01   FOUR RESOURCES · ASSET · U-SPACE · RATED POWER · COOLING CAPACITY

Data centre management is fundamentally about the headroom and allocation of four resources

The data centre operations framework groups infrastructure resources into asset, U-space, rated power and cooling capacity. Of the four, U-space and cooling capacity depend most on on-site data — and are most often missing.

01

ASSET

Asset

Automatic capture of the identity and occupied U position of installed equipment forms a continuously auditable asset register and a real-time record of each asset's physical location.

02

U-SPACE

U-Space

U occupancy visible in real time: free U positions, available mounting positions and fragmented space; installation approval no longer depends on a site survey.

03

RATED POWER

Rated Power

Combining rated power with real-time consumption to determine rack power density (kW/rack) and distribution headroom, and to identify high-density racks.

04

COOLING CAPACITY

Cooling Capacity

In-rack temperature distribution and ΔT (intake-to-exhaust) to judge cooling delivery effectiveness and locate hot and cold spots.

02   ASSET VISIBILITY · REGISTER MATCHES REALITY

A register that matches reality is the precondition for every O&M decision

The value of an asset register depends on how well it matches reality. Manual inventory gives a point-in-time snapshot; rack-level sensing gives continuous, auditable real-time state.

  • U-level identity and location: automatic capture of the identity and occupied U position of installed equipment, with automatic detection and position update on relocation.
  • Unauthorised-change alarms: real-time alarms for unauthorised installation or removal and position changes (covering 100% of change events).
  • Second-level inventory: full inventory time reduced by 99% against manual methods, with 10× the inventory efficiency.
  • Auditable: change events are recorded, meeting internal control and compliance review needs.
03   CAPACITY · U-SPACE / RATED POWER / COOLING CAPACITY HEADROOM

Three prerequisites for an installation decision: whether U-space, rated power and cooling capacity remain sufficient.

Capacity planning is often conservative for lack of on-site data — sizing installed capacity from nameplate power leaves cooling over-provisioned overall yet locally too hot. Rack-level sensing makes all three kinds of headroom measurable and predictable.

01

U-SPACE

U-space headroom

U headroom and deployable equipment density counted by rack and by room.

02

RATED POWER

Rated power headroom

Rack power density (kW/rack) and distribution headroom, identifying the high-density racks that need attention (e.g. >5 kW).

03

COOLING CAPACITY

Cooling capacity headroom

Intake temperature and ΔT headroom, used to assess how much additional load can still be supported without breaching thermal limits.

04   THERMAL MANAGEMENT · HOT SPOT / COLD SPOT / ΔT

Hot spots are usually about airflow, not cooling capacity

Industry research indicates that around 10% of racks run above recommended temperatures; the root cause is often bypass airflow and recirculation, with unblanked unused U positions among the most common triggers. Locating the problem requires in-rack, U-level temperature data.

  • U-position temperature sensing (in-rack, U-level) — outputs the temperature distribution along the height of the rack, judging whether the intake air at each U position is within the recommended range and identifying cold/hot spots and temperature stratification inside the rack.
  • ΔT (intake-to-exhaust) — outputs intake temperature, exhaust temperature and the ΔT between them; an elevated ΔT is direct evidence of an airflow problem, with 99% alarm accuracy.

Field experience shows that targeted airflow adjustment based on rack-level temperature data improves cooling delivery effectiveness by 20%.

05   CORRELATED TELEMETRY

Correlate “the U position where the temperature shift occurs” with “the rated power of the device at that U position”

A single temperature reading is just a number; correlation is what turns it into a judgement. The system aligns multi-dimensional data on one timeline.

Correlated telemetry view
  1. Resolution reaches the rack, U position, device and power levels, rather than the vague “this rack runs 2 °C high”.
  2. Capacity decisions return headroom for U-space, rated power and cooling capacity at the same time.
  3. Efficiency work shifts from “cool everything” to “allocate cooling on demand”, delivering around 10% measured energy saving while meeting reliability constraints.

07   INTEGRATION · COEXISTING WITH EXISTING PLATFORMS

We do not replace DCIM — we supply DCIM with rack-level data

The rack-level sensing layer outputs data upwards through standard interfaces, integrating with existing DCIM, environmental monitoring, ITSM and automation platforms to avoid duplicated build-out.

  • Events and alarms: position change, unauthorised operation, temperature threshold breach, ΔT anomaly
  • Optional add-ons: 3D digital twin (HorizonView) and VR guided inspection
  • Deployment: on-premises / edge / hybrid
