Compress files for multisite transfer
You can compress File Management System (FMS) files before transferring them between FMS server caches (FSCs), increasing performance and reducing network traffic. File compression is available for FSC to FSC transfers across groups and across sites. File compression is controlled with two fscdefault elements (FSC_DoNotCompressExtensions and FSC_WANThreshold) and the compression attribute, available in the defaultfsc and linkparameters elements. To configure file compression for multisite transfer: Procedure Specify the file extensions you do not want compressed by adding the extension names to the FSC_DoNotCompressExtensions element, located within the fscdefault element in the fmsmaster_fscid.xml file. Enter values as a comma-separated list. FSCs do not send these file types as compressed files, nor request compressed content for these file types. The default value for this element is: <property-name="FSC_DoNotCompressExtensions" value="bz,bz2,cab,deb,docm,docx,ear,gif,gz,jar,jpeg,jpg,jt,lha,lzh,lzo,mp3, mp4,mpg,rar,rpm,sit,taz,tgz,war,xlsm,xlsx,z,zip" overridable="true"/> Specify the minimum file size threshold that must be reached before files are compressed by setting the FSC_WANThreshold element located within the fscdefault element in the fmsmaster_fscid.xml file. Files smaller than this value are not compressed. This value also determines the threshold file size that must be reached before WAN acceleration is used. The default setting is 256K. This value also determines the threshold file size that must be reached before WAN acceleration is used. The default setting is 32K. For multisite transfer, add the compression attribute to the defaultfsc element and set it to gzip. For example: Copy
