The PS704 double-wide blade base planar holds the same components as the PS703
single-wide blade with the exclusion of the SAS controller, which is located on the SMP
planar. The PS704 double-wide blade SMP planar also has the same components with the
exclusion of the USB controller. This means that the components are doubled for the PS704
double-wide blade as compared to the PS703 single-wide blade except for the SAS controller
and USB controller. See 2.7, "Internal I/O subsystem" on page 55 for more details.
Figure 2-2 on page 39 shows the PS704 layout.
