Hardware Sizing Guidelines for Distributed Storage

Updated

On this page

3 storage servers configured similarly form the base cluster. Configuration is based on raw capacity of servers (HDD’s). The current recommended data resilience method is erasure-coding (4+2) for backup workloads and RF3 for copy data management workloads. Following are supported configurations when Commvault software is used for data-protection:
