Gary Highton, my credentials Sales Director, CableNet Training Services Been in the data-cabling industry since 1985 Very much in the business end since 1989 Supported BICSI concept wherever possible, e.g. 1 st BICSI Middle-East Chair. Would not DARE talk technical to this illustrious gathering

Objectives for the next 40 mins To offer a VERY broad view of TIA-942 Make you aware of some of the PEARLS available to you for Data Centre Design To offer a MODULAR way of filling any skill-gaps you may have in relation to Data Centre Design using TIA-942

Purpose of the TIA-942 Standard Encourage early participation of Designers in data centre design process Fill a void by providing standards for planning of data center's, computer rooms, server rooms, and similar spaces. The standard encompasses much more than just telecommunications infrastructure. Close to half of the technical content deals with facility specifications. Define a standard telecommunications infrastructure for data center's Structured cabling system for data center's using standardized architecture and media. Accommodates a wide range of applications (LAN, WAN, SAN, channels, consoles) Accommodates current and known future protocols, (10 Gigabit Ethernet, 10 Gigabit Fibre & Fibre Channel)

Purpose of the TIA-942 Standard Replaces unstructured point-to to-point cabling that uses different cabling for different applications Specifications for data centre telecommunications pathways and spaces Recommendations on media and distance restrictions for applications over structured cabling system (TIA 232, TIA 561, T1, E1, T3, E3, 1 & 10 Gigabit Ethernet, Fibre Channel) Establish a standard for Data Centre Tiers to replace several proprietary standards. The TIA data centre tier standard is: A tool to evaluate existing data center's A tool to communicate design requirements

TIA-942 Key Facts See handout Key topics covered by TIA-942 Network design; Cabling; Pathways and spaces; Redundancy; Location; Access; Architectural; Environmental design; Electrical design; Fire protection; Water intrusion

Basic Data centre Topology, Basic Data centre Topology, 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 enterprise or an Internet data centre that provides services such as web hosting.

Distributed Data centre Topology Distributed Data centre Topology 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 support using optical fibre, twisted-pair or coaxial cables.

Reduced Data Centre Topology Reduced Data Centre Topology 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 in this reduced data centre topology.

Why Design Your Data centre for Compliance with TIA-942? 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 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, standardized nomenclature, ready supply, competitive pricing scalability for future applications. interoperability between vendors easier management

TIA-942 Tiers What does they mean? A useful definition is The probability of performing a specified function without failure under given conditions for a specified period of time. Tier I, I Tier I is composed of a single path for power and cooling distribution, without redundant components, providing 99.671% availability. Tier II, Tier II is composed of a single path for power and cooling distribution, with redundant components, providing 99.741% availability. Tier III, Tier III is composed of multiple active power and cooling distribution paths, but only one path active, has redundant components, and is concurrently maintainable, providing 99.982% availability. Tier IV, Tier IV is composed of multiple active power and cooling distribution paths, has redundant components, and is fault tolerant, providing 99.995% availability Source: Uptime Institutes

Top-down Computer Room requirements Similar to Equipment Room requirements from TIA-569 Min clear height of 2.6m Min door size 1m wide Min dist floor loading 7.2 kpa/150lbf/ft2, recommended min 12 kpa/250 lbf/ft2 Dedicated HVAC system preferred 20oC to 25oC 40% to 55% relative humidity Signal reference grid equipotential ground reference and reduces stray high frequency signals Any sprinkler systems must be pre-action system

Top Tip Plan for the future Business continuity is key Disaster recovery is not enough

Northgate Info says HQ damaged by UK blast, Mon Dec 12, 2005 9:40 AM GMT 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 certainly an accident. Northgate said the fabric of its head office and fixtures and equipment inside were badly damaged, while back-up systems that were in place have been rendered inoperable. "Northgate's ability to service its customers has therefore been temporarily affected," the company said in a statement, adding that t remote data centres and other company offices around the country would be used to maintain services. 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. HQ closed down, take over 12 months to repair, must relocate but not sure where and how, 150,000sq/ft building difficult to find quickly

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. An official tiering standard for determining the standard quality of a centre. A way to objectively compare one centre with another.
