In order to deliver on these critical business objectives while maintaining a scalable and modular approach, the use of the Dynamic UPS is the Rotary Uninterruptable Power Supply system you can rely on to meet these expectations.

Dynamic UPS uses a kinetic energy accumulator as an energy storage device instead of traditional lead-acid battery cells.

iPlaced between the mains and the load, dynamic UPS acts as a filtering and conditioning mechanism, ensuring high quality power to the load and continues the supply for an unlimited period of time in case of an outage. They range in small power steps from 100 kVA up to 2500 kVA per unit for 50Hz and up to 3000 kVA for 60 Hz. For projects which require large critical loads, the Dynamic UPS can be paralleled and designed in Low Voltage or in Medium Voltage configurations up to 24 kV.

Advantages

Even Higher Efficiency
The design of dynamic UPS enables over 20% of power losses reduction, making it the most efficient Diesel Rotary UPS systems in the market.

ECO-MODE
As every kW counts, the dynamic UPS has been programmed to include an Eco-Mode function -- the speed of the accumulator adapts automatically to partial loads, further reducing energy losses.

100% Uptime
With the dynamic UPS, you are able to perform maintenance programs while the UPS system stays fully operational. In other words, your load is secured at all times and any maintenance work will not interfere with the daily operations in your facility.
Built with the latest technology, dynamic UPS has been referenced by companies worldwide since its conception over 20 years ago. Recently, NewTech supplied dynamic UPS to Global Switch. The whole project sum totaled HKD280 million.
It is engineered to meet the most stringent level of reliability, highest efficiency, long lifespan and consequently, is able to achieve the lowest economical and operational costs.

Enhance Data Centre Performance with DCIM Solution

Nowadays, massive amount of big data are stored inside data centres, buried across the infrastructure. To deal with the enormous data stored and to enhance data centre performance, data centre operators have started to apply Data Centre Infrastructure Management (DCIM) to manage, add, monitor and maintain availability of data centres’ physical facilities such as power distribution, cooling and security system. Data Centre Infrastructure Management (DCIM) empowers data centre operators to manage facilities, optimise the performance and efficiency of data centre infrastructure and keep it aligned with the needs of business at a reasonable cost. DCIM can ensure every aspect of the system’s performance is continuously monitored and managed, hence improving the reliability of data centre. By improving power and cooling efficiency through energy monitoring, DCIM can also reduce energy consumption, costs and carbon footprint. Some operators have integrated wireless sensors into DCIM systems as part of their control mechanism for data centre physical infrastructure. Wireless sensor technology not only allows operators to remotely monitor and manage infrastructure environment through Wi-Fi, it also provides the ability to quickly deploy and requires less wired network infrastructure hence reducing cost spent on cabling and overall energy consumption. As a solution that integrates IT physical infrastructure management, facilities management, and systems management, DCIM is transforming how the IT ecosystem is seen and managed.

Ways to Reduce Energy Consumption in Data Centre

Demands for data centre services have been increasing continuously in recent years. There has also been increasing adoption of high density servers with high energy consumption and heat generation, which in turn require more power for cooling. These together with the power required by other supporting facilities for resilience purposes result in further demand for power which leads to an increase in energy consumption and operation cost. Data centre operators are striving to enhance energy efficiency so as to reduce energy consumption. There are a several ways we can do to reduce energy consumption in data centre:

1. Consolidate and virtualise

Consolidating various applications onto fewer servers has a major impact on energy efficiency by reducing both server energy consumption and cooling requirements. Virtualisation allows enterprises to consolidate all of the servers to a single host machine, hence reducing energy costs and cooling costs as enterprises no longer have to pay for the energy costs associated with running under-utilised systems.

2. Adopting energy efficient servers, UPSs, and PDUs

A recent set of tests conducted jointly by US EPA, HP, and Microsoft demonstrate that replacing an older server with a new ENERGY STAR-qualified model will save energy and can consume 54% less power than older model servers.

3. Deactivating of unused servers

A study showed that one watt-hour of energy savings at the server level leads to roughly 1.9 watt-hours of facility-level energy savings from reducing energy waste in the power and reducing energy needed to cool the waste heat generated by the server. Deactivating of unused servers allows data centre operators to retire servers and/or postpone purchases of new servers, thus reducing electricity consumption and waste heat.

4. Adopt containment system

Many data centres commonly mix hot and cold air, limiting the capacity and effectiveness of the cooling system. To minimise hot and cold air mixing, data centre operators can use a containment system by placing air tiles in the cold aisle, and/or locating supply vents in the cold aisle and return vents in the hot aisle, together with a hard enclosure to contain the cold or hot aisle.

5. Less data storage

Less data storage requires less energy. Deduplication software can be considered as a way to reduce data storage. By eliminating unnecessary copies, deduplication software can compress the amount of data stored by more than 95%. As storing less data requires fewer hardware resources, energy can be consumed less.

Reducing energy consumption in data centre can reduce the operating expense and promote environmental responsibility, thus enabling data centre operators to sustain their business competiveness and growth in the long run.
