In the PS704 blade, the SAS controller is located on the SMP planar. A total of eight SAS
ports are used in the PS704 blade, four of which are used on the SMP planar and the other
four are routed from the SMP planar to the base planar. So for each planar of the PS704 there
are two ports for each DASD slot and two ports for each CIOv connector, as shown in
Figure 2-25.
