FEATURES
N+1 hot swappable power system Up to 40 I/O slots per LRM Individual Fibre Channel or SCSI control interfaces for up to 8 partitions	Single-view, local and remote management Automatic fault notification 15” color touch screen for local control LED indicators provide real-time visual status information

FLEXIBILITY

The XLS accommodates up to eight intermixed SCSI or Fibre Channel library control channels. User configured parameters can be backed up remotely so that in the event of a major library controller failure/replacement the user configuration can be uploaded and the library brought back online immediately.

The XLS also offers optional 6U or 8U EIA¹ rack space to accommodate auxiliary equipment such as switches, RAID storage, storage controllers, or other equipment.

X-LINK™ SINGLE-VIEW WORLDWIDE INTERFACE

X-Link is a powerful, browser-based graphical user interface that gives both local and remote administrators a single-view, comprehensive tool set to configure, manage, monitor and control XLS via a single IP connection, worldwide. A large color touch screen provides local management and control.

LOGICAL LIBRARY PARTITIONS

Up to eight individual library partitions can be established. Each partition can contain either Fibre Channel or SCSI tape drives, and a dedicated library control interface. X-Link gives administrators complete information about and control of the storage elements assigned to each partition, making setup, administration and re-configuration easy.

DATA-GUARD™ ONBOARD UPS

XLS is the first library to deliver built-in power failure protection for the library robotics, independent of any external power protection scheme. If input power to the library fails, the Data-Guard UPS maintains system power long enough to protect any media located in the picker assembly from harm. It also carries out an orderly shutdown of the library controllers and processor to allow problem-free restarts when power returns. UPS protection is restored after 10 minutes of normal operation recharges the onboard battery.

EASE OF SERVICE

XLS uses a modern FRU design incorporating easily exchanged modules. The power supplies, cooling fans, and drives are all designed for easy replacement. MTTR for any service operation is <30 minutes. Remote access by Qualstar Technical Support speeds monitoring and diagnosis to eliminate service interruptions.

HIGH AVAILABILITY

N+1 power is standard on the XLS-832700 and XLS-8161100 and optional on the XLS-812300 and XLS-820500. The system controller uses a journaling file system for faster recovery from power loss / system resets. XLS uses a distributed control intelligence connected by a high reliability CAN bus. Advanced diagnostics and error recovery procedures are incorporated in the XLS firmware design.
