The StorageTek®
capacity-centric T9940 tape drive is ideal for
applications that demand high throughput and capacity.
The StorageTek T9940B tape drive stores up to 200
gigabytes of native data on a single tape cartridge at
rates as high as 30 megabytes per second. |

Applications |
Backup
and restore
Using T9940 tape drives for backup and restore
shortens backup and recovery times with high
transfer rates and fewer cartridge mounts and
dismounts. The T9940 drive can be used in
combination with other drives, including the T9840
fast-access tape drive, to match specific backup and
restore performance and capacity needs. |
Archiving
T9940 tape drives are a high-capacity choice for
enterprise archiving systems requiring continuous
use. When implemented with VolSafe®
write-once-read-many (WORM) secure media, T9940 tape
drives help secure critical data as it is archived.
|
Disaster
recovery
T9940 tape drives are an integral part of enterprise
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 T9940 tape drives in a
library at the remote location, or created
simultaneously at both locations. |
|
| |
|
Benefits |
Lower
backup costs
The T9940B drive’s low dollar-per-gigabyte media
helps you cut your total costs of backup. With data
compression, it can store as much as 400-800
gigabytes on a single cartridge. |
Lower
storage costs
T9940 tape drives do the work of multiple typical
mid-range drives. This enables you to minimize extra
hardware, reduce SAN complexity and simplify
management, to help reduce your costs. |
Increased
productivity
The high capacity T9940 tape drives minimize
cartridge mounts, require fewer cartridges to manage
for disaster recovery and improve automation
efficiency. |
Reduced
backup windows
With its native data transfer rate of 30 megabytes
per second, or up to 70 megabytes per second with
compression, the T9940B drive helps you store more
data in less time to meet your shrinking backup
windows. |
|
| |
|
Features |
SAN-readiness
A native two-gigabit fabric-aware Fibre Channel
interface makes the T9940B drive ready for the
demands of high-speed SAN environments and storage
server networks. |
Multi-platform connectivity
T9940 drives run on today’s popular operating
environments. The T9940B supports two gigabit Fibre
Channel connectivity. The T9940A drive supports
ESCON, SCSI and one gigabit Fibre Channel
connectivity. |
StorageTek VolSafe media support
The T9940B drive supports VolSafe® cartridges, a
high-capacity write-once-read-many (WORM) storage
solution. VolSafe is a non-erasable, non-rewritable
tape media for archiving critical data. |
Tape
compatibility
The T9940B drive provides backward read
compatibility with 9940A cartridges. It can rewrite
StorageTek 9940A tape cartridges with three times
more data, for extended investment protection. |
