7. Data Center Tiers and Levels of Security

Data centers will continue to play a critical role in modern business operations, housing the infrastructure and applications that support a wide range of digital services. To ensure the reliability, security, and resilience of data center operations, the American National Standards Institute/Telecommunications Industry Association (ANSI/TIA) has established a set of standards known as the ANSI/TIA-942 Data Center Standards. These standards define four tiers of data center infrastructure, each with increasing levels of redundancy and fault tolerance. This section provides an overview of each tier and its associated level of security, as a way to inform strategies focused on holistic security of data centers.

Overview of ANSI/TIA-942 Data Center Standards

The ANSI/TIA-942 Data Center Standards provide guidelines for the design and operation of data center facilities, focusing on key aspects such as site location, architectural design, electrical systems, mechanical systems, and security. These standards are designed to ensure that data centers meet the requirements for availability, reliability, and security necessary to support critical business operations.

Tier 1: Basic Site Infrastructure

Tier 1 data centers are characterized by a basic level of infrastructure and are typically used for small businesses or non-critical applications. Key features of Tier 1 data centers include:

Non-redundant capacity components and a single, non-redundant distribution path serving the IT equipment.
Basic site infrastructure with no redundant or backup components.
Typically used for small businesses or non-critical applications where downtime can be tolerated.

While Tier 1 data centers provide a basic level of infrastructure, they do not offer the level of redundancy and fault tolerance required for mission-critical applications or services.

Tier 2: Redundant-Capacity Component Site Infrastructure

Tier 2 data centers build upon the basic infrastructure of Tier 1 facilities by introducing redundant capacity components. Key features of Tier 2 data centers include:

Redundant capacity components to support IT equipment, such as cooling and power systems.
A single, non-redundant distribution path serving the IT equipment.
Basic site infrastructure with redundant components for increased reliability.

Tier 2 data centers provide increased reliability and availability compared to Tier 1 facilities, making them suitable for small to medium-sized businesses or non-critical applications that require higher levels of uptime.

Tier 3: Concurrently Maintainable Site Infrastructure

Tier 3 data centers are designed to be concurrently maintainable, meaning that maintenance or upgrades can be performed on the infrastructure without impacting IT operations. Key features of Tier 3 data centers include:

Redundant capacity components and multiple independent distribution paths serving the IT equipment.
Basic site infrastructure with redundant components and multiple distribution paths for increased reliability.
Designed to be concurrently maintainable, allowing for maintenance or upgrades to be performed without downtime.

Tier 3 data centers provide a high level of availability and are suitable for medium to large businesses or critical applications that require continuous uptime.

Tier 4: Fault-Tolerant Site Infrastructure

Tier 4 data centers are the most robust and fault-tolerant facilities, designed to withstand a wide range of potential failures. Key features of Tier 4 data centers include:

Redundant capacity components and multiple independent distribution paths serving the IT equipment.
Fault-tolerant site infrastructure with redundant components and multiple distribution paths for increased reliability.
Designed to withstand a wide range of potential failures, including equipment failures, power outages, and natural disasters.

Tier 4 data centers provide the highest level of availability and fault tolerance, making them suitable for large enterprises or critical applications that require continuous uptime and protection against potential failures.

The ANSI/TIA-942 Data Center Standards provide a framework for designing and operating data center facilities that meet the requirements for availability, reliability, and security. By understanding the different tiers of data center infrastructure and their associated levels of security, organizations can select the appropriate tier to meet their specific needs and ensure the resilience of their data center operations.
