ProjectWise storage areas can exist on the ProjectWise Integration Server, but they can also be hosted on another server. ProjectWise Caching Server is the server to install when you want to set up and host a storage area on a server other than the ProjectWise Integration Server.

ProjectWise Caching Server can also be used for storing (caching) local copies of files whose master copies are in remote storage areas, to improve the speed that users are able to access to their documents.

When users create work areas and folders in ProjectWise, they associate each work area and folder with a particular storage area so that all files added to that work area or folder will be stored in the associated storage area. This storage area, defined in ProjectWise Administrator, can be located on the ProjectWise Integration Server computer, but for performance reasons you may decide to create multiple storage areas for your datasource, each located on a different server. Before you can define the location of a storage area in ProjectWise Administrator, you must first install ProjectWise Caching Server on the server that will host the storage area.

Once ProjectWise Caching Server is installed, you can use ProjectWise Administrator to set up a storage area on the ProjectWise Caching Server. The ProjectWise Administrator you work from can be, but does not need to be, installed on the same computer as ProjectWise Caching Server.
