Hi,
The server supports Ext2 and Ext3 so your best bet is to juggle around your data so you can install one disk in the server then transfer the data over, its going to be a bit of messing around but worth it.
take a look here,

check out the server running there.
Also go here
http://www.serverelements.com/documentation.php and grab yourself the manuals and Hardware ref manual and have a good read and see if your hardware is supported? any problems just ask and i am sure someone will guide you.
