Amazon RDS for SQL Server supports read replica with additional storage volumes
Amazon Relational Database Service (Amazon RDS) for SQL Server now supports read replicas for database instances with additional storage volumes. Additional storage volumes allow customers to scale database storage up to 256 TiB by adding up to three storage volumes, each with up to 64 TiB, in addition to the primary storage volume. With this launch, for database instances configured with additional storage volumes, customers can create same-region and cross-region read replica database instances.
When a read replica is created for a database instance with additional storage volumes, the replica preserves the storage layout of the source instance, including the configuration of any additional storage volumes. After the initial creation, you can independently manage additional storage volume configurations on the source and read replica instances.
Read replicas with additional storage volumes are available in all AWS commercial Regions and the AWS GovCloud (US) Regions. Customers can start using this feature today through the AWS Management Console, AWS CLI, or AWS SDKs.
