Iron Mountain, the US-based information management systems company, has agreed to pay €205m for EvoSwitch of Haarlem, which operates at two major data centre locations in the Netherlands.

The deal gives Iron Mountain control of 11 megawatt of data centre capacity close to Amsterdam, and expansion capacity of a further 23 megawatt, Iron Mountain said in a statement. The deal takes the US company’s total data centre capacity to 238 megawatts.

EvoSwitch’s operations provide support to more than 50 telecommunications and connectivity providers. These include the Amsterdam Internet Exchange AMS-IX, which is crucial for the internet connections for many multinationals.
