SANs are one way, Agreed, if you include fast interconects like SAS and exclude the network[1] requirement of SANs. sharding/distribution across multiple nodes another. I disagree, for the sam reason that doing so with iSCSI over ethernet isn't: too much added latency. Infiniband may help, but I have yet to try it empirically.
