Hamburg London Berlin Frankfurt/Main Munich Zurich e-shelter Datacentre location e-shelter Datacentre location planned Currently e-shelter operates more than 85,000 sqm of data center space, three additional locations are under development Overview locations Data Center Campus Frankfurt • 60,000 sqm area • 24/7 Service & Control centre • Headquarters Data Center Campus Berlin • 13,000 sqm area Data Center Campus Zurich • 7,000 sqm area in operation, additional 6,000 planned Colocation Centers • Frankfurt (1,900 sqm) • Munich (1,960 sqm) • Hamburg (1,230 sqm) New locations • London • Munich II • Frankfurt III High Density - High Efficiency - High Temperature in the Data CenterEfficiency trap in the Data Center

7. e-shelter planning and design implements highest standards in energy efficiency and latest developments in technical progress Energy efficiency and sustainability Research & Development In order to develop best-practice approaches for energy efficient operation of data centers e-shelter is actively engaged in different workshops and organisations e.g. “the green grid“ and “Uptime Institute.” e-shelter works with large suppliers of cooling technology to explore and testnew cooling techniques, and has developed a sophisticated measuring system to continuously monitor energy utilization (e.g. cooling requirements in different zones). Operational excellence e-shelter designs and operates its data centers to be highly efficient and applies state-of-the-art technology to achieve an optimal utilization of energy. Hereby e-shelter is able to achieve highly competitive power utilization efficiency factors for its data centers (PUE factor).

13. Security

14. Structural, technical and organizational separation of the security zones Security Systems • The security concept includes having all safety-sensitive areas situated in the core of the building to the extent where this is feasible so that the security zones beyond the core serve as buffers. • All security zones are structurally, technically and organizationally separated from one another • All security zones are monitored by way of synchronized technical safety measures • This way it is ensured that the cumulative safety function for creating the necessary penetration resistance/ resistant time value Security Command and Control centre (SCC) 7 Carrier rooms 6 Datacentre areas 5 Technical areas 4 Circulation area for tenants Circulation area building(s) Circulation area Datacentre site 3 2 1 High Density - High Efficiency - High Temperature in the Data CenterEfficiency trap in the Data Center

15. Power and Cooling Systems

16. The redundant power supply guarantees maximum availabilityPower supply • Power is distributed on an A & B feed up to the rack • The critical components of the power supply are designed in an 2N+1 configuration • State-of-the-art static UPS systems with a high degree of scalability and reliability incl. isolating transformers • On-site back-up power (diesel generators) in an N+2 configuration • 72h diesel-fuel storage on site.
