PE 4600: Splitting backplane - daughter card, please help!

I have re-framed my yesterdays post:

PE 4600 (system spec given below):
I am planning to add a daughter card to split the backplane to 2x8. With 
this I was told I will be able to setup two arrays separate for each 
channel in RAID. I wanted to put 3x18G 10K hard disk in one array and in 
another two separate 146G hard disk containers. The main purpose of this is 
to get a better computational performance with the 3x18G 10K hard disk 
array and use the separate 146 hard disks for file storage. I would like to 
know if I am in the correct path or am I doing something wrong? Also I was 
wondering will my PE 4600 will have two SCSI channels so that I can put the 
two arrays in different channel. If so I want to know if this can be done 
with bios setup or does it require any physical connections or cabling to 
be done. I am confused with the connection between SCSI and RAID controller 
so if you could help me understand better it would be great.
