Key Challenges & Drivers Impacting the Data Centre Industry Reliability/Uptime SLA s Contamination Energy Costs Carbon Emissions Modularity
Uptime & Reliability Tier 1: Tier 2: Tier 3: Tier 4: Non-redundant capacity components (single uplink and servers). Tier 1 + Redundant capacity components. Tier 1 + Tier 2 + Dual-powered equipment and multiple uplinks. Tier 1 + Tier 2 + Tier 3 + all components are fully fault-tolerant including uplinks, storage, chillers, HVAC systems, servers etc. Everything is dual-powered. The levels also describes the guaranteed availability of data from the hardware at a location: Tier 1: 99.671% availability. Tier 2: 99.741% availability. Tier 3: Tier 4: 99.982% availability. RELIABILITY is THE Critical Success Factor 99.995% availability.

Legionella Risk Analysis The Risk Assessment of the OASIS unit confirms that the risks of causing growth and spread of Legionella bacteria are negligible. If the temperature is below 25 C, no risk of occurrence of Legionella in the system, which is the case most of the time. In the operating conditions for water above 25 C, the system is designed so that water flows continuously in the circuit so that there is no stagnation of water and no risk of emergence of bacteria. The Oasis IEC has an automatic emptying system that starts if installation is at standstill for agreed hours. Therefore no risk of proliferation of legionella in the water recovery pan.
