TIA-942 was introduced in 2005 with the intention of addressing data centre infrastructure. The document sets out 4 levels of power availability, ranging from:-

Tier 1 - 99.671% availability - Single distribution path - no equipment redundancy
Tire 2 - 99.741% availability - Single distribution path - n+1 equipment redundancy
Tier 3 - 99.982% availability - Dual distribution paths - n+1 equipment redundancy
Tier 4 - 99.995% availability - Dual systems, both active - n+1 equipment redundancy

We have designed and built data centres up to tier 4 standard, incorporating multiple redundant power supplies. However, most tend to be a tier 2 system but with added distribution paths to increase the resiliency of the site.
