## Response Elements
<a name="API_DescribeStorageConfiguration_ResponseElements"></a>

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [configurationStatus](#API_DescribeStorageConfiguration_ResponseSyntax) **   <a name="iotsitewise-DescribeStorageConfiguration-response-configurationStatus"></a>
Contains current status information for the configuration.  
Type: [ConfigurationStatus](API_ConfigurationStatus.md) object

 ** [disallowIngestNullNaN](#API_DescribeStorageConfiguration_ResponseSyntax) **   <a name="iotsitewise-DescribeStorageConfiguration-response-disallowIngestNullNaN"></a>
Describes the configuration for ingesting NULL and NaN data. By default the feature is allowed. The feature is disallowed if the value is `true`.  
Type: Boolean

 ** [disassociatedDataStorage](#API_DescribeStorageConfiguration_ResponseSyntax) **   <a name="iotsitewise-DescribeStorageConfiguration-response-disassociatedDataStorage"></a>
Contains the storage configuration for time series (data streams) that aren't associated with asset properties. The `disassociatedDataStorage` can be one of the following values:  
+  `ENABLED` – Amazon IoT SiteWise accepts time series that aren't associated with asset properties.
**Important**  
After the `disassociatedDataStorage` is enabled, you can't disable it.
+  `DISABLED` – Amazon IoT SiteWise doesn't accept time series (data streams) that aren't associated with asset properties.
For more information, see [Data streams](https://docs.amazonaws.cn/iot-sitewise/latest/userguide/data-streams.html) in the * Amazon IoT SiteWise User Guide*.  
Type: String  
Valid Values: `ENABLED | DISABLED` 

 ** [lastUpdateDate](#API_DescribeStorageConfiguration_ResponseSyntax) **   <a name="iotsitewise-DescribeStorageConfiguration-response-lastUpdateDate"></a>
The date the storage configuration was last updated, in Unix epoch time.  
Type: Timestamp

 ** [multiLayerStorage](#API_DescribeStorageConfiguration_ResponseSyntax) **   <a name="iotsitewise-DescribeStorageConfiguration-response-multiLayerStorage"></a>
Contains information about the storage destination.  
Type: [MultiLayerStorage](API_MultiLayerStorage.md) object

 ** [retentionPeriod](#API_DescribeStorageConfiguration_ResponseSyntax) **   <a name="iotsitewise-DescribeStorageConfiguration-response-retentionPeriod"></a>
