True, but it's not as though the 10X expense is for nothing. A SAN enables a lot more than local storage. I didn't mean to suggest that there wasn't a way to achieve lower costs on storage hardware directly, just that in practice, for a variety of reasons, that quoted cost is not representative.
- ilyt 3y agoAnd 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.
- pgwhalen 3y agoYour understanding of SAN usage is narrow, and incorrect in the case of my organization. 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).
