The Digital Audio Tape DAT technology is the most prolific of all tape technologies. The DAT tape was previously known as DDS Digital Data Storage. Over 15 million DAT drives have been shipped since the first products were introduced in 1989 and more than 6 million since 2000. This gives rise to a conservative estimate of a 6-million user installed base. The HP StorageWorks DAT160 tape drive is the latest edition to the DAT family. It was launched by HP in June 2007. The DAT-160 drive is an evolution of existing DAT technology and has much in common with the previous five generations of DAT. It is estimated that there are over 6 million DAT tape drives currently installed worldwide. The DAT media tape cartridge is the Low-cost media and provides its customers the lowest cost of ownership.
The HP StorageWorks DAT 160 tape has 80-GB native capacity and up to 160 GB with 2:1 data compression. The HP DAT-160 has a transfer rate of 6.9 MB/sec native, over 13.8 MB/sec with 2:1 data compression. The DAT160 provides approximately 160 GB backing up in under 4 hours. Higher capacity can be achieved mainly by using wider tape for DAT160, but still provides backward write and read compatibility with DAT72 and DAT40 media. This can be done by having two independent threading mechanisms and tape paths inside the device.
DAT 160 supports HP StorageWorks One Button Disaster Recovery Solution when used with the relevant software and HP ProLiant servers, allowing total rebuild of a server from a single backup tape. It also includes Single Server Edition of HP Data Protector Express backup/recovery and disaster recovery software. DAT-160 media cartridge is supported on a wide range of operating system and backup applications.
