Why early planning of data cabling is so important
As the bandwidths required by new active technology in today's data centers grow, so do the demands on the passive infrastructure. Data cabling should therefore be planned as early as possible, preferably together with power supply and air conditioning. A well conceived and effective cabling should harmonize the optimization of transmission lengths and attenuation budgets with a clear (and therefore flexible) structure. The selection of an individual cabling concept suitable for the respective data center must be in line with the standards EN 50173-5, EN 50174-1-2 and, as soon as available, EN 50600-2-4.
Terms such as energy efficiency, cooling optimization, adapted consolidation, intelligent monitoring and physical security concepts are also covered by us. Based on the individual parameter requirements, we work with our customers to develop a goal that can be achieved through modular system solutions, because the overall efficiency of IT is decisive for any data center planning. A scalable orientation is just as relevant as well as coordinated energy, cooling and security components according to the building structure and its geometry. The intention of data center planning is to optimize the interfaces between the various parameters such as IT infrastructure, security technology, fire alarm technology and access control by means of modular structures. In this way, IT infrastructures can be flexibly and cost-effectively adapted to future developments. "IT on demand" is the key to this. This means that we plan with a deployment in which the systems are implemented according to demand and can be expanded at any time through a modular structure.
Redundant planning needed
Redundant planning is essential for effective project realization with regard to optimized DC infrastructures and performance capacities. It can avoid unnecessary energy consumption and thus increased operating costs. Redundancies in power and cooling supply are just as important in modern data centers as double supply and constant system maintenance. The recommended room temperature in a data center, for example, is between 22° and 25°C, with a relative humidity of 30 to 50%. The operating temperature must therefore be kept constant in order to avoid impairing the IT components.
Datacenter inventory analysis and quality assurance
Updates in data transfer rates must also be taken into account in individual planning: For example, to ensure that the existing cabling is suitable for a pending bandwidth update - such as from 16 to 32 Gbit Fibre Channel - we offer a proactive check of the passive IT infrastructure using OTDR (optical time domain reflectometry) or on the basis of a BERT test (bit error test). In addition, we analyze the existing cabling for contamination using video microscopy.
What exactly is OTDR?
An Optical Time Domain Reflectometer (OTDR) is a fiber optic instrument for characterization, troubleshooting and maintenance of optical telecommunication networks. OTDR tests are performed by transmitting and analyzing pulsed laser light passing through an optical fiber. The measurement should be unidirectional as the light is used at the end of a fiber optic link.
Third-party assessment and monitoring
Finally, external suppliers and third-party vendors are often an integral part of the data center environment. Should the planner not be able to be on site or in his data center to check or approve the services of the provider, we are happy to take over this part as a neutral authority for the customer. Within the framework of Quality Assurance Management, we ensure that the quality standards of the third-party provider are adhered to at all times.
