StorageTek™ T9940B tape drive

Front angle view - openT9940B

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.

Sun StorageTek™ T9940B Tape Drive

The StorageTek™ T9940B tape drive, described as capacity-centric, offers exceptional storage capacity for business and scientific applications such as high-volume data acquisition and recall, backup, archive, record retention, and disaster recovery. It delivers uncompromised value by affordably and reliably storing vast amounts of historical data for critical business applications.

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.
