It's always amusing to hear that a server went down because of a $10000 UPS hardware failure, where a dollar store power strip would have effectively been more reliable. Or when a misconfigured RAID array wipes all data on all drives. Or when the server can't boot because all its drives are on the SAN. Or when nodes of an active/passive cluster lose connection to each other and start a rapidfire cycle of grabbing active status. I still think all these redundant systems are useful, especially when properly implemented, so I'm not trying to make any grand point above. I'm just saying it never gets old to hear that the most recent bout of downtime was caused by the downtime-preventing equipment or system itself. Never gets old.

It’s important to know that preventing and avoiding disasters is just as essential as being able to recover from them. Redundant power, cooling and server architectures can limit the impact of disasters or even completely eliminate them. I’m seeing more and more hospital data centers deploying dual bus power architectures in their data centers to maintain several 9’s of availability.
