DATA CENTRE CONNECTIVITY
CENELEC EN 50173-5
How the physical infrastructure is changing
Data Centre Design Requirements
Correct management of the data center’s physical layer infrastructure can have a direct impact on network operation and facilities
Advanced cabling solutions that allow for adaptive design of the physical infrastructure to meet unique data centre requirements is the key to success
Solutions that provide data center’s with a flexible solution that will extend the life of the cable plant, reduce obsolescence, and offer a clear upgrade path to future applications
Challenges of a Data Centre
Managing Downtime – Planned or OutagesAssessing remote back up requirements
Company Technology RoadmapCurrent & future technology requirementsMainstream or early adopter
Environmental Control / Fire PreventionUse of high-density storage & server technologiesIncreased demand for power and coolingVentilation – “Hot Spots”
Challenges of a Data Centre
Redundancy and diversityFor HVAC, electrical, water, etc.
Tiered SecurityPush-button entry pads, electronic swipe cards, advanced biometric scanning devices

Optional cables
EN 50173-5: Data Centre Cabling Overview
Class E minimum performance balanced copper channel plus Alien Crosstalk requirements
Physical length of channel shall not exceed 100 metres, 90 metre fixed cable length shall depend on the length of cords used.
When using an LDP these should be positioned at least 15 metres from the ZD.
When 4 connections are used in a channel the physical length of the network access cable should be at least 15 metres
Recommended patch cord length extended from 5 to 10m
Optional links allowed between LDP’s for added resilience
EN 50173-5: Data Centre Cabling OverviewIndustry standard duplex SFF connector for use at ENI
» telecom services require >55dB return loss for Singlemode» LC connector expected to be used in majority of cases
Industry standard duplex SFF connector for use at EO» either LC or MT-RJ connectors may be used
OF-300 (OM2 or OM3) minimum performance fibre channel
RJ-45 Cat 6 connector adopted for use at EO with 4 pairs
Terra & RJ-45 Cat 7 connectors for use at EO with 4 pairs
Wish to support up to 8 optical connectors per channel
Critical Considerations for Physical Infrastructure
Security• Safe from external and internal attacks• Reduce risk: likelihood, frequency & impact of loss events
Reliability• to meet required service levels• more critical applications
Management• reduce operating costs• provide a “complete”
view if the networkScalability• reduce capital expenditure• ease expansion• support new applications
Data Centre Connectivity Requirements
Network Efficiency - High performance, reliable, stable, high density (low profile) solution. Effective overall operation.Manageability - Increased control of the data centre infrastructure.Flexibility - Quick and easy moves and changesScalability - Fast and easy provisioning of connectivity equals a more efficient deployment of system equipment. Scalable bandwidth 10/100/1G/10G
Ventilation “Hot Spots”
COLDAISLE
HOTAISLE
Area of a data center where heat builds up due to one or more contributing factors such as heat dissipation from equipmentor a poor cooling design
Equipment layout- Front to front on cold aisle w/perforated floor tiles blowing cool air – dissipated w/equipment fan
Back to back on hot aisle w/solid floor tiles using fan exhausts
Eliminate Hot Spots

Structured vs. Unstructured Cabling Solutions
Server racks The cabling starts with a few connections . . .
Storage
• No defined cable paths
• Changes made at active equipment
• Problem determination difficult
• System growth can be impacted
• Mess under the floor
And this is how it ends up . . .

Careful Planning of Data Centres
Careful Planning is essential
All components used should be designed to work together
Flexibility is key to ensure future requirements are met
Poor planning can lead to extra costs when changes are required
New Challenges for the “Heart” of the Enterprise New and retro-fit designs• Cooling, power, and grounding become even more critical • Cable management in “premium space” • Rack space “conservation” - BIG hardware• Security is “top of mind”
– Bullet-proof glass– Biometric authentication– 24x7 video surveillance– Redundant generators (90 day fuel supply)– 50k sq. ft. bunker for 25 megaton nuke blast
