Single-Controller
Topologies and
Dual-Controller
Topologies
If you are creating a topology for a controller tray or a controller-drive tray that
contains only one controller, you can attach only drive trays that contain a single
environmental services module (ESM). Do not attach a drive tray that contains two
ESMs to a single-controller controller tray or a single-controller controller-drive tray.
Copper Cables and
Fiber-Optic Cables
You can use a combination of copper cables and fiber-optic cables to connect the
drive trays to a controller tray or to a controller-drive tray. However, when a drive
tray communicates with the controller tray (or the controller-drive tray) indirectly,
through another drive tray, the connections between the drive tray and the controller
tray (or the controller-drive tray) and between the two drive trays must use the same
type of cable. Fiber-optic cables are required for host connections.
