Martin911,
It would greatly help if you explained what you are trying to do so we could understand the problem (if there is one).
All servers can do Raid functions, but the drives can not be in basic mode if you do software RAID. If your server does hardware RADI, then make the RAID drives Basic drives.
If your problem is that you want to do clustering, then the problem is more complex, the servers must be hardware specified to be able to be cluster servers, and you must use the Advanced Server software.
If you are not using clustering, you do not need Advanced Server, and SQL runs just fine under the standard server, unless you need to cluster it.
HTH,
David
