Like its predecessors, the standard is organized around :
The standard specifies minimum requirements across several critical data center subsystems:
Decide your uptime tier. Most data centers are (concurrently maintainable). Only hospitals and financial exchanges need Tier IV . tia942c pdf full
TIA-942标准自2005年问世以来，便成为全球数据中心设计人员、业主、顾问、供应商和运营商的首选参考资源，其广泛影响力覆盖超大规模数据中心到企业机房等各类设施。作为美国国家标准学会（ANSI）授权的规范，TIA要求其标准每五年进行一次修订、确认或废止。
This is the longest section. Major changes in Revision C: Like its predecessors, the standard is organized around
If you are designing AI/HPC clusters, you must use Revision C. If you are building a small server room for a bank (under 10kW/rack), Revision B is likely still sufficient, but not compliant best practice.
