Amazon RDS for Oracle and SQL Server

Now support up to 256 TiB storage size, a 4x increase in storage size per database instance. Customers can add up to three additional storage volumes in addition to the primary storage volume, each up to 64 TiB storage, to their database instance. Additional storage volumes can be added, scaled up, or removed without application downtime.

Customers can scale database storage beyond the maximum storage size available in the primary volume, temporarily add volumes for short-term needs, and optimize cost performance by using a combination of high-performance and general-purpose volumes.

What to do

Additional storage volumes are available in all commercial AWS Regions and the AWS GovCloud (US) Regions.
