Well, if you think you're going to get high performance and super
redundancy on cheap hardware, you need to think again.  ECC memory isn't
cheap either, but if you care about your data, you have to decide whether
it really needs to be protected.

No, you don't necessarily need fibre.  Some people do this over copper-based
LAN links.
