Each machine hosting an image cache in the cluster is listed as a storage point in the Configure area - Stations section. (If you have multiple Curators, only the master Curator is listed as a storage point.) You can combine multiple image storage points into a single storage group. For example, if you have three storage points—CACHE1, CACHE2, and CACHE3—you can combine all of them into one storage group called Radimage. Then, you can have access to the image caches in that storage group flow through a load balancer, for example.
 | Tip: Only one set of storage groups is used for all station containers. You can define the storage groups in one station container, and all other station containers use the same set. However, you can configure different URLs to access the storage groups in each station container. |
Therefore, by organizing the stations that are running IMPAX into station containers, you can configure sets of stations to access different image caches. Each station container can be configured with an AE title that is used when determining priorities.
To prioritize the server accessed by the IMPAX Client workstation
From the Configure drawer menu
, select Stations.To group the remote workstations, under workstations, create a new station container.
If you want your station container names to be grouped together and to match the name to the virtual AE title (that will have a prefix of CS_ and a maximum of 16 characters) created in step 10, we recommend defining a station container name that has no more than 13 characters and does not contain spaces.
Add the remote stations to the station container.
You must know what stations (in the Internet container by default) belong to the remote facility.
In the navigation pane, select a station container.
In the details pane, expand the General bar.
Switch to the Image Access tab.
So that clients can access all servers, create storage group names for all the storage points.
Create ASPFTP URLs to access the storage directly.
The storage points (local and remote) are auto-populated. You must enter a fully qualified name to avoid resolution issues for the access URL.
Select the Use Station Container AET as Destination (AET) for Cache Priority in Image Access Manager checkbox.
In the AE Title field, add the AE title.
Note the following about the AE title:
The AE title is the virtual AE title of the station container that is created on the server side (in the map_ae table).
For consistency with the Image Access Manager in the IMPAX Administration Tools, the AE title should match the station container.
We recommend keeping the default prefix of CS_ (short for Client Station) to group all of the client stations containers together in the Image Access Manager.
More than 16 characters can be entered in this field, but only the first 16 characters are used. Ensure that the name the unique.
If you remove the station container, the map_ae reference is not removed. Use mvf-remove-ae to remove the virtual AE title from the server if required.
In the IMPAX Administration Tools, modify the image distribution responsibilities for a source station. Refer to “Modifying the priorities of station containers configured to optimize cache retrieval speed” (topic number 55242) in the IMPAX 6.5.1 Server Knowledge Base
 | Note: The same IMPAX Client configuration must be repeated for each remote and central facility, including the Internet (default) station container, which is usually left at the default HTTPS/PixelDataService access. This is required so that in every instance (even for the Application Server when it provides images using the default PixelDataService) image access is appropriately prioritized. |
