Controller Nodes
The controller node is a storage system component that caches and manages data in a system and
provides hosts with a coherent, virtualized view of the system. Controller nodes are located in the
rear of the node enclosure.
The HP 3PAR StoreServ 7450 Storage system can contains two nodes or four nodes: node 0 and
node 1 in the lower controller enclosure, and node 2 and node 3 in the upper controller enclosure
in a system with four nodes.
