• Data center basics
• TIA-942 Data Center Standard
• Structured cabling
• Connectivity protocols
• LOMMF in the data center
• Ribbon cable connectivity
Data Center Basics
• Controlled physical area where data processing equipment is
consolidated
• Dedicated to providing uninterrupted service to mission
critical data processing operations
• Important aspects of the data center
–Power
– Cooling (environmental control)
– Security
– Monitoring (NOC)
– Fire detection/suppression
– Network infrastructure
• Cabling infrastructure represents less then 5% of the cost of
the data center and is typically the lowest concern …
Types of Data Centers
• Collocation hosting services
– All switches work management equipment typically owned and
managed by the data center
• Enterprise data centers
– Privately owned and managed corporate, institutional or government
facilities
– Support internal data and transaction processing and Web serving

Functional Areas of a Data Center
Data Center Functional Areas
• Data Center work – work linking
multiple devices in a single geographical location
— 1 Gb and 10 Gb used in the distribution
— 100 Mb and 1000 Mb used in the edge
— Multimode and single-mode
— Dup SC, LC, MT-RJ and MTP® Connectors
Typically Copper
• Data Center work – work linking servers
to storage equipment, which introduces the flexibility of
networking to to servers and storage
— Typically over Fibre Channel 100 MB
