I follow.  

So per my original post.  If I elect to purchase
system with RHEL installed [even though from what I
gather it probably makes no sense to since CentOS is
it's superset and is free], when the RHEL subscription
runs out after the first year, it will make no
difference if i use yum to update the system from the
CentOS repos going forward?  Those CentOS rpms will
install and run seamlessly on the original RHEL
install?  It seems like they should be 100% compatible
from what you're saying but thought I'd doublecheck.

They are shipping now with choice of SAS 5/ir or PERC
5/ir.  The latter is more sophisticated and more
expensive.  It looks like the PERC is an LSI based
card.  I'm not sure what the SAS 5/ir chipset is based
on but I'm leaning towards it.  Will wait to hear back
from Dell on it.

Is there any way to see what raid and sata drivers are
available in a CentOS release without having to
download and install an rpm?  If not which rpm would
contain the drivers, the base kernel?
