Questions & Anwsers

1. Is HP StorageWorks DAT 160 SAS Tape Drive compatible with previous generations?

The DAT 160 SAS Tape Drive still employs the same technology as previous DAT products. As such it keeps the two generation backward compatibility promise and can still read and write data to DAT 72 and DAT 40 (DDS-4) cartridges. It does this by recognizing the different tapes (wider DAT 160 and the narrower DAT 72/DDS-4).

2. Isn’t DAT 160 really an AIT or 8mm drive using 8mm tape media?

No, it is a DAT drive employing DDS technology and AIT cartridges are not supported or recognized in a DAT 160 drive. It uses DAT 160 wide media, based on existing DDS-4 media. The footprint is the same, the height of the cartridge has been slightly increased by 0.42 cm. Increasing the height dimension only and retaining the same footprint allows for easier tape handling. DAT 160 wide media still delivers the low cost durability and reliability DAT users have come to expect.

3. Why does an industry standard tape format specification ultimately benefit customers?

Organizations can no longer afford to buy products that don’t work together, that aren’t reliable and readily available. The DDS tape format provides a framework in which customers can reap all the benefits of competition: more innovation in products, lower prices, and added value features. Multiple competing manufacturers for both drive and media assure supply and value. The industry standard specification ensures seamless media interchange between different drive manufacturers.

4. Why was the HP StorageWorks DAT 160 SAS Tape Drive released at this time?

HP is committed to meeting the data protection needs of small or medium businesses (SMBs). DAT technology stands alone in delivering a balance of cost, performance and reliability. The DAT 72 has been the most popular DAT drive of all time and as such has met these needs for many years. The DAT 160 has now been released in recognition that SMB requirements have increased. HP is already working on a DAT 320 product to meet future needs.

5. Isn't this really the end of the road for DAT?

No, we have invested significant development efforts into this latest generation such that it enables a platform for future generations in line with the DAT roadmap (www.datmgm.com). HP is already investigating development of a DAT 320 Tape Drive.

6. Where can I find more information on connectivity and compatibility?

For more information on any of the following topics including system and server compatibility with HP StorageWorks DAT 160 Tape Drives, One Button Disaster Recovery (OBDR) solution, Library and Tape Tools, etc. go to http://www.hp.com/go/connect.

7. Why should I choose HP DDS media and how long can I store the tapes and still recover the data when I need it?

HP branded media undergoes regular additional testing on a batch-by-batch basis to ensure consistent high quality. Other vendors test to the DDS media specification, but HP does not stop there. HP also tests extensively in the areas of shock, vibration, and durability. For more details, please consult the HP white paper, “Media Qualification and Testing — HP Does More” on the website: http://www.hp.com/go/storagemedia. Tests have shown that if DDS tapes are stored correctly, the data retention life is at least 10 years. It seems likely that the actual data retention life is considerably longer.

8. What is the difference between DDS and DAT, and can you use DAT tapes with DDS drives?

Digital Data Storage (DDS) is the format that was developed by HP and Sony to adapt the Digital Audio Tape technology for data storage, which requires much higher data integrity. The term “DAT” is now most commonly applied to the data storage device and often used interchangeably with DDS. Although DDS and DAT are based on similar helical scan formats, DAT audio media is not of sufficient quality for data storage. DDS tape drives will reject DAT audio tapes. HP StorageWorks DAT Tape Drives require media that carries either the DDS format logo, the DAT 72 or DAT 160 logo to show that it is of the quality necessary for computer data storage.

9. Why choose a SAS interface DAT drive?

Customers purchasing a HP DAT Tape Drive with native SAS interface can benefit from: Wide availability of SAS ports - SAS interfaces are now widely available on servers and systems. With server I/O bus technology moving from PCI-X to PCI-Express (PCI-e), customers may find it difficult to obtain Parallel SCSI host bus adapters for the PCI-Express bus. Increased flexibility – SAS has the ability to connect multiple initiators, allowing the tape drive to be shared between several servers. Investment protection – this new generation interface is supported by a robust multi-vendor roadmap and already boasts a clear future out to 12GB/s.

10. Does the introduction of a SAS tape drive signal the end for SCSI?

No, in addition to offering native USB and SAS connectivity, HP remains committed to producing DAT SCSI interfaces for the foreseeable future. This widely respected interface continues to meet mainstream server requirements for performance and reliability.

Software

HP Data Protector Express Single Server Edition software and its Bare Metal Disaster Recovery option
