Oracle Data Appliance (ODA)

Oracle Database Appliance (ODA) is a rack mounted "all-in-one" box supplied by Oracle. It contains 2 nodes, 2 networks, 2 power supplies and 2 sets of storage (magnetic disk or SSD) accessible to both nodes.
The 2 nodes talk to each other and to storage across an internal 40Gb/s InfiniBand network.
It can be virtualised or bare-metal. You can setup single instance databases, RAC-One (active-passive) or RAC (active-active) databases.
A whole new set of commands is used to interact with ODA - oakcli.
