Data centers / Alarm diagnosis

Alarm diagnosis for data centers

Edviro groups related BMS, EPMS and PDU alarms, compares them with how the site normally runs, and names the likely cause with the evidence. Your operators get one fix to approve.

Read-only. Nothing new installed. A person approves every fix.

What is alarm root-cause analysis for data centers?

Alarm root-cause analysis groups the alarms a data center’s BMS, power and environmental systems raise and traces them to the fault behind them. Edviro reads that telemetry read-only, learns how each unit and room normally behaves, ties related alarms together by time, location and equipment, and names the likely cause with its evidence. Operators get one fix to review.

Why alarm lists don’t help

Raised per pointA BMS alarms point by point, so one fault trips dozens of them.

RepeatsThe same alarm clears and comes back all week. People stop looking.

Buried faultsThe one alarm that matters sits on page 4 of the list.

No contextThe alarm says which limit was crossed. It doesn’t say why.

How it works

No alarms, just fixes.

There is no alarms tab in Edviro. It triages every alarm, groups the related ones, and hands your team a diagnosed fix that is ready to approve.

Collect

BMS points and alarms, EPMS and PDU power, and sensor feeds. All read-only.

Group

Alarms are tied together by time, location and equipment: unit, row and pod.

Compare

Behavior is checked against the learned baseline and the cooling model.

Name the cause

Edviro names the likely cause and lists the evidence and the alarms it explains.

Example: a diagnosis for CRAH-2

An example with made-up numbers. Pod 3 raises 312 alarms in 24 hours, and one fix reaches the team.

Likely cause

CRAH-2 chilled-water valve stuck at 40%.

Alarms tied

The diagnosis ties 41 alarms together.

Evidence

Fan pinned at 100% for 3 days. Low ΔT (3.1 K) on CRAH-2 only. Row C inlets climbing each afternoon, to 27.4 °C.

Next

A drafted fix, ready for the site lead to approve.

Faults behind alarm floods

Sticking valvesA chilled-water valve stuck part-open, with low ΔT and the fan pinned.

Fan saturationCRAH/CRAC fans at 100% to cover for a fault somewhere else.

Airflow leaksMissing blanking panels and hot spots in one row.

Sensor driftA humidity or temperature sensor slowly reading wrong.

Power anomaliesPDU and UPS load and alarms that are out of pattern.

Units fightingNeighboring units humidifying and dehumidifying at the same time.

What happens after the diagnosis

Signal

Alarms from the BMS, EPMS, PDUs and sensors.

Diagnose

The likely cause, with evidence.

03Human

Review

The site lead approves the fix.

Dispatch

The technician gets the unit history and the steps.

Verify

Edviro checks that supply temperature holds inside the model band. The pattern is kept, so the same fault is recognized sooner next time.

What it connects to

BMSDCIMEPMSPDUSensors

Access is read-only. Edviro never acknowledges, suppresses or changes alarms in your BMS. It connects to major DCIM, BMS, EPMS and PDU systems through open protocols or APIs, and fixes go to the operator list or your ticketing.

Questions about alarm diagnosis

How is this different from BMS alarms?

A BMS raises alarms per point. Edviro compares behavior with a learned baseline, groups related alarms, and names the likely cause with the evidence attached.

Does Edviro change or silence our alarms?

No. Access is read-only. Your BMS alarms stay exactly as they are.

What data does it need?

BMS points and alarms, EPMS and PDU power, and the environmental sensors you already have.

How long until diagnoses are useful?

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

What if the diagnosis is wrong?

A person reviews every diagnosis before a fix goes out, and the outcome is fed back into the model.

Does it work in colocation?

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