Scaling storage and performance

Information about scaling storage, and throughput for Db2® Warehouse SaaS Azure instances.

Each Db2 Warehouse SaaS BYOC Azure instance deploys single or multiple volumes based on the deployment type picked from the Engine Deployment page. Storage can be scaled up in increments based on the plan. The increments are available in the Db2 Warehouse SaaS BYOC Engine console.

Important: Db2 Warehouse as a Service instances include the Storage Autoscaler by default, no manual configuration is required.

In this documentation, we refer to storage capacity by using the unit GB (Gigabytes) to align with the industry standard terminology. However, the actual provisioning and billing of storage are based on GiB (Gibibytes).

The difference between GB and GiB lies in their numerical representation:

  • GB (Gigabyte) is a decimal unit, where 1 GB equals 1,000,000,000 bytes
  • GiB (Gibibyte), is a binary unit, where 1 GiB equals 1,073,741,824 bytes

A maximum of 3 scale attempts are allowed within a 24 hour period.
