FAST VP accelerates performance of a specific storage pool by automatically moving data within that pool to the appropriate drive technology, based on data access patterns. FAST VP is only applicable to hybrid pools within a Dell Unity hybrid system.
The default and recommended FAST VP policy for all storage objects is “Start High then Auto-tier”. This policy places initial allocations for the storage object in the highest tier available, and monitors activity to this storage object to determine the correct placement of data as it ages.
FAST VP is most effective if data relocations occur during or immediately after normal daily processing. Dell Technologies recommends scheduling FAST VP relocations to occur before backups or nightly batch processing. For applications which are continuously active, consider configuring FAST VP relocations to run constantly.
Dell Technologies recommends maintaining at least 10% free capacity in storage pools, so that FAST VP relocations can occur efficiently. FAST VP relocations cannot occur if the storage pool has no free space.
