Hey Veer,

Tera-data Drive is the thing used for Physical expansion in terms of memory. Expanding the warehouse may consist of adding nodes to the present configuration. If your environment is 100% busy in business hours then expansion in terms of Nodes will be the better option as it will make the data distribution and retrieval good. expanding in terms of a memory drive will help but may raise an issue with SKEW....!

Hope this help to some extent.

Waiting for Teradata masters to comment

Thanks
