In the above described standards in the data center architecture SCS and functional subsystems, are the requirements and regulations to cable lines and passive elements. In order to properly design a structured cabling system in data centers should not only be "on hand" these standards, but do not miss out due to 'small details', which can significantly affect the project design, cost and performance data center. At the workshop we will SKS design details in the data center and discuss the finer points, with you may encounter when designing a data center. In the structured cabling system, data center, in contrast to the SCS for commercial buildings, there are several functional areas: the main distribution area (MDA), which sets out the main distribution center and deployed equipment from storage systems and switches with uplink ports, the horizontal distribution area (HDA), which placed horizontal distribution points (HC) and network switches are installed, a hardware distribution area (EDA), hosting servers, switches and patch panels; zonal distribution area (ZDA), which houses a passive connection equipment. We detail the principles of separation of distribution areas and approach to the design of these areas. Designer low-voltage cabling in data centers should carefully consider the siting and installation of telecommunications cabinets in the data center, cable trays used for low-voltage cables. The author will share with seminar workshop participants the knowledge and practical experience, which are used in specific projects of data centers. Designers cabling in data centers are faced with a number of serious problems, such as building cabling system for high-performance computing data center.
