In addition , to cope with the huge , terabyte-order data volume that comes with miniaturization , a SAN ( storage area network ) system was adopted to unify management of previously localized data and to expedite data management and conversion processing to reduce the burden on the system user . In conventional systems , data storage is distributed among individual servers , but storage networking technology such as the SAN ( storage area network ) and storage virtualization technology enable storage to be virtually consolidated on multiple storage devices in a storage network ( virtual consolidation of devices ) . The integrated X4500 solution will be a good fit at sites where deploying a SAN ( storage area network ) or NAS ( network-attached storage ) is n't feasible due to budgeting or physical space constraints or when higher data access throughput is desired .
