Realtime replication is expensive. Make sure you REALLY need that, as
it can double (or more) the price of your storage system, AND reduce
your storage sync performance greatly.

I'd start with:
- get oracle's quote for their unified storage appliance. Make sure
you get the one with SSDs. It should be cheaper than netapp.
- look into nexenta on whatever hardware they recommend (AFAIK
supermicro or dell/HP boxes should be good)

If both are still too expensive, the last path would be your own
home-brew solution using either openindiana or linux+drbd.
