What type of redundancy can we expect to find in a datacenter of any tier?

In a datacenter, regardless of its tier classification, there is an expectation for emergency egress redundancy. This means that emergency exit routes are available to ensure that individuals can safely evacuate the facility during emergencies, such as power failures, natural disasters, or other critical incidents.

Emergency egress is crucial for safety and compliance with regulations, ensuring that in the event of an emergency, occupants can exit swiftly and safely without hazards or obstruction. This aspect is fundamental, and its implementation is often mandated by safety codes and standards applicable to all datacenters.

While full power capabilities, all operational components, and infrastructure redundancy are more prevalent in higher-tier datacenters, the presence of emergency egress is a basic safety requirement that is universally applicable to all tiers. This underscores the importance of prioritizing human safety even in the technical and operational aspects of datacenter design and security management.
