This deployment allows the supply and return air paths of IT equipment to be separated, ensuring predictable cooling behaviour and enabling cooling capacity to be right-sized to the heat load. Because of this, NUS is able to overcome the issue of unpredictable cooling performance caused by deployment of high density loads in its facility and also able to experience maximum cooling predictability, capacity and efficiency.
More importantly, with the hybrid approach, the institution is able to future-proof its data centre, ensuring maximum system flexibility and scalability to rapidly meet end-users or business growth demands.
As we move into 2013 and beyond, we expect to see many more data centres utilising a mixture of the three cooling methods as they witness their peers reap the myriad benefits of the hybrid approach - flexibility, predictability, scalability, reduced electrical power consumption, reduced TCO, and optimum availability that next generation data centres require.
