Ensuring that the layout includes ample areas of flexible white space empty spaces within the center that can be easily reallocated to a particular function such as a new equipment area. Ensuring that there is room to expand the data center if it outgrows its current confines. This is typically done by ensuring that the space that surrounds the data center can be easily and inexpensively annexed. Layout In a well-designed data center functional areas are .
