In the DC3 drive cage, two FC-ALs, each providing four small form-factor pluggable modules to
service the drive cage. Figure 21 (page 69) 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.
FC 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 FC, 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, the type of network adapters, and
number of network adapters are configurable. The number of controller nodes each system model
can accommodate is summarized in Table 9 (page 70).
