DAT 72 (Fifth generation DDS Tape Technology)

Fifth generation tape drive technology uses the helical scan format. Data is written and recorded in groups, where each group is a logical collection of data records physically recorded as 22 frames, each frame containing 2 tracks. The DAT 72 format is a semi-open format and data written on any HP StorageWorks DAT 72 tape drive may be interchanged directly with DAT 72 tape drives from other vendors.

Backwards Compatibility	DAT 72 tape drives are fully read and write backwards compatible with all DDS-3 and DDS-4 products from all
	licensed manufacturers.
High Reliability	HP's DDS tape technology has proven itself during more than 12 years of use as one of the most reliable tape
	technologies on the market today. DAT 72 builds on the strengths and successes of previous generations of
	DDS drives. The HP StorageWorks DAT 72 tape drive has a mean time between failure (MTBF) rating of 400,000
	hours at a 12% percent duty cycle, making it an ideal choice for small and medium businesses.
Compression	The HP StorageWorks DAT 72 tape drive as per previous generations of DDS uses the ‘DCLZ’ data compression
	algorithm. Data compression is host selectable with the default that compression is turned on.
Compatibility Testing	The HP StorageWorks DAT 72 tape drive for ProLiant is fully supported and compatible with HP ProLiant servers,
	AlphaServers and host bus adapters. This tape drive is thoroughly tested with other major brands of server,
	leading software and operating systems. The compatibility matrix shown below gives a more comprehensive
	listing of all hardware and software supported.
Rackmount	All HP DDS tape products have variants that enable the drive to be fitted into racks.
	For compatibility with ProLiant and AlphaServer systems use 3U rackmount kit (P/N 274338-B21) and internal
	drive (P/N Q1525A).
	For compatibility with HP UNIX systems and to be fitted into HP Tape Array 5300 (P/N C7508A) use Array Module
	(P/N Q1524. Order option #OD1 for Factory fitted option).
HP DDS Storage Media	HP’s test program for HP DAT 72 media is probably the most thorough and comprehensive in the industry. HP
	data cartridges must satisfy an exhaustive battery of additional tests that relate directly to real life situations,
	where real data and real businesses are at stake. Over 1 million test hours on media and drives per year ensure
	that HP data cartridges will always offer maximum reliability even in the most extreme conditions. HP
	recommends that customers always use HP branded media to ensure stress free backup and complete peace of
	mind.
