Saturating an Infiniband (40 Gbps) link with disk I/O might be somewhat complicated.

A few PCIe SSDs should get you there (again if not CPU bound). You can put quite a lot in a single machine, they come in normal SSD form factor with backplanes. It would still be a bit higher latency than RAM, but much more capacity.

I think, he was assuming commodity 1Gbit/10Gbit on which most databases are run. Does anybody use Infiband to interact with their database? It would be interesting to hear from them.
