Here you can see the various "spaces" and cabling subsystems that comprise a basic data centre topology. The architecture here is typical of that deployed for a large

Here is a data centre design that may be used for larger data center's that have either large office and support areas or those in which the distances separating the two is
significant.
In addition, multiple entrance rooms may be required due to circuit distance restrictions. The additional entrance rooms may be connected to the MDA they

Here is a smaller data centre that would support a medium size enterprise. In this design, the main cross connect (MCC) and horizontal cross-connect (HCC) can be
consolidated and be as small as a single cabinet or rack. As in a traditional premises structured cabling system, the Telecommunication Room for cabling to the support areas and the Equipment Room can also be consolidated into the MDA
Standards are created to ensure uniformly high quality of design and performance in many industries. In addition they function to ensure and encourage a high level of competition within the industry so that users receive the best performance at
competitive prices.
Data Centre’s have historically been designed in the absence of rigorous guidelines absence
leading to uniqueness in virtually every data centre. Commercial building owners benefited greatly from the TIA-568 standards. Similarly, designing Data Centre's in accordance with the new TIA-942 standard will help ensure:
• robust data centre design, robust data centre design,
• standardized nomenclature, • ready supply,
• competitive pricing
• scalability for future applications. • interoperability between vendors • easier management

Northgate Info says HQ damaged by UK
blast, Mon Dec 12, 2005 9:40 AM GMT
LONDON (Reuters)LONDON (Reuters) - Software and outsourcing firm Northgate Information Solutions said the company's head office had been seriously damaged by Sunday's massive blast at a fuel depot north of London. Explosions tore through the Buncefield oil depot near Hemel Hempstead just after 6:00 a.m. on Sunday, shooting flames and billowing smoke hundreds of feet into the air. Police said only one person was seriously injured and believed the blast was almost

Four Northgate employees, who were on site at the time of the explosion, were taken to the hospital, and later discharged, Northgate said. Around 300 to 400 staff members would usually be working at Northgate's head office during the week.
Northgate said its financial exposure was limited by insurance policies and that the board was confident the blast's long-term impact on the business was unlikely to be material. Shares in Northgate closed on Friday at 83-3/4 pence.

Conclusion
• TIA TIA-942 is the first standard that specifically addresses data centre infrastructure.
• Primarily a telecom infrastructure standard, but about half of the content deals with facility requirements.
• Provides a flexible and manageable structured cabling system using standard media.
• Builds on existing standards.
• Guidelines on a wide range of subjects useful to someone designing or managing a data centre.
