Our Enschede datacenter is a ISO27001 and NEN7510 certified datacenter designed according to the Tier 3 specifications. The Tier 3 specification describes how the minimal expected availability of 99.982% can be guaranteed by use of redundant components througout the datacenter (Power, Cooling and Internet).
InterDC can accomodate a total of 60 racks and thus can house over 1800 servers.

A schematic view of the Enschede datacenter:

Datafloor

The Enschede datacenter consists of approximately 1,290 square foot for a total of 60 racks and uses a raised floor system for optimal cooling and cable management. With a raised floor cold air is provided through the ventilations panels placed on the datafloor surface. The server racks are placed in a hot and cold corridor for the most optimal cooling performance.
For the near future we can expand our datafloor with a second room of 200m2 or 2,152 sq feet space.

Security

The Enschede datacenter is secured by multiple HD cameras. The cameras are equipped with motion sensors which allows them to detect possible intrusions in a darkend environment. Physical access to the datafloor is regulated via access cards and unique pin numbers. In the event that someone loses his / her access cards, no access can be gained without the unique pin number.
Every camera, motion detector, light and doors are managed via our BMS (Building Management Software). In addition to security our systems monitors data from temperature, power usage and fire detection sensors.

(Emergency) Power

The electrical system is equipped with a redundant UPS system from Eaton in combination with a Lovol Marelli back-up generator. Thereby every rack is provided with two redundant 16 Amp power feeds (No-break). Additional power feeds can be provided.

Firedetection

The datafloor is protected via the VESDA (Very Early Smoke Detection Apparatus) laser detectors. VESDA is capable to detect a fire in the very early stages. The moment the VESDA system detects a possible fire it will send out an alarm via our BMS (Building management system). Thereby hanging in the hallway leading to the datafloor are multiple CO₂ fire extinguishers.

Cooling

The Enschede datacenter uses free air cooling for most of the year, which means that outside air is being used to cool the servers. This method of cooling is possible because the temperature, in the Netherlands, is below the 20 degrees celsius for about 80% of the year. The remaining 20% of the year uses the traditional systems from Trane and Uniflair.

The average maintained temperature in the datacenter is ± 24 degrees Celsius.

Other facilities

InterDC also provides a meeting room and a canteen for lunch breaks.
