The SuperDLT (SDLT) tape
drives are well suited for storing, archiving and
backing up large volumes of data in automated tape
libraries. These drives offer native capacities up to
160 gigabytes per cartridge and move data at rates as
fast as 16 megabytes per second, making them ideal for
mid-range UNIX and Windows NT environments. |

Applications |
Archiving
SDLT tape drives are a practical choice for
archiving growing volumes of business data. The
higher capacity and transfer rates of SDLT tape
drives increase archiving performance over
previous-generation tape drives. |
Disaster
recovery
SDLT tape drives are an integral part of disaster
recovery processes that remotely vault data in tape
form for recovery in case of disaster. Tapes can be
physically transported to a remote site, created
electronically with SDLT tape drives in a library at
the remote location, or created simultaneously at
both locations. |
Backup
and restore
Using SDLT tape drives for backup and restore
increases performance over previous-generation tape
drives, shortening backup and recovery times. SDLT
tape drives can be used in combination with other
drives to match specific backup and restore
performance and capacity needs. |

|
Benefits |
Investment protection
Our SDLT tape drives help you extend the value of
your storage investments via optional backward-read
compatibility with DLT 4000, DLT 7000 and DLT 8000
drives using DLTtapeIV cartridge media. |
Enhanced
data protection
StorageTek’s SDLT drives have a mean time between
failure (MTBF) rating of 250,000 hours at 100
percent duty cycle. This high level of reliability
gives you more confidence in your data protection
solution. |
Faster
backup/restore
The SLDT 320 tape drive delivers a sustained native
data transfer rate of 16 megabytes per second,
nearly 50 percent faster than earlier-generation
SLDT 220 drives. This helps you meet shrinking
backup/restore windows. |
Cost-effective capacity
With capacities up to 160 gigabytes per cartridge,
the SLDT 320 tape drive enables you to store more
data with fewer storage resources and at a lower
cost. |
|
| |
|
Features |
Industry-standard technology
These drives use Quantum’s SDLT tape technology, an
industry standard for storage. This provides
assurances that future generations of SDLT
technology will scale with your tape drive and
automation investments. |
Read/write compatibility
The SLDT 320 tape drive provides backward read/write
compatibility with SDLT 220 tape drives. It is
optionally backward-read compatible with multiple
DLT technologies using DLTtape IV cartridges. |
Interface
compatibility
The SDLT tape drive is available with either the HVD
or the LVD SCSI interface. This allows you to back
up and archive data on mid-range servers and
high-end workstations. |
