N+1 and N+2:N+1 and N+2 Redundancy describes a system configuration in which multiple components (N) have at least one independent backup component to ensure system functionality continues in the event of a system failure. To be at a level of N+1, the overall system integrity should not be impacted by the failure of any one component, and should continue to function at acceptable performance levels after the loss of any component.

US Secure Hosting Center FactsThe colocation data center was built by the United States government as a communications facility, during the cold war era in the years following the Cuban Missile crises. It is not a converted missile silo. It is not built in an abandoned mine. It was not built in a cave. It was purpose built as an underground hardened communications facility solely to protect critical communications infrastructure. Entirely underground construction. Designed to operate for over two weeks entirely self contained. Operational as a colocation data center since 2002. Sub micron air filtration designed in to data center to filter air against chemical, biological, or radiological threats. Designed to withstand and continue to operate during, yes during, that is not a typo, and for two weeks after the detonation of a 20 megaton nuclear weapon at a range of 2.4 miles from the facility, and 1 megaton at one mile. It is built to survive either an air burst, or a ground burst. And it was designed to operate for this period of time with half of it's systems inoperable. Fully wrapped in a continuously welded seam quarter inch thick steel as an EMP shield. 100db of attenuation. Designed to operate during and after the over-pressure wave, and 800+ mile per hour winds created by a 20 megaton nuclear weapon. The colocation data center has:
The facility is over 200 feet in elevation higher than the nearest flood plain. Nearest flood plain is over two miles away. No municipal water supplies within two miles of the property. Redundant water wells, provide water on site, large water storage allows operation for two weeks upon simultaneous failure of both wells. Rural location. Away from any population centers or other structures that could be considered a target for terrorism. More than three miles of buried geothermal tubing on the data center campus provide a heat sink for the geothermal heat pump cooling system. Zero common points of failure. Zero exposed above ground critical infrastructure. Entire facility, including all critical infrastructure, such as generators, fuel, and air-conditioning condensers that are typically exposed in even the most "hardened" of data centers, are located entirely below ground. Zero shared tenants on site. Ability to survive multiple contingency situations. Over three thousand square feet data center floor space is immediately available. |
