Cost
Fail-over

RAC will cost far less. I recently priced an identical system Sun vs Dell. Same number of CPUs. Sun was $750K ... Dell/NetApp ... 1/3 the price after counting the cost of the RAC licenses to Oracle.

Remember without RAC ... to purchase backup capability requires duplicating everything. And even with that you won't have subsecond failover.
