+# == define: cinder::backend::dellemc_unity
+#
+# Configure the Dell EMC Unity Driver for cinder.
+#
+# === Parameters
+#
+# [*san_ip*]
+#   (required) IP address of Unity Unisphere.
+#
+# [*san_login*]
+#   (required) Unity Unisphere user name.
+#
+# [*san_password*]
+#   (required) Unity Unisphere user password.
+#
+# [*storage_protocol*]
+#   (required) The Storage protocol, iSCSI or FC.
+#
+# [*volume_backend_name*]
+#   (optional) The storage backend name.
+#   Defaults to the $name of the backend
+#
+# [*unity_io_ports*]
+#   (optional) A comma-separated list of iSCSI or FC ports to be used.
+#   Each port can be Unix-style glob expressions. The Unity Unisphere API port.
+#   Defaults to $::os_service_default
+#
+# [*unity_storage_pool_names*]
+#   (optional) A comma-separated list of storage pool names to be used.
+#   Defaults to $::os_service_default
+#
+# [*extra_options*]
+#   (optional) Hash of extra options to pass to the backend stanza.
+#   Defaults to: {}
+#   Example:
+#     { 'dellemc_unity_backend/param1' => { 'value' => value1 } }
+#
+# [*manage_volume_type*]
+#   (Optional) Whether or not manage Cinder Volume type.
+#   If set to true, a Cinder Volume type will be created
+#   with volume_backend_name=$volume_backend_name key/value.
+#   Defaults to false.
