Our Infrastructure
Safe and redundant data centres
Combell has several spaces available in different data centres in Belgium. All those data centres are equipped with: UPS (Uninterruptible Power Supply), air conditioning, fire detection, temperature control and other security systems. Our own network infrastructure is redundant, which concretely means that all systems have been installed in duplicate. So, in the event that one system goes down, the other will take over.
Guaranteed power supply
Each server is fed by two power circuits (A + B). In doing this, a power supply redundancy is created for your server. Therefore, in the event that one of the power circuits goes down, your server remains powered by the other one. Moreover, each circuit depends on another public electrical power network. Each circuit is also equipped with UPSs (uninterruptible power supplies) and backup batteries. On top of the redundant power circuits with their backup facilities, there is also a generator that can provide continuous electrical power in case of long-lasting power failures. All backup power supply facilities are tested on a regular basis by a specialized maintenance team that is thus familiar with the entire procedure, so that adequate action can be undertaken when necessary.
Reliable monitoring and checks
Advanced security systems monitor the entire data centre 24/7. Camera surveillance occurs through a closed circuit that registers and archives all activity. Every person who gains access to the data centre must always provide valid identification and is therefore always registered when entering or leaving the premises.
Fire and smoke detection
The data centre is equipped with smoke and fire detection systems. Throughout the data centre, several detectors and gas dispersion systems are present. As soon as smoke is detected at two different locations in the data centre, the alarm sounds and gas is dispersed throughout the data centre. This gas will extract all the oxygen from the air so that the fire gets extinguished. It is forbidden to leave inflammable material lying around in the data centres. The data centres and Combell perform regular checks and reserve the right to immediately remove any inflammable material.
The data centre fully complies with strict fire protection standards.
Active air-conditioning
Air is cooled by high-end climate control systems that have been set up redundantly at several locations throughout the data centre. An efficient cooling is obtained by using the "hot/cold aisle containment" principle, where warm air and cold air are mixed as little as possible.
Network infrastructure
Combell's entire network infrastructure has been designed by certified CISCO engineers. This is how Combell obtained the "CISCO empowered network" label from CISCO Belgium. Routing is entirely redundant.
Network connectivity
Combell uses several providers for its network connectivity. The backbone networks of those providers are fully redundant: all nodes in the backbone are connected to at least two other nodes via circuits that follow separate routes. This adds up to a network that is optimally resistant to disturbances.
Each server is connected to the Internet with a bandwidth of at least 100 Mbit/s for a dedicated server and 10 Mbit/s for a virtual server. However, we only take into account the data traffic that was actually used, unless agreed otherwise. The data traffic can burst to 100 Mbit without any problem. This way, Combell guarantees you the fastest connections.
The data traffic between the servers within Combell's network is free of charge and unlimited.
