Wowser...
Sorry I forget a lot of the world doesn't have budgets to do what I am used to at work. All of our PC servers are 100% diskless we leverage our IBM sytem i5 dasd to handle our server storage space. Need another drive no problem just create it and link it on mini computer. And we run 6 drawers of disks all configured for device parity protection we can lose up to 16 drives as long as we dont drop more than 2 in any 1 set we just pop one out and slide one in.
Amazing I must assume you have physical server hardware in your locale?
Any more most sites use a hosting service....
The amount of traffic this site gets you have to be spending some big bucks on a lease line for your POP.
I am impressed if my above assumptions are correct.
