A controller node contains two controller slots and two on-board Ethernet ports. See
Figure 5-8 for specific port type assignments.
Figure 5-8. Numbering for Dual-Port Fibre Channel Adapters in the Controller Node PCI Slots
Each Fibre Channel adapter in a PCI slot has two or four Fibre Channel ports. Fibre Channel
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, horizontally.
Inside the controller node are data cache DIMMs and control cache DIMMs.
■ Data cache DIMMs are located in data cache slots 0 through 2.
■ Control cache DIMMs are located on control cache slots 0 and 1 (Figure 5-9).
