Drive Cage Models
The T-Class and P10000 systems contain both DC4 drive cages. The DC4 is a 40 disk, 4
Gbps drive cage.
The F-Class systems only contain DC3 drive cages. The DC3 is a 16 disk, 4 Gbps drive cage.
DC4 Drive Cages and Ports and Cabling
The DC4 drive cages house ten drive bays numbered 0 through 9. Each drive bay accommodates
a single drive magazine that holds four disks. Figure 15 (page 61) shows a DC4 drive cage which
contain two Fibre Channel-Arbitrated Loop (FC-AL) modules:
The left side FC-AL has two ports: A0 and B0.
The right side FC-AL has two ports: A1 and B1.
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.
