Ok then you skimped on the 16 Cores.  Copying that data is fine and
dandy with me.  But don't count all your eggs until there hatched.  

It's just you have to understand something here don't rely on copying
any data from one single disk here now.  At least have for the primary
data to = 2 disks mirrored atleast.  It's ludicrous to have a 16 core
machine with one data disk.  That's is just completly insane in the IT
evironment I work in.  It's unheard of.

Check this out:  Lets Think:
That one single data disk dies or gets corrupted and you have your data
Stored Offsite like you plan on doing?  You dead in the water already.
How long will it take to grab the Offsite data.  Really think about it
now.  I am not being a "but" about it I'm just telling you what happens
in real life and has happened.
