What is Scalar i500?

Created for midrange storage environments, Scalar i500 tape libraries feature integrated iLayer software to dramatically improve the management, proactive monitoring, and security of your growing organization's backup process. With advanced diagnostic services, library resource management, and I/O management inside the library, iLayer monitors itself, so you don't have to worry about failed backups or restores. The Extended Data Life Management feature ensures your archived media is trouble-free so the data is available when you need it. Plus, Scalar i500 tape libraries are simple to install, operate, and maintain and can accommodate continual data growth, expanding to up to 6.1 PB of capacity.

Integrated management software makes the i500 easier to manage, reducing administrative time up to 75%.

Exclusive iLayer feature ensures availability of data placed in long-term storage/archive/DR.

Media, drive and security reports improve understanding of library utilization and performance. Automated report scheduling and distribution save time.

Improves service levels by reducing service calls 50% and resolution time by 30%.
