13.5.3 E-Class and F-Class Controller Node Numbering

InServ E-Class and F-Class Storage Servers have a different number of controller nodes

depending on the storage server model.

■ InServ E-Class Storage Servers always contain two controller nodes. The top controller node

is number 0 and the bottom controller node is number 1.

■ InServ F-Class Storage Servers contain two or four controller nodes. The controller nodes

are numbered 0-3 from top to bottom.

See Figure 13-12 for an example of controller node numbering in an InServ F400 Storage

Server with four controller nodes.
