Figure 12. The accumulation of 450,000 hours testing on the DAT160 drive over the duration of the product development
cycle, with different revisions of the mechanism (the most thoroughly tested HP DAT drive)
cycle, with different revisions of the mechanism (the most thoroughly tested HP DAT drive)
DAT72 drive architecture was highly leveraged from DAT40 drive architecture, so less testing was
required.
Q8. The DAT160 drive will have a SAS interface as well as USB and
SCSI. Why is that required?
SCSI. Why is that required?
Parallel SCSI (Ultra 320) is being superseded by SAS interfaces on systems and servers. This trend is
being followed by the tape drive industry. In almost all ProLiant servers, parallel SCSI is being phased
out and Serial Attach SCSI (SAS) is taking its place.
HP is providing the DAT160 drive in three variants to assist users in the change over. We see SCSI
out and Serial Attach SCSI (SAS) is taking its place.
HP is providing the DAT160 drive in three variants to assist users in the change over. We see SCSI
variants being used in traditional legacy situations.
SAS DAT160 tape drives can connect either to an embedded SAS RAID controller or to a dedicated
SAS HBA.
All desktops, laptops, and servers now have more than one USB port.
So with these three connectivity options, SCSI (for installed base), SAS for future server connect, and

All desktops, laptops, and servers now have more than one USB port.
So with these three connectivity options, SCSI (for installed base), SAS for future server connect, and
USB (for universal connect), the DAT160 drive is assured to protect customers’ investment in DAT
technology.
