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.”

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 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 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 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

Cooling Solutions & Best Cooling Practices Cooling Solutions
Primary cooling for IT equipment Small IT room is not air conditioned
Nights & Weekends when building a/c is off Shut down building a/c when people are not in the building
Supplemental Cooling Added denser IT equipment Seasonal: Summer or Winter
Redundancy / Emergency backup to primary cooling Planned or unplanned shut downs: Inexpensive insurance plan
Best Practices Spot Cool vs. Traditional A/C
Managing Air Movement Direct cold air to front of server: Airflow = Front to Back
Do not cool down the entire room Back of the rack: Up to 36°F Hotter
Cold Aisle / Hot Aisle Use blanking panels for unoccupied rack space
Organize cabling Maximize airflow
