Storage capacity - AWS Prescriptive Guidance

Storage capacity

Amazon RDS for Oracle supports the following AWS storage types:

  • General Purpose solid-state drive (SSD): gp2, gp3

  • Provisioned IOPS SSD: io1, io2

  • Magnetic

The storage types differ in performance characteristics and price. You can tailor storage performance and cost to the needs of your database workload.

Amazon RDS Custom for Oracle supports SSD storage type gp2, gp3 and io1. Magnetic storage isn't supported.

The maximum IOPS and throughput per RDS instance depends on the selected storage type and instance class. For more information, see Amazon RDS DB instance storage.

Amazon RDS for Oracle provides storage autoscaling that can automatically scale storage capacity in response to growing database workloads, with zero downtime. Amazon RDS storage autoscaling continuously monitors storage consumption. Capacity scales up automatically when actual utilization approaches provisioned storage capacity. There is no additional cost for enabling the storage autoscaling feature. You pay only for the storage that is provisioned.

Amazon RDS Custom for Oracle doesn't support storage autoscaling. You must manually provision storage.
