yes, sorry, ultra 320 wide.

Exactly how many channels and drives?

one channel, 2 OS drives plus the 45 drives in the array.

Given that the drives only have 4 ID bits, how can you have 47 drives on 1
cable?  You'd need a minimum of 3 channels for 47 drives.  Do you have some
sort of external box that holds X number of drives and only uses a single
ID?

yes, I'm useing promise drive shelves, I have them configured to export 
the 15 drives as 15 LUNs on a single ID.

I'm going to be useing this as a huge circular buffer that will just be 
overwritten eventually 99% of the time, but once in a while I will need to 
go back into the buffer and extract and process the data.
