20080209144 | Storage system, a method of file data back up and a method of copying of file data - A storage system manages the total capacity of a shared storage medium to store block-basis data and file-basis data. When block data and its address are input through a fiber channel port, an input/output unit converts its data format to a data format that is internally applied by the storage system. When file data and its address are input, a file system converts its data format to a block data format internally applied by the storage system. The file system derives a file logical volume address from the received file address and translates file data to block data. A managing unit derives the address of a block logical volume from the block address delivered from the input/output unit. The managing unit translates block logical volume address or the file logical volume address to a physical address, and writes data to or reads data from the shared storage medium. | 08-28-2008 |

20090287953 | STORAGE SYSTEM - A storage system encrypts plain text from an external device and stores the cryptogram into a disk unit, decrypts stored data in the disk unit and transmits decrypted text to the external device. The plain and decrypted text must be in agreement when seen from the external device. If a failure occurs in the encrypting or decrypting process, the plain and decrypted text disagree. The storage system includes an encryption unit for encrypting first data, a decryption unit for decrypting the encrypted data into second data, and a comparison unit for comparing the first and second data. When the first and second data do not agree, the first data is encrypted by a different encryption unit and the encrypted data is decrypted into third data, whereupon the first and third data are compared. When the first and third data do not agree, a failure report is sent. | 11-19-2009 |
