Teradata Aster Analytics on Azure provisions Azure premium storage for storage purposes.
Azure Premium Storage provides the following key implications:
- Provides the highest reliability among the storage options.
- Offers data persistence independent of a running VM.
- Allows shutdown of a VM between sessions to reduce costs.
- Provides lower performance compared to local storage.
- Costs less per GB than local storage.
- Allows for expandable storage through attachment of additional disks.
When deploying Teradata Aster Analytics on Azure, for each of the four VM size options (DS12_v2, DS13_v2, DS14_v2, DS15_v2), you have the option to choose 1TB, 4TB, or 8TB as data disk size.
