< Previouswww.networkseuropemagazine.com NEWS IN BRIEF 10 DataQube Global Assume Lead Role in Edge Data Centre Development Project DataQube Global, together with a consortium of construction firms, building architects, structural engineers and facilities management companies, have been appointed by Glendine Developments to redevelop two vacant properties situated on the Viables Business Park in Basingstoke into an edge data centre campus with associated co-working, R&D and recreational facilities. DataQube has also been assigned the role of team lead for this ground-breaking edge development project. The company’s experienced team, guided by David Keegan, CEO at DataQube, will be responsible for overseeing all development stages and ensuring key milestones are achieved. The project, valued at £20 million, forms part of an ambitious regeneration program to encourage a flourishing local community and provide long-term employment opportunities for the wider area. The refurbished properties will comprise cutting-edge research facilities to support medical innovation, technically equipped co-working space and an abundance of public amenities and recreational facilities, including high-spec gymnasium and a 25m swimming pool, to support wellness in the workplace. All data centre services and 5G connectivity requirements will be provided via DataQube’s breakthrough edge data centre system. The first 200KW DataQube module comprising 20 racks will go live in Q3 2022 and will be scaled up in line as the project advances. Keegan said, “DataQube is extremely proud to be chosen as the team lead for this first of its kind project. Glendine are working to deadlines that would be unachievable for regular data centre deployments due to planning/building permission requirements. DataQube’s scalable design and person free layout makes deployment possible within a six-month timeframe.” DataQube is also supporting Glendine in its commitment to maintaining the highest standards of CSR (corporate and social responsibility) and deliver truly sustainable deployments through the system’s highly efficient use of energy. Feasibility studies have shown that DataQube’s person-free layout reduces power consumption by as much as 40% and CO2 emissions by as much as 60% because the energy transfer is dedicated solely to the server racks. Incorporating immersive cooling technology into the system’s core internal infrastructure reduces these figures further. n Celebrating the Achievements of Women in Technology The annual FDM everywoman in Technology Awards have opened for nominations for 2022. The awards aim to celebrate the tech industry’s most exceptional talent, from the UK and beyond, creating role models to inspire the next generation of tech stars. Companies and individuals are invited to put forward candidates until 11 October 2021 for categories recognising all stages of the career journey. Since the awards were founded in 2010, the technology industry has made great steps forward in terms of gender diversity. In 2012 Sheryl Sandberg became the first woman to be elected to the board of directors at Facebook, 2013 saw Megan Smith became the first CTO of the United States and just this year Whitney Wolfe-Herd became the world’s youngest self-made billionaire when she took her online dating business, Bumble, public. The drive to encourage more young girls into STEM subjects has also grown at a rapid rate with the founding of organisations such as Girls that Code. Despite making these strides, the tech industry is facing a recruitment crisis and needs to address its diversity and inclusion to drive future growth. Currently only 24% of people working in STEM in the UK are women and this is only expected to increase to 29% by 2030. This precarious progress has been further destabilised by the events of the past 18 months, with 60% of female STEM students reporting that their career prospects have been affected by the pandemic. Although their numbers are on the rise, women still only account for 10% of leadership roles in the industry. As the country emerges from the Covid-19 crisis, encouraging women into technology is an economic imperative. It’s estimated that to achieve gender parity in the technology sector in the UK, one million women need to be hired and that this shift would benefit the economy by £2.6bn. Research has also shown that gender balanced boards lead to better decision-making, curb excessive risk taking and ultimately bolster a company’s bottom line. This is why the FDM everywoman in Technology Awards and the role they play in creating and leveraging the role models that are needed to attract the finest female talent of the future is of such importance. For 2022, a new category will be introduced. The Cyber Security Award will celebrate a woman who is excelling in her role and making a tangible difference to her business in the field of cyber security. The Tech for Good Award and the CTO/CIO of the Year Award will now be open for international nominations as well as those from the UK. The 2022 FDM everywoman in Technology Awards are free to enter and the ceremony will return as a live dinner in London in March 2022. n If you have news to share, contact: editor@networkseuropemagazine.com Data Centre Summit 2022 With life returning to some sort of new normal, we are working to put in place dates for Data Centre Summit 2022.

