The Digital Audio Tape DAT technology is the most prolific of all tape technologies. The DAT tape was formerly established as DDS Digital Info Storage. Over 15 million DAT drives hog been shipped in that the early products were introduced in 1989 and deeper than 6 million owing to 2000. This gives rise to a conservative estimate of a 6-million user installed base. The HP StorageWorks DAT160 tape operate is the recent edition to the DAT family. It was launched by HP in Jun 2007. The DAT-160 manage is an evolution of existing DAT technology and has still in everyday with the preceding 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 expenditure of ownership.

The HP StorageWorks DAT 160 tape has 80-GB native faculty and up to 160 GB with 2:1 counsel compression. The HP DAT-160 has a transfer ratio of 6.9 MB/sec native, over 13.8 MB/sec with 2:1 material compression. The DAT160 provides environing 160 GB backing up in under 4 hours. Higher competence can be achieved largely by using wider tape for DAT160, on the other hand all the more provides backward create and announce 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 Press-stud Catastrophe Recovery Idea when used with the meaningful software and HP ProLiant servers, allowing complete rebuild of a server from a unmarried backup tape. It too includes Single Server Edition of HP News Protector Clear backup/recovery and disaster recovery software. DAT-160 media cartridge is supported on a broad radius of operating development and backup applications.

The DAT160 media is dependable a wider story of the DAT40 media using MP Metal Particle technology 150 m in length. This is the alike type of tape as has been shipping by reason of 1994 in DAT40 cartridges. It has a proven track copy of reliability. However, in DAT160 media, wider chronicle of the tape has been used to enable bigger capacity. A DAT160 coerce accepts both sizes of media nevertheless threads them encompassing the drum in contradistinctive ways.

Transfer standard on DAT technology is decisive partly by the wrap angle (amount of tape wrapped environing the rotating helical glance at drum) and the quickness of rotation of the drum. The wrap angle of the DAT160 guide is 180 degrees compared to matchless 90 degrees for previous genesis DAT technologies, so the DAT-160 handle really makes exceeding efficient call of tape in contact with the mind to escalation transfer rate. Besides generations testament accession the drum speed.

The HP access of using independent tape threading mechanisms was the breakthrough that enabled the DAT160 impel to commit to paper and interpret DAT-72 and DAT-40 media. When the big idea of loading two deviating heights of cartridge with two contrasting tape widths was invented, HP used lenghty machine simulation techniques to example the tape threading and routing for everyone tape type. The results of these simulations indicated that the sketch concepts were both practical and yielded beneficial levels of space in allowing the replica to be successful.

The most tough objection has been accommodating all the mechanical components in the physical time available. However, using the HP morals product originate and testing methodology, the all-important mechanical solutions and enhancements keep been evolved. The robust engineering and brim in these tape guides are the keys of a happy interchange.
