The process of extending an Oracle Exadata Database Machine Eighth Rack system is principally the same as extending any other Exadata rack. At a high level, the process involves the following stages:

1. Verify the preexisting Eighth Rack system configuration.

2. Perform any required hardware installation.

   During this stage, you may need to shut down servers to install some hardware components. Where required, servers would be shut down in a rolling manner to preserve overall system availability.

3. Configure the additional hardware resources.

   During this stage:

   • New database server resources are added to a database cluster.

   • New storage server resources are used to create additional grid disks, which can be used to extend existing Oracle ASM disk groups.
