nodes would occupy the lowest 4U of the midplane and would be numbered node 6 and
node 7.
As shown in Figure 3-10, a controller node contains six PCI slots numbered 0 through 5, from
left to right. 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.
Figure 3-10. Numbering for Dual-Port Fibre Channel Adapters in the Controller Node
In quad-port Fibre Channel adapters, the ports are numbered PORT 0, PORT 1, PORT 2, and PORT 3,
from top to bottom.
The controller node also has an Ethernet port and a maintenance port.
Controller nodes contain both control cache DIMMs and data cache DIMMs (Figure 3-11).
