Two SAS controllers but only 1 SAS controller!

I have investigated further and have learnt a very useful but painful lesson. When you look at the P730 from the HMC you see two SAS controllers, 1 on P1/C8 and the other on P1/C18/T1. I stupidly assumed these were 2 seperate controllers but no it appears they are the same controllers and all disks are fitted to both! Where is the sense in that? Come on IBM answer that question!
