TERADATA Architecture - parallelism?

Hi All,
Can you please tell me what is the component in TERADATA Architecture which is responsible for parallelism?
I mean if this component is removed, the system will no longer be parallel.
I think its the AMPs, Can you please confirm.

Hi Gaurav,
the whole architecture is responsible for parallelism.  Basically all the components are designed with parallelism in mind.
Also note that all components are designed with fault-tolerance, to protect the system from hardware and software failures.   So you do not easily loose a component due to incidents.
There is no reason to remove necessary components intentionally.

Parallel Database Extensions( PDE) is a software layer(interface) rich in sophisticated algorithms takes control of Teradata parallelism. It lies between the OS and Teradata server. Speed and linear scalibility are attributed to PDE. The management of I/O and task distribution within and across nodes are accomplished by way of PDE.
