Duwe

Hello, I'm fairly new to sccm, and i'm trying to get wsus and sccm to work properly, my problem is however that i dont have a spare 2TB to store all the updates it wants to download, now i've seen the option in wsus to auto approve the updates, but have clients download them from the MS update site, problem is, sccm keeps reseeting it back to storing the files locally, which continuously fills up the available hdd space (60gb). Is there any way to have it use the above mentioned wsus setting? Or will i need to buy a bunch of large drives to put in the server? I'm mainly using this to be able to use MS FEP, which actually works fine, and updates from MS.
