Oracle / Storage geeks: What are the alternatives to exadata for high-performance I/O with a rac system?

We are getting pretty close to buying an exadata setup and I'm trying to find viable alternatives that are cost-effective and deliver similar performance. We need to be running RAC for load balancing and fault tolerance, so I believe direct attached storage like SSD-arrays is not an option. Buying a dedicated SAN seems to be lower performance and higher cost than exadata. For benchmarking the exadata system we are looking at (1/4 rack) delivers 4.5GB/sec sustained I/O to disk. Our current SAN (which is overly shared) gives us approx 150MB/sec and our 4-nic dnfs systems to a netapp runs at approx 350MB/sec.
So assuming we need at least 3GB/sec and it cant be direct-attached what are other good options out there?
Lets just ignore the other features of exadata that make it fast like smart-scan. Thanks!
