DDS Technology

DDS TechnologyDDS Technology

Within the tape market there is a wide range of tape technologies, the question for SMB customers is which one to choose. The answer is clear - DDS/DAT continues to be the unit volume leader in the tape drive market for small and medium businesses with a current installed base of over 6 million and over 15 million DAT drives shipped since its introduction in 1989. This remarkable tape technology continues to flourish because it meets the needs of the SMB market for cost-effective, reliable backup better than any other technology available. Of the 3.5 million backup tape drives shipped in 2003, Gartner Dataquest estimates that approximately 50% were DAT drives.

Unlike AIT, VXA, ADR, SLR, DLT and SDLT, DDS/DAT is based on an open standard format for data interchange. The influential DAT manufacturers group presides over this open standard with verification processes that ensure compliance. With multiple manufacturers developing and shipping DDS/DAT products, customers benefit from increased competition, which leads to better prices, faster development and more choice.

DDS format for DAT is a helical scan format where data is written diagonally across the width of the tape. The advantage is that, by allowing subsequent tracks to have different writing angles and to overlap, a much greater capacity can be achieved for a given length of tape because no guard bands are necessary. The data format also allows for fast location of tracks and data. To achieve this, the rotating drum is tilted at a slight angle (6°) from the vertical. The drum has four heads (two write heads and two read heads), located at 90° intervals. For each rotation of the drum, two tracks are written. The read heads verify the data that has been written (recorded) and the drive rewrites if necessary. The straightness with which the track is written to tape is referred to as the linearity of the track and is critical in ensuring the data is always recoverable.

HP has been involved in the design and development of DDS drives since the beginning and applies these many years of experience to its current line of DDS products. Not only does an investment in DDS technology provide the security of a format with a history of outstanding reliability, the legacy of backward compatibility also provides the potential for future expansion without compromising your investment in the technology.

The target market for DDS/DAT continues to be direct-attach backup. In small and medium sized businesses cost of ownership, ease of use and a proven history (i.e. low risk) are paramount. DDS technology provides the capacity and performance needed in a tape backup solution for workstations and entry-level servers.

Proven Reliability

Proven ReliabilityProven Reliability

HP DDS drives have proven to be exceptionally reliable backup devices. Hardware reliability is typically measured by MTBF (mean time between failures) quoted in a number of hours at a particular duty cycle. Duty cycle is a measure of average usage per day. For example, a 12% duty cycle means the device is used an average of 3 hours per day, whereas a 100% duty cycle means that it is used 24 hours per day. A drive's predicted MTBF is calculated from a series of tests done on a large population of drives both before and after product launch.

HP's ongoing reliability improvements have recently resulted in an increase in reliability specifications for HP DAT drives based on real field data. By completing an analysis of actual MTBF using the years of data captured about HP DAT products, HP discovered that our DDS-4 and DAT 72 tape drives deliver even better reliability than was initially predicted and documented in our specifications.

The DAT QuickSpecs have now been revised to reflect the new figures:

The old specifications were:

DAT's MTBF is now typically expressed with a 100% duty cycle to make it simpler to compare to other tape formats; for example, HP's enterprise-level LTO Ultrium drives have an MTBF of 250,000 hours at a 100% duty cycle. In practice, however, unlike Ultrium drives (used 24x7 as the most popular choice for large tape libraries), few DAT drives would ever be used 24 hours a day. Using a 12% duty cycle that we believe is more typical for a DAT drive, the figure becomes an impressive 1 million hours at a 12% duty cycle.

HP DDS drives benefit from an automatic head cleaning "sweeper" that can be used during the write or read recovery procedure to dislodge debris from the tape path and recording heads and drive. This feature reduces the need to use a DDS cleaning cartridge for manual cleaning.

Intelligent cleaning determines the cleaning provided by a cleaning cartridge when loaded by monitoring the drive performance when in use. If the drive is performing well, a routine maintenance clean is performed. If the drive has degraded performance the cleaning is automatically made more robust to recover the drive to optimum performance.

USB 2.0 Interface

USB 2.0 InterfaceUSB 2.0 Interface

HP DAT drives are available with a choice of interfaces: the standard SCSI interface where SCSI connectivity is required and the newly introduced USB 2.0 interface.

The USB (Universal Systems Bus) interface was conceived out of a need to simplify computer peripheral device connection. It has been so successful that the majority of computer systems and servers shipped today offer multiple native USB 2.0 ports.

HP is the first company to develop a native USB DDS/DAT tape drive. Where other "USB tape drives" rely on a USB converter, HP's USB interface is fully integrated with the drive and uses the SCSI command set within the USB payload. The benefit of this implementation is that it gives the drive full SCSI functionality and the flexibility of USB without the additional cost of a converter.

By offering native USB 2.0 DAT drives, HP aims to provide customers with a number of benefits:

Greater usability

Resource abundance

Low cost, reliable connectivity

Sustainable performance

HP StorageWorks DAT Drives

HP StorageWorks DAT DrivesHP StorageWorks DAT Drives

Plug-and-play connectivity- the system automatically detects and configures the tape drive. The DAT drive is installed and ready to backup in less than 60 seconds. Microsoft fully supports USB devices natively in their operating systems providing robust, secure configuration and installation wizards. Cables are easily identifiable, easy to attach without the need for thumb-screw and robust enough to ensure reliable retention.

Native USB ports are universally available in systems and servers Multiple ports ensure that port resources are widely available, reducing the conflict between devices over scarce connectors. Port expansion is easy, USB hubs can be installed to add additional ports supporting up to 127 devices on a system

By providing native USB DDS/DAT drives there is no need for customers to purchase additional host-bus adapters HP's USB 2.0 implementation benefits from the built-in reliability and failure recovery inherent in the underlying SCSI protocol USB 2.0 has multiple levels of physical error detection and recovery which ensure reliability on a par with SCSI and Fibre-channel interfaces. USB 2.0 compliance certification provides thorough, ongoing reliability and quality control. A well implemented USB network should use only USB 2.0 compliant components, including USB 2.0 certified cables.

In HP tests it has been shown that USB 2.0 can sustain the performance of an HP DDS/DAT drive at around 30MB/sec, a bandwidth that would sustain the HP DAT 72 drive operating with a compression ratio of 9:1! USB 2.0 performance provides sufficient bandwidth to support all future generations of DDS/DAT drives specified on the DAT Manufacturers Group Roadmap

Compression

CompressionCompression

DDS uses built-in hardware compression using the 'DCLZ' data compression algorithm. Data compression is host-selectable with the default that compression is turned on. Typical data compression is 2:1, but actual compression depends on the type of data being compressed and can be more or less than 2:1.
