Qualstar RLS Rack Serie Overview
The RLS-Series delivers Qualstar's Simply Reliable Automated Tape Library technology to users requiring rackmountable solutions.
The RLS-Series supports LTO and AIT cartridge tape formats, giving users technology choices without compromising quality or reliability, in compact 5U-high modules. Offering superior performance and value, the RLS-Series Tape Library family includes eight models yielding capacities over 35 terabytes (native). Using typical data compression ratios, capacity can exceed 72 terabytes.
Depending on the drive technology chosen, individual models house up to four drives. Data transfer rates can exceed 3.5 terabytes per hour. Each drive is on a self-connecting mount that eliminates handling slide the drives in or out.
High Availability plus Q-Link
RLS High Availability options include hot-swappable redundant power supplies, true hot-swappable
drives, and Q-Link, the web browser based remote library manager. Q-Link allows any
RLS-Series library to be configured, monitored, diagnosed and managed from anywhere in the
world. Using Q-Link, companies can deploy enterprise-class data protection without increasing
staffs or degrading data security. Even firmware updates can be implemented remotely.
Flexible Connectivity
The Fibre Channel Interface Option supports the latest SAN technology. The iSCSI option connects
RLS Libraries to IP SANS.
Capacity on Demand
The RLS-8204 offers an unbeatable combination of low cost and easy capacity upgrades as
needed. Starting with twelve data slots, up to four, 8-slot expansion modules can be installed.
A simple software key and a pair of magazines is all it takes to add capacity.
DFA Drives Supported
RLS-8236D and RLS-8244D models house LTO 3 or LTO 4 Direct Fibre Attach tape drives. These
drives connect directly to ports on switches or to servers. The RLS library control interface can be
connected with SCSI, or with Fibre Channel using the FCO option.
Half-High Drives Supported
The RLS-8444H model can house up to four LTO 3 or LTO 4 SCSI LVD half-high tape drives,
doubling the number of target devices capable of simultaneous operation. Data transfer rates can
exceed 3.5 terabytes per hour using LTO 4 half-high drives.
Investment Protection
Featuring IPM (Interface Personality Module) Architecture, RLS-Series libraries can be reconfigured
in seconds for SCSI or Fibre Channel by simply plugging in the appropriate IPM. A field capacity
expansion kit is also available to economically upgrade the RLS-4445 to an RLS-4470.
Reliable, Intelligent Robotics
The RLS-Series unique robotic mechanism is Simply Reliable by design. Leadscrew-based robotics
using brushless DC motors and closed-loop servo control systems provide precise positioning and
flawless media handling for years of dependable operation. All FRUs, options and tape drives are
auto-discovering, and all electrical and mechanical adjustments have been completely eliminated by
sophisticated, adaptive 'smart' logic design.
Easy Operation
An intuitive menu-driven control system provides easy-to-use installation, configuration, and
operational information via the onboard LCD panel. Critical operating functions are displayed and an
audible alarm signals conditions requiring immediate action. All of the information, functions and
controls built into the front panel display are replicated in Q-Link, the powerful, browser-based remote
library manager. Tapes are housed in convenient magazines that simply snap in and out of the library.
Removing and organizing tapes for off-site storage has never been easier.
Advanced Cartridge Management and Security
Bar code scanning enhances throughput and controls the media inventory. VIOP, a unique variable
I/O port design, allows users to determine how many slots to commit to importing and exporting tapes.
Our exclusive 'Inventory Sentry' senses whether the tapes or magazines have actually been
removed when the door is opened. If they haven't, operation is resumed without causing a time
consuming re-inventory.
Logical Library
Logical Library partioning is built into every RLS-Series SCSI library. It allows up to four servers to
share a single library, even if each server is running a separate application. Systems that you couldn't
afford to upgrade can now be protected automatically
