Controller Nodes
The controller node caches and manages data in a system providing a comprehensive, virtualized
view of the system. The controller nodes are located at the rear of the node enclosure.
The HP 3PAR StoreServ 7200 Storage system contains two nodes numbered 0 and 1 (see
Figure 3 (page 7)). The HP 3PAR StoreServ 7400 Storage system has either two nodes or four
nodes. The four-node configuration is numbered 0 and 1 on the bottom, and 2 and 3 on the top
