The DiskXtender Appliance Edition aggregation software provides a simple, cost-effective solution for managing the complexities of data storage seamlessly with Network Attached Storage (NAS) devices. Using automated policy-based data management, DX/AE turns a Snap Server or Guardian Server into a storage management appliance that consolidates and centralizes distributed network data into a virtual storage pool. For example, you can "pool" five Snap Server 4100/480GB servers for a 2TB solution. Data which is not accessed frequently can be automatically migrated off of critical front-line servers to Snap Servers oir Guardian Servers, freeing up overloaded servers for application use. When needed, users have immediate and transparent access to all of their critical stored data with no administrator intervention. As storage requirements increase, adding more Snap Servers or Guardian Servers is simple and requires no network downtime. In addition, the DiskXtender Appliance Edition software is easy to install and maintain.
