Track energy consumption and power metrics
Green IT PUE DCiE monitoring

Energy consumption has become a priority focus for many IT managers. From escalating costs for power consumption to carbon footprint concerns, gaining insight into power utilisation is key.

The ability to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres is a topical subject. By monitoring power metrics on power feeders and critical loads to your facility such as amps, kilowatts and kilowatt-hours is a real benefit towards calculating real-time power efficiency (P.U.E. and DCiE) and load balancing.


With OmniWatch's proactive, predictive analysis based on real time power monitoring, organisations can radically reduce the risk of power related incidents and undertake highly effective power based load balancing to maximise performance and minimise energy consumption across the data centre.

Why measure for better efficiencies

Total electrical power consumed by IT equipment in data centres has been relatively stable historically, but new designs for server processors include energy management capabilities that can result in substantial power consumption fluctuations.

This can present potentially numerous problems, including overheating, overloading a circuit breaker and loss of redundancy. However, OmniWatch lets IT departments monitor power and server temperature and therefore provides meaningful real-time measures towards helping reduce unplanned fluctuations in consumption and achieving better efficiency levels.

Catastrophic power loss

Tripping the circuit breaker and taking out the whole data centre is not uncommon. Power related invocations remains one of the top three reasons for business continuity invocation for the last 20 years (also see our article on it here).

Typically servers operate at light computational loads, with actual power draw amounting to less than the server's potential maximum power draw capabilities. However, because many IT personnel can be unaware of this discrepancy, it's easy to plug more servers than are necessary into a single power circuit. This in turn creates the potential for possible circuit overloads, as the circuit rating can be exceeded by the total maximum server power consumption.

Another complication is that when servers are simultaneously subjected to heavy loads, circuit overloads will occur. When circuits are overloaded, the entire circuit can be tripped and power shut off to IT equipment. Furthermore, since this happens as a result of heavy loads, power outages at this time can have significant negative effects on business.

European Code of Conduct for Data Centres

Spook is an approved Endorser of the European Code of Conduct for Data Centres. This EU initiative has been created in response to increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply security impacts. The aim is to inform and stimulate data centre operators and owners to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres.

"Having Spook monitoring our machine rooms and infrastructure is a key component in managing our sites. Spook provides instant, clear notification of infrastructure failures allowing rapid interventions to prevent costly outages. Our peace of mind knowing the sites are constantly monitored by Spook provides real benefits. Spook also measures our PUE and DCiE ratios helping us to improve our power efficiency in real-time."
