Nope... Just manages to find an OLD schematic of the network layout, it didnt actually have an array controller/RAID controller. It seems that in its past life the server was just a processing unit and that the HDD's were infact kept externally in seperate racks! No wonder there was no controller! D'oh!
Thanks for the help anyway, must got and see if I can steal a controller fromsomewhere now... ;o)
