  1. Data Center Design Christopher Geyer

  2. A Data Center Highly secure, fault-resistant facilities housing equipment that connect to telecommunications networks. The facilities accommodate servers, switches, routers, modem racks.  Data centers support corporate data bases, web sites and provide locations for CLECs, ISPs, ASPs, Web hosting companies, DSL providers and other IT services.

  3. Rack Location Units • A standard for measuring equipment space in a data center is RLUs or Rack Location Units 1U 2U 3U 4U…

  4. Elements of a Data Center • The Site • Command Center • Cable Management • Network Infrastructure • Terminal Servers • Environmental Controls • Power

  5. Criteria • The Budget $ -What is the available budget? -Can the scope of the project be achieved with the current budget? -What are the actual funds needed to create the data center? -How will funds be distributed & can they be redistributed?

  6. Criteria Continued • Physical Constraints: -Available Space & Weight of Equipment -Power Requirements -Cooling -Bandwidth

  7. Criteria Continued • System Availability Profiles -Categorization -Device Redundancies -Power Redundancies -Cooling Redundancies -Network Redundancies

  8. Structural Aspects • When dealing with a raised floor ceiling height matters. • Basement data center locations near water are not a good idea. • Their must be a pathway for equipment to be moved in & out of the data center. • Make sure the floor where the data center is to be located is rated for the estimated load.

  9. Power • Adequate power • Surge suppression • Proper grounding of equipment • Cable Layout

  10. Power Redundancy • Forms of Power Redundancy 1. Battery-feed UPS 2. Power Generators

  11. Networking • Each cabinet needs be to supplied with appropriate connection media: Cat6 copper, multi-mode fiber, and/or single-mode fiber • Proper cable management should be implemented • Over Flow

  12. Security • Physical Access • Levels of Access • Monitoring

  13. Past to Future • Technology changes continuously making versatility a primary focus in a Data Center. • At one point in time a single computer occupied the space of an entire Data Center. That same space can be occupied by thousands of servers today.

  14. Expandability • Create more RLUs than current needs dictate • Power Distributions Unit (PDU) • HVAC • Physical Space

  15. Example RLU Definitions Power: 3.42 BTUs per Hr = 1 watt Bandwidth: -inbound and outbound bandwidth specifications -Media type requirement Weight: -Weight of the equipment Physical Space: -Width and depth of rack chassis -Cooling Dimensions Functional Capacity: -Needed to determine quantity of servers for a particular RLU definition 1 2 3

  16. Example RLU Definitions

  17. Disaster Preparation • Natural Disasters -Flooding -Seismic Activity -Temperature Extremes -Fire • Human Disasters -Industrial Pollution -Electromagnetic Interference

  18. Overview • What equipment will the data center contain? • What will be the RLU definitions? • What are the required utility feeds? • How many RLUs will be needed? • What are the limiting factors?
