O module 0, port 0) in a string.
Controller 2 HBA ports 0 and ports 1 connect to the third Drive Enclosure

(I/O module 1, port 0) in strings that support three or more Drive
Enclosures.
Controller 2 HBA ports 0 and ports 1 connect to the second Drive

Enclosure (I/O module 1, port 0) or to the first Drive Enclosure (I/O module
1, port 0) in strings that support less than three Drive Enclosures.
I/O module 0, port 1 connects to the second Drive Enclosure (I/O module 0,
•
port 0) and to the third Drive Enclosure (I/O module 0, port 0) in a string.
I/O module 1, port 2 connects to the fourth Drive Enclosure (I/O module 1,
•
port 0) and to the fifth Drive Enclosure (I/O module 1, port 0) in a string.
Note: The Oracle FS System supports three hops from the HBAs.
Drive Enclosure SAS Wiring Diagrams
The following wiring diagrams show the cabling of Drive Enclosures for one
string in a system. The same cabling pattern applies to all of the strings in a
system.
Note: The following wiring diagrams show DE2-24P Drive Enclosures. Note the
position of the SAS ports and the reverse orientation of the two I/O modules on
the DE2-24P Drive Enclosures. Conversely, the two I/O modules on the DE2-24C
Drive Enclosures have an identical orientation. Remember the orientation of the
I/O modules and the location of the SAS ports as you cable the system.
The following figure illustrates the SAS cabling for one Drive Enclosure string
containing one Drive Enclosure.
