DST 714

Quad Density

Scalable Automated Cartridge Library System

The DST714 quad density automated cartridge library system is a scalable system designed with the performance and flexibility needed to meet the growing requirements for fast-access mass storage.

Applications include online storage, sequential tape processing, backup, and archiving in computing environments spanning everything from digital television to scientific simulations, data warehousing and commercial data processing.

DST 714 Library

• Up to 11.6 terabyte capacity in only 7.5 square feet of floor space

• One or two DST drives, each with

independent Ultra-SCSI data paths

• Aggregate sustained data rate up to

40MB/second

• Robotic performance of 400 cartridge

exchanges per hour

• 20 seconds average access time to any file

• Fully automated archive, backup and

recovery

• Read compatible with ER90 “D2C”

cartridges and with single and double density DST/DIS cartridges

Library Extension Units

• Short transfer rail expands system up

to 34.4TB

• Long transfer rail expands system up

to 46.4TB

• Multiple cluster configurations create

almost unlimited storage capacity

The performance of the DST 714 quad density library is unrivaled by any other library system on the market. The fast robotics mount operation of 10 seconds, combined with a search rate of 2700MB/second, provides a total average access time for any file within the library in less than 20 seconds. The data transfer rate is up to 20MB/second per drive, with one or two high-performance DST drives per system. Each drive has its own Ultra-SCSI data path, producing an aggregate transfer rate of up to 40MB/second for the library. The cartridge design eliminates the need for a gripping mechanism, allowing the robotics to achieve unmatched performance and reliability.

A stand-alone DST 714 library can hold 116 100GB DST tape cartridges, putting a total storage capacity of up to 11.6 terabytes per library online in only 7.5 square feet of floor space. By using the cartridge partitioning feature in the DD-2 tape format, the library storage capacity can appear as over 41,600 200MB logical volumes to the host server. The 100GB tape capacity also serves to increase the system’s productivity.

The system’s scalability provides over 46TB utilizing a single transfer rail with four DST 714 cabinets. By stringing together multiple clusters almost unlimited capacity can be achieved. Additional drives can be added to dramatically increase I/O capability.

Ampex works with leading software companies to provide backup and recovery, archiving and HSM applications for the DST 714 library.
