so I still need to set up the luns with an LVM? and then put one disk group on
each LUN.
I think I got it.

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.
