I've been asked to build a server that will house 2T to 4T of data, couple questions come to mind:
1. Is there any significance in going the virtual route? I'd prefer to go this route rather than creating more hardware.
2. To elaborate on the above question is there any compression when virtualizing?
3. Regarding hardware there may be other projects that large amounts of data are needed, one reason virtualization seems like a better route.
