Capacity Limits for Exadata Database Service on Exascale Infrastructure

Minimum VM Cluster Size

• Single-node VM cluster
• 8 total ECPUs per VM
• 220 GB (for 26ai) and 260 GB (for 19c) file system storage per VM
• 300 GB Exascale Vault database storage per VM cluster

VM Scalability Options

VM clusters can be scaled quickly and easily to meet your demands:

• It is possible to enable a subset of the total ECPUs assigned to the VM.
• When you enable more of your reserved ECPUs for the VM, you can scale the ECPUs without restarting the VM.
• You can scale memory in 2.75 GB increments per total ECPU.
• You can perform hot additions or removals of VMs
• You can scale VM storage (however, scaling VM storage requires a restart).
• You can perform live, online scaling of Exascale database storage
