Getting started with machine learning with Caffe
By DE Newsroom Published: 00:00, 7 September, 2016 Updated: 00:00, 7 September, 2016
Many data centres are being touched by machine learning, as organisations increasingly seek out opportunities to use it for understanding their customers better, designing improved products, or automating manual processes. Here’s a tutorial that will quickly bring you up to speed on Caffe, a deep learning framework from the Berkeley Vision and Learning Center. It’s integrated with the Intel® Math Kernel Library 2017 to deliver optimal performance.
The tutorial takes you from installation, through a discussion of the data types and dataset preparation, into training the model, fine-tuning and testing. There’s also a guide to using the Python API for Caffe, which is handy in testing, classifying and feature extraction. If you can’t get it working, check out the debugging guide.

Metronode datacentres achieve Nabers 4.5-Star rating
By DE Newsroom Published: 00:00, 25 November, 2016 Updated: 00:00, 25 November, 2016
Australian datacentre company Metronode has announced that one of its data centres was the first Australian facility to achieve a NABERS 4.5-star rating. And in a significant end-of-year boost, two additional Metronode data centres have this week been awarded NABERS 4.5-star ratings.
A first for Australia, the three Metronode NABERS 4.5-star rated facilities – Silverwater and Unanderra in NSW and Derrimut in Victoria – are also the most energy efficient datacentres in the country.
Metronode Managing Director Josh Griggs said that the company’s superior engineering and energy efficient technologies were key elements in achieving the NABERS star ratings.
“Energy efficiency is critical for our customers who not only want to house their data in secure, adaptive facilities but also want to lower their overall expenditure.
“Power costs will continue to rise and Metronode’s combination of engineering excellence and cutting-edge energy efficient solutions are setting new benchmarks in Australia,” Mr Griggs said.
The data centres in Silverwater and Unanderra are a result of the NSW Government’s Data Centre Reform Project, in which 130 data centres were consolidated into the two centres that comprise GovDC.
“GovDC’s commitment to 4.5-star rating is a testament to good practice and a dedicated approach to a sustainable data centre consolidation program,” said Derek Paterson, Director GovDC and Marketplace Services.
HKT to construct major submarine cable linking Tseung Kwan O and Chai Wan
HKT, the largest telecommunications network operator in Hong Kong, plans to build a super high-capacity, submarine fibre-optic cable system that will connect Tseung Kwan O Industrial Estate to Chai Wan from the second half of next year.
Ultra Express Link is a 3km submarine cable system with a target ready for service date in 2017. Providing robust, reliable, lower latency and diversity connectivity, Ultra Express Link will foster the development of TKOIE to become Asia’s datacentre hub.
Mr. Alex Arena, Group Managing Director of HKT, said, “The building of Ultra Express Link demonstrates once again not only our leading position in solid fibre infrastructure in Hong Kong, but also our dedication to build Hong Kong into a regional datacentre hub. The new cable, together with the existing extensive fibre infrastructure provided by HKT, will allow us to meet the rising demand for high speed and high capacity connectivity requirement from datacentre operators.”
Mr. Arena added, “HKT is the only operator to provide full diversity with different options of cable route across Hong Kong. We have full fibre coverage in all datacentres in Hong Kong, particularly with diversity paths in all datacentres in TKOIE.”
Komatsu chooses BT for its global IT infrastructure
BT has announced a contract with international mining and construction equipment manufacturer Komatsu for a new global IT infrastructure covering 26 sites across 15 countries in Europe, Asia-Pacific and South-America.
BT will design, build and manage a resilient, hybrid network combining BT’s IP Connect Globalwith its hybrid service (hVPN) for smaller locations, which lets office-based workers securely access their corporate network through the internet.
Komatsu’s business critical voice traffic for around 1,100 employees will be routed using BT’s One Voice centralised SIP trunking service – replacing traditional voice services with voice-over-IP technology. BT’s biggest customers lower their costs by up to 34 per cent by switching to BT One Voice.
It is important for Komatsu that its new provider possesses strong datacentre and cloud services integration capabilities, as it foresees to migrate a number of its enterprise applications to the cloud over the coming years.
As a first step, BT’s professional services team, BT Advise, will consolidate Komatsu’s central IT infrastructure in two BT datacentres. BT Compute datacentre services in-scope include telehousing, internet access and load balancing – improving the distribution of workloads across multiple computing resources.
Chris Borremans, CIO at Komatsu Europe, said: “Today’s agreement is the start of a journey whereby we will be moving towards flexible, cloud-based services supporting our operations, customers and employees across the globe. We believe that BT is the right cloud services integrator to help shape our roadmap and realise our vision.”
Fabrice De Windt, BT’s CEO for the Benelux, said: “We are very proud that Komatsu has selected us for its global IT infrastructure. This opens the path for an ambitious digital transformation journey, supported by our Cloud of Cloudsportfolio strategy. We are looking forward to demonstrating how our global capabilities will drive great business outcomes for Komatsu.”
STULZ takes the heat off with its new Explorer WSW water cooled chiller
STULZ, a global provider of energy efficient temperature and humidity management technology, has announced the launch of its pioneering STULZ Explorer WSW water cooled chiller. This flexible chiller unit is designed for use in a diverse range of mission critical indoor applications including datacentres, communications rooms, industrial and commercial buildings, and telecommunications equipment centres.
Flexibility has been designed into every aspect of the STULZ Explorer WSW and it has big cooling power in an incredibly small footprint. Depending on the required cooling capacity, the Explorer WSW chillers can be equipped with either one compressor offering a cooling capacity of 230-430kW, or two compressors that provide 460-1530kW. Further enhancing its ease of use, it can be easily adjusted to different heat loads thanks to its two refrigerant circuits with semi-hermetic screw compressors and infinitely variable output sliders.
The Explorer WSW features standardised components including shell and tube condensers that can be set to operate at different temperature levels, for example, with well water, cooling towers or external recooling heat exchangers. The evaporation process in the refrigerant circuit is controlled by electronic expansion valves, which use pressure sensors, temperature sensors and the STULZ C2020 controller to optimise heat exchange between the refrigerant and chilled water in the evaporator.
Thanks to its versatility, this latest innovation from STULZ also impresses with high efficiency in partial load mode. Depending on the service conditions, it can offer European Seasonal Energy Efficiency Ratio (ESEER) values of five or higher and also offers a variety of options such as automatic transfer switch, an energy meter for measuring total power consumption, soft start and anti-vibration mounts.
Brendan Leonard, Managing Director at STULZ UK Ltd, commented: “Ensuring that mission critical equipment maintains optimal temperature is essential as the consequences of excessive heat can be disastrous. We are therefore delighted to be able to help solve this issue with the Explorer WSW and its easy to use, touch controlled interface that offers the ultimate user experience and valuable peace of mind.”
