Point out the connectivity opportunities that are associated with each of these opportunities and explain each situation.
This is an example of one of those horror stories you hear about, this site has no structured cabling under the floor. If you have poor airflow to your servers it can have a dramatic effect on the reliability of the equipment. Many data centres require more cooling than they actually need because the cooling cannot effectively reach the servers in the racks. Bad wiring management can be the cause of problems with getting cooled air to the servers.
You can see in these photos how a connector to connector deployment might appear in a data center. The photo on the left shows 1100 modules installed in an 1100 panel in a Server cabinet ready to connect to the servers once they are installed. The picture on the right shows M-series outlets terminated and mounted in a modular patch panel on the Switch end of the connection.
Data maintained for 7 years Engineered to ease installation Rapid Deployment – Faster Mean Time to Productivity Find bad components/terminations prior to install. Similar to InstaPATCH. DTX1800 Testing De-risk product performance and scrap – partially used reels, on-site theft/loss Scalability – add additional harnesses very simply by ordering a single part number – Source/Destination known. 8X Faster – Two people can install a harness in half an hour.
Centralized Switching to TC Cross-Connect or Directly to Server Cabinets Interconnect harnesses No patching at the switch Chassis based switches are hotswappable – Cards/Power/Fan/Management Left 6513 with 8 blades and 1 management card – Need to keep cabling clean so you can swap in 10min. Cable support bar Mockup for Caterpillar 6513 on left Modeled for DC 3 rd rack is server rack Could be done in a TR as well – Retrofit OPPORTUNITIES
You can see on this slide the Cisco Nexus 7000 switch where we have indicated with the yellow arrows the copper ports are arranged in a 6x2 configuration. With the InstaPATCH Cu solution we offer a 6x2 SwitchPack designed to mate to this configuration for the simple and fast connection of 12 copper cables with plugs at one time.
Cisco does have other port configurations as displayed here and we offer SwitchPack versions that mate with each.
Networking standards will not stop at 10Gb/s transmission speeds. But, obviously, the economic viability of 100GbE will depends on the transceiver options, which in turn depends on the PMD (Physical Media Dependent) options. These are several PMD options available for consideration by IEEE: 100GBASE-P10 and 100GBASE-P5 utilise OM3 multimode fibre technology. 100GBASE-P10 uses parallel fibre technology consisting of 10-fibres for transmit and 10-fibres for receive. Each fibre will carry 10G and will use existing 10GBASE-SR VCSEL technology at 850 nm. 100GBASE-P5 uses parallel fibre technology in combination with 2-channel coarse wavelength division multiplexing (CWDM) technology. It consists of 5-fibres for transmit and 5-fibres for receive. It will use existing 10GBASE-SR VCSEL technology at 850 nm. Effectively, each fibre will carry 20G. The remaining PMDs use singlemode fibre technology. 100GBASE-X4 uses CWDM technology with four wavelengths at 25Gb/s each. 100GBASE-X10 uses DWDM technology with ten wavelengths at 10Gb/s each. Obviously, 100GBASE-X10 can use existing 10GBASE-L and 10GBASE-E platforms. The serial PMDs, 100GBASE-L and 100GBASE-E are the most challenging technologies.
With intelligent infrastructure, data centre tasks like adding a new email server to the LAN can be simple and quick. With just three simple steps, server provisioning can be accomplished. Step 1 – select the server port. Step 2 – select the service. And Step 3 – iPatch Intelligent Infrastructure will determine the connection points needed to provide the service. Three simple steps that make server provisioning a snap….Let’s move to the next slide….

Data Centre Cabling Best Practices
Cable Placement and Thermal Management
For every 10 ° C increase above 21 ° C , mean time to failure (MTTF) for active equipment is reduced by 50%
The average large data centre provides 2.7 times more cooling than necessary due to poor airflow management in racks and cabinets
In most data centres 60% of conditioned airflow bypasses data equipment air intakes
Cabling issues consistently ranked as a top contributor to poor cooling in data centres
Standards-Based Data Centre Cable Routing Hot Aisle Cold Aisle Hot Aisle Raised Floor Communications Cabling
Cable Placement: Under-floor or Overhead?
Advantages
Clean appearance
Improved security
Disadvantages
May impede cooling airflow
More difficult to maintain and upgrade
Advantages
Simpler maintenance and upgrade
Will not affect underfloor cooling
Disadvantages
Appearance
Decreased security (cables exposed)

Server Virtualisation Driving the Need for 10G
Studies show that average usage rate of stand-alone servers is only around 20%
Virtualisation allows multiple applications to run on the same server
Provides better utilisation of servers, rack space AND power
Uplink must be able to handle increased traffic load 10G cabling required!
Virtualisation Study : Annual Power and Cooling savings of €570 per virtualised application Source:
10GBASE-T Equipment Already in the Market Transceivers Adapters Switches Testers
LAN on Motherboard 10GBASE-T Server Ports
LOM removes the cost barrier to adopt 10G on servers.
10G Server LOM expected in 2010/2011
Server vendors require LOM to be backward compatible, hence LOMs should support:
interoperability with 100M/1G/10G switches
support RJ45 cabling infrastructure
10G NIC

You may take it for granted but cabling is the esse more
You may take it for granted but cabling is the essential building block when it comes to the data centre. The decision on how and what to use in order to weave your data conduit tapestry requires knowledge. This session will help you understand and answer the following:
* Should I install copper or fiber?
* What category of copper and what type of fiber?
* Should I go with a combination of both?
* If I use both again what category and grade of each?
* what's on the horizon less
