The Commvault backup appliances are flexible to meet your specific needs:

• Available in two licensing options – integrated back-end terabytes (BET) aligned to the usable storage capacity of the storage array, or sold as a hardware only option for use with traditional capacity-based licensing.
• Enables you to scale beyond backup to include optional snapshot management, email archiving, and/or search and eDiscovery.
• Supports the ability to combine multiple appliances for not only greater scale and load balancing, but also greater software resiliency to complement the hardware availability.
• Because every environment is unique.
