I don't believe there is support for drives over 128GB (in powers of 2
format, 131GB decimal) in AS 2.1 due to kernel limitations.  ES3/AS3
should handle them, as RH tweaked the kernel.

The difference between ES and AS is that AS is limited to 2 processors
in SMP configuration (I think it's 2), while ES is limited to 8.

BTW, I think you can rebuild the AS kernel to give you the 8 processors
if you want to, but that might violate your support agreement.
