Hatteland Computer Centre Vats is built 12 metres inside the mountain and has, as one of the most secure computer centres in Europe, attained the “EMP (see footnote) protected 80dB pulse suppression” certification.
The mountain hall has two separate systems originating in different locations and via different routes inside the mountain. There are also two physically separate systems, from two different locations, for the cubicles. If there is a need for greater capacity, then we can at least double the capacity without the need to make any physical changes to the structure of the building.
We have Masterguard battery reserves, which when fully charged provide us with 200kVA for two hours.
Our diesel aggregate, which is automatic, will start after 20 seconds and delivers 500kVA.
It has a diesel reserve of 4,000 litres. If necessary both of the diesel aggregates can be run in series.
The entire mountain hall is set up with two separate cooling systems (the main system and a back-up). One cooling system is based on seawater heat exchange and has a capacity of 500kW. The air based cooling system has a capacity of 300kW.
Per cubicle: The cubicles are cooled by two systems which are independent of each other. The cooling capacity is 30kW for both the main system and the back-up solution. The entire system is, of course, connected to our operations centre and is monitored 24 hours a day, 365 days a year.
The Hatteland Group has two fibre cables within the mountain hall and these enter via different routes. There is automatic redundancy of lines from our main supplier. Our operations centre continuously monitors all of our lines.
The mountain hall is protected against fire and intruders with state-of-the-art warning and monitoring systems. The entire system is divided up and protected by different access zones, which are kept locked and are controlled with the aid of an access control system. These systems are also connected to our alarm centre that is notified by all alarms that the system has to pick up.
The system makes use of detectors that are triggered with a reduced visibility of 0.3%, at a distance of one metre. Every detector is addressable, which means that if an alarm goes off we will know immediately which detector it is.
The system is based on non-contact cards. Each card reader is connected up to a centre that provides us with continuous monitoring of entrance traffic and an alarm sounds if unauthorised entrance is attempted. Four safety zones, where separate authorisation is required to gain access to each zone, protect our mountain hall.
EMP
An electromagnetic pulse (EMP) is a momentary, intensive electromagnetic discharge, which in some cases can cause damage to electronic components. A distinction is normally made between electromagnetic pulses caused by nuclear weapons (NEMP) or conventional weapons and electromagnetic pulses caused by natural phenomena such as lightning electromagnetic pulse (LEMP).
