As shown in Figure 3-13, a controller node contains six PCI slots. These slots accept PCI adapters
such as dual-port Fibre Channel adapters, iSCSI adapters, and Ethernet adapters. The controller
node also has a management Ethernet port (E0) and a maintenance port (C1).
Figure 3-13. Numbering for Dual-Port Fibre Channel Adapters in the Controller Node PCI Slots
Each Fibre Channel adapter in a PCI slot has four ports. Each iSCSI adapter in a PCI slot has two
or four ports. PCI adapters assume the numbers of the PCI slots they occupy.
■ In dual-port adapters, ports are labeled PORT 1 and PORT 2, from top to bottom.
■ In quad-port Fibre Channel adapters, the ports are numbered PORT 1, PORT 2, PORT 3, and
PORT 4, from top to bottom.
