Raid... controller ?<p>Your servers are virtualised with redundant hardware (if they&#x27;re not IaaS in the first place). There&#x27;s no &quot;rebuilding&quot; of the server. Have you ever actually managed a production environment in the last 10 years? We&#x27;re not even talking about a lot of money here.<p>A raid controller dying should either a) not bring down production or b) not be your problem anyway.
