that has a distribution judgment reference input function and a distribution judgment function, and can set different viewing limitations for different motion picture titles. Viewing limitations set viewable scenes and unviewable scenes in one motion picture title. Since the range of viewing limitations can be dynamically generated from access history, the motion pictures can be used for promotion, such as automatically extracting popular scenes for limited release. A viewing limitation range is reasonably decided based on more information by an interface for acquiring information such as access history from the outside. Furthermore, by embedding information of a link to another site in motion picture fragments limitedly released, viewers of the motion picture fragments can be guided to another site in which the whole motion picture can be viewed. | 05-07-2009 |
| 20090210700 | COMPUTER SYSTEM FOR JUDGING WHETHER TO PERMIT USE OF DATA BASED ON LOCATION OF TERMINAL - There is provided a computer system comprising a storage system, a terminal, a management server and the terminal, and a positioning module for identifying a location of the terminal. The terminal identifies the location of the terminal by the positioning module in a case of using the data, transmits terminal information including the identified location of the terminal to the management server; and transmits a usage request for the data to the management server. The management server judges whether or not use of the data is to be permitted based on the terminal information, and transmits permit information including usage conditions for the data to the terminal in a case where the use of the data is to be permitted. The terminal selects at least one of the volatile storage area and the nonvolatile storage area based on the usage conditions, and stores the copy of the data therein. | 08-20-2009 |
| 20100100697 | INFORMATION PROCESSING SYSTEM AND MANAGEMENT METHOD THEREOF - An information processing apparatus is provided capable of effectively utilizing resources in data transmission processes executed by a plurality of control units. A contents delivery apparatus includes network IFs, control units, disk drives used by the respective control units, and cache areas in which content data read by the respective control units from the respective disk drives is temporarily stored. Upon receiving a content data delivery request from a terminal device, the control unit of the contents delivery apparatus checks whether the requested data is present in the cache area, and if it is present (cache hit), replicates the data to the disk drive used by any one of other control units to notify a portal server allocating a delivery destination so that it is well prepared for a new delivery request from the terminal device. | 04-22-2010 |
| 20110082950 | COMPUTER SYSTEM AND COMPUTER SYSTEM INPUT/OUTPUT METHOD - Under the environment where a storage system is virtualized by Thin Provisioning technology or the like, it is difficult to statically estimate the I/O characteristics of the entire virtual volume, causing a problem that the effect of input/output control by a computer cannot be fully achieved by I/O scheduling that is based on the characteristics of a virtual volume unit. To solve the above problem, the computer system of the present invention acquires characteristics information of a storage apparatus in which there exists an actual storage area corresponding to a virtual volume storage area that is the access target when accessing the virtual volume, divides an I/O request with respect to the virtual volume by storage apparatus in a case where the I/O request spans multiple storage apparatuses, carries out I/O scheduling based on the acquired actual area characteristics information, and issues the I/O request directly to the storage apparatus in accordance with the I/O scheduling result. | 04-07-2011 |
| 20110161607 | STORAGE SYSTEM AND CONTROL METHOD THEREFOR - There is provided a storage technique for efficiently solving concentration of accesses to a particular storage medium. In the present invention, in a storage system having multiple storage media which are physically separated, duplicates of multiple blocks forming particular contents are generated, and the duplicated blocks are uniformly (in stripes) stored in storage media other than the storage medium which stores the particular contents (see FIG. | 06-30-2011 |
| 20110208910 | Storage Control Device for Storage System Provided with Storage Device Coupled to Switch Network - A plurality of storage devices are coupled with at least two switch of a switch network that is configured by a plurality of switches that transfer a packet that complies with an IP (Internet Protocol). Moreover, a storage control device is coupled with the switch network. The storage control device builds an LU (Logical Unit) that is utilized by a host device based on at least two storage devices that are coupled with different switches. | 08-25-2011 |
