Black Swan in the Data Center or How to Prepare for a Disaster

In today’s blog, I’d like to step away from the technical aspects of disaster recovery and focus on the human impact. With that in mind, I’d like to introduce you to one of my favorite books on the subject of predictability and inevitability: The Black Swan by Nassim Nicholas Taleb.

 

The book describes Black Swan events as unexpected and unpredictable. However, a person or organization can plan for negative events, and by doing so strengthen their ability to respond, as well as exploit positive events. Taleb contends in his book that people in general — and specifically within companies and enterprises — are very vulnerable to hazardous Black Swan events and can be exposed to high losses if unprepared.

 

Not if, but when!

 

Healing Data Centers with Bare-Metal Recovery

Phew. The worst is over. You have identified, caught and dealt with the virus that threw you and your bosses out of the comfort zone for days. You have shut down all the affected servers – the data center is safe.


Like a soldier returning from a mission, you are dreaming of a peaceful rebuilding of everything that was lost. However, that is not what your bosses, your colleagues, and your company demand. They need the data center and all applications back. For them, the downtime is not over. Not yet.


So what do you do? You sigh and prepare for a long routine – install operating systems on each server, service packs, updates, drivers, applications, application updates, settings, etc. You know it will take many long hours, if not days to complete – and with number of affected servers, you are facing an uphill battle. You pray for luck that everything goes smoothly, and you do not have to restart from scratch any of the servers.
