Storage Center Operation Modes
Storage Center operates in four modes: Installation, Pre-production, Production, and Maintenance.
Name Description
Install Storage Center is in Install mode before completing the setup wizard for the Storage Center.
Once setup is complete, Storage Center switches to Pre-Production mode.
Pre-Production During Pre-production mode, Storage Center suppresses alerts sent to support so that
support is not alerted to expected test scenarios caused by testing. Use the Pre-production
mode to perform tests on the Storage Center before placing it into a production environment.
After passing tests, manually change the operational mode from Pre-production to Production
mode.
Production Production mode is the operation mode used when the Storage Center is in a production
environment. Storage Center does not suppress alerts in this mode.
Maintenance When Storage Center is in Maintenance mode, it suppresses alerts sent to support in the
same way when it is in Pre-production mode. Switch to Maintenance mode before performing
maintenance on the Storage Center that may trigger alerts to support.

Storage Profiles
Storage profiles control how Storage Center manages volume data. For a given volume, the selected storage profile dictates
which disk tier accepts initial writes, as well as how data progression moves data between tiers to balance performance and
cost. Predefined storage profiles are the most effective way to manage data in Storage Center. The storage profiles available
are determined by the storage type.
The ability to select storage profiles is controlled by user settings. Storage profiles might not be visible to all users. If your user
volume defaults allow you to select a storage profile, the Storage tab displays them under the Storage Profiles node.
Storage Profiles for Standard Storage Types
The table below summarizes the storage profiles available for standard storage types. Each profile is described in more detail
following the table.
Name
Initial Write Tier Tier (T) and RAID Levels Progression
Recommended (All Tiers) 1 Writes: T1 RAID 10 Snapshots:
RAID 5/RAID 6
Yes - to all Tiers
High Priority (Tier 1) 1 Writes: T1 RAID 10 Snapshots:
T1 RAID 5/RAID 6
No
Medium Priority (Tier 2) 2 Writes: T2 RAID 10
Snapshots: T2 RAID 5/RAID 6
No
Low Priority (Tier 3) 3 Writes: T3 RAID 10
Snapshots: T3 RAID 5/RAID 6
No
NOTE: The Recommended, High Priority, and Medium Priority profiles are not available for the Flash Optimized storage
type.
Recommended (All Tiers)
The Recommended storage profile is available only when data progression is licensed. Cost and performance are optimized when
all volumes use the Recommended storage profile. The Recommended profile allows automatic data progression between and
across all storage tiers based on data type and usage.
