Tips and tricks to achieve major data centre resilience in a small facility

1. Data Centres in Shared Buildings Barry Shambrook RCDD Tuckers Consultancy Ltd

3. Space example

4. Monthly colocation costs per rack Source: www.mobilepricing.com

5. Monthly TCO per rack

6. Cost and emissions £300 per month 1 Tonne CO 2 /Balloon 2 Balloons per month

7. Carbon Reduction Commitment

8. Lurking Vulnerabilities Latent deficiencies can surface at the worst possible moment

9. How Much Redundancy is Enough?
