Alfresco with ParaScale Cloud Storage
ParaScale offers on-premises, petabyte-level cloud storage that's easy to configure and expand as your content storage needs grow.
A free 4TB evaluation version of the ParaScale software is available from http://parascale.com
Alfresco can make use of the storage arrays my merely configuring Alfresco to use the mounted ParaScale volume as its Content Store location.
To do this, simply mount the ParaScale storage array. Let's assume that ParaScale has been mounted on /vol/NFS
On the Alfresco server, edit custom-repository.properties and add the following if not already present:
dir.root=/opt/alfresco/alf_data dir.contentstore=/vol/NFS/alfresco/alf_data/contentstore dir.contentstore.deleted=/vol/NFS/alfresco/alf_data/contentstore.deleted
Note that dir.root points to the local drive and NOT the ParaScale storage array. This allows Lucene indexes to be created on local storage which improves performance and diminishes the risk of corruption.
