Preventing Low Space Modes
Manage disk space to prevent a Storage Center from entering Conservation or Emergency mode.
Prevent low space issues using these tips:
• Empty the recycle bin regularly.
• Lower the frequency of snapshots or set snapshots to expire earlier.
• Change the storage prole to a more space-ecient prole. Available proles might include Low Priority (Tier 3) and Maximize
Eciency.
• Congure a threshold denition to create an alert when space starts to get low.
• Migrate volumes from a pagepool with a full tier to a dierent pagepool with more free space.
• Delete unnecessary volumes.
• If Data Reduction is licensed, enable Compression or Deduplication with Compression on some volumes.

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 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 might 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.
