iDC Air-42 provides an easy way to build up a datacenter with regular room partitions and a general cooling system. It is designed for deployment scales ranging from 1 to 100 racks. It complies with a datacenter requirement as it consists of fire suppression, a UPS, a monitoring and control system. It provides much better protection than a traditional datacenter in the multi-floor environments. Any water leakage risk from upper floor can be eliminated. It significantly reduces the fixed capex compared with a traditional datacenter.
