Redundancia - Definiciones
N Requisitos Base (N = necesarios)
El sistema cumple con los requisitos basicos y no cuenta con ninguna redundancia.
N+1 Redundancia
La redundancia N+1 provee un equipo, modulo, trayectoria o sistema adicional al minimo requerimiento para
satisfacer los requisitos base. La falla o mantenimiento de un solo equipo, modulo, trayectoria o sistema no
interrumpira la operación.
N+2 Redundancia
2N Redundancia
La redundancia 2N provee dos unidades, modulos, trayectorias o sistemas para cada uno de los requisitos base. La
falla o manteniemiento de una unidad, modulo, trayectoria o sistema no interrumpira las operaciones.
2(N+1) Redundancia
La redundancia 2(N+1) provee dos unidades, modulos, trayectoras o sistemas (N+1). Aun cuando exista una falla o
un manteniemiento de una unidad, modulo, trayectoria o sistema, se tiene alguna redundancia asi que las
operaciones no se ven interrumpidas.

Tier I: Basic Site Infrastructure
a)
A Tier I basic data center has non-redundant capacity
components and a single, non-redundant distribution path
serving the critical environment. Tier I infrastructure includes: a
dedicated space for IT Systems; a UPS to filter power spikes, sags,
and momentary outages; dedicated cooling equipment; and on-site
power production (e.g., engine generator, fuel cell) to protect IT
functions from extended power outages.
b)
Twelve hours of on-site fuel storage for on-site power production
(e.g., engine generator, fuel cell).

Tier III: Concurrently Maintainable Site Infrastructure
The fundamental requirement
A Concurrently Maintainable data center has redundant capacity
components and multiple independent distribution paths serving
the critical environment. For the electrical power backbone and
mechanical distribution path, only one distribution path is required
to serve the critical environment at any time.

All IT equipment is dual powered and installed properly to be

Tier IV: Fault Tolerant Site Infrastructure
a)
b)
A Fault Tolerant data center has multiple, independent, physically
isolated systems that provide redundant capacity components
and multiple, independent, diverse, active distribution paths
simultaneously serving the critical environment. The redundant
capacity components and diverse distribution paths shall be
configured such that ‘N’ capacity is providing power and cooling to the
critical environment after any infrastructure failure.
All IT equipment is dual powered with a Fault Tolerant power
design internal to the unit and installed properly to be compatible with
the topology of the site’s architecture. Transfer devices, such as pointof-use switches, must be incorporated for critical environment that

c)
d)
Complementary systems and distribution paths must be
physically isolated from one another (Compartmentalized) to
prevent any single event from simultaneously impacting both systems
or distribution paths.
Continuous Cooling is required. Continuous Cooling provides a
stable environment for all critical spaces within the ASHRAE
maximum temperature change for IT equipment as defined in
Thermal Guidelines for Data Processing Environments, Third Edition.
Additionally, the Continuous Cooling duration should be such that it
provides cooling until the mechanical system is providing rated
cooling at the extreme ambient conditions.

DCD - CALA
On-site power production systems (e.g., engine generator, fuel cell)
are considered the primary power source for the data center. The
local power utility is an economic alternative. Disruptions to the utility
power are not considered a failure, but rather an expected operational
condition for which the site must be prepared. Accordingly, on-site power
production systems must automatically start and assume load upon loss of
utility. In addition, all critical equipment not backed up by UPS power must
autonomously restart after the power is restored. Although engine
generators are only one solution for onsite power production, the nuances
of the ratings dictate additional commentary to describe the specific
requirements that must be met when using an engine-generator system
for on-site power production.
