Understanding Component Numbering

Controller nodes are loaded into the storage server midplane from bottom to top. Therefore,
for an InServ S800 storage system with only two controller nodes installed, those controller
nodes would occupy the lowest 4U of the midplane and would be numbered node 6 and
node 7.
As shown in Figure 2-10, 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 2-10. 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.
