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 16 LTO 5 or LTO 6 tape drives, with maximum throughput capacity exceeding 9 PB per hour
• Options allow a single LRM to be configured with a capacity from 724 tape slots up to a maximum of 1064 slots
• Patented Compass Architecture enables full 360 degree robotic tape access, minimizing robot seek times
• High-speed carousel technology enables high density – over 236 TB of data (or 590 TB compressed data) per square foot
• 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

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.
