This document specifies requirements and recommendations for the type of risk assessment to be employed concerning seismic activity and earthquakes in relation to data centres. In addition, it describes design concepts that can be employed as mitigation actions within the construction and other design elements of data centres.

ISO/IEC TS 22237-7:2018 specifies processes for the management and operation of data centres. The primary focus of this document is the operational processes necessary to deliver the expected level of resilience, availability, risk management, risk mitigation, capacity planning, security and energy efficiency.

The secondary focus is on management processes to align the actual and future demands of users.

This document specifies requirements and recommendations concerning the physical security of data centres based on the criteria and classifications for “availability”, “security” and “energy efficiency enablement” within ISO/IEC 22237-1.
This document provides designations for the data centre spaces defined in ISO/IEC 22237-1.
This document specifies requirements and recommendations for such data centre spaces, and the systems employed within those spaces, in relation to protection against:
a) unauthorized access addressing organizational and technological solutions;
b) intrusion;
c) internal fire events igniting within data centre spaces;
d) internal environmental events (other than fire) within the data centre spaces which would affect the defined level of protection;
e) external environmental events outside the data centre spaces which would affect the defined level of protection.
NOTE Constructional requirements and recommendations are provided by reference to ISO/IEC 22237-2.
Safety and electromagnetic compatibility (EMC) requirements are outside the scope of this document and are covered by other standards and regulations. However, information given in this document can be of assistance in meeting these standards and regulations.
Conformance of data centres to the present document is covered in Clause 4.

ISO/IEC TS 22237-5:2018 addresses the wide range of telecommunications cabling infrastructures within data centres based upon the criteria and classifications for "availability" within ISO/IEC TS 22237‑1.

This document addresses power supplies to, and power distribution within, data centres based upon the criteria and classifications for “availability”, “physical security” and “energy efficiency enablement” within ISO/IEC 22237‑1.

This document specifies requirements and recommendations for the following:

a) power supplies to data centres;

b) power distribution systems to all equipment within data centres;

c) telecommunications infrastructure bonding;

d) lightning protection;
