Exit FSC cache configuration

This configuration illustrates a shared cache at a remote site with volumes. Users have shared local LAN access to recently accessed files from other FSC groups. FSC servers route outbound requests to an exit FSC, which routes the requests to FSCs outside the group. The exit FSC routes the requests either to the outside group’s entry FSC (if configured) or to an FSC that serves the requested resource. Outbound requests are requests for data on a resource outside the group. Outbound requests typically originate within the group, but this is not always the case. The exit FSC is primarily a cache server. Its purpose is to populate and serve data originating outside the group from its cache whenever possible. The data in its cache is high value. By serving the data from its cache, a WAN trip is prevented. Maintain the high value of the data in the exit FSC cache by setting the FSC_CachePolicy element to CacheIfNotInLocalFSCGroup. This prevents the exit FSC from caching group data. Primary configuration file (FSC_HOME/fmsmaster_fscid.xml) This file is configured similar to the example for the FSC cached configuration. See the FSC_HOME/fmsmaster.xml.template file for all available elements. Key points of this file in this configuration are: ExitFSC element This configuration includes an exit FSC that caches data from outside groups. It also includes a second FSC remote group that contains local volumes. FCC_EnableDirectFSCRouting element The FCC_EnableDirectFSCRouting element is set to true. FCCs in each FSC group route requests for locally served volumes directly to the FSCs serving the volume. Therefore, local requests from rich clients are not routed through the AssignedFSC or ExitFSC elements. AssignedFSC element The AssignedFSC element for each group is ExitFSC. Therefore rich clients route requests for data served outside the group to the exit FSC first. FSC_Cache Policy element The FSC_CachePolicy element is set to CacheIfNotInLocalFSCGroup in FSCGroup1 and FSCGroup2, preventing the FSC caches within the groups from storing data served within the local FSC group. Link parameters WAN acceleration is enabled from the remote office to the central office using the linkparameters fromgroup element. An example of the primary configuration file for this configuration is: Copy FSC configuration files (FSC_HOME/fsc.xml) See the FSC_HOME/fsc.xml.template file for all available elements. This FSC configuration file for this configuration has the same key points as the FSC cached configuration.
