UPSs and diesel generators are two backup systems which are kept by web hosting providers inside their data centers in the event that there are interruptions in the primary power source or the current is unstable and unable to sustain the proper operation of the servers based inside the facility. UPS stands for Uninterruptible Power Supply or Uninterruptible Power Source and it's a powerful battery which works non-stop. It is connected to both the electrical power network and the web servers at all times, so when the power stops, the UPS is already functioning, which prevents the web servers from going down even for a second. The diesel generator is literally an engine that can deliver the required power to keep the servers working for a longer period of time. In case there is an outage, the UPS provides the necessary time for the diesel generator to start and then to take over until the main power source is restored.
UPS & Diesel Back-up Generator in Semi-dedicated Servers
The semi-dedicated server accounts that we provide you with are created within a state-of-the-art data center in downtown Chicago and its power backup system is among the reasons why we can afford to guarantee a 99.9% uptime for both the machines that are part of our sophisticated hosting platform and the network which manages all the traffic to and from them. An individual UPS system is connected to every machine to keep it online until numerous generators kick in. The latter are potent enough to provide electricity for the entire data center for many hours without having to restrict the power consumption or the productivity of any web server or network device, so even when there is an interruption, all of the websites hosted on our platform will still be accessible with no disruptions and will function at top speed.
