The
system
Storwize® V3700
allows you
to change the array MDisks and storage pools that store a volume's data.
During data migration, host applications can continue to access
and use volume data as if no
data migration were occurring.
Data migration applications
Data migration has the following characteristics and applications:
- Data migration changes the MDisks that store data for one or more volumes.
- Data migration does not disrupt access to the volume data.
- Data migration can be used to move volume data from existing storage systems onto storage pools when you are adding Storwize V3700
to an existing SAN infrastructure.
- Data migration can be used when you are removing drives and array MDisks from the system.
- Data migration can be used to move volume data to a storage pool that has appropriate
performance for host requirements.
