Ugh, I managed to fatfinger-delete my parent comment, sorry.

(the essence was what you quoted: I claimed most people don't need these advanced SAN-features anymore because they don't need SANs in the traditional sense anymore)

Anyway, I'll just concede that OP aiming for feature-parity with commercial SAN's is indeed nonsensical.

The majority of mid to large sized companies run entirely on SANs

For large companies who bought into EMC/NetApp that may be true.

For small and mid-sized companies that's definitely not my experience.

Every company that runs on AWS is dependent upon SAN (eg, EBS). I imagine it's similar for other cloud services.

Just because you've never seen one or had to deal with one directly does not mean you're not dependent on one.

I think the discussion was about running your own SAN, i.e. creating your own EBS.

As it happens EBS itself is not backed by a SAN either. According to the rumors it's implemented using either DRBD or GNBD.
