FSC cached configuration

This configuration provides a high-speed cache server for improved client performance. When users upload new files to the volume, the files are cached in the FSC cache but streamed to the volume. This results in two copies of the file, but should not affect performance. Downloaded files are also cached. Typically, the end result is that the FSC cache server holds a small percentage of the most commonly accessed files, and the number of file accesses to the volume servers is substantially reduced. A benefit of this configuration is that clients may continue to download commonly accessed files with brief outages of the volume server network by downloading files from the FSC cache. Primary configuration file (FSC_HOME/fmsmaster_fscid.xml) This file is configured similar to the example for the FCC direct connect configuration. See the FSC_HOME/fmsmaster.xml.template file for all available elements. Key points of this file in this configuration are: FSC cache This configuration contains an FSC cache. The FSC cache acts as both a cache server and a configuration server. It does not provide volume or transient volume server functions. FCC_EnableDirectFSCRouting element Set this configuration parameter to false to disable direct routing. This causes all FCC data access to be provided by the FCC's assigned FSC. If this parameter is not set, the client FSCs directly access the FSC volume servers. FSC cache sizing The FSC uses the default read/write partial cache configuration and sizes. A sample of the primary configuration file for this configuration is: Copy FSC configuration files (FSC_HOME/fsc.xml) This FSC configuration file is similar to the FSC direct connect configuration file. Each FSC has a separate fsc.xml file. See the FSC_HOME/fsc.xml.template file for all available elements. In this configuration, additional key points of the FSC configuration file are: Separation of configuration and data paths All clients and all FSCs bootstrap the configuration from csun16.ugs.com:4444. FSC cache This configuration includes an FSC cache. This configuration also requires an FSC configuration file. A sample of the FSC configuration file for this configuration is: Copy FSCCACHE FSC1 FSC2 FSC3 FCC configuration file (FMS_HOME/fcc.xml) This example of the FCC configuration file is similar to previous examples: Copy
