Hot or Cold Aisle Containment
CAC (Cold Aisle Containment Systems) has doors at the end of the aisles and partitions on the ceiling that act as a physical barrier to contain the airflow.
HACS (Hot Aisle Containment System) encloses the hot aisle to accumulate the IT equipment's hot exhaust air, allowing the rest of the data center to become a large cold air containment facility.
Africa Data Centres require a minimum 8 kW rack densities for this option to be offered. Containment can either be CAC or HACS dependent on the site conditions and can be retrofitted to existing rack hardware or bundled with new racks.
