StorageTek™
T9940B tape drive
 
The StorageTek T9940B designed to provide the ultimate
in data reliability during heavy-duty 7x24 use. The native capacity is 200 GB
capacity per cartridge (typically 400-600GB with compression), with 30 MB/s
native data transfer speed (70 MB/s with compression). The T9940B attaches to
numerous server platforms and networks with the industry’s first native 2 Gbit
Fibre Channel interface. T9940B provides the ultimate solution for
data-intensive applications such as backup, recovery, archiving and scientific
data acquisition and processing.
The T9940B is the most cost-effective solution for the rapid,
secure movement of highly valuable data. It provides a high-performance/high
capacity solution without compromising data integrity or product reliability
across all networks and systems.

Key Business Benefits
- Highest capacity triples existing StorageTek library
storage space without needing to add libraries or floor space
- Highest sustained data transfer rate performance
dramatically reduces back up times; does more work in less time
- Highest reliability protects data and reduces down time and
total cost of ownership
- Native 2 Gbit Fibre Channel interface directly attaches to
SANs and hosts without the cost of additional adapters
- Backward read compatible with T9940A
- Coexists in mixed media StorageTek libraries to increase
utilization and investment life of existing library resources.
Key Benefits
- Supports top-line business growth
by affordably and reliably storing greater amounts of critical
business data.
- Data can be simultaneously vaulted
to remote sites for recovery in case of disaster.
- Reduces total cost of ownership by
storing data on high-performance, capacity-centric tape instead of
higher-cost disk or less-efficient tape.

Reduce complexity and simplify SAN
management
Expand compatibility
The T9940B simplifies storage management and
integrates easily with existing mainframe and open systems platforms and
applications. It supports multi-platform connectivity, including native
FICON, ESCON and Fibre Channel.
Leverage existing IT infrastructure
The T9940B provides backward-read
compatibility with 9940A cartridges. It can rewrite the cartridges with
three times more data, for extended investment protection.
Facilitate compliance with regulatory demands
Integrate the T9940 with VolSafe media
cartridges and the result in a cost-effective, highly reliable archiving
solution that helps address the most stringent electronic storage regulatory
and legal requirements, including those of the U.S. Securities and Exchange
Commission.
Improve availability and reliability while
increasing productivity
Keep up and running
Like all Sun StorageTek enterprise-class
T-series tape drives, the T9940B is designed exclusively for high-duty
cycles in automation environments. It delivers exceptional reliability in
even the harshest operating conditions.
Increase productivity
The high-capacity T9940B tape drive minimizes
cartridge mounts, requires fewer cartridges to manage for disaster recovery
and improves automation efficiency. Store more data in less time to meet
shrinking batch and backup windows.

Notes

| Notes |
* The actions of the tape
drive can be divided into four distinct phases: Phase 1: Load time — the
amount of time required to insert a cartridge in the drive, load the tape
and prepare to read, write or search. Phase 2: Average file access time —
the amount of time required to search from the beginning of the tape to the
midpoint; does not include load time. Phase 3: Maximum rewind time — the
amount of time required to rewind the tape from the end to the beginning of
the tape. The average rewind time is the time to rewind a tape from the
midpoint to the beginning, i.e. one-half of the maximum rewind time. Phase
4: Unload time — the amount of time required to eject the cartridge from the
drive. |
