What is a clique?


What is a clique?

A clique is a set of Teradata nodes that share a common set of disk arrays which are connected in daisy chain network to each disk array controller.
Cliques provide data accessibility if a node fails for any reason,  Proms are distributed across all nodes in the system. Large multiple node systems will have clique mechanisms associated with them
