WAN deployment

In a WAN deployment, the FlexCache volume is remote from the data center. As clients request data, the FlexCache volume caches popular data, giving the end user faster access to information.

The FlexCache volume is placed as close as possible to the remote office. Client requests are then explicitly directed to the FlexCache volume. If valid data exists in the cache, that data is served directly to the client. If the data does not exist in the cache, it is retrieved across the WAN from the origin system, cached in the FlexCache volume, and returned to the client. A WAN deployment is shown in the following diagram.
