Power capacity
The EcoPOD provides 1.2 MW of redundant power and cooling capacity in
closed loop mode. It requires 415V 3Ø power for the IT equipment and 480v
3Ø power for the cooling system. It provides an input power voltage of 240V
3Ø to the racks.
Adaptive Cooling technology
Adaptive Cooling technology allows the EcoPOD to automatically adjust
between one of three operating modes—free air, DX assist, or full DX—
based on IT load, policies, and outside temperature. In free air mode, the
cooling system uses ambient air whenever the temperature is within a range
that meets policy set points. At outside temperatures above or below the
free-air policy set points, the system switches to DX assist mode or full DX
mode. In DX assist mode, a mixture of free air and air from some of the DX
units provides cooling. In full DX mode, the DX units provide all of the
cooling. The EcoPOD delivers a Power Usage Effectiveness (PUE) ratio
ranging from 1.05 (free air mode) to 1.3 (full DX mode).

management both locally and remotely. ECS features include:
•
A single screen STATUS/ALARM page
•
Power, cooling, smoke, and fire-suppression monitoring
•
Dynamic POD fan control
•
Basic and advanced configuration of policy set points for the Adaptive
Cooling modes
•
Customer-programmable alarm levels

Integration with Building Management Systems, via MODbus or TCP/IP
Energy savings
Most traditional data centers have a PUE ratio between 2.0 and 2.4. So for
every watt used by IT devices, these data centers can consume 100% to
140% more energy to house, power, and cool those devices. HP Adaptive
Cooling delivers a PUE that ranges from 1.05 to 1.3, requiring only 5% to
