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 EIA 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 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. |
