DB System Storage
The storage performance of HeatWave Service scales with the storage size allocated to the DB system. You can manually increase the storage size of your DB system when required or enable automatic storage expansion to allow the storage size to expand automatically on demand.
You cannot limit or edit the IOPS of the storage. You must provision the storage size based on your data size and performance requirements.
HeatWave Service uses the Block Volume service Higher Performance option over iSCSI. The final performance results may vary for different shapes and scenarios. It is recommended to perform benchmark analysis during your Proof of Concept testing to verify your environment configuration has adequate performance for your application requirements.
The storage throughput can also be limited by the maximum network bandwidth of the DB system's shape.
Initial storage size | Number of volumes | Maximum storage size |
Between 50-400 GB | 1 | 32 TB |
Between 401-800 GB | 2 | 64 TB |
Between 801-1,200 GB | 3 | 96 TB |
Between 1,201-1,600 GB | 4 | 128 TB |
Between 1,601-2,000 GB | 5 | 128 TB |
Between 2,001-2,400 GB | 6 | 128 TB |
Between 2,401-2,800 GB | 7 | 128 TB |
Between 2,801-3,200 GB | 8 | 128 TB |
Between 3,201-3,600 GB | 9 | 128 TB |
Between 3,601-4,000 GB | 10 | 128 TB |
Between 4,001-4,400 GB | 11 | 128 TB |
Between 4,401-4,800 GB | 12 | 128 TB |
Between 4,801-5,200 GB | 13 | 128 TB |
Between 5,201-5,600 GB | 14 | 128 TB |
Between 5,601-131,072 GB | 15 | 128 TB |
If you create a DB system with a small initial storage size and increase the storage size multiple times larger later, the storage performance could be limited by the less than optimal number of volumes.
The storage size of a DB system can be increased manually or automatically. See Increasing the Storage of a DB System and Enabling or Disabling Automatic Storage Expansion. Increasing the storage size does not increase the number of volumes allocated to the DB system during its creation. Whenever the storage size is increased, the billing for storage usage will increase accordingly.
