One of the difficulties that network systems and equipment sometimes face is that network devices only have a single power server. Although sometimes this type of power supply works well in stable network applications, it does not work well in system applications used in finance, administration or transportation that need power redundancy in order to guarantee dependability and persistent accessibility.
Most computer networks provide the option of redundant power servers. They do that so in case one power server fails, another power server can be able to take over the load.
What is a redundant power server?
A redundant power server is a server that has two or more power supply units in it. Each of these units has the capability to provide power to the entire computer. Only one power supply runs at a single time. It is usually used in high-end computers. Redundant power servers let uninterrupted system operations continue in an incident of malfunction of one or more power supplies in the network. If one of these power supplies fails, another power supply will take over to power the whole computer. The shift between the power supplies is smooth so that it would not interrupt the normal functionality of the computer.
Who should use a redundant power server?
Having a redundant power server can increase your server’s reliability. It is more suitable to high-end computers which require a guaranteed power supply no matter what happens to the system. Not every user is encouraged to have a redundant power server. Besides its specific functions that can only be useful to high-end computers, it is also more costly than other power servers. The following items are those that are more encouraged to use a redundant power server:
- Business and online applications where network disruption or stoppage will greatly affect the customer’s access to data, information and other applications.
- Users who use servers where a technical expert might be hours or days away from assisting in case of device failure.
- Very critical applications where power supplies cannot fail. An example for this would be for scientific applications or engineering researches that are not error tolerant. In these cases, any power failure could compromise the whole project or research.
- It is required for systems with a high mark of fault tolerance.
What are the benefits of a redundant power server?
A redundant power server can give you the following benefits:
- It is important for servers to reduce the chance of an absolute computer breakdown or failure.
- In cases of network shutdown, it is essential that your network can quickly recover. This is important especially for those who are running an online business. Having a redundant power server can prevent a total network shutdown.
- It guarantees that important network capabilities are always accessible whenever the customer needs it.
- It lets you easily handle various uninterrupted power supply issues.
- It improves the reliability of your power server.
- It gives more PC security.
Are there any disadvantages in using a redundant power server?
While a redundant power server provides many benefits, there are also some weaknesses in using it. Redundant power servers sometimes provide less reliability, instead of more, due to its complicated system which is more disposed to some technical issues. It may also lead to increased pressure on the network that can result to a faster network speed yet making it less safe.
Sometimes, having a redundant power server may not reduce the overall chance of network failure. Power servers and supplies can fail in a couple of ways. There can be problems caused by outside factors and not just the power supply itself. In such cases, redundant power servers can no longer help. It can even cause harm by keeping the device running while a sudden shutdown might be better to cover the loss.