In combination with Network Equipment Manufacturers (NEMs), the industry is driving the standards much quicker than we've seen before. Hyperscalers are experimenting while carriers are following in their wake, as they are more focused on price points and are waiting for a point of acceptance from a technology perspective and the change in optics before they start considering migrating to 400G. At the moment, most carriers have not even moved to up to 200G so 400G is still pretty far out for many. The reason why the 400G market is so exciting is that it has unlocked more competition. The 100G silicon space was basically dominated by a single supplier. In one way, this was good for the market in terms of allowing seamless adoption but it also stifled innovation to some degree. When 400G arrived, a lot of the big silicon providers and NEMs started to realise that they could not afford to be limited to a single supplier. 400G has seen a blossoming of both new start-ups and existing participants getting back into the Although much of the hype has been centred on 5G, the power of the new emerging mobile standard – and what comes next – will be intrinsically dependent on the core connectivity within underlying global networks. 400G Ethernet (GbE) is now rolling out mostly HPC and large hyperscalers data centres, while 800G Ethernet is waiting in the wings. Aniket Khosla Vice President Product Management Spirent Are we there yet? ethernet connectivity www.networkseuropemagazine.com 14Examining the current state of play when it comes to next-generation Ethernet connectivity ethernet connectivity www.networkseuropemagazine.com 15silicon market – players like Cisco, Marvel and others now see an opportunity in 400G where they had abdicated 100G. The hyperscalers are not going to slow down because the silicon suppliers can’t keep up. Their business model is based on pushing the boundaries in terms of the different types of technologies that their customers want to consume. Their focus is on looking at a lower cost per bit and they are prepared to explore new options where they can see a clear advantage. As the 400G ecosystem becomes a lot more crowded, the diversity of the ecosystem is good for the customers and for continued innovation. Building blocks Another fundamental shift is within the underlying serial lane technology that is not just impacting 400G but will have a role to play in the adoption of 800G. Standard 100G QSFP28 transceivers do not transmit a single lane of 100Gbps, but instead reach this rate via four lanes of 25Gbps. This became mainstream and gave us a path from 25G to 100G using these fundamental 25G lane building blocks. The single electrical lane of 100G serial is now going mainstream. Whether it's consumed as 100G, 200G, 400G or 800G is less important – the fact that we now have a fundamental building block will provide stability to the market for the next decade. The 200G market that is currently based around 4 x 50G lanes is already slowing down as potential buyers see the rapid evolution of 100G serial lane-based silicon and finished products – which is bringing into question the longevity of any 25G lane-based solution. The 400G space is still small – somewhere in a single digit percentage range of the overall market, and there are two issues holding back adoption. The first is cost, 400g is still expensive when comparing cost-per-bit and the more complex optic situation makes it harder to reach ethernet connectivity www.networkseuropemagazine.com 16mainstream adoption. It is also evident that many potential customers are waiting to see what happens with the evolution of 800G before committing to 400G. However, 400G could experience sharp growth over the next couple of years – with 200G storage an early use case and these applications will endure. However, the incredibly low cost of 100G means that any provider looking to upgrade its network will gravitate to 100G as first choice now due to its evident value and the expansive ecosystem of white box switches and network operating systems. The economics are changing – but there is still hesitation from early adopters at this point in the technology evolution. Optical shift The underlying technologies between 100G using 25G lanes and 400G using 100G lanes are fundamentally different in the way they interconnect. 400G require mandatory Forward Error Correction (FEC) and so the optic and cable ecosystem are different. There is some amount of compatibility between 400G and older 100G transceivers – when running in a pseudo ‘100g mode’ - but this means that the constraints within the ecosystem are also different. One of these is around the fibre plant and the old debate of competing optical transceiver form factors. On one side is QSFP-DD (Quad Small Form Factor – Double Density) and on the other is OSFP (Octal Small Form Factor). In the 100G space, QSFP clearly won. But now, that same debate is starting again in 400G and 800G as in some very early testing OSFP at 800G seems to be performing better in key areas such as size and power consumption. The jury is still out however on QSFP-DD vs OSFP. As 400G products start entering the market – and volumes grow, it is clear that adoption will follow. Although 800G is still going through standards ratification, there is enough maturity for a surge in testing. This is focused around the fundamental 100G lanes and every major silicon vendor alongside a few innovators is ramping up testing to be able to