The Importance Of The Redundant Power Backup For Data Centers

The Importance Of The Redundant Power Backup For Data Centers

The data center is referring to the amount of available power backup. When a data center provider shares its facilities redundancy. If utility failures occur due to severe weather, equipment failure or power line damage, data centers with more redundant power will be better equipped to avoid costly periods of downtime. With the help of this blog, you will understand. “Power Backup For Data Centers”.

The redundant power is the access the essential for the data centers. The important of the redundant backup power just like many data centers of the backup power system that is desirable.

Most of the data centers have an architecture in place to cut the risk of downtime. There are different levels of redundancy.

Why Redundant Power Backup For Data Centers is Valuable.

When we architecting and running a data center redundancy is a core concept. Backup capabilities for the critical data center are more essential to the smooth management of a data center. If a redundant primary service. Electrical service, function, feature or telecommunication line goes down, the backup power can easily pick up the slack and allowing maximum uptime until the failing item is fixed.

No need to forget about redundancy. If you are running in a managed service provider environment or running critical services in the cloud. You need to understand exactly what redundant features are provided in your hosting contract, and also get the service list in writing.

In this article, we will discuss the importance of redundant backup for data centers, while offering several solutions to improve your businesses.

Planning For The Future

You must attempt to anticipate future growth and needs to create the right system for your data center. The power backup for data centers, solutions are constantly evolving.  So, while you may have a power backup plan that worked well in years past, it may not align with your business growth strategy.

That is very important that an experienced technician perform regular audits of your backup system. The basic power system of a data center includes the backup generator, uninterruptible power supply, internal power supply, power distribution unit and much more. To the complete support for the data center and all its components with no single points of failure, one fully redundant power supply will have an adequate amount of power supply.

The Generator Must be Synced With UPS

You need to ensure, that the power generators are properly synchronized with the UPS system. So there is no interruption of service when transferring to generator power.

While there is power backup for data centers with low loads that can rely on an uninterrupted power service to handle power for a short outage. But those systems are not able to handle the growing power emergency power needs of today’s system. So, in addition to UPS, the most data center should trust a backup generator in the event that local utility electricity fails.

One of the best decisions, if you will invest in a used generator to trust as a backup in case the primary generator fails. Because a generator with a sufficient fuel capacity may not be enough to provide truly redundant power.

Cooling Requirements

Also, the provision of back-up power for protected loads in case of an outage brings with it the accompanying cooling requirements for the operating equipment, which if not satisfied can cause permanent damage to the systems on account of overheating.

Prevention Work For a Long Way

You need to develop a disaster plan in order to safeguard your data center against power failure. But also you need to focus on preventing outage before it is too late. Power systems that are working in the emergency condition are quite beneficial in the event of a disaster. But for staying ahead of the curve prevention is the best strategy. This will help you to keep your data center online so you can perform your necessary business functions. Power monitoring PDUs (Power Distribution Units) can help data centers track power usage and environmental factors (i.e. temperature & humidity). With the help of a power monitoring PDU, you have access to information about the status of your server rooms, allowing you to take steps to ensure outages don’t occur.

Most data centers have systems in place to cut off the risk of downtime. These systems have categorized into N+1, 2N, and 2(N+1).

Here we will discuss the various systems to cut off the risk of downtime. But before discussing these topics we need to understand,

What is N?

The presentation of N equals to the amount of capacity required to power or cool the data center facility at full IT load. Arrangement of N means, the facility was designed only to account for the facility at full load and zero redundancy has been added. The mission-critical application would suffer if the facility is at load time and there is a component failure or required maintenance. N is the same as non-redundant. Now we will discuss different categories of N.

What is N+1?

A simple way to see N+1 is if we are ordering the burger for office breakfast. There are 20 people working in our office and we decide to order more orders just in case. We will count the correct no. of bags whereas the extra burger is +1 we will be shown working with N+1 or that will be 21 burgers.

Redundancy is our IT environments best friend. N equals the amount of capacity required to the power, backup or cools a facility at full IT load.

What is 2N?

If you want to order bagels with a 2N mindset, you would order 20 from one shop and 20 from the other one. The 2N is standing with double, or two times. Here N is the number of bagels you want. If one shop does not deliver your order, you will still have an option from the other one.

Same for the data center. They have 2N redundancy, which means you have twice the option of equipment needed with no single point of failure. 2N system will maintain without losing power to the subsequent system when an extended power outage occurs.

What is 2(N+1)?

To the data center architecture 2(N+1) stands as fully redundant. So if there is two UPS requirement, there would be two independent UPS present for resiliency. In this architecture, one can take down an entire leg with zero interruption to the critical IT load.

There is no requirement to do the same make and model, or even the same capacity. Redundant components with different capacities are able to increase the load management challenge. We can say (2N+1) is a facility that is running at half load or an N or N+1 design. Because presently at half the load design is not make it 2N.


When looking at the established data center, there are several things that we may be looking for. Power, security, and networking. These are big things that should be on the list, but we also want to look at redundancy. The redundancy means that are backup components to make sure power backup for data centers. If that is a Networking card, power supply, or Ethernet cable fails, our business will not suffer.

Because If the primary source fails then the has to be handled. Another term used to describe redundancy is high availability, because of the increased availability of our resources. Through these measures deployed internally at Vault Networks. We are able to achieve our 99.999 percent uptime service level agreement (SLA) when these measures.
