Re:My home lab setup for highly-available Internet

My anecdata: I used to admin a SWIFT cluster. It was built by the manuals on IBM hardware, that included HACMP with quorum determined by a shared disk.
Nobody understood exactly how the cluster worked to the point that a correction my boss made on the physical connections, made us loose a couple of million of dollars in transactions not processed.
The funny part is, when the cluster was working fine, a takeover took at least 20 minutes. During that time nothing was "available". The thing is, no matter what, SWIFT Alliance took that time to properly close and open the DB.
