In the DC3 drive cage, two FC-ALs, each providing four small form-factor pluggable (SFP) modules
to service the drive cage. Figure 19 (page 66) shows the rear view of a DC3 drive cage.
• FC-AL B has four ports, labeled Port B0 through Port B3, from bottom to top.
• FC-AL A has four ports, labeled Port A0 through Port A3, from top to bottom.
Fibre Channel cables connect the ports in the drive cage to the ports on the controller nodes. Each
cable is labeled to indicate the ports it uses.

Controller Nodes
System controller nodes use Fibre Channel, Gigabit Ethernet, and iSCSI ports to connect the storage
sever to your network, host computers, storage sever components, and to other systems.
Inside each controller node there are slots for network adapters, control cache DIMMs, and data
cache DIMMs. The number of controller nodes in each system, and the type and number of network
adapters is configurable. The number of controller nodes each system model can accommodate
is summarized in Table 9 (page 67).
