Redundancy is a critical factor when choosing a Data Center provider because it directly affects the level of systems availability. There are several power components in a Data Center, and every one of them is a point of failure, which can incur significant financial and data losses for your company. Get to know more about levels of redundancy and choose what's best for your business.

1. Understanding Power Redundancy
Levels N, N+1, 2N

2. What is Power Redundancy?
MOST COMMON POWER REDUNDANCY LEVELS
The principle of redundancy in automated
systems is providing a switchover of
functionality to a standby or backup
component in case of failure of a primary
component.
The switching is supposed to occur
automatically, and an operator should not
be required for the switchover.
There are several types of redundancy - N,
N+1, 2N, 2(N+1), 3N/2 - that typically refer
to the number of power and cooling
components that comprise the data
center infrastructure systems.

3. MOST COMMON POWER REDUNDANCY LEVELS
The “N” Level: Only base load requirements.
An N configuration system is essentially
composed of a series of single points of
failure. It meets base load requirements
with no redundancy.
The failure of any component will cause
an outage. Thus mission critical
application would suffer in this setting.
This level of redundancy describes a
Tier 1 type of facility, and it is not
recommended if your operation can't
stand disruptions.

4. MOST COMMON POWER REDUNDANCY LEVELS
N+1 redundancy: What you should know.
The “N” refers to the number of
components necessary to run your
system.
“+1” means that there is one additional
unit/module/path more than the base
requirement (N). This configuration is also
known as Parallel Redundant.
Failure on a single unit will not disrupt
operations. However, it is not considered
a fully redundant system and still has a
single point of failure. This setting runs on
shared feeds at one or more points rather
than two completely separate feeds.

5. MOST COMMON POWER REDUNDANCY LEVELS
2N Level: Go entirely redundant.
A 2N infrastructure contains double the
amount of equipment needed that run
separately with no single points of
failure.
Two complete units/modules/paths for
every one required for operation equates
to fully redundant.
Failure of one entire system will not
disrupt operations or affect performance
for dual-corded loads.
Avoid risks and go for 2N power
redundancy

Power Components In A Data Center
There are several power components in a Data Center and every one of them is a point
of failure, which can incur significant financial and data losses for your company.
There’s a quick list of the components:
● Main Power Source of the facility
● Power Backup Generator
● Uninterruptible Power Supply, commonly known as UPS
● Power Distribution Unit or PDU
● Rack Power Distribution Unit
● Built-in power supply of the equipment (server, router, switch, etc.)
A Data Center must increase the reliability of these critical power components by
implementing redundancy, to provide a high availability environment for your assets.
At McAllen Data Center, we provide 2N-redundant colocation services relying on Vertiv,
former Emerson, which is the best power equipment in the industry. Even though it
costs more, we do whatever it takes for our clients’ peace of mind.

7. McAllen Data Center offers a top-notch
infrastructure for carriers and
enterprises, so that they can focus on
their core business without worries.
We are proud to have implemented the
latest technology in standby power
backup. Our dual generators are fueled
by Natural Gas and were set up following
best practices for 2N redundancy.
