Exadata now supports Oracle VM with trusted partitions
Much more flexible licensing, e.g. for specific options
Separation of network zones
Separation of classes of database, e.g. with different service level
Benchware recommendation
Use database virtualization [1] instead of server virtualization
Use RAC One Node to move database services between server
Oracle VM
CPU: 2 sockets, 36 cores
X5-2 Server System
Virtual Server 1 Virtual Server
