T9840 tape drives
 
The StorageTek® access-centric T9840 tape drive is ideal for applications that demand high data throughput and fast recall. Available with two-gigabit Fibre Channel and two gigabit FICON connectivity, these drives give you access to data at an average of just 12 seconds. The StorageTek T9840C drive stores up to 40 gigabytes native on a single cartridge.

Applications
Fixed content distribution
Tape libraries can act as a high-volume source for fixed content data when outfitted with fast-access T9840 tape drives. When implemented with VolSafe write-once-read-many (WORM) secure media, T9840 tape drives help secure high-value fixed content while it is distributed.
Offline processing
Fast-access T9840 tape drives provide a cost-efficient option to disk for offline processing applications.
Backup and restore
Using T9840 tape drives for backup and restore shortens backup and recovery times and improves system response time. The T9840 can be used in combination with other drives, including the T9940 tape drive, to match specific backup and restore performance and capacity needs.
 
Benefits
Higher resource utilization
The T9840C drive stores up to 40 gigabytes per cartridge, twice the capacity of StorageTek T9840A and T9840B tape drives. This effectively doubles the capacity of existing cartridges and libraries.
Increased productivity
Higher data transfer rates enable you to reduce batch windows and improve access to data, so your IT staff can get more work done in less time.
Reduced backup windows
With native data transfer rates as high as 30 megabytes per second, the T9840C drive allows you to store more data in less time to meet your shrinking backup windows.
Faster access to information
Faster data access enables you to meet more of your data storage needs with affordable tape, minimizing the need for higher-cost disk.
 
Features
Standard features:
SAN-readiness
A native two-gigabit fabric-aware Fibre Channel interface makes the T9940C drive ready for the demands of high-speed SAN environments and storage server networks.
FICON for distance
The T9840B FICON drive supports distances up to 100 kilometers (versus nine kilometers for ESCON) without channel extensions or significant throughput reduction. This enables remote storage applications and increases your disaster recovery options.
Connectivity choices
The T9840 products include two-gigabit Fibre Channel, one-gigabit Fibre Channel, two-gigabit FICON and Ultra-SCSI HVD interface options, enabling you to choose the right connectivity for your implementation.
StorageTek VolSafe media support
The T9840 drives support 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.
