Redundant Power Servers

In this fast paced world, nothing is predictable. A sickness that just came out of nowhere, sudden weather changes, power outage and more. It also happens on our servers, you’ll never know when an issue will occur and affect the performance of websites that the servers’ hosts. One of the many problems in working with a networking equipment is that they only have one energy port, especially for those older versions. Sometimes, this doesn’t create a problem on network application that doesn’t have heavy workloads, it does though on business network applications for banking, transportation or banking. These kinds of business need constant power supply to make sure that they give good customer service to their consumers.

What is a redundant power supply?

A redundant power supply usually has 2 or more power supply units inside. Each of them has the capability to support a whole computer and only uses one of them, one at a time. Just in case the first PSU shuts down, the second unit will automatically run to keep the computer working. Usually these are found in high end servers, it can also be used on home computers, if you have the budget, because it is pretty pricey.

Power outage presents a big problem on servers because if it does happen, the whole system will be offline, not like disk issues. Because of this scenario, the high end date centers are working and spending so much time and money in building better redundant power supplies, giving importance in back up generators and big UPS or uninterruptible power supply machines. Only one downside to PSU’s is that they are expensive

What are the physical requirements of a redundant power supply?

  •  Fan characteristics – before you choose the fan that your want for your PSU, you should check these features so that you can have the fan that fits your needs
  •  size of the fan
  •  fan bearing type – whether it uses a sleeve or ball bearing
  •  voltage – know how much the fan consumes power
  •  space – the larger the capacity of the fan, the better can give more cooling power
  •  motherboard connectors
  •  drive connectors
  •  weight
  •  form factor and dimension

In order for your power supply units to work properly, you have to put them in a proper place where they can have the proper environmental storage. When it comes to the proper operating temperature range, it should be between 0 – 50, degrees Celsius. Below and above this can result to damage. On humidity range, it should be between 10% – 90% RH or relative humidity. Too much humidity breaks computer equipment.

Quality Specifications

Some specifications of the power supply are not always told about its work, but gives support to its quality all in all. Be attentive when it comes to these specifications, because it will give you a good idea of the power supply’s quality.


Usually, the noise from the power supply units are measured in decibels. The bigger the number, the louder noise the PSU lets out. In earlier PC days, there was only 2 components of the computer that moves continuously, the powers supply fans and hard disk motor. But now, it increased, with new parts such as CPU fans, case cooling fans and more. With more moving components, many users have noticed that their computers are really noisy. So people have been looking for a way to lessen it. When trying to look for a power supply, choose the low noise or silencer feature.


Look for a warranty that has the longest period, this indicates that its makers think that their products are good enough. No company will put a 5 year contract if they know that their product will fail in 1-2 years.
