The drive storage in a coexistence system must be certified for its specific platform.
Contact your Teradata representative to confirm the exact version of the Teradata Database, the operating system, and PDE packages required for the platform.
There are two storage modes:
- Teradata Traditional Storage mode is the default storage mode for Teradata systems with HDD-only storage.
- Teradata Virtual Storage (TVS) is required for Teradata systems with hybrid HDD and SSD storage, and optional for Teradata systems with HDD-only storage. TVS provides functionality regarding how storage is configured and used in a Teradata system.
In 6800C coexistence systems, all storage drives are HDD storage drives. 6650 systems that contain EMC storage, whether it be EMC only or in a coexistence system with Teradata storage, must use Teradata Traditional Storage mode.
