EBS Storage

With EBS storage, the root volume for a Teradata Database on AWS instance and additional EBS volumes that you attach to the instance persist by default. Unless you set attached volumes to delete on termination, all data remains and storage-related charges continue to accrue. You can enable EBS storage deletion either when configuring an instance (see Launching an Instance Using Manual Launch) or after launching an instance (see Setting EBS Storage for Deletion on Instance Termination).

For Teradata Database, only the m4.4xlarge, m4.10xlarge, and m4.16xlarge instance types on AWS support EBS storage. Instance types supporting EBS storage may vary across other Teradata Database on AWS products.

If you are launching Teradata Database MPP instances, Teradata recommends using the m4.4xlarge, m4.10xlarge, or m4.16xlarge instance types. Since Teradata Database runs at the speed of the slowest node, using any of these EBS optimized instance types is important to get the maximum EBS volume bandwidth for your instance.
