SAS Wiring Diagrams (Controller to Controller)

Complete back-end data path redundancy is accomplished by providing Controller 1 and Controller 2 access to the data path channels for I/O module 0 and I/O module 1 at all times during normal operations:

The SAS connections between the Controller HBAs provide access to the data path channels through HBA port 2 and port 3.
Controller 1 accesses the data path channels for I/O module 0 through direct SAS connections to the Drive Enclosure strings through HBA port 1 and port 2.
Controller 1 accesses the data path channels for I/O module 1 through Controller 2, HBA port 2 and port 3.
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 figure illustrates the SAS cabling between the Controllers.

SAS Wiring Diagrams (Controllers to Drive Enclosures)

All of the SAS cables that connect Controller 1 to the Drive Enclosures attach to I/O module 0, port 0 on the Drive Enclosures. All of the SAS cables that connect Controller 2 to the Drive Enclosures attach to I/O module 1, port 0 on the Drive Enclosures

The following figure illustrates the SAS cabling of the Controllers in a base system that is configured with two Drive Enclosure strings.

Note: The colors of the cables that are shown in the figure are for illustration purposes and do not reflect the actual colors of the cables that are used to cable the Oracle FS System.
