Storage Center Operation Modes
Storage Center operates in four modes: Installation, Pre-production, Normal, 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 Normal mode.
Normal Normal 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 Proles
Storage Proles control how Storage Center manages volume data. For a given volume, the selected Storage Prole dictates which
disk tier accepts initial writes, as well as how data progression moves data between tiers to balance performance and cost.
Predened Storage Proles are the most eective way to manage data in
Storage Center. The Storage Proles available are
determined by the Storage Type.
The ability to select Storage Proles is controlled by user settings. Storage Proles may not be visible to all users. If your user volume
defaults allow you to select a Storage Prole, the Storage tab displays them under the Storage Proles node.
Storage Proles for Standard Storage Types
The table below summarizes the Storage Proles available for Standard storage types. Each prole 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 proles are not available for the Flash Optimized Storage
Type.
Recommended (All Tiers)
The Recommended Storage Prole is available only when Data Progression is licensed. Cost and performance are optimized when all
volumes use the Recommended Storage Prole. The Recommended prole allows automatic Data Progression between and across
all storage tiers based on data type and usage.
When a volume uses the Recommended Prole, all new data is written to Tier 1 RAID level 10 storage. Data Progression moves less
active data to Tier 1 RAID5/ RAID 6 or a slower tier based on how frequently the data is accessed. In this way, the most active
