Illustrative 48-rack ServerGuard reference design

ASTREON ServerGuard

Know the room. Understand the risk.

Environmental intelligence for server rooms, data halls and critical IT spaces. Combine industrial sensing, local alarms and a reviewable response workflow.

Monitor critical room conditions.

The 48-rack layout is a reference design. Quantities, zones and thresholds follow a survey of your racks, cooling and infrastructure.

Rack thermal

Inlet and outlet readings at top, middle and bottom reveal local hot spots.

Humidity & dew point

Track moisture conditions and the margin to condensation.

Airflow & pressure

Observe aisle containment, obstructions and differential pressure.

Leak & moisture

Zone detection around raised floors, pipe routes and cooling equipment.

Cooling performance

Compare supply, return and room response to investigate degradation.

Fire-system status

Monitor approved fire-panel and VESDA interfaces while certified safety systems remain independent.

Local monitoring. Open integration.

Monitoring, alarms, display and history are designed to continue during internet failure. Cloud access is optional and outbound-only.

Field interfaces

4–20 mA, RTD, supervised contacts and Modbus. BACnet/IP, SNMPv3 and MQTT/TLS are integration options.

Industrial controller

Reference architecture: fanless edge controller, watchdog, industrial SSD, TPM and UPS-backed 24 VDC.

Operator interfaces

Local HMI, beacon, NOC and configured BMS/DCIM integration. Remote notifications use approved gateways.

Accountable history

Record signal quality, acknowledgements, authorized actions and recovery evidence.

From an alarm to a clear next step.

NormalAdvisoryWarningCriticalEmergency

Validate

Check freshness, quality, persistence, hysteresis and rate of change.

Notify

Route severity and context to the beacon, NOC or approved notification gateway.

Guide

Show the zone, observed value, supporting evidence and recommended response.

Close

Record acknowledgement, approved action and recovery in the alarm history.

Start with your room.

1–10 racks

Focused environmental visibility and local alarms.

11–30 racks

Expanded sensing, escalation and integrations.

31–100 racks

Multi-zone reference design with redundancy options.

100+ racks / multiple rooms

Coordinated visibility across rooms and buildings.

Concept deployment scales, not off-the-shelf packages. Final configuration and pricing follow the site survey.

AI-assisted analysis, with operator oversight.

Optional AI can help identify emerging hot spots, cooling degradation, sensor drift and unusual correlations, with evidence for operator review.

AI cannot suppress critical alarms. HVAC actions require authorization and commissioned interlocks. Fire, suppression, emergency shutdown and power isolation remain outside ServerGuard control.

ServerGuard is a system concept requiring site-specific engineering, commissioning and failure-scenario testing. Reference standards describe design alignment, not certification.

Catalogue instruments. Site-specific monitoring.

Temperature and pressure catalogue families provide selection references. Room monitoring ranges, sensor types, quantities and interfaces are specified separately after the survey; catalogue family limits are not ServerGuard performance specifications.
