Publication number: 20220404987Abstract: A storage system performs storage tiering including a first storage device and a second storage device. The first storage device that stores data, the second storage device that stores data that is stored in the first storage device and elapses for a predetermined period of time. A storage control device that stores data in time series in the second storage device, reads the time-series data at a predetermined timing, and reorganizes the read data for each key to store the reorganized data in the second storage device and read the reorganized data from the second storage device when the data is read by the key.Type: ApplicationFiled: March 4, 2022Publication date: December 22, 2022Applicant: FUJITSU LIMITEDInventors: Ichirou SAKUMA, Yasuo NOGUCHI

Patent number: 8885282Abstract: A cell stores a plurality of magnetic tapes. A conveyance mechanism manages movement of the magnetic tapes stored in the cell. An interlock switch cam moves in a predetermined direction when a pressing force from an inner door claw is removed. An interlock switch shuts off power supply to the conveyance mechanism when the interlock switch cam moves in the predetermined direction. A disabling button moves on a moving path of the interlock switch cam by receiving an instruction from an operator and prevents the interlock switch cam from moving in the predetermined direction.Type: GrantFiled: March 19, 2014Date of Patent: November 11, 2014Assignee: Fujitsu LimitedInventor: Ichirou Sakuma

Patent number: 8238204Abstract: In order to facilitate the management of the hardware key of a library apparatus employing the LTO system, a write function of a noncontact memory (CM: cartridge memory) contained in an LTO tape cartridge is implemented in a medium carrying mechanism part of the library apparatus, and during an insertion to a tape drive, the IDs unique to a library control part and to the medium carrying mechanism part are recorded in the non-contact memory and utilized as the hardware key of an encrypting apparatus. The hardware key written once is overwritten (erased) during an ejection, thereby preventing leakage of key information.Type: GrantFiled: September 14, 2007Date of Patent: August 7, 2012Assignee: Fujitsu LimitedInventors: Yoshiharu Itou, Kinya Saito, Kenichi Utsumi, Reisuke Nakagawa, Hitomi Akiyama, Ichirou Sakuma, Hiroyasu Inagaki

Patent number: 7139147Abstract: A drive control apparatus receives an instruction from an upper unit, to mount a predetermined medium onto a predetermined drive unit. If a combination of the predetermined medium and the predetermined drive unit is determined as inappropriate, the drive control unit replies to the upper unit that the predetermined drive unit cannot be used. A combination of a medium and a drive is appropriate if both, the medium and the drive are suitable for any one of encrypted and unencrypted data.Type: GrantFiled: July 25, 2005Date of Patent: November 21, 2006Assignee: Fujitsu LimitedInventors: Mitsuru Yasue, Kinya Saito, Kenichi Utsumi, Reisuke Nakagawa, Hitomi Akiyama, Ichirou Sakuma, Hiroyasu Inagaki, Yoshiharu Itoh
