Amazon RDS for SQL Server increases storage limits for gp3 volumes

dataawsengineeraws-rds
feature

Amazon RDS for SQL Server now supports significantly larger and higher-performing General Purpose (gp3) storage volumes. This update allows for larger databases and improved I/O performance, benefiting demanding workloads like OLTP and analytics systems. Customers can scale individual volumes up to 64 TiB and provision up to 80,000 IOPS and 2,000 MiB/s throughput, with additional volumes further increasing capacity per instance. Pricing remains the same, with charges based on provisioned storage, IOPS, and throughput.

  • Increase maximum size for gp3 storage volumes

    Amazon RDS for SQL Server now supports scaling gp3 volumes up to 64 TiB, a four-fold increase from the previous 16 TiB limit. This allows for larger SQL Server databases to be hosted on RDS.

  • Increase provisioned IOPS and throughput for gp3 volumes

    The maximum provisioned IOPS for gp3 volumes has increased to 80,000 (5X increase), and throughput to 2,000 MiB/s (2X increase). This provides better performance for I/O-intensive workloads such as high-throughput OLTP and large-scale analytical systems.

  • Support for additional storage volumes per DB instance

    Customers can now configure up to three additional gp3 or io2 volumes per DB instance, increasing the total storage capacity to 256 TiB per instance. This offers greater flexibility for managing large datasets.

Notes (1) ›
  • No change to pricing model

    The pricing for Amazon RDS for SQL Server remains the same, with customers paying for the storage consumed and any IOPS and throughput provisioned beyond the default baseline. There are no additional costs associated with these increased limits.
