small it rooms
Small IT Rooms
  • Data Centers & Large Computer Rooms
    • Always include a dedicated cooling system
  • Small IT Rooms
    • Many IT devices are located outside computer room
      • Closets /Branch Offices / Storage Rooms / Open Offices
      • Never designed for cooling IT equipment
    • Power density of IT equipment has increased over time
      • Servers / Telecom / VOIP Routers & Switches / UPS
    • Floor Space is a Premium: <100 ft2
    • Contents: 1 – 3 Equipment Racks
    • Heat Load per Rack: 1.0 - 2.0 kW Avg.
    • Typical Cooling: None or Building Cooling During Day
    • Remote location of building
    • Security: Medium
      • Locked Door and/or Locked Cabinet
    • “The average wiring closet contains $150,000 - $300,000 of equipment and a typical small server room often houses more than three times that amount.” - Mitch Medford, NetBotz CTO

Small IT Rooms
  • Approach to cooling small IT Rooms
    • Ignore cooling requirement
    • Deploy equipment … deploy more equipment
    • Call CTM frantically when IT equipment overheats and/or fails
      • Average small IT room can contain up to several hundred thousand dollars of equipment
      • Network down results in more than IT replacement cost
        • Lost sales / productivity / equipment / data
  • Cooling Strategy
    • Requires proactive approach ensuring the uptime availability of your IT network
  • Cooling Strategies for Small IT Rooms
    • Basic cooling principals for small IT rooms
    • Available cooling options

electronic equipment trends
Electronic Equipment Trends
  • Power = Heat
    • Servers
      • Blade Servers
        • Smaller & More Powerful
    • IP & VOIP Telecom Equip
      • High-powered switches and equipment
        • Low-powered legacy
      • Requires UPS support
  • Overheated IT equipment
    • Reduced Life / Hardware Damage
    • Reduced Reliability
    • Slower Network
    • Costly System Downtime
    • General Rule
      • Every 10°C temperature rise in nominal temperatures produces a 50% reduction in the lifetime and long-term reliability of IT hardware- MIL-HDBK 217 / Arrhenius Models

heat problem for small it rooms
Heat Problem for Small IT Rooms
  • Businesses dependent on computers and telecom equipment for day-to-day operations
    • Need to keep IT equipment cool
      • ASHRAE Technical Committee 9.9
      • Thermal Guidelines
        • Inlet Temperatures
        • Costly to rely on building A/C
      • Data Centers
        • Upper range temperatures acceptable
          • Tight controls/monitoring
          • Redundancy
      • Small IT Rooms
        • Temperatures in the 60Fs to lower 70Fs (18 – 22 C) are practical
          • Looser controls/monitoring
          • No redundancy
          • Extend UPS Battery life by 3 times with lower temperatures: 5 years
    • Supplement building cooling
      • After business hours/weekends/holidays
      • Cold-weather months when central system is in heating mode

cooling load
Cooling Load
  • Determining the cooling load in a wiring closet
    • Incremental load from equipment
      • Nameplate rating
        • Usually overstated
      • ASHRAE TC 9.9: Load during operating conditions
        • Not yet adopted by manufacturers
    • Determine cooling load from UPS load
      • Load from all equipment connected to the UPS
      • Dependent on day and time
        • Monitor over a period time to get worst case scenario
    • Other sources of heat
      • Lights/windows/outside wall/etc…
    • Room Dimension: Temp Increases as Room Decreases
      • Ability to dissipate heat
  • Electrical power to rejected heat conversion
    • 1 kW = 3,413 Btu/hr.
      • 12,000 Btu/hr = 1 ton of A/C
