Yes my SAN (mostly redundant) could go down but at least I am redundant everywhere else. Running on a local server is not redundant at all and not fail safe.
The setup allows me to have any number of vm’s with single Microsoft licensing, this is less expansive then buying a server for every roles in my organisation and buying licenses for each of them.
Also, using vmotion, this setup allows me to do maintenance by removing my server from the cluster with no downtime. There is alot of advantages running this setup.

I would realy like to know what you propose as a good architecture for the SMB?

I believe the author mentioned that servers with local storage would be more reliable.

The SANs are in separated locations.

But one thing I feel is missing is recommendations to counteract this. If a company has the “inverted pyramid” in place, effectively limited by the SAN being a SPOF (even if it has dual controllers, and the storage array is RAID 5 or 6), then what is the solution? A redundant SAN?
