A Data Center

Highly secure, fault-resistant facilitieshousing equipment that connect totelecommunications networks. The

facilities accommodate servers, switches,routers, modem racks. Data centerssupport corporate data bases, web sites

and provide locations for CLECs, ISPs,ASPs, Web hosting companies, DSLproviders and other IT services.

Rack Location Units

A standard for measuring equipmentspace in a data center is RLUs or RackLocation Units

Criteria

The Budget $

- What is the available budget?

- Can the scope of the project beachieved with the current budget?

- What are the actual funds needed to

create the data center?- How will funds be distributed & can

they be redistributed?

Criteria Continued

System Availability Profiles

-Categorization

-Device Redundancies

-Power Redundancies

-Cooling Redundancies

-Network Redundancies

Structural Aspects

When dealing with a raised floor ceilingheight matters.

Basement data center locations near

water are not a good idea.Their must be a pathway for equipment tobe moved in & out of the data center.

Make sure the floor where the data centeris to be located is rated for the estimatedload.

Power

Adequate power

Surge suppression

Proper grounding of equipmentCable Layout

Power Redundancy

Forms of Power Redundancy

1. Battery-feed UPS

2. Power Generators


11/22

Networking

Each cabinet needs be to supplied withappropriate connection media: Cat6copper, multi-mode fiber, and/or single-

mode fiber

Proper cable

management should

be implemented

Past to Future

Technology changes continuously makingversatility a primary focus in a Data Center.

At one point in time a single computer occupiedthe space of an entire Data Center. That samespace can be occupied by thousands of serverstoday.
