Subj:   Re: Scalability of External Storage
From:   Yen Tsai


That is not true. While, it is always better to have a balanced system (balance between CPU, memory, and disk storage) for optimal performance of the system, one can always reconfigure the system if the needs have changed. We have configure Teradata systems with a range of disk storage per vproc, depending on the workload.

This means that if you add disk storage, the system may have the disk space for the workload, but it may be limited

by other system resources, such as CPU or memory. You will need more analysis of your current system workload with the resource usage statistics before determining whether just adding disk storage will improve the performance on your system. It does sound as if your system may be limited by other system resources and not just disk storage...
