If you don’t test your back-up power, don’t expect it to work!
Datacenter.com – Last week we again conducted a black building test. This time including the power expansion which will be active soon. We always have full confidence in our black building test, but it’s good to test this regularly. After a series of power outages at various data centers, we ensure there is a power supply when you really need it.
If the power goes out for a short or long time, that is of course annoying if your favorite TV show was just on TV. But if a power outage means that your critical IT infrastructure no longer works, there are far-reaching consequences for your company. How is a power outage picked up by Datacenter.com.
For companies, organizations and governments, reliable power supply is one of the most important reasons for placing their IT equipment in a data center. Recent high-profile data center failures brought the issue of reliability to the fore. Historically, data center power cuts have been experienced by many blue-chip banks and telecoms providers, so no-one can claim immunity from such problems.
To guarantee the reliability of that power supply, we test our emergency power supply on a monthly basis. During such a test, we activate the generators to ensure the redundant power supply path works appropriately. By setting up a switch that starts our redundant set of emergency power supply, synchronizes with the mains, and delivering power to the IT equipment. During regular generator tests, the generator is putted next to the grid so the equipment that is not behind UPS remains switched on. This means that the cooling system and the lighting will continue to work during such a test. more>

Electrolux implements worldwide 3D factory and material flow planning
Siemens – Based in Stockholm, Sweden, Electrolux AB sells appliances for household and commercial use in 150 countries around the world. With around 58,000 employees and 46 production sites, the company develops and manufactures products of numerous brands: in addition to Electrolux, the top brands Grand Cuisine, AEG, Zanussi, Frigidaire and Westinghouse enjoy a particularly high reputation.
In 1996, the German AEG brand was acquired from Daimler Benz, together with several divisions and locations of the group. This is how the factory in Rothenburg ob der Tauber, founded in 1964, came to Electrolux, which today produces 600,000 stoves and 1,400,000 cooking ranges per year for the European market.
“We attach great importance to implementing in detail the essential product characteristics of each brand in development and production,” reports Bernd Ebert, director of Global Manufacturing Engineering − Food Preparation at Electrolux. Based in Rothenburg, Ebert ensures that all Electrolux cooking appliance factories implement uniform processes and systems.
As part of a comprehensive digitalization strategy covering all areas, 11 digital manufacturing projects are on the agenda of the Swedish global corporation. Ebert has assumed responsibility for two global projects with the highest priority. They aim to create “digital twins” of all manufacturing sites: In the virtual manufacturing project, an advanced planning tool was selected and introduced for early design verification to develop products that are production- and assembly-friendly. For example, assembly sequences and movements will be planned and optimized three-dimensionally to prevent collisions. The prerequisite for this is the development of three-dimensional factory layouts, which is the focus of the second project, 3D factory layout. The layouts will be created using a standard factory planning tool that can simulate both the plant and the material flow on the basis of 2D data in order to optimize capacity and efficiency.
Software selection began in 2014, when only a few had powerful software for 3D factory planning. A small, specialist team led by Ebert worked closely with the company’s IT department in Stockholm. Starting in 2015, Teamcenter from Siemens PLM Software was deployed there as a strategically important product development platform for product lifecycle management (PLM) at Electrolux.
Discussions about Siemens’ future strategy led to an offer to test a pre-release version of the 3D layout software Line Designer in an early adopter program. more>

Dissecting a submarine network trial announcement
With network infrastructure as critical as submarine cables, we’re constantly seeing new cables being announced and new technological milestones being achieved – but what’s real? Learn the difference between a hero trial, real-world trial, and how you can read between the lines to help separate hype from reality.
By Brian Lavallée – 2019 has and will continue to be a very busy year in the submarine network industry, with several new cables announced, deployed, and already put into the Ready for Service (RFS) state. Why does the industry need so many new submarine cables? To maintain pace with our ever-growing affinity and utter addiction to Internet-based content, which continues to drive the 40% CAGR in intercontinental bandwidth demand, according to industry analysts at TeleGeography, along the submerged information superhighways that interconnect continental landmasses.
As submarine networks are rightfully considered critical infrastructure, deploying new and modern cables will improve the overall reliability of the global network that erases distance and borders to close the digital divide.
When new submarine cable performance milestones are achieved in trials, they’re actively promoted through blogs, press releases, tweets, and webinars to celebrate, and why not? These new submerged wet plant and modem technology advancements are truly astonishing and deserve this fanfare – but the context of these achievements must be fully understood to determine what’s actually deployable for live customer traffic in the real-world.
A “hero field trial” typically uses best-case conditions that are not applicable in the real-world for production traffic, such as using Start-of-Life (SOL) performance margins and not End-of-Life (EOL) performance margins. A “hero trial announcement” can be identified by terms like “evaluation board”, “experimental”, “forward-looking”, “proof of concept”, “demonstration”, “industry first”, and other similar rather vague terms.
A hero trial focuses on demonstrating new capabilities of a technology and/or product albeit without consideration of commercial requirements or conditions. That said, it’s a critical step in the evolution of any new technology.
In contrast to a hero field trial, a “real-world field trial” focuses on demonstrating new capabilities of a technology and/or product albeit with consideration of commercial requirements and conditions. This means that the offering can reliably carry customer traffic and maintain the agreed to Service Level Agreements (SLA) in the long-term. more>
