Technical spotlight: Network 

level N+X redundancy

As business moves from a “bricks and mortar” model to “clicks

and mortar,” the need for system availability at all levels of

enterprise is rising exponentially. From servers to routers to

telecommunication installations, the interdependence of the

technological components of the wired world can make systems

vulnerable to downtime. Many precautions and preventive

measures are taken when designing the network, including power

protection.
In this shifting world, however, it’s becoming more evident that

simple power protection isn’t enough. A new level of reliability

is needed, one with redundancy, and thereby system availability.

Today users can opt for an even greater degree of redundancy,

with N+1, N+2, N+3, etc. However, this level of redundancy can

quickly become cost prohibitive if the user is creating redundant

systems with a single-module UPS. The 9170+ overcomes this

potential obstacle with its modular design. Redundancy comes

from the 3 kVA power modules plugged into the system. For

example, if you have a 9 kVA solution, and are looking for N+2

redundancy, you only need a 15 kVA UPS (five power modules)

with the 9170+, instead of 18 kVA. That’s because the five

UPS modules run in parallel within the system, giving you N+2

redundancy, without the additional cost and space requirements.
The 9170+ eliminates a system-level single point-of-failure.

Because both the logic and power are housed in the module and

not in the enclosure, there is a redundancy for the entire UPS.

This is a critical distinction when looking for multiple levels of

redundancy in the UPS, as there is inherent vulnerability in a UPS

that limits redundancy in any part of the system.

Sample configuration

With a variety cabinet sizes and a user-friendly design you can

configure the scalable and redundant 9170+ with 3 kVA power

modules and battery modules to grow with your requirements.