get 800G products to market as IEEE ratification processes conclude. Hyperscalers are also starting the ramp up testing of 100G serial-based solutions. Yet, one of the biggest changes is how closely aligned the different parts of the networking ecosystem are operating within 100G serial lane products irrespective of whether these are 200G, 400G or 800G variants. This is most surprising in the 800G space where there is already a much wider ecosystem of players and higher availability of optics. This is a result of the much more diverse market but also a recognition that there is a potential untapped opportunity to have an 800lb gorilla in the room - so to speak. Testing future Looking to the future, it is clear that 100G based 25G serial lane technology will continue to have a very long tail. The low cost and maturity in the market are hard to displace quickly. In my view, 400G will have a modest adoption over the next three to five years but 800G will start to eat its lunch at this point due to sharing the same underlying technology foundations. So lastly, let’s look at the evolution of testing. It is clear that the generation of technologies based on 100G serial lanes will be much more diverse than that 100G/25G lane situation where at a silicon level, a single dominant player has a 70%+ market share. Competition and diversity are great for customers and innovation but this means that customers are not just evaluating one core silicon vendor: now it’s potentially three or four different vendors working together in a mixed ecosystem. This means that there will be inconsistency in performance and potentially interoperability issues and things could go wrong. The other major issue is backwards compatibility. Eventually, all the silicon coming to power 800G systems will need to support standards all the way down to 10G. The mix and match nature of modern networks mean that performance can vary dramatically. Add in the newly mandated features like FEC and the constant flow of firmware updates, and the need for validation testing is dramatically increased. The last element is that with a bigger ecosystem, the need for independent accountability within testing is vital. In a world where “white box” solutions are growing and Network Operating Systems are the norm, there is a danger in the 400/800 space for more finger-pointing between vendors where there is an issue – only third-party testing and validation can uncover the true root cause which may reside at the underlying silicon layer. In summation, the networking space is incredibly exciting and the wealth of new vendors entering the space will offer many benefits for customers – and for ongoing innovation across the industry. The network is the lifeblood for society and looking at the bigger picture, it is clear that more continuous testing will become the new normal and that shift is being accelerated by this next leap to 400G and 800G. n One of the biggest changes is how closely aligned the different parts of the networking ecosystem are operating within 100G serial lane products irrespective of whether these are 200G, 400G or 800G variants. ethernet connectivity www.networkseuropemagazine.com 17What does the mean for the edge www.networkseuropemagazine.com 18 Peter Ruffley CEO Zizo In addition, especially when it comes to the reality of industrial IoT, the cost, time and disruption that goes into a brand new facility – the prospect of having to rip and replace new infrastructure to support IoT just isn’t a viable option for many businesses. So what’s the alternative? Peter Ruffley, CEO, Zizo, explains how edge IoT and analytics can provide a powerful mechanism for translating complex data sources into a streamlined, lower cost platform with a faster return on investment and higher value. First, he considers some of the key challenges businesses face when considering an investment in IoT. Investment The transformational potential of IoT across multiple industries is staggering and much has been discussed about its power to revolutionise business models. But while the possibilities for market sectors are hugely exciting, the reality of many of these industry IoT solutions is that they are designed for vast use cases – the setups are intricate and complex, with incredibly powerful networking capabilities that require significant investment and skill to execute. In addition, the major players in the IoT space, including AWS and Microsoft, require huge upfront investment into IoT stacks and other hardware integrated into the data centre, as well as the personnel who can code the solution, write it and build it – that’s potentially hundreds of thousands of pounds even before any potential data or insight has been gained. Return on investment is something that has been lacking within the IoT space, causing proof of concepts to fail. When you consider one of the early use cases for IoT – smart meters – in that instance it’s simple to work out the ROI as you don’t A lot has been written about the IoT revolution and how the technology has the capability to revolutionise industries, transform productivity and unlock new levels of insight. But for those intrigued by the possibilities and looking to dip their toe in the water, the potential myths of high price point, infrastructure and connectivity challenges, as well as the required skill set can be significant hurdles that seem insurmountable. at does the edge an for IoT? the edge www.networkseuropemagazine.com 19Next >
