Topics for auditing a datacenter

Answer:

First of all you must select competent and independent auditors to perform the audit (by independent you must understand people that are not involved with datacenter operations). After that you must identify which requirements are applicable to your datacenter, by means of identifying legal requirements, relevant risks and applicable controls. Once these issues are identified you should elaborate a checklist to help you cover these issues with proper questions and evidences to be verified.
