The Hazelcast library provides support for distributed data structures and communications channels that allow certain components of the SkyVault content repository server to function properly within a clustered environment. While configuring JLAN clustering, if you wish to cluster CIFS, FTP or NFS protocols with a SkyVault repository, you will need to configure the hazelcastConfig.xml file. This file is located at SkyVault/tomcat/shared/classes/alfresco/extension.
