Thanks.  So there are things that can be done to tune the T2000?  We are
planing on setting up another T2000 (4core 8gb at the moment) for an
Oracle 10gR2.  When the time comes do you mind if I save your contact
info and maybe fields some questions your way when we begin the planing
of that system?  No Iscsi in my situation.  SO I'm guessing the on board
nics will do?

Thanks

Ben
