Oracle Database Appliance, EXADATA Jr?

The Oracle Database Appliance saves time and money by simplifying deployment, maintenance, and support of high-availability database solutions. Built with the latest generation of the world’s most popular database—Oracle Database 11g—it offers customers a fully integrated system of software, servers, storage, and networking in a single box that delivers high-availability database services.

Fully Redundant Integrated System
The Oracle Database Appliance hardware is a single 4U rackmountable chassis containing two
Oracle Linux server nodes, each with two 6-core Intel Xeon processors X5675 and 96 GB of memory. The two server nodes are connected via an internal redundant gigabit Ethernet (GbE) interconnect for cluster communication, and each provides both 1 GbE and 10 GbE external networking connectivity. The appliance contains 12 TB of raw storage that’s triple-mirrored, offering 4 TB of resilient usable database storage. There are also four 73 GB solid-state disks for database redo logs to boost performance. To expand storage outside of the appliance, external NFS storage is supported for online backups, data staging, or additional database files. The appliance is designed with mission-critical requirements in mind, with hotswappable and redundant components.  The Oracle Database Appliance runs Oracle Database 11g, Enterprise Edition, and customers have the choice of running Oracle Real Application Clusters (Oracle RAC) or Oracle RAC
One Node for “active-active” or “active-passive” database server failover.

Ease of Deployment, Management, and Support
To help customers easily deploy and manage their databases, the Oracle Database Appliancefeatures Appliance Manager software for one-button automation to provision, patch, and diagnose database servers.

Pay-As-You-Grow Licensing 
The Oracle Database Appliance offers customers a unique pay-as-you-grow software licensing model to quickly scale from 2 to 24 processor cores without any hardware upgrades. Customers can deploy the Oracle Database Appliance with as few as 2 processors cores to run their database servers, and incrementally scale up to the maximum of 24 processor cores.
