Hardware encryption of the 4th Generation Ultrium technology increases the capacity of the disk, server performance and backup speeds. When data tape drive used in the LTO-4, compresses data and encrypts it. Then write it on the LTO media. In hardware encryption of data is done at full speed and not limit the performance of tape drives. The review of the information is encrypted during data process made in writing. The data is decrypted by theLTO-4 tape drive after it is encrypted so that data can be checked on-the-fly.
Backup software or ISVs (3rd-party developers) to manage LTO4 data encryption. Key Manager or ISV application level to manage "key." The encryption process consists of 4 layers. During recovery, read operation, the information is decrypted.
The specification of the LTO has encryption technology that has the capacity and performance increases LTO-4Band version than previous generations. Linear Tape Open IBM led program of Quantum Corporation, HP, and led the specification of the LTO-4 tape format. The specification of the LTO-4 tape interoperable will ensure that the tape drives LTO-4 generation can read 3 Media LTO 2 and LTO cartridge and can record information on LTO-3. IDC research shows that as the proportion of the LTO in the market for mid-range about 82 percent.
AES-256 encryptionbeen added to the LTO-4 specification on drive level) increased level of performance from its previous version (LTO-3-Format. The LTO-3 tape drives run their operations at 80 MB / s and the LTO-4 drives with 120 MB / second. capacity of the LTO-4 cartridge is recording twice that of LTO 3 tape. The un-compressed data of 800 GB (equivalent to 300 DVD movies) LTO4 data tape recorded in. WORM capability is also supported by the format LTO WORM 4thTechnology is also supported by the format LTO3.
HP LTO-4 tape format includes outstanding and unique properties that are ideal for backup and data security. HP C7974W LTO-4 is a robust and durable tape cassette with strong base film. New technology of print head cleaning system is included in HP LTO 4 cartridge. The tape cartridge has also designed memory chip and self diagnostic technology designed for long life and outstanding durability. HP C7974W LTO-4 hasexceptional data protection feature, as it includes AES 256 encryption. This attribute provides powerful data security. HP LTO4 Cartridge can be compressed 1.6 terabytes of information to keep.
Bit density of HP C7974W band was enhanced by the innovative coating technology and robust base film. Improved bit density means that in the same physical space and more data volume can be recorded. So the HP LTO-4 tape, large amounts of data record. The track numbers were also increasedto 896th For the protection of data of 1 GB in the LTO-4 tape cartridge, it will take approximately about 8.3 per sec for fast transmission speed of 240 MB per second. The tape cartridge has the Write Once Read Many function as well.
