Controller 2 accesses the data path channel for I/O module 1 through direct
SAS connections to the Drive Enclosure strings through HBA port 1 and
port 2.
•
Controller 2 accesses the data path channels for I/O module 0 through
Controller 1, HBA port 2 and port 3.
The following gure illustrates the SAS cabling between the Controllers.
Note: The colors of the cables that are shown in the gure are for illustration
purposes and do not reect the actual colors of the cables that are used to cable
the Oracle FS System.

All of the SAS cables that connect Controller 1 to the Drive Enclosures aach to I/
O module 0, port 0 on the Drive Enclosures. All of the SAS cables that connect
Controller 2 to the Drive Enclosures aach to I/O module 1, port 0 on the Drive
Enclosures
The following gure illustrates the SAS cabling of the Controllers in a base
system that is congured with two Drive Enclosure strings.
