Controller Nodes

The controller node is a component in the storage system that works to cache and manage data
in a system and to provide hosts with a coherent, virtualized view of the system. Controller nodes
are located in the rear of the node enclosure and are numbered 0 and 1 on the bottom and 2 and
3 on the top.
The HP 3PAR StoreServ 7200 Storage system includes two nodes. The HP 3PAR StoreServ 7400
