I work at a small shop who was badly burned by Sun/Oracle. :-)

It's not that I believe in overprovisioning I think. It's that if data is really that critical, and it's availability is critical, then that has to be taken into account during planning.

Everything fails at some point. The Enterprise Storage Vendors would have you believe their stuff doesn't. In practice it's pretty scary when the black box doesn't work as advertised anymore though _after_ you've made it the centerpiece of your operations.

So with those lessons learned, our replacement efforts took into account the level of availability we wanted to achieve.

I did go off on an NFS tanget. Sorry. But this article was about block-storage, which is a different beast from what you describe.

Seeing all networked storage lumped together is like seeing: FastCGI isn't 100% reliable, which is why I hate two-phase-commits.
