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
