A photo of heaters for heat load testing datacentres

So you are about to conduct a test of your new data centre or IT Equipment (ITEC) Room. What is the best type of load to use? Before you can make this decision, you need to answer some questions:

What type of test are you conducting, is it;

• an electrical load test?

• a test of the cooling system?

• Or both?

What type of test are you conducting; basic room level or accurate test?

During the design process the facility may have been modelled using Computational Fluid Dynamics (CFD), which also should represent the eventual IT layout. Accurate testing will confirm the CFD model.

What will the final operational layout be and what will the layout be at the time of the test;

• will the IT Racks installed at the time of the test or will all IT equipment be floor standing?

• how are the aisles laid out?

• is there cold aisle or hot aisle containment?

• is there a hot air return exhaust system?

• will the IT layout be linear with an average kilowatt (kw) rating across the room or will each position have an individual kw rating?

• will the IT layout assume a linear (heat rise from front to back of equipment (delta-t) or will different positions require unique delta-t?

What power distribution is available at the time if testing;

• single or 3-Phase?

• are commando type sockets available or hard wire into power distribution?

• will the power strips be installed in within the IT Racks?

• what type of power connectors are available on the power strips?

• is there sufficient power distribution to meet the kw rating of all positions?

• how will the load be split between supplies (A+B)

The most accurate way to test a datacentre or ITEC room is to use load that represents the eventual use once the facility has been handed over to IT. The temporary load should represent the IT equipment in terms of location, kw rating and delta-t.

Choosing a heat load

HeatLoad offers a variety of heat load and server emulator products and services to meet your testing requirements, these include;

• floor standing and rack mounted units

• single and 3-phase

• basic heat load and server emulators that accurately replicate IT equipment thermal characteristics

• temporary 3-phase 250Amp power distribution

• power adapters to connect to facility power distribution and power strips

To further represent the layout of the facility, HeatLoad can;

• construct temporary walls within the facility to represent walls and containment not yet constructed

• install temporary blanking within IT racks to prevent air recirculation

• supply temporary IT rack in positions where the permanent racks have not yet been deployed
