2.2 Extending Elastic Configurations

Oracle Exadata is available in Elastic Configurations that consist of a number of database and storage servers up to the capacity of the rack, as defined within Oracle Exadata Configuration Assistant (OECA).

Additional database and storage servers can be added if space is available; see OECA for details. The upgrade process includes adding new servers and cables

Note:

It is possible to extend the hardware while the machine is online, and with no downtime. However, extreme care should be taken. In addition, patch application to existing switches and servers should be done before extending the hardware.
