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