Exadata X9M-2 Systems
Autonomous Database on Oracle Public Cloud
For Autonomous Databases deployed on Oracle Cloud, X9M-2 systems support elastic configurations instead of fixed shapes such as quarter rack, half rack, or full rack. X9M-2 systems are currently provisioned with a configuration equivalent to a quarter rack.
Should you need to provision an X9M-2 system with a different configuration, you have the flexibility to choose another value for database servers and storage servers within a valid range. The acceptable range of values is 2 to 32 for database servers and 3 to 64 for storage servers.
To provision an X9M-2 system successfully, the service limits for Exadata X9M Database Server Count and Exadata X9M Storage Server Count in your tenancy should be at least 2 and 3, respectively. Request a service limit increase from the Oracle Cloud Infrastructure console if required. Observe that the Exadata X9M Database Server Count and Exadata X9M Storage Server Count limits are defined as counts per availability domain. Refer to Requesting a Service Limit Increase for more details.
The table below lists the characteristics of an Exadata X9M-2 system on Oracle Cloud with its default database server and storage server settings.
| Property | Default Provisioning |
|---|---|
| Number of Compute Nodes | 2 |
| Total Maximum Number of Enabled CPU Cores | 252 |
| Total RAM Capacity (GB) | 2,780 |
| Persistent Memory (TB) | 4.5 |
| Number of Exadata Storage Servers | 3 |
| Maximum Database Size, No Local Backup (TB) | 152 |
