Controlling electromagnetic radiation in a data center

1. An apparatus comprising:

a computer processor,

a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

receiving a specification of preferred electromagnetic (‘EM’) radiation characteristics for a data center, the data center comprising a plurality of EM sections, each EM section comprising an electrically conductive metal; and

setting a state of each EM section in accordance with the specification, wherein the state of each EM section comprises one of: an absorption state in which the EM section absorbs EM radiation or a reflection state in which the EM section reflects EM radiation wherein setting a state of each EM section in accordance with the specification further comprises:

setting at least one EM section to reflect EM radiation including electrically decoupling the EM section to a ground reference voltage; and

setting at least one other EM section to absorb EM radiation including electrically coupling the EM section to a ground reference voltage.

2. The apparatus of claim 1 , further comprising computer program instructions capable of repositioning one of the EM sections set in the reflection state including controlling a direction of EM radiation reflected by the EM section.

3. The apparatus of claim 1 , wherein:

the data center further comprises one or more walls, a ceiling, and a floor; and

each wall comprises one or more EM sections, the ceiling comprises one or more EM sections, and the floor comprises one or more EM sections.

4. The apparatus of claim 1 , wherein at least a portion of the EM radiation controlled in the data center comprises wireless data communications.

5. A computer program product comprising:

a non-transitory computer readable medium and computer program instructions stored on the non-transitory computer readable medium that, when executed, cause a computer to carry out the steps of:

receiving a specification of preferred electromagnetic (‘EM’) radiation characteristics for a data center, the data center comprising a plurality of EM sections, each EM section comprising an electrically conductive metal; and

setting a state of each EM section in accordance with the specification, wherein the state of each EM section comprises one of: an absorption state in which the EM section absorbs EM radiation or a reflection state in which the EM section reflects EM radiation wherein setting a state of each EM section in accordance with the specification further comprises:

setting at least one EM section to reflect EM radiation including electrically decoupling the EM section to a ground reference voltage; and

setting at least one other EM section to absorb EM radiation including electrically coupling the EM section to a ground reference voltage.

6. The computer program product of claim 5 , further comprising computer program instructions that, when executed, cause the computer to carry out the step of repositioning one of the EM sections set in the reflection state including controlling a direction of EM radiation reflected by the EM section.

7. The computer program product of claim 5 , wherein:

the data center further comprises one or more walls, a ceiling, and a floor; and

each wall comprises one or more EM sections, the ceiling comprises one or more EM sections, and the floor comprises one or more EM sections.

8. The computer program product of claim 5 , wherein at least a portion of the EM radiation controlled in the data center comprises wireless data communications.
