The XLS accommodates up to eight 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.


X-Link is a powerful, brow-fluidser-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.


Up to eight individual library partitions can be established. Each partition contains Fibre Channel 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.


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.


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.


N+1 power is standard on the XLS-832700 and XLS-8161100 and optional on other models. 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.
