Each time devices request resources that are not available on the Satellite Server's local cache, the data is retrieved from the HPCA Core server. If the Proxy Server dynamic caching is enabled on the Satellite server, the requested data is stored in the cache of the Satellite server, and provided to the client devices.
A Satellite server’s service cache can be preloaded with the data required by managed devices. A Satellite server automatically caches data when it is requested by a client device. Using the Synchronize feature, you can preload a Satellite server’s cache with all available data on the upstream server.
You can select which data to preload using the Cache tab in the Server Details window (after the Satellite server has been deployed).
Note: Preloading consists of downloading large binary files and therefore may affect overall network performance. When possible, perform synchronizations during off-hours when optimal network performance is not a priority.
To view the current synchronization status of each server, see the Last Synchronized column on the Satellite Servers list, or see the Synchronization section on the Cache tab in the Server Details window. Last Synchronized area records the last time the synchronize feature was initiated on a server.
Note: After a Satellite Server is first synchronized, a new entry is added to the Managed Devices report with an HPCA Agent ID of RPS_<DEVICENAME>. This entry exists specifically to display the preload status of the Satellite Server services and does not contain detailed hardware information for the associated device.
