This is a case study of how the Dutch Police Force consolidated 26 smaller data centers into seven twin-center data centers and one high-secure data center. This was a six-year project that encompassed 55,000 workstations and approximately 60,000 employees. The discussion covers how they handled consolidation, availability (Tier I–IV), security, EU standards, disaster/recovery planning and more.

TIA – 942 Data Centre Location Recommendations:
• The building should not be in the flight path of any nearby airports.
• The building should be no closer than 0.8 km (½ mile) from a railroad or major
interstate highway to minimize risk of chemical spills.
• The building should not be within 0.4 km (¼ mile) of an airport, research lab,
chemical plant, landfill, river, coastline, or dam.
• The building should not be within 0.8 km (½ mile) of a military base.
• The building should not be within 1.6 km (1 mile) of nuclear, munitions, or
• The building should not be located adjacent to a foreign embassy.
• The building should not be located in high crime areas.
• EMC risks must be minimised by locating away from radar transmitters and
mobile ‘phone masts.
• The building should not be located below sea level or flood area’s.
