And in case of database it doesn't give you much. You still need 2 nodes for redundancy, if you don't need a rack's worth of storage for that database, using SAN for that is waste of money.
I know the corporate idea of "everything on SAN, nothing outside of SAN" very well, it's just plainly solving political problems, not techncial ones.

One major benefit that SAN-backed database storage provides us is, when combined with VMs, enables us to spin up another database instance against already existing data in the SAN (i.e. a staging DB that looks at prod data).
