Let say you have dual channel U160 controller and you are have building external drive array of 10 U160 15K IBM drives.
Is it better to connect one channel to all the 10 drives or have a split backplane of 5 drives and connect each channel of the controller to each backplane ? I am going to create one raid 5 array with speed/redundancy as the primary goal.
I have the controller and the drives, so if you guys have any suggestion please just throw it in.
Btw, since each of my controller channel have the bandwidth of 160Mb, if I use both of the channel and create only one array I'll get theoratically 320Mb bandwidth, am I correct ??
