IT infrastructure Design Concepts
Network Design Philosophy Data center Design Philosophy •Security, •availability, •scalability, •manageability.
Security•Network designed to prevents unauthorised access identify and isolate illegal actions.•Usually neglected in the physicallayer.•Critical to monitor both logical &physical connectivity.•Asset management
Availability•Networks are designed to minimize theoccurrence of service problems•Redundancy based design.•Capacity to be higher than minimum tocater for increased traffic loads bandwidth intensive applications•SlowtimeTMNetwork must not only be up butthroughput must be maximised.•High performance / bandwidth solutions
Flexibility / Scalability •Ability to grow with your business •System must adapt to ever- changing network requirements •Scalable deployment of network services speed of deployment optimise existing investment
ManageabilityKISSManaging a network should be easy designed for dummies real time informationFacilitate upgrades and maintenanceFlexible to meet any suddenchanges.
10 Gigabit Ethernet IEEE 802.3an 10 Gigabit Ethernet on twisted pair cabling standard completed in July 2006Objectives •35m over Cat 6 UTP cabling •100m over augmented Cat 6 cablingcurrent cabling may not support 10GBase-T. •Existing Cat 6 cabling need to be qualified to TSR 155 / TR24750 •New cabling standard Cat 6A to be published under EIA/TIA 568b.2-10
Normal fiber operating windows 1.2 O E S C L U 0.9 Conventional Fiber Loss (dB / km) 0.6 Loss 0.3 0 Wavelength (nm) 1250 1300 1350 1400 1450 1500 1550 1600Why are there no applications @ 1400nm? ANSWER: HIGH LOSS!!! 1350nm to 1450nm (E-band) traditionally no operation due to high loss.
E-band Standard Fiber Partially Blocked by Water 1310 nm band Lanes Closed 1400 nm band 1550 nm band•1280 to 1625nm•highest loss at 1383nm•loss caused by hydroxl ions in the glass•traditional manufacturing process unable to remove these ions.•Commonly known as “Water Peak”•Ordinary singlemode fiber (G.652 compliant fiber) suffers fromthis problem.
Zero Water Peak Full Spectrum fiber Singlemode Fiber− 9um SINGLEMODE− G.652.C compliant− no water peak− removes Hydroxl ions from fiber− Increases capacity per Fiber − Due to elimination of water peak causing high loss − 60% more usable wavelengths − Maximizes support for CWDM / DWDM− Low Cost Future Proofing for Next Generation Equipment

High availabilty requires − high capacity medium to avoid network congestion Scalabilty requires a medium that − supports current network methodology − supports current technology − flexibility in exploiting new technologies Design concept 1 Design shall provide 10Gigabit Ethernet &support next generation technologies (DWDM)
Data center considerations• Fast installation •Installer spend less time in data center •shorter cut-over• High Performance •minimise down-time •Low loss allow for flexibility in design• Minimise space used •Data center high cost due to supporting facilities• No chemicals •confined areas - fumes difficult to disperse •prevents accidental fires / damage
Connector Options Connectors • Modules support wide range of connectors – SC, ST, LC • Modules connect to trunk – MTP connectors. MTP connectorSC, ST, LC, MTRJ connectors
Plug & Play • Improve installation time by as much as 70% • Saves up to 60% rack and floor space • No site terminations, no chemicals • Factory terminated & tested for high performance
Scalabilty requires − rapid deployment / expansion − factory terminated performance Manageability requires − lower cable counts for easy handling Design Concept 2Datacenter cabling shall be preterminated for fast deployment & expansion
Angled Patchpanel Vertical Cable Manager Angled Patchpanel Allows cables to be routed directly to vertical CM. No need for horizontal cableCISCO 6500 series managers
Angled Patchpanel •Eliminates Eliminates horizontal cable mgrs. Double Your Density ! •Saves floor Saves space & rental.

Manageability requires − patchcords to be routed easily and neatly − both equipment and patchpanel − ease of search − patchcords to maintain bend radius Scalability requires − space to be maximised for future expansion Design concept 3Patching solution must be based on angled patch design.
Integrated Network MonitoringTraditional Network Management System (NMS) Monitors active equipment. Gives info on logical level. No info at the physical level. ROUTER SWITCH PATCHPANEL DEVICES Network Mgt solution
Integrated Network MonitoringIntelligent cabling integrated with NMS Monitors both active and passive devices. Gives complete physical & logical information. Complete real time information on network. Aids troubleshooting & maintenance. ROUTER SWITCH PATCHPANEL DEVICES Network Mgt solution Intelligent cabling solution
Manageability requires − always knowing how your cabling are patched − integration of physical layer with network monitoringSecurity requires − any unauthorised changes to be tracked Design Concept 4Cabling system shall be supported by a intelligent cabling system
