Data centers / Cooling and capacity

Cooling and capacity for data centers

Edviro fits a physics model to your own telemetry, keeps it calibrated, and shows how much cooling headroom each pod has. You can try a new row, a unit failure or a setpoint change on the model before anything changes on the floor.

Read-only. Nothing new installed. Your team decides every change.

How do you measure data center cooling headroom?

Cooling headroom is how much more IT load a room or pod can take before rack inlet temperatures cross the design limit. Edviro works it out with a physics model calibrated to the site’s own BMS, power and sensor telemetry, and checks the model against measured temperatures. Operators can then try changes such as new racks or a unit failure on the model first.

Why capacity ends up a guess

Design-day estimatesCapacity was worked out on paper, years ago, for a different layout.
Over-provisioningCooling is held in reserve because nobody can show it’s safe to use.
Hot spots after the factA new row goes in, and then row C runs hot every afternoon.

How the model works

Edviro fits a physics model to your own telemetry and recalibrates it as load and layout change. Pod 3 on this page is a made-up example.

Calibrated

The model is fitted to the site’s own BMS, power and sensor telemetry, continuously.

Checked

Modeled inlet temperatures are compared with measured ones and the gap is shown. In the Pod 3 example it is ±0.4 °C, an illustrative figure.

Headroom

Each pod shows its current load, its modeled limit and the headroom between them.

Try a change on the model first

Add high-density racksHow many more racks can Pod 3 take before cooling runs out?
Unit failureIf CRAH-2 goes down, which rows cross the inlet limit, and how fast?
Raise supply airCan we raise supply air a degree without creating hot spots?
Find the hot spotWhy does row C run hot every afternoon?

What Edviro can and can’t change

Read-onlyNothing new is installed, and Edviro doesn’t write to the BMS.
Model onlyEdviro reads, diagnoses and models. It doesn’t operate the cooling plant.
Your team decidesChanges to the floor or the plant are made by your team and vendors.
Capital decisions

Add racks, replace a unit or wait

Add loadSee which pods have headroom before placing new IT load.
Replace or repairCRAH units and chillers ranked by risk and service history.→
Defer spendCheck whether the room can take the load before buying more cooling.

Questions about cooling

Is this CFD?

No. It’s a model fitted to your own telemetry and recalibrated continuously, where a CFD study is usually done once.

Does Edviro change setpoints?

No. It models the change. Your team decides and makes it.

What data does the model need?

BMS, cooling plant (CRAH/CRAC, chilled water), power and rack inlet sensors.

How accurate is it?

Edviro shows modeled against measured inlet temperatures for your site, so you can see the gap yourself. The Pod 3 figures on this page are illustrative.

Does it handle liquid cooling?

That depends on the site. We’ll go through it with you on the demo call.

Can we plan a new build?

You can test changes against the model before you build. How far that goes for a new site is something we’ll go through on the demo call.
