It is a pre-configured combination of hardware and software that provides a infrastructure for running Oracle Database. It consists of a database layer and a storage layer connected through an infiniband network. The database layer consists of Sun servers and runs Oracle 11gR2 software and normally Oracle RAC is deployed on database node. The database layer uses ASM to map to the storage layer. The storage layer also consists of Sun Servers and runs Oracle Storage server software. Exadata's exclusive features are smart scan, Hybrid Columnar Compression, and Storage Indexes.
Oracle Unbreakable Database Appliance (OUDA) is a completely integrated highly available (HA) database system in a single box. OUDA is an appliance and it contains storage, servers, operating System, and web-based monitoring tool (database control) within one box. It provides a ready-to-use, clustered database solution that includes both hardware and software optimized to work together.
Exadata is not an appliance, OUDA is. A server appliance is a computer for specific tasks, such as handling email or storing data, and a database appliance is just that; a computer to handle database. It is meant to be bought, brought into data center, plugged in, data loaded, and then gave access to the user, as you would do with any other appliance. But courtesy to Oracle's inherent architecture, you can customize, tweak and tune the appliance parameter according to your requirement.
OUDA is geared towards small and medium- sized business, whereas Exadata is for the big guns.
