File System

Cloud Tier storage is optional, and you can configure it later. The file system must be disabled to
configure Cloud Tier storage.

Configure storage tier pages
The configure storage tier pages enable you to configure storage for each licensed tier on the
system, Active Tier, Cache Tier, and Cloud Tier. Each tier has a separate wizard page. The storage
tier configuration pages cannot be accessed through the wizard if the file system is already
created.
