It is unlikely your storage array has the capability to present a multi-TB lun, or that from an administrative perspective you would want such a thing. ASM would be a fine way to evenly distribute IO across a series of reasonably sized LUNs. I think Paul's point was to not count on the striping from a performance perspective, simply an administrative ones.

So I don't need to ask the SAN admins to set up a series of LUNs? They can just make me one big mount point for my datafiles and it will be evenly distributed?

We may be talking 5 TBs/day of data we are inserting at full deployment plus 4 million queries.
