Qualstar TLS6000 SDLT Tape Library

TLS-6000 Tape Library System for SuperDLT Drives
Tape Libraries for Backup, Archive and Storage Management


TLS-6000 Tape Library System
for SDLT Drives:

  • SANSmart Fibre Channel
  • Super DLTtape Technology
  • Product Description:
    Our TLS-6000 Series Automated Tape Libraries offer superior performance and value for SuperDLT tape users. With capacities from 6 terabytes to over 144 TB, the TLS-6000 Series economically and reliably automates SDLT-based applications, whether backing up a single server or as an integral part of an enterprise-wide storage management solution.The TLS-6000 family comprises five models, providing a broad range of cost-effective solutions. Housing one to eight SuperDLT 600 tape drives and up to 240 tapes, TLS-6000 multi-drive library models readily support concurrent reading and writing. Data transfer rates can exceed 2 terabytes per hour to meet the throughput needs of today’s rapidly-growing networks.The SANSmart Fibre Channel Option supports LAN-free and serverless backup using the latest SAN technologies.All TLS-Series libraries include Q-Link, Qualstar’s web browser accessed remote library manager that enables administrators to configure, upgrade, and monitor any TLS-Series tape library via a company intranet or over the internet from anywhere in the world. Q-Link extends the library’s comprehensive front panel menu system and adds additional functionality such as automatic e-mail notification based on rules set by the administrator, and firmware updates can be implemented remotely.The TLS-6000 Series also includes barcode scanning of tape cartridges, and an I/O Port for importing and exporting individual tapes under application control.

    Developed for the RLS-Series libraries, VIOP is now incorporated in every TLS model. An exclusive Qualstar design feature, VIOP, Variable I/O Port, allows users to match the number of I/O slots to their operational requirements. Applications are not constrained by limits imposed by libraries with a fixed number of I/O slots. Users can assign the number of slots to best match their requirements. VIOP compliments the hardware I/O Ports which continue to be included or available in all models.

    Logical Library is built into every SCSI TLS-Series library. It allows up to four servers to share a single library via a SCSI interface, even if each server is running a separate application. Systems that you couldn’t afford to upgrade can now be protected automatically. Support for multiple SCSI busses is also built-in to maximize throughput in direct-attach architectures.

    Qualstar is known worldwide for quality and reliability. All electrical and mechanical adjustments have been eliminated for easy installation and enhanced reliability. Tape drive reliability is improved by providing individual fans for each drive to insure proper cooling. Filtered, positive air pressure is maintained throughout the library to reduce contamination.

    Providing built-in capacity and performance growth is a hallmark of all Qualstar TLS-Series automation families. All drive bays are pre-wired: users can easily install additional tape drives for increased throughput. Field upgrade kits are also available to double the tape capacity of some models.

    Founded in 1984, Qualstar has been designing and manufacturing tape automation products since 1994. Offering over 30 models for AIT, SAIT, SDLT and LTO formats, our TLS-Series families consistently set industry standards for quality, performance and value.
