Patent number: 10168945Abstract: A storage apparatus includes: first storage devices; second storage devices that are lower in performance than the first storage devices; and a controller coupled to an external storage apparatus including third storage devices that are lower in reliability than the first storage devices and the second storage devices and coupled to the first storage devices and the second storage devices. The controller controls data migration between the first storage devices and the second storage devices based on an I/O frequency. When the total size of data stored for a predetermined period or more among data stored in the second storage devices is equal to or larger than a predetermined size threshold, the controller transmits the data stored in the second storage devices for the predetermined period or more, to the external storage apparatus.Type: GrantFiled: October 29, 2014Date of Patent: January 1, 2019Assignee: HITACHI, LTD.Inventors: Naoko Kumagai, Norihiko Kawakami

Patent number: 8572319Abstract: Conventionally, the fees for using services of a storage system was calculated based on the status of use or access performance of storage areas and not based on migration of data. The present invention provides a storage system in which multiple tiers composed of storage areas of various memory devices are assigned in page units and the assigned tiers are changed based on access frequency, wherein stored costs are calculated based on status of use of the storage areas constituting the tiers, and migration costs are calculated and charged based on the amount of migration of data among tiers and the I/O access counts after migration, according to which appropriate charging of cost for using the storage system is enabled.Type: GrantFiled: September 28, 2011Date of Patent: October 29, 2013Assignee: Hitachi, Ltd.Inventors: Naoko Kumagai, Tsutomu Sukigara, Tetsuya Abe

Publication number: 20110283062Abstract: To enable reduction of the data capacity while inhibiting degradation of read performance. If any of a plurality of host systems issues a request to write duplicate data as objective data which is identical to already stored data, a processor for a disk controller controls a data transfer control unit so that part of the duplicate data will be kept in accordance with a specific rule instead of entirely eliminating writing of the duplicate data.Type: ApplicationFiled: May 14, 2010Publication date: November 17, 2011Applicant: HITACHI, LTD.Inventors: Naoko Kumagai, Tetsuya Abe, Azuma Kano

Patent number: 7865942Abstract: A communication device including an access authority data managing DB device for managing access authority data with which access authority for at least one of storage area defined logically or physically in a storage device. File data stored in the storage area is defined while at least one of a user making the access and a group to which the user concerned belongs is set as a unit. A non-open WWW device controls access to the storage device on the basis of the access authority data achieved from the access authority data managing DB device in accordance with an access from a terminal device.Type: GrantFiled: August 1, 2006Date of Patent: January 4, 2011Assignee: Sony CorporationInventors: Atsuhiko Mimura, Naoko Kumagai, Hiroki Kotani

Patent number: 7159175Abstract: The present invention provides a cut-list creation system allowing a cut list to be made and edited automatically through a network at a request made by the user. The cut-list creation system comprises advertisement design terminals, a center server and a network for connecting the terminals to the server. The center server comprises a storage unit for storing video contents created by using an advertisement design terminal and a cut-list creation apparatus for creating template data of a video-content-scene list. The template data is created by extracting selected scenes from a video content stored in the storage unit in a division process carried out on the video content along the time axis. The division process is carried out by an advertisement design terminal by making accesses to the video content.Type: GrantFiled: February 28, 2003Date of Patent: January 2, 2007Assignee: Sony CorporationInventors: Makoto Ishii, Toshiki Ito, Naoko Kumagai

Patent number: 7103673Abstract: An ATM I/F for transmitting data to a data transmission destination via a communication network, a data transmission server, and a data transmission managing device for calculating a network necessary for data transmission on the basis of the data quantity of the data to be transmitted and the transmission completion time indicating the time of completion of data transmission to the data transmission destination are provided. Accounting information is generated on the basis of the calculated network band and transmission time. The data is transmitted to the data transmission destination by using the calculated network band. The data transmission to the data transmission destination is completed by the transmission completion time, and accounting information is generated. Thus, when transmitting data via the communication network, the data transmission completion time is designated in advance for data transmission.Type: GrantFiled: February 20, 2001Date of Patent: September 5, 2006Assignee: Sony CorporationInventors: Naoko Kumagai, Hiroki Kotani
