Drive Enclosure SAS Wiring Diagrams
The following wiring diagrams show the cabling of Drive Enclosures for one
complete string in a system. The same cabling pattern applies to all of the strings
in a system. Remember to distribute Drive Enclosures among the strings so that
all of the available SAS HBA ports designated for Drive Enclosures are used as
equally as possible.
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.
Figure 85: SAS wiring diagram for one string with one Drive Enclosure
The following figure illustrates the SAS cabling in a system that is configured
with one Drive Enclosure string containing two Drive Enclosures. The same
cabling pattern applies to all of the strings in a system. Remember to distribute
Drive Enclosures among the strings so that all of the available SAS HBA ports
designated for Drive Enclosures are used as equally as possible.
