Storage Profiles
Overview
Storage Profiles describe the RAID level and tiers on which data is stored. If disk space is
not available within a selected tier, space in other tiers is used until space becomes
available in the selected tier. All Storage Centers provide a set of standard Storage Profiles.
• If Data Progression is licensed, data can be migrated between RAID levels within a
tier and between tiers. The system displays the Recommended Storage Profile to
migrate data between tiers. The default Storage Profile for a system with Data
Progression is the Recommended Storage Profile
• If Data Progression is not licensed and a system uses RAID 10 and RAID 5, data is
migrated up or down with in a Tier (drive class) but cannot be migrated between Tiers.
If Data Progression is not licensed, a system has access only to Storage Profiles that
use a single tier of storage; Storage Profiles with multiple tiers are not available. The
default Storage Profile for a system without Data Progression is the High Priority
Storage Profile.
The Volume General Tab displays the Storage Profile attached to a volume.
