2.3 Using Isolation Policies

Oracle Exadata Database Machine supports multiple isolation levels.

Organizations wanting to consolidate IT infrastructure, implement shared service architectures, and deliver secure multitenant services should isolate services, users, data, communications, and storage. Oracle Exadata Database Machine provides organizations the flexibility to implement the isolation policies and strategies based on their needs. The following are the secure isolation levels of Oracle Exadata Database Machine:

• Isolating Network Traffic
  Oracle Exadata uses multiple networks to segregate network traffic.
• Isolating Databases
  Use operating system controls and database features to enable database isolation.
• Isolating Storage
  Oracle Exadata storage is isolated from the rest of the architecture through the use of a RDMA Network Fabric (InfiniBand or RDMA over Converged Ethernet (RoCE)).
