Nodes Types

Can somebody explain AMPless Node, PE only Node, FiCon node?

What is their purpose and how they affect overall capacity of TD?

Re: Nodes Types

They are similar. They don't affect overall system capacity other than max sessions allowed. AMP-less / PE-only are two names for the same thing.

These are server nodes connected via BYNET but with no (external) disk. The purpose is to allow more total concurrent sessions to be connected (by defining additional PEs beyond the default of 2 per normal database node), or provide more network throughput beyond the default of one gateway and adapter (pair) per per normal database node, or to provide mainframe connectivity ( FICON node).

Re: Nodes Types

Could you please elaborate the purpose of having them?Do we need to have them?

What are application node and SWS node?

Re: Nodes Types

The term "application node" is an older name for what is now generally called a Teradata Managed Server. It is a server provided by Teradata that is not running Teradata database software.

Think of a Service WorkStation (SWS) as a "hardware console" used by Teradata Customer Support.

SWS and App Node are same?

Re: Nodes Types

No, they are entirely different.

An SWS may or may not be a separate physical node. It is used as the service entry for the system.
