===============================
|
|
|
|
As an administrative user, you have some control over which volume
|
|
back end your volumes reside on. You can specify affinity or
|
|
anti-affinity between two volumes. Affinity between volumes means
|
|
that they are stored on the same back end, whereas anti-affinity
|
|
means that they are stored on different back ends.
|
|
|
|
For information on how to set up multiple back ends for Cinder,
|
|
refer to :ref:`multi_backend`.
