| Summary: | The maximum dimensional sizes of the computer room as a key architectural component of a data center have been justified, organized within various organizations of the construction industry. Mathematical models of the computer room have been introduced based on statistics of implemented projects, taking into account the presence of a central cross-connect and a ramp, as well as the routing of wired communication lines implemented within it. The criterion of the small size of the computer room as a structure allowing the organization of information exchange according to the spine-leaf scheme over twisted pair cables of the ISO/IEC 11801-1:2017 standard has been introduced. Assuming the use of a parallel transmission scheme involving Shannon's theorem and IEEE recommendations regarding operational margins, the maximum length of the line statistically associated with the dimensions of the computer room has been determined. An estimation of the maximum number of pizza-box type servers and standard 19-inch racks with heights of 42 units for their placement has been provided. The allocated power has been determined, taking into account the achieved level of technology, which is crucial from the perspective of designing the air conditioning and power supply systems.
