Data Centre/Comms Room Design and Implementation
A Data Centre/Comms Room is a facility used to house computer systems and associated components, such as telecommunications and storage systems. Building a server or computer room requires detailed attention to six main design considerations;

Location - Most designers agree that, where possible, the computer room should not be built where one of its walls is an exterior wall of the building. Avoiding exterior windows and top floors and basements is also important as well as the need to evaluate potential sources of interference that maybe present near the computer room such as radio transmitters and electrical interference from lift rooms or power plants. Other physical design considerations include room size, door sizes, access ramps to get equipment in and out of the room, cabling organisation and security and maintenance access.

Air Conditioning – Maintaining a stable temperature and humidity with tight tolerances is essential to IT system reliability due to the sensitivity of computer equipment to heat, humidity and dust and the need for very high resilience and failover requirements. In most server rooms “close control air conditioning” systems, also known as PAC (Precision Air Conditioning) systems, are installed. These systems control temperature, humidity and particle filtration within tight tolerances 24 hours a day and can be remotely monitored. They can have built-in automatic alerts when conditions within the server room move outside defined tolerances.  Another consideration is the Hot aisle/Cold aisle layout. The goal of a Hot aisle/Cold aisle configuration is to conserve energy and lower cooling costs by managing air flow.

Fire Protection
The fire protection system's main goal should be to detect and alert of fire in the early stages and then bring the fire under control without disrupting the flow of business and without threatening personnel within the premises. Traditionally Halon gas has been used, however many modern computer rooms use combinations of inert gases such as Nitrogen, Argon and CO2. Other solutions include clean chemical agents such as FM200 and also hypoxic air solutions that keep oxygen levels down.

Future Proofing
A crucial part of computer room design is future proofing so that new requirements can be accommodated with minimal effort. As computing requirements grow, so will the power and cooling requirements of the Data Centre/Comms Room. The choice of racks in a server room is usually the prime factor when determining space. Many organization’s use enclosed cabinets or racks to make the most of the space they have.

Depending on the criticality of the IT systems hosted within a server room, removing single points of failure may be of high importance. The level of redundancy is determined by factors such as whether the organisation can tolerate interruption whilst failover systems are activated, or must they be seamless without any business impacts. Other than computer hardware redundancy, the main consideration here is the provisioning of failover power supplies and cooling.

Moves, Adds and Changes
MAC refers to the necessary network administration when users or network components are added to, removed from or change their location in the network. This can be broken down as follows;

Moves – A physical change of the location of the equipment.
Adds – An installation of new equipment.
Changes – Including the change of existing equipment, an upgrade of existing equipment such as a bandwidth upgrade or a modification such as a configuration change to a router or switch.

As departments expand or reduce in size, or as people move from one office to another and you need new voice and data outlets, more bandwidth or modifications to your network we can assist.

All data/voice outlets are individually labelled on each socket, transition point, back box and patch panel with a coded permanent label.  A full labelling scheme is agreed with the client prior to commencement of work.

Testing of cable channels are performed prior to system hand-over with either a Fluke DTX 1800 cable analyser for copper cabling or a OTDR (Optical time-domain reflectometer) tester for fibre optic cabling.

Warranties & Accreditations
All our installations are performed to the latest installation standards and are supported by a comprehensive hand-over documentation package including test results and warranty guarantee.

CNC are a 3M Certified Installer and Excel Accredited Cabling Partner.  Cabling systems that provide you with the assurance of quality products, backed with 20 year full component and performance warranty.  We are also a corporate member of FIA and Bisci.

Industry Standards
Structured cabling standards are used internationally and are published by ISO/IEC, CENELEC and the Telecommunications Industry Association (TIA). CNC meet all current industry standards and comply with TIA/EIA, ISO/IEC & EN regulations.

Health & Safety
CNC has a policy of directly employing members of staff to form the core installation team, believing it is the only way to ensure that quality and accountability are maintained at all times.  All our engineers are certified data installers and CSCS approved. 

Regular training ensures our engineers are working to the latest industry standards and complying with health & safety legislation.

WIFI (Wireless Fidelity) is the technological standard that allows wireless users to link to each other and to the internet across distances of around 100 metres. The wireless connection is achieved through a Wireless Access Point (WAP) such as wireless router which provides the wireless connection between a laptop for example and the internet service. In commercial offices, WAP devices are connected to a central internet providing device, like a cable modem for example, to spread a WIFI service over a larger area than a home wireless router can cover.

CNC are well equipped to provide both the network cabling to the WIFI outlets whether they be at high level or wall mounted, as well as the installation and configuration of WAP’s and POE’s (Power over Ethernet) which provide both data and power connections in one cable, useful for IP telephones and wireless LAN access points.

Small Electrical Works
We are able to carry out small electrical works such as the installation of power from a distribution board to socket outlets to provide power to data cabinets.
