Using FlexCache volumes to cache clustered Data ONTAP volumes

You can cache a clustered Data ONTAP volume outside the cluster by using a FlexCache volume in a storage system that is deployed at a remote site and connected to the cluster over a Wide Area Network (WAN). This type of configuration can help in situations such as distributing read-intensive data across multiple locations.

You must consider the following when using a FlexCache volume to cache a clustered Data ONTAP volume outside the cluster:

• The FlexCache volume must be connected directly to the clustered Data ONTAP volume and not to any namespace or junction point.
• The client applications cannot access volumes that are associated with the FlexCache volumes through junctions.

For more information about clustered Data ONTAP volumes, see the Clustered Data ONTAP Logical Storage Management Guide.
