Full Remote Tape & Data Management
 
All RLS tape libraries contain Q-Link Remote Library Manager, and our XLS series contain our X-Link Remote Library Manager. These web browser based remote library managers enable administrators to configure, upgrade, and monitor any of our libraries via a company intranet or over the Internet from anywhere in the world. Q-Link and X-Link extend the library’s comprehensive front panel menu system and adds additional functionality such as automatic e-mail notification based on rules set by the administrator, and remotely implemented firmware updates.
 
Eco-friendly Solutions
 
Storing data in a Qualstar tape library uses much less power than disk, saving money by substantially reducing both electrical and cooling requirements. See the Green vs. Green white paper for more information.
