OVH Server Partitioning

Hey,
I need a little help with partitoning my centos seedbox from ovh.
I have the following server: http://www.ovh.co.uk/products/superplan_mini.xml

The server has 2 harddrives. How do I partition through OVH to fully be able to use both harddrives for utorrent?

Think you need to reinstall from the Control Panel and make it a RAID0 installation. But to check if you can do it yourself, why not contact OVH supportphone?

Ow, and for your info; in RAID0 it's quite fast...
