@ -69,6 +69,21 @@ provider networks to the storage bridge::
NeutronBridgeMappings: datacentre:br-ex,storage:br-storage
NeutronFlatNetworks: datacentre,storage
If the storage network uses VLAN, include storage network in
``NeutronNetworkVLANRanges`` parameter. For example::
NeutronNetworkVLANRanges: 'datacentre:100:1000,storage:30:30'
.. warning::
If network isolation is used, make sure that storage provider network
subnet doesn't overlap with IP allocation pool used for Overcloud storage
nodes (controlled by ``StorageAllocationPools`` heat parameter).
``StorageAllocationPools`` is by default set to
``[{'start': '172.16.1.4', 'end': '172.16.1.250'}]``. It may be neccessary
to shrink this pool, for example::
StorageAllocationPools: [{'start': '172.16.1.4', 'end': '172.16.1.99'}]
When Overcloud is deployed, create a provider network which can be used to
access storage network.
