 - Energy usage per rack or server: The energy consumption per unit of computing resource (e.g., per rack, per server) is tracked to optimize energy use in the datacenter. 
 - Cooling efficiency: Temperature differential: Measures the difference between intake and exhaust temperatures in cooling systems. 
 - Cooling system efficiency (COP - coefficient of performance): Measures the effectiveness of the cooling system, ideally higher COP means better energy efficiency. 
-- Cooling usage effectiveness (CUE): Similar to PUE, CUE measures how efficiently cooling is used in the datacenter. It is calculated by dividing the total energy used for cooling by the energy used by the IT equipment.

 | **Fault tolerance**: Fault tolerance ensures that a system can continue operating even if a specific component fails. | • RAID (Redundant Array of Independent Disks) for data storage. <br />• Load balancing across multiple servers to avoid overloading. |

Cold datacenter sites are essentially empty facilities with power and cooling infrastructure but no IT equipment. They require procurement and installation of all necessary hardware, software, and data backups during a disaster. If the primary datacenter were to fail, both warm and cold sites serve as backup locations for critical operations, which helps to minimize downtime and ensure continuity of datacenter operations. |
