A customer is looking to replace or augment their Sun Thumper with a ZFS appliance like 7320. However, the Thumper was used not only as a protocol storage server (home dirs, files, backups over NFS/CIFS/Rsync), but also as a general-purpose server with unpredictably-big-data programs running directly on it (such as corporate databases, Alfresco for intellectual document storage, etc.) in order to
