From time to time, we like to highlight a tool from the Resources tab on our website. Its called, Data Center Reliability Levels. It is a comprehensive chart that clearly outlines the various levels that a Data Center may be functioning at. We want to enable our potential clients and existing customers to quickly assess where their Data Center is at and then identify where they want it to be.

Check out the link or venture over to our Resources tab and see where your facility’s Data Center ranks! Then call us!

Data Center Reliability Levels

 

Numerical Ranking
Terminology
Summary Definition

1

Unreliable
  • Shared power and cooling
  • No generator
  • No fire separation (standard construction materials)
  • No fire suppression

2

Unreliable/Improved Power
  • Dedicated Unconditioned Power
  • Shared building cooling
  • No generator, no TVSS
  • Non-redundant air conditioning
  • No fire separation
  • Wet or no sprinklers

3

Unreliable-Improved Power/Cooling
  • Independent power and cooling
  • No UPS, generator or TVSS
  • Non-redundant dedicated A/C
  • No fire separation
  • Wet or no sprinklers

4

Conditioned
  • Dedicated power and cooling
  • Conditioned power (no UPS or generator)
  • Dedicated non-redundant A/C units
  • Limited fire rating (<1hr, wet sprinklers)

5

Isolated
  • Dedicated power & cooling systems
  • Single UPS (no back-up), No generator
  • Non-redundant dedicated A/C units
  • Fire rating of 1 hour
  • Limited / wet suppression

6

Improved-Isolated
  • Dedicated power, UPS and cooling
  • Redundant dedicated A/C units
  • No generator
  • Fire rating of 1hour
  • Smoke detection / pre-action sprinkler system

7

Reliable
  • Dedicated power, UPS, cooling systems
  • Redundant & dedicated A/C units
  • Single back-up generator
  • Fire rating 1hr
  • Intelligent detection system
  • Pre-action Sprinkler System

8

Reliable/Redundant
  • Dedicated & redundant power and cooling components
  • Redundant UPS, A/C, generators
  • Dedicated generators / single fuel system
  • Fire rating 1 hour
  • Intelligent Detection System
  • Pre-action sprinkler system
  • Optional gaseous fire suppression system

9

Highly Reliable
  • Fully redundant: (power train, cooling systems
  • Redundant UPSs, A/C, Generators, fuel systems
  • Physical segregation of redundant systems
  • Fire rating 1 hour
  • Intelligent detection system
  • Pre-action sprinkler system
  • Optional gaseous fire suppression system

10

Geographically Hardened & Redundant
  • All Redundant: (power train, cooling system, UPS systems, generators, fuel systems
  • Physical segregation of redundant systems
  • Fire rating of 2 hours
  • Intelligent detection system
  • Pre-action sprinkler system
  • Optional gaseous fire suppression system
  • Site is hardened for weather and geographic exposures
  • Location minimizes exposure to jurisdictional closure from hazardous spill, acts of terrorism, sabotage or similar risks

 This is a summary of BRUNS-PAK’s Reliability Scale. A more detailed breakdown of the architectual, electrical, mechanical, fire suppression, and security elements within the BRUNS-PAK 1-10 Scale is addressed in BRUNS-PAK’s initial consulting engagements.
