Go to the head of the class with the T9840C
Move data at a rate of 30 megabytes per second and improve response times, shrink backup windows, accelerate batch processing, cut recovery times and improve system and application availability.
Features and Benefits
The T9840C sets the standard for fast data access, fast recall and high throughput cost-effectively in data intensive, heavy duty cycle environments.
Key Benefits
- The T9840C’s fast access meets data storage needs affordably and minimizes the need for higher cost disk
- Mix and match tape drives in Sun StorageTek libraries and achieve the optimum balance of access and capacity
- Robust design delivers enterprise-class ultra-reliability and minimizes the risk of downtime
- Improves resource and space utilization with high data capacities on a single cartridge
Improve availability, reliability and accessibility
Increase reliability
Like all StorageTek enterprise-class T-series tape drives, the T9840C is designed exclusively for high-duty cycles in automation environments. It delivers exceptional reliability in even the harshest operating conditions.
Enhance data accessibility
The T9840’s industry-leading average data access time of 12 seconds provides quick access to their data when its’ needed. Meet service level requirements at a lower TCO.
Facilitate compliance with regulatory demands
The T9840 tape drive family supports Sun’s StorageTek VolSafe media cartridges, the industry’s premier non-erasable, non-rewriteable, tape-based write once read many (WORM) storage solution. Once information is written to tape, additional information can then be added or read as often as needed, but never changed, modified or deleted.
Simplify storage management and increase productivity
Make it simple, yet have choices
The T9840 family of drives reduces complexity by allowing data management for multiple platforms and applications from a central location. It provides interface flexibility with native Fibre Channel, ESCON and FICON connectivity options. And simultaneous vaulting at remote sites increases business continuity options.
Increase IT productivity
The T9840C boosts data transfer speeds across the enterprise, shortening batch times in mainframe environments and reducing backup windows in open systems environments. Protect more data in less time and still provide users with quick access to information.
Leverage existing IT infrastructures
Currently using StorageTek T9840 drives? Simply reformat existing cartridges to store higher capacities and apply your media budget to the purchase of other storage assets.

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. |
