Enterprise Data Centre

Understanding the physical and logical requirements is always important, regardless of the asset size or complexity, because this will allow you to identify the solutions that will properly support your need, without letting any gaps (if requirements are underestimated), or consuming unnecessary resources (if requirements are overestimated).

Considering that, without knowing your context and risks it is not possible to define practical solutions. What can be done is mention common practices (which should be evaluated considering your context and risks):

• physical segregation from other environments
• logical segregation of servers, networks and services
• redundancy of single points of failure (e.g., power cable, communication links, etc.)
