【文件原名】： Telecommunications Infrastructure Standard for Data Centers
【摘要或目录】：The purpose of this Standard is to provide requirements and guidelines for the design and
installation of a data center or computer room. It is intended for use by designers who need a
comprehensive understanding of the data center design including the facility planning, the cabling
system, and the network design. The standard will enable the data center design to be
considered early in the building development process, contributing to the architectural
considerations, by providing information that cuts across the multidisciplinary design efforts;
promoting cooperation in the design and construction phases. Adequate planning during building
construction or renovation is significantly less expensive and less disruptive than after the facility
is operational. Data centers in particular can benefit from infrastructure that is planned in advance
to support growth and changes in the computer systems that the data centers are designed to
support.
This document in particular, presents an infrastructure topology for accessing and connecting the
respective elements in the various cabling system configurations currently found in the data
center environment. In order to determine the performance requirements of a generic cabling
system, various telecommunications services and applications were considered. In addition, this
document addresses the floor layout topology related to achieving the proper balance between
security, rack density and manageability.
The standard specifies a generic telecommunications cabling system for the data center and
related facilities whose primary function is information technology. Such application spaces may
be dedicated to a private company or institution, or occupied by one or more service providers to
host Internet connections, and data storage devices.
Data centers support a wide range of transmission protocols. Some of these transmission
protocols impose distance restrictions that are shorter than those imposed by this Standard.
When applying specific transmission protocols, consult standards, regulations, equipment
vendors, and system service suppliers for applicability, limitations, and ancillary requirements.
Consider consolidating standardized and proprietary cabling into a single structured cabling
system.
