If the cost saving weren't enough, there are also qualitative advantages to right-sizing with modular equipment. Scalable solutions normally come in a "plug and play" set-up which will eliminate the need for hot work. Also, special site preparation, such as raised floors, would be reduced. Of course the system would still be capable of operating in N, N+1, or 2N configurations without modification and installation work such as wiring, drilling, and cutting would be greatly reduced. The need for special permitting or regulatory procedures that are sometimes needed in order to increase capacity would also be reduced. Finally, the maintenance cost of the modular power system would be the same or less than the cost of the traditional centralised system.
With the immense potential that right-sizing has in improving data centre energy efficiency and reducing electrical consumption, it is an important aspect that organisations need to focus on in order to drive cost savings, enhance competitiveness and mitigate impacts that their data centres have on the environment.
