XLS-832700 LIBRARY RESOURCE MODULE

XLS 832700 - transp

XLS is Qualstar’s Simply Reliable highly modular enterprise library system. It delivers new levels of density, flexibility, scalability and ease of use, coupled with our proven record of reliability and value. If your need is for large tape storage capacity with very high throughput capability, the XLS‑832700 is the right choice of Library Resource Module (LRM) for you. In a multi-unit configuration with XLS‑89000 Media Expansion Modules, library capacity can be expanded to more than 6,300 tapes – see XLS Configurations.

Key Highlights

  • Single LRM scales easily from 4 to 32 LTO 5 or LTO 6 tape drives, with maximum throughput capacity exceeding 18 PB per hour
  • Options allow a single LRM to be configured with a capacity from 235 tape slots up to a maximum of 695 slots
  • Patented Compass Architecture enables full 360 degree robotic tape access, minimizing robot seek times
  • Up to 40 I/O slots per LRM speed bulk tape handling operations
  • Up to eight independent host connections, each with its own logical partition
  • Integrated diagnostics and advanced monitoring maximize uptime
  • Advanced single-view, browser-based interface provides uniform local and worldwide management
  • Large color touch-screen facilitates local management and control of the library
  • N+1 power system and hot-swappable components
  • Highly efficient robotics design yields low power consumption, reduced cooling requirements
  • Qualstar Technical Support provides remote diagnostic access to minimize service interruptions and reduce downtime
  • Extended Service and Support plans are available

XLS-8161100 LIBRARY RESOURCE MODULE

XLS is Qualstar’s Simply Reliable highly modular enterprise library system. It delivers new levels of density, flexibility, scalability and ease of use, coupled with our proven record of reliability and value. XLS‑8161100 is the higher capacity member of the XLS family, and can be expanded in a multi-unit configuration to hold about 7,500 tapes – see XLS Configurations.

XLS-890000 MEDIA EXPANSION MODULE

Used in conjunction with either type of XLS Library Resource Module, the XLS-89000 MEM unit provides the ability to build large XLS library systems. When an LRM unit and a MEM unit are attached side-by-side, the patented Compass Architecture of the LRM’s robotic tape handler enables it to directly access tapes in the carousel storage slots of the MEM unit. Alternating LRM and MEM units may be ‚daisy chained‘ to achieve a tape capacity of as many as 7,500 cartridges.

Key Highlights

  • Single MEM unit has capacity for up to 1,075 tape cartridges
  • Patented carousel technology enables very high density – 316 TB (uncompressed data) per square foot
  • Field expandable to a maximum of 3 LRM and 4 MEM units for increased library capacity
  • Works with either XLS-832700 or XLS-8161100 LRM unit
XLS SYSTEMS COMPRISING MULTIPLE LRM AND MEM UNITS

XLS Configurations

The two types of Library Resource Modules, XLS‑832700 and XLS‑8161100, may be used as stand-alone libraries or they may be used in conjunction with XLS‑89000 Media Expansion Modules to build very high capacity libraries.

Qualstar’s patented Compass Architecture allows the robotic tape handler in each LRM to rotate through a full 360 degrees, enabling it to access tapes from the slots of one or two MEM units attached to the sides of the LRM, as well as from the LRM’s own internal slots. This combination of Compass Architecture and Qualstar’s patented high-speed carousel technology offers several advantages:

  • High reliability resulting from the use of separate robots in each LRM, each of which never has to travel more than 21″ laterally.
  • Easy library expansion, as no change is required to the tracks on which the tape handler robots travel. (Note: Some competitive systems require track replacement during library expansion, to enable a single robot to traverse across multiple cabinets.)
  • Very fast tape seek times, because carousel rotation and robot positioning take place concurrently.
