Appendix A. Example Configurations
The diagrams in this appendix show some example configurations for the 7133. All the
configurations that are shown here are the simplest and provide the best ease of use.
If performance or availability are particularly important to the customer, however, more
complex cabling might provide a better solution; consult your marketing
representative for more details.
Under the standard SSA rules, you can mix any compatible SSA devices in a particular
SSA loop.
Simplest Configuration
A 7133 that is in base configuration includes four disk drive modules. These modules
are installed in the upper four slots at the front of the 7133. The other 12 disk drive
slots contain dummy disk drive modules. The disk drive modules are linked in groups of
four. Each group of four modules is linked to two external SSA connectors.
In the simplest configuration, the SSA loop is completed by connecting these two SSA
connectors to one of the two pairs of connectors on an SSA attachment in the using
system (see Figure 15).
